Answer:
x=4
Step-by-step explanation:
helpppppp. (the other one cut out is multiplication property of equality)
Answer:
The second step is Distributive Property and the third is Subtraction Property of Equality
Step-by-step explanation:
The 1/2 is being distributed in the second step making the 8x to 4x and the 6 to 3.
The third step involves the subtraction of "x" from the right hand side and the left hand side.
Please look at number 13. and use the slope and write the equation for me
Answer:
y - y1 = m(x - x1)
(x1, y1) = (1, -1) (x2, y2) = (3, 5)
m = [tex]\frac{5 - (-1)}{3 - 1}[/tex]
m = [tex]\frac{5 + 1}{3-1}[/tex]
m = [tex]\frac{6}{2}[/tex] = [tex]\frac{3}{1}[/tex] = 3
m = 3
y - 5 = 3(x - 3)
y - 5 = 3x - 9
y = 3x - 9 + 5
y = 3x - 4
Step-by-step explanation:
In order to use point-slope form to convert to slope-intercept form you have to know one point and the value of the slope. In this case, we know two points, but we don't know the slope. In order to find the slope, you can input the values of the two points into the expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
After finding the slope, input the values of one of the points (in this example I used (3,5)) and the slope. After that, multiply the slope by the two terms inside the parentheses. then add 5 to both sides of the equation to isolate y. Now your equation is in slope-intercept form.
I hope this helps :)
Divide. Write your answer as a fraction or mixed number in simplest form.
9 1/3 • 7
Answer:
65 1/3 or 196/3
Step-by-step explanation:
9 1/3 can be written as 28/3 (9 times 3 plus 1)
28/3 times 7/1 (because any whole number can have a 1 as the denominator)
Multiply top to top and bottom to bottom
28 times 7/ 3 times 1
196/3
Simplify to
65 1/3 but 196/3 will work out as well

Factorise:x2-3x-40 find this answer fast
This trinomial is in a special form that can be
factored into the product of two binomials.
So we set up two sets of parenthses.
As the first term, we have the factors of x², x and x.
For the second term, we have the factors of -40 that add to -3.
In this case, these factors are -8 and +5.
So our answer is (x - 8)(x + 5).
The polygons below are similar. Find the scale factor of the SMALLER figure to the LARGER.
A. 5:6
B. 3:5
C. 5:8
D. 2:5
Answer:
A. 5:6
Step-by-step explanation:
The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.
Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.
Therefore:
Scale factor = 25:30
Simplify
Scale factor of the smaller figure to the larger = 5:6

f(x)=4x+7. Find the inverse of f(x).
A.{f^{ - 1}}\left( x \right) = \frac{{x - 7}}{4}f −1 (x)= 4x−7
B.{f^{ - 1}}\left( x \right) = 7 - 4xf −1 (x)=7−4x
C.{f^{ - 1}}\left( x \right) = \frac{{x - 4}}{7}f −1 (x)= 7x−4
D.{f^{ - 1}}\left( x \right) = 4x - 7f −1(x)=4x−7
it a i need for later
Answer:
Step-by-step explanation:
f(x) = y = 4x + 7
Solve for "x"
4x + 7 = y ⇒ x = [tex]\frac{1}{4}[/tex] y - [tex]\frac{7}{4}[/tex]
Exchange the places "x" and "y"
[tex]f^{-1}[/tex](x) = [tex]\frac{1}{4}[/tex] x - [tex]\frac{7}{4}[/tex]
or [tex]f^{-1}[/tex] (x) = [tex]\frac{x-7}{4}[/tex]
5) 36% of 68.1 is what?
Answer:
I'm pretty sure it's 24.516
Answer/Step-by-step explanation:
36% of 68.1 is 24.516.
1. To find a percentage of a number, turn the percentage into a decimal that is represented out of 100% where 1 is equal to 100%.
36% is represented as 0.36.
2. Now, multiply that decimal by the number.
68.1 x 0.36 = 24.516
This leaves us with the answer.
A worker has four different job offers, each with a contract for six years. Assuming the job descriptions are identical,
which offer will allow the worker to earn the most over six years?
O a starting salary of $49.000 with a 3% increase each year
O a starting salary of $51 000 with a 1% increase each year
O a starting salary of $48,000 with a 6% increase each year
a starting salary of $50,000 with a 2% increase each year
9514 1404 393
Answer:
$48,000 to start, with 6% raises
Step-by-step explanation:
The starting salaries are within a few percentage points of each other, so the majority of the difference in earnings will come because of the raises. The offer with the largest raise percentage is likely the best.
The earnings total can be figured as the sum of a geometric series with a first term of "starting salary" and a growth factor of (1+raise percentage). For starting salary 's' and raise percentage 'r', the total earnings in 6 years will be ...
S = s((1+r)^6 -1)/r
Here are the total earnings, in thousands, for each of the offers:
a) s = 49, r = .03, S = 316.95
b) s = 51, r = .01, S = 313.75
c) s = 48, r = .06, S = 334.82 . . . . best offer
d) s = 50, r = .02, S = 315.41
The worker can earn the most from a starting salary of $48,000 and 6% increases each year.
C) a starting salary of $48,000 with a 6% increase each year
The point (0, 0) is a solution to which inequality? A. y – 9 3x + 10 C. y – 9 > 3x – 10 D. y + 9 > 3x + 10
Let x = 0
Let y = 0
Look at choice A. There is a typo here. This is not an inequality. Where is choice B? No choice B given.
Let us play with choice C and D.
y - 9 > 3x - 10
0 - 9 > 3(0) - 10
-9 > 0 - 10...This is a true statement. We know that -9 is bigger than -10. Do you know why this is true?
How about D?
Again let y = 0 and x = 0.
0 + 9 > 3(0) + 10
9 > 0 + 10
9 > 10...This is untrue. We know that 9 is NOT BIGGER than 10.
Without knowing A and B, I figured out that choice C is true. We conclude that the point (0,0) AKA the origin is a solution to the inequality given by choice C.

