Answer:
C. -2
Step-by-step explanation:
Slope Formula:
Simply use 2 xy values and plug them into the formula:
m = (-4 - 0)/(5 - 3)
m = -4/2
m = -2
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be: and twice this sum would be:
Thus, "twice the sum of y and 9" is:
Answer:
Step-by-step explanation:
Take the value for b, divide it by 2 and square it to get the value for c.
In this case, b = -10.
- 10 ÷ 2 = -5
-5^2 = 25
So x^2 - 10x +25 is your quadratic equation which is equal to
