Answer:
15 degrees
Step-by-step explanation:
2.5x6= 15
Answer:
y = 12x + 8
Step-by-step explanation:
You can come to this conclusion by plugging in the amount of tickets bought as x in each equation, making sure the the answer y is $56 if x = 4 and $80 if x = 6
Answer:
A ( -2 , 9 )
Step-by-step explanation:
<u>Idea:</u> You find the first derivative of f(x), and then set it equal to the desired slope. You'll find some x. That we will use to find the point.
f'(x) = 3x^2 + 12x + 20
f'(x) = 8
3x^2 + 12x + 20 = 8
3x^2 + 12x + 12 = 0
3 ( x^2 + 4x + 4 ) = 0
3 ( x + 2 )^2 = 0
x + 2 = 0
x = -2
So, the desired point is:
A ( -2, f(-2) ) --> A ( -2 , 9 )
3 and 2/7 rounded is 3 and 3 times 3 is 9 and that's greater than 3 and 2/7.
Answer:
(3x-2y=-2)×3
(4x-3y=-4)×2
then minus
x=2
then for y take one equation
3x-2y=-2
6-2y=-2
y=4
