Answer:
12 in
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(b₁ + b₂ )
where h is the height and b₁, b₂ the parallel bases
Given h = 6, b₁ = 8 and A = 60 , then
× 6 × (8 + b₂ ) = 60 , that is
3(8 + b₂ ) = 60 ( divide both sides by 3 )
8 + b₂ = 20 ( subtract 8 from both sides )
b₂ = 12
The length of the second base is 12 inches

Answer:
Y=1/3x-1 is the correct answer in slope intercept form:)
Hopefully! this help.
Step-by-step explanation:
Answer:
y=-1/4x+2
Step-by-step explanation:
So the forumla for slope/intercept equation is:
y=mx+b
Y equals the y coordinates on the graph. This is the value that you plug in x to solve for.
m equals the slope of the graph. (In this case -1/4)
x equals the x coordinates. This will always be just x when writen in a slope intercept equation, since x is the value you plug in to solve for y.
b equals the y intercept. This is different from the y coordinates. This is a known value, which can be found when x=0. (In this case 2)
Now, using this lets plug in our numbers for the differet variables:
y=mx+b
We know that m, the slope, is -1/4. So:
y=-1/4x+b
We also know that b, the y inteercept, is 2. Since we have the coordiantes (0x, 2y). So:
y=-1/4x+2
This is all you have to do! This is because y is the number you solve for, and x is the value you plug.
Hope this makes sense and helps! :)
I think by p, you mean x.
x-4=9
move the four
x=13
