Answer:
-2
Step-by-step explanation:
5x – 15 > 10 + 20x
Subtract 5x from each side
5x – 15-5x > 10 + 20x-5x
-15 > 10+15x
Subtract 10 from each side
-15-10 >15x
-25 > 15x
Divide each side by 15
-25/15 > x
-5/3 > x
X must be less than -1 2/3
The only value that is less than -1 2/3 is -2
Answer:
<h2>y = 2x+4</h2>
Step-by-step explanation:
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
Answer:
second or last
Step-by-step explanation:
Answer:
true for all x
Step-by-step explanation:
3(2x-4)=6(x-2)
Distribute
6x - 12 = 6x -12
Subtract 6x from each side
6x-12 -6x = 6x-12-6x
-12 =-12
Since this is always true, there are infinite solutions
