Answer:
14,784
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
10+4 is 14 amd 14-4 is 10
Subsitute -4y for x
-4y+6y=18
2y=18
divide both sides by 2
y=9
sub back
x=-4y
x=-4(9)
x=-36
(x,y)
(9,-36)
Answer:
6 units
Step-by-step explanation:
to calculate the distance d between the points use the distance formula
d = √(x₂ - x₁ )² + (y₂ - y₁)²
with (x₁, y₁ ) = (- 10, - 2) and (x₂, y₂ ) = (- 4, - 2)
d =
=
=
= 6
Answer:
2
Step-by-step explanation:
The average rate of change of h(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 2, 4 ] , then
f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12
f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0
Then
average rate of change =
=
= 2
