Answer:
d. x = -3
Step-by-step explanation:
<u />
÷ (x+8)(x-2) = 0
f(x) / g(x) = 0
Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).
<u />
= 0 ------ square both sides
x + 3 = 0
solve for x:
x = -3
Hello there!
(-1)^3 * (-1)^2
Use the distributive property
= (-1)(-1)(-1)* (-1)(-1)
= (-1)^5
= -1
I hope this helps!
Answer:
x = 
Step-by-step explanation:
Given
kx - c = 9 ( add c to both sides )
kx = 9 + c ( isolate x by dividing both sides by k )
x = 
Answer:
40 mpg
Step-by-step explanation:
To find the unit rate which is 1/8 we just divide 15 by 3 which is 5 and to find the mpg of the full gallon now that we have the unit rate we just multiply the 1/8 or 5 miles by 8 which would give us 8/8 or 40 miles.
use cross products
(3r+6) *2 = 9*(2r-4)
6r+12 = 18r-36 distribute
12 = 12 r -36 subtract 6r from each side
48 = 12r add 36 to each side
4=r divide by 12
