Answer:
- 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = 
= 
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= -
Answer:
b
Step-by-step explanation:
b should be done first because of PEMDAS which justifies you have to take everything out of parenthesis
the answers are
the bases are congruent,
the volume of the first solid is twice as much as the volume of the second solid,
and
if the dimensions of the second solid are x by x by h, the first solid has 4xh more surface area than the second solid
(I just did this assignment)
9 + 1/2 (7n - 26) - 8n
Expand brackets by multiplying by 1/2:
9 + 3.5n - 13 - 8n
Collect like terms:
4.5n - 4
Turn it into an equation:
4.5n - 4 = 0
Isolate 4.5n by adding 4 to both sides:
4.5n = 4
Divide both sides by 4.5 to get the value of n:
n = 8/9
Write the question down I can't see that
