I really need help thank you
1 answer:
x^2 =144 has 2 solutions
x=sqrt(144)
x=+-12
x= 12 and x=-12
12*12 = 144 and (-12) * (-12) = 144
a square root has 1 positive and 1 negative solution
x^3 = 27
(x^3)^(1/3)=(27)^(1/3) ^(1/3) is the cube root
x = 3
it only has one solution because a negative * a negative * a negative would be negative

Answer:
$38.69
Step-by-step explanation:
To find the regular price, create a proportion.
To solve for the regular price x, cross multiply the numerator and denominator of each fraction.

3289=85x
38.69 = x
Answer:
f = 43/40 or 1 13/30
Step-by-step explanation:
60f=86
Divide each side by 60
60f/60=86/60
f = 86/60
Divide the top and bottom by 2
f = 43/30 or as a mixed number 1 13/30
Slope = (10 - 6)/(30 - 10) = 4/20 = 1/5
answer
1/5 is the slope
