Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)
m =
= - 
Answer:
2x+3+7x=-24 (combine like terms)
9x+3=-24
9x=-27
x=-3
Step-by-step explanation:
We can evaluate the given expression by using the order of operation. So,
2 + 32 ⋅ (4 − 1)
Step 1: Operate the parenthesis part.
So, 2 + 32 ⋅ (4 − 1)= 2 + 32 ⋅ 3
Step 2: Next step is to multiply.
2 + 32 ⋅ 3= 2+ 96
Step 3: Add.
2+96=98.
Answer:
C 7ft/yr
Step-by-step explanation:
The given points are not all on the same line, so the average will vary depending on the interval of interest.
Over the interval [1, 11] years, the average rate of change of height is ...
change in height / change in years = (80 -10)/(11 -1) = 70/10 = 7 . . . ft/yr
__
On the interval [11, 15] years, the average rate of change is ...
(105 -80)/(15 -11) = 25/4 = 6.25 . . . ft/yr
Even on this interval, the closest answer choice is C.
