Answer:
x = -10
Step-by-step explanation:
10 + 7x = - 60
- 10 = - 10
7x = -70
x = -10
Answer:
96
Step-by-step explanation:
6.4 miles per day
x miles per 15 days
cross multiply and get the answer of 96
The slope of a line is simply a ratio of the change in y-value to the change in x-value
Change in y = y₂ - y₁
= 12 - (-6) = 18
Change in x = x₂ - x₁
= 6 - 3 = 3
Ratio of change in y to change in x = 18/3 = 6
The slope is 6
Answer:
9
Step-by-step explanation:
the slope of this equation is 9. he ears $200 say for a bonus or something. but his hourly rate is 9, if he works 10 hours, he ears $90 plus that 200
Answer:
22x^2 -10xy + 12x
Step-by-step explanation:
To add and subtract polynomials, combine only like terms. When doing it vertically, stack polynomials and line up the same bases and exponents. Once this is done, simply add and subtract the coefficients.
10x^2 + 12xy + 4x
+ 12x^2 -22xy + 8x
_________________
22x^2 -10xy + 12x
Here we added 10 + 12 = 22, 12 + -22 = -10 and 4 + 8 = 12.
