Answer:
A.
Step-by-step explanation:
The attached graph has a y-intercept of -1 and a slope of 2, as the equation says it must.
__
The equation is in slope-intercept form, where the coefficient of x is the slope of the line. That is, the ratio of "rise" to "run" is 2: the line rises 2 grid squares for each grid square it runs to the right.
Answer:
23 mpg
161/7=23
Add in the unit you are measuring by, and you get 23 mpg
x/3=x^2/x+5
First cross multiply to get rid of the fractions.
x^2+5x=3x^2
Simplify by combining like terms.
-2x^2+5x=0
Factor out x.
x(-2x+5)=0
One of the factors must equal zero for the equation to stand.
x=0,2.5
Check for extraneous solutions by plugging in the values for x. They both work.
Answer: C
5+sqrt(4)=5+2=7
