Find the missing values in the equation below.
Line 1: 2/3 - 1/2 = 4/?-?/6
Line 2: / - / = ?/6
Answer:
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4}{6} - \frac{3}{6}[/tex]
[tex]\frac{2}{3} - \frac{1}{2} = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4}{?} - \frac{?}{6}[/tex]
[tex]/ - / = \frac{?}{6}[/tex]
Required
Fill in the gaps
For Line 1, convert both fraction to a denominator of 6.
This is shown below:
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4}{?} - \frac{?}{6}[/tex]
[tex]\frac{2}{2}*\frac{2}{3} - \frac{1}{2} *\frac{3}{3}[/tex]
[tex]\frac{2*2}{2*3} - \frac{1*3}{2*3}[/tex]
[tex]\frac{4}{6} - \frac{3}{6}[/tex]
Hence:
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4}{6} - \frac{3}{6}[/tex]
For Line 2;
We have:
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4}{6} - \frac{3}{6}[/tex]
[tex]\frac{2}{3} - \frac{1}{2} = \frac{4-3}{6}[/tex]
[tex]\frac{2}{3} - \frac{1}{2} = \frac{1}{6}[/tex]
In equation form. What goes through the points (0, 4) and (2, 7)?
Answer:y=1.5x+4
Step-by-step explanation:
A line passes through the point (-8,-5) and has a slope of 3/4. Write an equation in slope intercept form for this line.
Answer:
y = ¾x + 1
Step-by-step explanation:
Point-slope equation for line of slope ¾ that passes through (-8,-5):
y+5 = ¾(x+8)
Put into slope-intercept form:
y = ¾(x+8) - 5 = ¾x + 6 - 5 = ¾x + 1
A bag of marbles contains 2 white, 3 black, 1 red and 4 blue marbles. Cate draws one marble from the bag, looks at it and then replaces it. What is the probability that she will draw a black marble and then a black marble?
A) 9/10
B) 9/100
C) 3/5
D) 1/25
Step-by-step explanation:
Number of black marbles = 3
Total number of marbles = 2 + 3 + 1 + 4 = 10
P(Drawing a black marble) = 3/10
Since the drawing is replaced,
they are considered independent events.
=> P(Black marble, following by black)
= [P(Drawing a black marble)]²
= (3/10)²
= 9/100. (B)

Write the equation x2 + 6x + y2 – 8y = 19 in standard form.
Question 11 options:
1)
(x + 3)2 + (y – 4)2 = 44
2)
(x + 3)2 + (y – 4)2 =
3)
(x – 3)2 + (y – 4)2 =
4)
(x + 3)2 + (y + 4)2 = 44
Answer:
i think its 2
Step-by-step explanation:
The equation of x² + 6x + y² - 8y = 19 in standard form is (x + 3)² + ( y - 4)² = 44. Hence, Option A is the correct answer.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We have been given the equation as;
x² + 6x + y² - 8y = 19
We need to find the standard form of the equation.
Thus, we have,
(x² + 6x )+(y²- 8y) = 19
We shall complete the square for the term;
(x² + 6x + 9 - 9 ) + (y² + 4y + 16 - 16) = 19
Simplifying, we get,
(x² + 6x + 9) - 9 + (y²- 8y + 16) - 16 = 19
(x² + 6x + 9) - 9 + (y²- 8y + 16) - 16 = 19 + 9 + 16
Formula used :
x²+2xy+y² = (x+y)²
x²-2xy+y² = (x-y)²
Simplifying, we get,
(x + 3)² + ( y - 4)² = 44
Thus, the equation of x² + 6x + y² - 8y = 19 in standard form is (x + 3)² + ( y - 4)² = 44.
Hence, Option A is the correct answer.

Determine whether the points on the line rise, fall, are horizontal, or vertical.
(2, -4) and (4, -1)
Answer:
The points rise.
Step-by-step explanation:
Points on a line have the following format: (x,y)
They rise if: As x increases, so does y.
They fall if: As x increases, y decreases.
They are horizontal if: As x increases, y remains constant.
They are vertical if: x is constant as y changes.
In this question:
Points (2,-4) and (4,-1).
x increases from 2 to 4.
y increases from -4 to -1.
That is, both increase, so the points rise.
Solve for x.

