How to do the vertex is using the formula -b/2a

your a=-9 and b is -18 but it going to become +18 because you are multiplying the -(-18) which there a 1 in front the neg. you going to multiply the -9 by 2 and do 18/18 so your x= -1. You got your x, you going to put in the equation as y=-9(-1)^2-18(-1)-1 then you got your y... hope this is helpful :)

Slope intercept of (1,1) and (0,7)
Sonja [21]

Answer:

\boxed {m = -6}

Step-by-step explanation:

Use the <u>Slope Formula</u> to help you determine the slope of the following two points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

(Where (x_{1}, y_{1}) is the first point and (x_{2}, y_{2}) is the second point)

-Apply both points onto that formula:

(x_{1}, y_{1}) = (1, 1)

(x_{2}, y_{2}) = (0, 7)

m = \frac{7 - 1}{0 - 1}

-Solve:

m = \frac{7 - 1}{0 - 1}

m = \frac{6}{-1}

\boxed {m = -6}

A cube measures 3 inches on all sides what is the volume of the cube in inches
Vilka [71]
Your volume would be 27 inches cubed.
This is because Volume = length x width x height. If you multiply 3 x 3 x 3 you get 27. This resulting in your answer being 27.
