Answer:
x = -9
Step-by-step explanation:
5x + 8 - 3x = -10
Combine like terms
2x +8 = -10
Subtract 8 from each side
2x+8-8 = -10-8
2x = -18
Divide each side by 2
2x/2 = -18/2
x = -9
Answer:Of 200 people surveyed, 80 percent own a cellular phone and 45 ... If all 200 people surveyed own a cellular phone, or a pager, or both, .... Percent of those surveyed either do not own a cellular phone = 80% - 25% = 55%
Hey there!
The answer to your question is ± 12
To solve the equation x²/-10 = 2, first multiply 10 to both sides:
x² = 20
Then, take the square root from both sides:
x = ± 20
the answer would be 119.3 miles
Step-by-step explanation:
f(x) = x² - 4
y = x²-4
x = y²-4
x + 4 = y²
