which leaner equation represent the graph
Answers
Step-by-step:
The points graphed are (0,-2) and (-1,1)
We can see that the point goes up by 3 and left by 1. Because the line is in hemispheres 2 and 4 mostly, it is a negative line.
The equation to find the coefficient of the variable x is rise/run. The line rises up three, and runs left negative. This makes that equation 3/-1, or simply -3 when simplified.
To find the term, we have to find where the line crosses the y axis. That’s when the x value of the point is 0. (0,-2) is where the line crosses the x axis, making the term -2.
So, y= -3x - 2

X-Y=3
2x+2y=50
Answers
Answer:
abcdefg
Step-by-step explanation:
Answer:
x = 14
y = 11
Step-by-step explanation:
x - y = 3
2x + 2y = 50
multiplty x - y = 3 by two so we can get an equal value
2x - 2y = 6
2x + 2y = 50
-2y and 2y can be cancled out. That means we don't need to change any signs and we can add everything exept 2y and -2y becuase they will be cancled out.
4x = 56
Divide each side by 4 to leave x alone.
x = 14
Now that we know the x value, take one of the equations in the question and plug it in. I am going to use the equation x - y = 3 to make it easier.
14 - y = 3
-y = 3 - 14
-y = -11
y = 11
Now we know that y = 11.

Explain how you can find the volume of the figure below. Then, solve- what is the volume of the figure? Make sure to include your units
Answers
Answer: a) The figure can be reasonably divided into two geometries:
• a rectangular prism
• a hemisphere.
b) The volume of the rectangular prism is given by
V = lwh
V = (10 cm)(5 cm)(4 cm) = 200 cm³
The volume of the hemisphere is given by
V = (2π/3)r³
V = (2π/3)(3 cm)³ = 18π cm³
c) The total volume of the figure is
total volume = (prism volume) + (hemisphere volume)
V = 200 cm³ + 18π cm³
V ≈ 256.549 cm³

Tristan is selling plastic and wooden picture frames. He sells 7 frames total. The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames. How many of each type of frame does Tristan sell?
Answers
Answer:
4 wooden and 3 plastic
Step-by-step explanation:
4 (wooden) × 2 - 5 = 3 plastic
3 (plastic) + 4 (wooden) = 7 total
The number of plastic frames is 4 and the number of wooden frames is 3.
What is equation?
A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given statement:
The number of plastic frames Tristan sells is 5 less than twice the number of wooden frames.
The total number of frames sold by Tristan is 7.
Write the equation for the above statement,
p = 2w - 5
Here, p is a plastic frame and w is a wooden frame,
p + w = 7
Solve the equation by using the elimination method,
p = 4 and w = 3
Therefore, the number of plastic frames is 4 and the number of wooden frames is 3.

What does x =
Answers
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
Add 8x to both sides
-15x + 8x - 40 = 23
-7x - 40 = 23
Add 40 to both sides
- 7x = 23 + 40
-7x = 63
Divide both sides by (-7)
x = 63/-7
x = -9
Answer:
x = -9
Step-by-step explanation:
-15x - 40 = 23 - 8x
add 8x to both sides to bring -8x to the left side
-15x + 8x - 40 = 23
add 40 to both sides to bring -40 to the right side
-15x + 8x = 23 + 40
add the common terms
-7x = 63
for x to be alone divide -7 to both sides
x = -9

-2(4r - 6) Mathhhhhhhhh pls
Answers
Answer: -8r+12
Step-by-step explanation:
============================================
Explanation:
The outer term -2 is multiplied by each term inside
-2 times 4r = -8r-2 times -6 = 12Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.
I used the distribution property, also known as the distributive property.
That says a*(b-c) = a*b - a*c
In this case, a = -2, b = 4r, and c = 6.
Two pools were being filled. Pool A was being filled 1/8 of a gallon in 1/12 of a minute, and pool B was being filled at 3/8 of a gallon in 1/9 of a minute. Which pool is being filled up faster?
Answers
V=d/t
V1=1/8 × 12/1=12/8=3/2
V2=3/8 × 9/1 =27/8
Common denominator:
3/2=1 1/2 and 27/8= 24 3/8
so second pool because 24 3/8 is greater