Two square rooms have a total floor area of 89m2. One room is 3m longer each way than the other. Find the dimensions of the two rooms. A. 5m square and 8m square B. 4m square and 6m square C. 5m square and 12m square D. 6m square and 8m square
Answer:
A
Step-by-step explanation:
Let the smaller room have an area of x^2
Let the larger room have an area of (x + 3)^2
(x+3) ^2 + x^2 = 89 Be careful not to make it 89^2.
x^2 + 6x + 9 + x^2 = 89 Expand the binomial squared
2x^2 + 6x + 9 - 89 = 0 Subtract 89 from both sides
2x^2 + 6x + 9 - 89 = 0 Combine
2x^2 + 6x - 90=0 Divide by 2
x^2 + 3x - 45 = 0 This factors.
(x + 9)(x- 5) = 0
X + 9 gives nothing useful
x - 5 = 0
x = 5
x + 3 = 5+3 = 8

Nika baked three loaves of zucchini bread. Each loaf needed StartFraction 17 over 4 EndFraction cups of flour. Which expression shows the best estimate of the number of cups of flour that Nika used?
4 + 4 + 4 = 12
5 + 5 + 5 = 15
4 + 4 + 4 = 16
17 + 17 + 17 = 51
Answer: It is A
Step-by-step explanation:
17/4 = 4 1/4
so each cake needs 4 1/4 cups of flower.
Now, the question asks what the best estimate of the total number of cups is.
It could be A or C because 4 1/4 is closer to 4, but...
we need to figure out if 4 1/4 + 4 1/4 + 4 1/4 (we need to make three cakes) is closer to 12 or 16.
4 1/4 + 4 1/4 + 4 1/4 = 12 3/4
Ask yourself: is 12 3/4 closer to 12 or 16?
12 3/4 is closer to 12 so the answer is A.
A student club started a fundraising effort to support animal rescue organizations. The club sent an information flyer home to the rt students in the school. It says, "We welcome donations of any amount, including any change you could spare!" Their goal is to raise T' dollars, and to donate to a cat shelter and a dog shelter, On the next page, match cach quantity to an expression, an equation, or an inequality that describes it The dollar amount the club would have if they reached one-fourth of their goal. The dollar amount the club would have revery student at the school donated a quarter to the cause. The dollar amount the club could donate to the cat shelter if they reached their goal and gave a quarter of the total donation to a dog shelter. The dollar amount the club would still need to raise to reach its goal after every student at the school donated a quarter. The dollar amount the club would have all three-fourths of the students at the school each gave 50 cents 3
Answer:
1. 0.25T
2. 0.25n
3. T - 0.25T
4. T - 0.25n
5. 0.75n × 0.5
Step-by-step explanation:
1. The dollar amount the club would have if they reached one-fourth of their goal.
Since the goal is to raise T dollars
One-fourth of T = ¼ × T = 0.25T
2. The dollar amount the club would have if every student at the school donated a quarter to the cause.
Let the number of students in the school be n
Since there are n students in the school, amount raised = ¼ × n = 0.25n
3. The dollar amount the club could donate to the cat shelter if they reached their goal and gave a quarter of the total donation to a dog shelter.
Since they reached their goal, the total amount they raised= T dollars
They gave a quarter of the total donation to a dog shelter = ¼T = 0.25T
Amount left to donate to the cat shelter = T - 0.25T
4. The dollar amount the club would still need to raise to reach its goal after every student at the school donated a quarter.
Amount donated if every student donated a quarter = ¼n = 0.25n
Amount still needed = T - 0.25n
5. The dollar amount the club would have if three-fourths of the students at the school each gave 50 cents
Three-fourths of the students = ¾n = 0.75n
50 cents = 0.5 dollars
Amount raised if three-fourths of the students gave 50 cents = 0.75n × 0.5
