Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
Solution:
a=-2 b=1 c=4 d=0
Analysis:
When we multiply a matrix by a constant, we multiply each term of the matrix by the constant.
In this case, as we need to find the value of the initial matrix, we can divide each term of the matrix by the constant. In this case, let´s divide by -5
So, it would be:
a=10/-5 a=-2
b=-5/-5 b=1
c=-20/-5 c=4
d=0/-5 d=0
You know that the y is negative and the x is positive (it's the lower right side of a graph)
