7.)<span> it's A because if you flip over (0,3) over the y-axis it stays at the y-axis because it is on it XD hope that wasn't too confusing lol
8.) 2/3 x +5 = 1 isolate x 2/3 x + 5 = 1 subtract 5 from both sides 2/3 x = -4 multiply both sides by 3 2x = -12 divide both sides by 2 x = -6 </span>A.) x = -6
9.) Use the given equation and plug in 11 for x y = 100 - 8.9x y = 100 - 8.9(11) y = 100 - 97.9 y = 2.1 <span>B.) 2.1%
10.) 5c + 4 = 2(c-5) multiply 5c + 4 = 2c - 10 add 10 to both sides 5c + 14 = 2c subtract 5c from both sides 14 = -3c divide both sides by -3 -4 2/3 = c A.) c = -4 2/3
</span>11.) you have to find the graph that suits the slope 2.5/1 starting at (0, 0) <span>That is Graph D
12.) The answer for this one is C.) The ordered pairs do not represent a function because one input value has two different output values.
Hope this helps
Didn't think I was gonna do them all, but here they are XD </span>
