25. [tex]\frac{3}{4}c - \frac{1}{4}c + 3 = 7[/tex]
[tex]\frac{2}{4}c + 3 = 7[/tex] Subtract 3 on both sides
[tex]\frac{2}{4}c = 4[/tex] Multiply 4/2 on both sides to get "c" by itself
[tex](\frac{4}{2} )\frac{2}{4}c=4(\frac{4}{2})[/tex]
[tex]c = \frac{16}{2}[/tex]
c = 8
26. 5(2 - y) + y = -6 Multiply 5 into (2 - y)
10 - 5y + y = -6
10 - 4y = -6 Subtract 10 on both sides
-4y = -16 Divide -4 on both sides
y = 4
28. Use the slope formula, and plug in the points (-2 , -2) and (3, -1):
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{-1-(-2)}{3-(-2)}[/tex]
[tex]m=\frac{-1+2}{3+2}[/tex]
[tex]m=\frac{1}{5}[/tex]
Your answer is C