Solve the inequality
Answer:
P > 9
Step-by-step explanation:
22 x 9 would equal 198 also, but if you want it to be like in the equation where 22p is more than 198 it has to be more than 9. So if you were to substitute any number over 9 it would work.
Julio says,”If you subtract 15 from my number and multiply the difference by -7,the results is -175.” What is Julio number
Answer:
Julio's number is 40.
Step-by-step explanation:
We need to reverse the operations Julio performed on his number. First, we divide -175 by -7, and we get 25. Then, we add 15 to that, giving us Julio's number of 40.

what linear equation in slope intercept from does this graph represent?
Answer:
[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]
Step-by-step explanation:
The equation of a line is [tex]y = mx + b[/tex], with [tex]m[/tex] being the slope and [tex]b[/tex] being the y-intercept.
We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is [tex]y = mx + 100[/tex].
Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).
Then, we'll use [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1} }[/tex] to find the slope.
Let's substitute in our points.
[tex]\frac{150-100}{3-0}[/tex]
Simplify.
[tex]\frac{50}{3}[/tex]
Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is [tex]16\frac{2}{3}[/tex].
We'll put that in our equation for a line and...bam!
[tex]y = 16\frac{2}{3} x + 100[/tex] or [tex]y = \frac{50}{3} + 100[/tex]
Two siblings are racing. The older sibling can run at a constant speed of 11 feet per second. The younger sibling can run at a constant speed of 7 feet per second. If the younger sibling is given a 32-foot head start in the race, how long will it take the older sibling to catch the younger sibling, and how far will the older sibling have run at that moment?(1 point)
The older sibling will catch the younger sibling after ___ second(s) and running___feet.
Answer:
8 seconds after running 88 feet
Step-by-step explanation: this is what it told me the answer was
Answer:
The older sibling will catch the younger sibling after 8 second(s) and running 88 feet.
Step-by-step explanation:
Older Sibling: 11ft 22ft 33ft 44ft 55ft 66ft 77ft 88ft
Younger Sibling: 32ft 39ft 46ft 53ft 60ft 67ft 74ft 81ft
The younger sibling started at 32ft because of the headstart. Each number was after 1 second. So this means it took 8 seconds for the older sibling to get to 88ft, and it took 8 seconds to get the younger sibling to 81ft.
I hope you can understand. :)
What is the area of the region bounded by the lines x= 1 and y= 0 and the curve y=xe^x^2?
Answer:
A = 0.859
Step-by-step explanation:
We want to find the area of the region bounded by the lines x = 1 and y = 0 and the curve y = xe^(x²).
At y = 0, let's find x;
0 = xe^(x²)
Solving this leads to no solution because x is infinity. Thus we can say lower bound is x = 0.
So our upper band is x = 1
Thus,lets find the area;
A = ∫xe(x²) dx between 1 and 0
A = (e^(x²))/2 between 1 and 0
A = ((e¹)/2) - (e^(0))/2)
A = 1.359 - 0.5
A = 0.859

Step-by-step explanation:
3a – 8 = 5a + 12
3a – 8 + 8 = 5a + 12 + 8
3a = 5a + 20
3a - 5a = 5a + 20 - 5a
- 2a = 20

2/8 simplified is 1/4
Answer:
The answer will be 2/8 because if you think about it 4/8 is 1/2 and 1/2 of 4/8 is 2/8 and since 1/2 4/8 is 2/4 which is actually 1/2 of 1/2 so that makes it 1/4 hope this helps!!

-4x + 12 = -6x
Step 1: Add 4x to both sides:
12 = -6x + 4x
Step 2: Combine like terms:
12 = -2x
uh- this is the correct way to answer the problem....
−4x+12=−6x
Step 1: Add 6x to both sides.
−4x+12+6x=−6x+6x
2x+12=0
Step 2: Subtract 12 from both sides.
2x+12−12=0−12
2x=−12
Step 3: Divide both sides by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-12}{2}[/tex]
x=−6
