Answer:
When x = -1/4 and when x = -15/4
Step-by-step explanation:
The x intercept will be when f(x)=0, so
0 = 4|x+2| -7
7 = 4|x+2|
|x+2|=7/4 here you have to cases
case 1
x+2=7/4
x=7/4-2
x=-1/4 = -0.25
case 2
x+2 = -7/4
x = -2-7/4
x = -15/4 = -3.75
 
        
             
        
        
        
The an answer is 2x
explanation :
12+3x-x-12
= 3x-x
= 2x
        
             
        
        
        
Answer:
It is 5,-5
Step-by-step explanation:
when you have two numbers that are the same, but one is a negative, the sum will be zero. In this case you can read it as 5-5=0
 
        
             
        
        
        
Answer:
B. 36 in.
Step-by-step explanation:
Length of the scale drawing (L) = 6.1 in.
Width of the scale drawing (W) = 1.8 in.
Actual length = 122 in.
Using the scale drawing we can apply the rules of three of proportions to find the actual width.
Thus, set the ratio of the scale drawing length to width, equal to the ratio of the actual length to width:

Cross multiply

Divide both sides by 6.1


Actual width of the rectangle = 36 in.
