Answer: A
Explanation:
Just use substitution because it's more efficient. Plug -2x-8 into y to make -2x-8=3x+2. Add 8 to both sides to get -2x=3x+10. Subtract 3x to both sides to get -5x=10. Divide -5 to both sides to get x=-2. Now, plug in x=-2 to one of the equations, let's use y=3x+2. The equation would be y=3(-2)+2. Multiply 3 and -2 to get -6. Add -6 to 2 and you'll result with y=-4.
Answer:
its 6
Step-by-step explanation:
divided 12 with 2 and divided 30 with 5
The person sleeps 8 hours a day.
There are 365 days in a year and 366 days in a leap year.
A leap year occurs every 4 years.
If we divide 75 by 4, we get 18.75. This number represents how many leap years occurred in 75 years. So, the person experienced approximately 19 leap years.
19 leap years has 6954 days.
The other 56 years, which have 365 days each year, have a total of 20,440 days.
That's a total of 27,394 days.
27,394 × 8 = 219,152 hours
This is approximately 24 years or 9,131 days.
F(x) = x² + 4x - 1
f(x) = x² + 4x + 4 - 4 - 1
f(x) = (x + 2)² - 5
