Step-by-step explanation:
davis is right.
3(-3 + 5x) -1 (4 - 4x)
Simplify each term by first using the distributive property with each set of parenthesis:
3*-3 + 3*5x - 1*4 -1* -4x
Now do the multiplications:
-9 + 15x -4 + 4x
Combine like terms
15x +4x - 9 -4
19x - 13
Step-by-step explanation:
Using absolute value to tell wether the sum of two integers is positive or negative.
Suppose we have a positive integer,
x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.
For any integer x, x + (-x) = 0
Answer with Step-by-step explanation:
We are given that a function

We have to find the graph of the given function.
y-intercept:It is that value of y where the graph cut the y- axis.
Let

Substitute x=0
Then, we get

y-intercept of the graph=-15
x- intercept: It is that value of x where the graph cut the x- axis.
Substitute y=0

Substitute x=-1

Therefore,x=-1 is a solution of given equation.





Hence, the x-intercept are
-3,-1 and 5
