Please help.
Answer:
y=2x-1
Step-by-step explanation:
Gradient : (7-3) / (4-2) = 2
y=2x+c
substitute one of the points
3=2*2+c
c=-1
y=2x-1
I need help with solving for x please
Answer:
1. x = 16
2. 2x + 9 = 41
Step-by-step explanation:
So this is the first step.
2x + 9 + 3x + 1 = 90 (collect like terms)
5x + 10 = 90 (subtract 10 on both sides)
5x = 80 (divide by 5 on each side)
x = 16
Plug in to 2x + 9
2(16) + 9 =
32 + 9 =
41 = 2x + 9
Hope this helps! Have a blessed day!
which point is collinear to the point (0,0)?
A) (1,0)
B) (3,2)
C) (4,1)
D) (1,3)
Answer:
All of them are right
Step-by-step explanation:
Are you sure the question was that?
Collinear means that it lies on the same line
Now, from every 2 points passes a unique line
So(0,0) and (3,2) are in a line
(0,0) and (1,0) are in an other line and so on
y-2 = -3(x + 6), write the equation of the line in slope intercept form.
Answer:
y = -3x - 16
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: y - 2 = -3(x + 6)
Slope-intercept form: y = mx + b
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).
To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:
y = mx + b
2 = -3(-6) + b
2 = 18 + b
Subtract 18 from both sides of the equation to isolate b:
2 - 18 = 18 - 18 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = -3x - 16
Find the unit rate. $30 for 2 1/2 hours of work
Answer:
12$ an hour.
Step-by-step explanation:
Simply set it up as fraction in a way set it as 30/2.5 and divide both values by 2.5 which you get 12 from 30 and 1 from 2.5 there's your unit rate. 12/1 or 12$ an hour.
Which could be a step used when solving the equation 2x−5=1/3x
Answer:
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = 3
Step-by-step explanation:
Multiply both sides by 3. I take it mean 1/3 * x and not 1/(3*x) which puts x in the denominator.
6x - 15 = (1/3) x * 3 Cancel on the right.
6x - 15 = x Subtract 6x from both sides.
6x - 6x - 15 = x - 6x Collect light terms
- 15 = - 5x Divide by - 5
-15/-5 = -5x/-5
x = 3
Weights of different materials were taken for three lengths: 6 inches, 12 inches, and 18 inches. Which of the materials' weights does NOT have a proportional relationship with length?
The question is incomplete, the complete question is shown in the image attached.
Answer:
Material 1
Step-by-step explanation:
Given the table shown in the complete question, we can see that the weights in material 1 does not have a proportional relationship with length.
If something has a proportional relationship, then it increases or decreases by a constant value called the constant of proportionality. This is not the case in material 1 as seen from the table.
Answer:
material 1

Answer:
42
Step-by-step explanation:
[tex]41^{2}[/tex] + [tex]9^{2}[/tex] = [tex]c^{2}[/tex]
So, what's 41 to the power 2?
Thus;
1,681
Do the same for the other one.
9 to the power of 2
Thus;
81
Add all these up all your final answer to get a total of 1,762.
1681+81=1762
Thus;
[tex]c^{2} = 1762[/tex]
Then square root your final answer
[tex]\sqrt[]{1762}[/tex]=[tex]c^{2}[/tex]
Thus;
42= [tex]c^{2}[/tex]

==========================================
Work Shown:
4/9 + 9/18
8/18 + 9/18 ... see note below
(8+9)/18
17/18
----------------
note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.
The diagram below shows a visual representation of why 4/9 = 8/18.
In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
Answer: its 17/18

18. Two planes left an airport at the same time. One flew north at a set speed and the other
flew south at one-and-a-half times the speed of the other plane. Three hours later the planes
were 2400 miles apart. How fast was each plane flying?
Answer: plane A = 333.33mph
Plane B = 500mph
Step-by-step explanation:
Given data:
Distance between the two planes = 2400miles.
Plane A flew North
Plane B flew south
Solution:
Let v represent plane A.
Let 2v represent plane B.
Distance between the two plane
v + 1.5* v = 3*v
7.5v = 2500miles
v = 333.33mph
Plane B has one and half times the speed of plane A
= 1.5 * 333.33
= 500mph

Step-by-step explanation:
A family wants to purchase a house that costs $145,000. They plan to take out a $115,000 mortgage on the house and put $30,000 as a down payment. The bank informs them that with a 15-year mortgage their monthly payment would be $785.99 and with a 30-year mortgage their monthly payment would be $521.41. Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage. How much would they save if they selected the 15-year mortgage?
Answer:
A. 15-year mortgage =$141,478.20
30-year mortgage =$187,707.60
B. $46,229.40
Step-by-step explanation:
A. Calculation to Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage.
Calculation for 15-year mortgage
Cost amount to save for 15-year mortgage=$785.99*15-year*12 months
Cost amount to save for 15-year mortgage =$141,478.20
Calculation for 30-year mortgage
Cost amount to save for 30-year mortgage =$521.41*30-year*12 months
Cost amount to save for 30-year mortgage =$187,707.60
B. Calculation for How much would they save if they selected the 15-year mortgage
Using this formula
Amount to save=30-year mortgage -15-year mortgage
Let plug in the formula
Amount to save=$187,707.60-$141,478.20
Amount to save=$46,229.40
Therefore How much would they save if they selected the 15-year mortgage will be $46,229.40

!!!!!!!!!
Step-by-step explanation:
1. (4m² - 1.5m + 2) + (9m - 2m³ + 2m)
= 4m² - 1.5m + 2 + 9m - 2m³ + 2m
= 4m² + (-1.5m + 9m + 2m) + 2 + 2m³
= 4m² + 9.5m + 2 + 2m³
= 2m³ + 4m² + 9.5m + 2
2. (-3y + 2y² - 6) + (3y + 4y² + x)
= -3y + 2y² - 6 + 3y + 4y² + x
= (-3y + 3y) + (2y² + 4y²) - 6 + x
= 0y + 6y² - 6 + x
= 6y² - 6 + x
