Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
Answer:
A linear inequality graph usually uses a borderline to divide the coordinate plane into two regions. One part of the region consists of all solutions to inequality. The borderline is drawn with a dashed line representing '>' and '<' and a solid line representing '≥' and '≤'.
Answer:
B. One constant would be positive and the other constant would be negative.
Step-by-step explanation:
This answer is correct because you have to look at the -84. The factors of -84 that work are -12 and 7. This means that one constant is positive and the other is negative.

Answer: A) 1/10</h3>
=============================================
Work Shown:
(4/5) divided by 8
(4/5) divided by (8/1)
(4/5) * (1/8) .... flip the second fraction and multiply
(4*1)/(5*8)
(4*1)/(5*4*2)
1/(5*2) ... the '4's cancel
1/10
--------------
Alternative method:
4/5 = 0.8 when using a calculator or long division
(4/5) divided by 8 = 0.8/8 = 0.1
0.1 = 1/10
The digit 1 in 0.1 is in the tenths place, so that's why 0.1 = 1/10
Or you could use your calculator to see that 1/10 = 0.1
Another idea is to do
0.1 = 0.1/1 = 0.1/1.0 = 1.0/10.0 = 1/10
here I moved the decimal point 2 spots to the right for the numerator and denominator.
