Answer:answer is 37
Step-by-step explanation:
2x+1=75
2x=75-1
2x=74
x=74/2
therefore, x=37
F(8)=4(8)-2+7(8)
f(8)=32-2+56
f(8)=86
f(-5)=4(-5)-2+7(-5)
f(-5)=-20-2+2
f(-5)=20
f(0)=4(0)-2+7(0)
f(0)=0-2+0
f(0)=-2
Answer:
Part 1) The height of triangle is 
Part 2) The width of rectangle is 
Step-by-step explanation:
step 1
Find the dimensions of triangle
The area of triangle is equal to

we have


substitute and solve for h



step 2
Find the missing dimension of rectangle
we have that
The height of the triangle is the same as the width of the rectangle
therefore

Answer:
y= -5(x-4)
Step-by-step explanation:
any point slope equation is in form y-y1 = m(x-x1)
plug in the point and constant value
y-0 = -5(x-4)
y= -5(x-4)
