D. 10
m<3 = 80 - (10) = 70
m<7 = 90 - (20) = 70
Answer: 20/3
Step-by-step explanation: 3*6=18+2=20
Since the slope is -2, then m=-2. Since the y-intercept is 5, b=5. Then, we can create the equation: y=-2x+5
Since the slope is
, then m=
. Since the y-intercept is -3, b=-3.
Then, we can create the equation: y=
x-3
1) y:10;
2) 4p+6q;
3) x +( x+ 1) = 59 => 2x = 58 => x = 29 => 29 and 30;
