Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
Answer:
The price for a small glass of milk is $0.95, and the price for a breakfast taco is $1.15.
Step-by-step explanation:
Let the price of a taco be x and the price for a small glass of milk be y.
Multiply the first equation by 2:
Subtract the new third equation from the second equation:
Hence, the price for a small glass of milk is $0.95.
Substitute y into the first equation.
Therefore, the price for a breakfast taco is $1.15.

Answer:
Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be
And , because the y-intercept is at (0, R).
So, the equation of this line would be
Where we multiply the equation by
Therefore, the equation that represents this line is
