(2,13),(5,22)
slope = (22 - 13) / (5 - 2) = 9/3 = 3
y = mx + b
slope(m) = 3
use either of ur points...(2,13)...x = 2 and y = 13
now sub and find b, the y int
13 = 3(2) + b
13 = 6 + b
13 - 6 = b
7 = b
so ur equation is : y = 3x + 7 <===
Answer: 150
Step-by-step explanation: So, it increases by 4% which means that some number times 1.04% equals 156. Just taking a guess, use 150. Check it. 150 times 1.04% equals 156.
Let P = the combined perimeter for the rectangle and square.
P = rectangle + triangle
P = 2(2x) + 2(x - 3) + x + x - 2 + x + 4
P = 4x + 2x - 6 + 3x - 2 + 4
P = 9x - 8 + 4
P = 9x - 4
Answer:
1. 94.25 is the surface area, 94.25 to 56.55 is the ratio of surface area to volume
2.138.23 is the surface area 138.23 to 113.1 is the ratio of surface area to volume
1.4 repeating?
3x+3=5x-10+7x
3x+3=12x-10
3=9x-10
13=9x
1.4 repeating=x
