Answer:
a.-3
b. y=-3x-1
c. y=-3x-1
d. 3x+y=-1
Step-by-step explanation:
Answer: If you mean five instead of time, then the answer would be 82.5
Step-by-step explanation:
15 × 5.5 = 82.5
Let's call the unknown number x.
x+ (50% of x) = 135
x + (0.5x) = 135
1.5x = 135
x = 135/1.5
x = 90
Therefore, the number is 90
Answer:
B. y=1/2x+7
Step-by-step explanation:
y2-y1/x2-x1 this finds the slope
Then take one of the coordinates: either (2,8) or (4,9) and plug them into x and y to find b (the y-int)
