VW = VC + CW
61 = z + 13 + z + 8 = 2z + 21
2z = 61 - 21 = 40
z = 40/2 = 20
z = 20.
Gotchu my dude
Cone - v=1/3Bh
Cylinder- v=Bh
Triangular prism - v=1/3AH (where A is the triangle base) h is the height of the pyramid
Rectangular prism- v=whl
Pyramid-lwh
I rlly hope this helps and try to match them i know mine are different
Answer:
The answer to your question is (-4, 9) and (3, 2)
Step-by-step explanation:
Data
Equation 1 y = x² - 7
Equation 2 y = -x + 5
Process
1.- Substitute Equation 2 in equation 1
-x + 5 = x² - 7
2.- Equal to zero
x² + x - 7 - 5 = 0
x² + x - 12 = 0
3.- Factor to find x
(x + 4)(x - 3) = 0
x₁ + 4 = 0 x₂ - 3 = 0
x₁ = -4 x₂ = 3
4.- Substitute x₁ and x₂ to find y
y = -x + 5 x₁ = -4
y = -(-4) + 5
y = 4 + 5
y = 9 Solution (-4, 9)
y = -x + 5 x₂ = 3
y = -3 + 5
y = 2 Solution (3, 2)
Answer:
y=3x-5
Step-by-step explanation:
Slope intercept form is y=mx+b
m represents slope
b represents y-intercept
In the picture, 3 replaces m, so 3 is the slope of the line.
When (2,1) and (5,10) are graphed, the line intercepts -5 on the y axis.
-5 is the y-intercept.
So, (2,1) and (5,10) in slope-intercept form is
