Hey there Rosy! I did this recently and the answer is:
1 : 4
2 to 8
18
---
72
So below m in the chart, is shows what m equals for you to substitute in the equation
So the second blank would be 42.
Since 7*6=42.
The third blank would equal to 56.
Since 7*8=56
Answer:
a.
500x+0.04=y
400x+0.05=y
for percentages move decimal to the left twice
Answer:
y=1/3x -4
Step-by-step explanation:
3y-x=-12
y= 1/3x-4
m=1/3
(gradient is the same since its parallel)
y=mX+c
(2) = 1/3(18) + c
2 = 6 + c
2 - 6 = c
c= -4
(y-intercept)
Therefore: y=1/3x-4
Answer:
y = - 4x - 8
Step-by-step explanation:
From the graph we get :
slope = (-8)/2 = -4
y-intercept = -8
