Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2
Answer:
9.9 gallons
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.


Now, lets put the values above back into the equation:

Lets solve this equation. First we divide 2,475 by 250, making x by itself.


This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.
Fill in the slope and that point in y=mx+b
-14=6(-12) + b
-14= -72 + b
b= 58
Y=6x + 58
Answer:
See description below.
Step-by-step explanation:
To choose the correct equation, find the slope of the line on the graph. Identify two points on the line. Then subtract to find their rate of change using the slope formula.

When you know the slope, find the negative reciprocal. For example, if the slope is 2/1 then the negative reciprocal is -1/2. This is the slope of a perpendicular line to a line with slope 2. Choose the equation which has this same slope.
Example:
y = 2x -1
y= -1/2 +5
