Answer:
y=4x-28
Step-by-step explanation:
slope is 4
y-4=4(x-8)
y-4=4x-32
y=4x-32+4
y=4x-28
the slopes of parallel lines are equal
Answer:
x=3/5 or 0.6
Step-by-step explanation:
Volume of a cylinder is formulated as: π·r²h
Surface area of a cylinder is formulated as: 2π·rh + 2π·r²
So, for a:
Volume = π·5²·12 = π·25·12 = 300π
Surface area = 2π·5·12 + 2π·5² = 120π + 50π = 170π
And it's essentially the same process for the other questions.
I count 5. There could be more. Sorry. Don't have scratch paper at the moment.
Answer:
y = 2x - 2
Step-by-step explanation:
y = mx + b
Sub x = 5, y = 8, and b = -2 into the equation.
8 = 5m - 2
Isolate the m-term and solve for m.
8 + 2 = 5m -2 + 2
10 = 5m
Divide both sides by 5 to isolate m.
m = 2
Sub the parameters (m and b) into the template to get your equation.
y = 2x - 2
