Step-by-step explanation:
Given
f(x) = -5x - 1
and
g(x) = 2x + 2
Now
f(3) = - 5 * 3 - 1
= -15 -1
= -16
Also
g(-4) = 2 * (-4) + 2
= - 8 + 2
= - 6
Answer:
-3/2
Step-by-step explanation:
Remeber, to find slope we use this formula:
y - y all over x - x, or (y-y) / (x-x)
(6-9) / (5-3)
-3 / 2
= -3/2
Answer:
7p(p-1)
Step-by-step explanation:
7p²-7p=7p(p-1)
The price:
- last year: $2.25
- this year: $.45
The decrease: $2.25 - $.45 = $1.80
2.25 : 1.80 = 100 : x
2.25 x = 180
x = 180 : 2.25
x = 80
Answer:
The percent of decrease is A ) 80%
Answer:
2x^2 - x - 15 = 0.
Step-by-step explanation:
In factor form this is
(x + 5/2)(x - 3) = 0
x^2 + 5/2x - 3x - 15/2 = 0
x^2 - 1/2x - 15/2 = 0
Multiply through by 2:
2x^2 - x - 15 = 0.
