Answer:
x=9
Step-by-step explanation:
6+5x=51
-6 -6
________
0 5x=45
_ _
5 5
x=9
-8≥-5x+2>-38
-10≥-5x>-40
2≤x<8 (when divided by a negative number, the sign changes from ≥ or > to ≤ or <)
so x is between 2 (include 2, a solid dot) and 8 (doesn't include 8, a hollow bubble)
the third choice is correct.
Answer:
(x+3,y-5)
Step-by-step explanation:
they both go to the right 3 and down 5
4 would be the answer for this questions
Answer:
The first pair shows equivalent expressions.
Step-by-step explanation:
3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6
The first equation is 3(x+2)=3x+6
Therefore, the first pair shows equivalent expressions.
