Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
We have 128 ounces = 1 gallon ⇒ 1 ounce = 1/128 gallon
⇒ 8 ounces = 1/16 gallon
So 1/16 × $3.80 = $ 0.2375 ⇒ 8 ounces of milk costs $ 0.2375

Step-by-step explanation:
Step-by-step explanation:
Note that:
length of foot = y
length of forearm = x = 17
Equation: y = 0.860x + 3.302
Plug in 17 for x in the equation, and simplify. Remember to follow PEMDAS, first multiply, then combine like terms:
y = (0.860)(17) + 3.302
y = 14.62 + 3.302
y = 17.922
length of foot = y = 17.922 inches long
