Answer:
D
Step-by-step explanation:
You can put the points in as the x and y values. 12(2)-(-1)=25 and 9(2)+(-1)=17
Answer:
The y-value is -20
Step-by-step explanation:
So let's solve this by Elimination method;
-2(4x + 5y = -12)
4(2x + 3y = -16)
Let's Distribute;
-8x - 10y = 24
8x + 12y = -64
So x cancels out because -8 + 8 = 0
-10y + 12y = 2y
24 - 64 = -40
2y = -40
Divide both sides by 2;
y = -20
Now lets plug in y to find the value of x;
4x + 5(-20) = -12
4x - 100 = -12
Add 100 to both sides;
4x = 88
Divide both sides by 4;
x = 22

Divide the pages read by the portion read:
60/ 3/4 = 60 x 4/3 = 240/3 = 80
