Answer:
7 days
Step-by-step explanation:
Bamboo plant A = 1.2 + 0.45d
Bamboo plant B = 0.85 + 0.5d
Where,
d = number of days
Equate the two growth
Bamboo plant A = Bamboo plant B
1.2 + 0.45d = 0.85 + 0.5d
Collect like terms
1.2 - 0.85 = 0.5d - 0.45d
0.35 = 0.05d
Divide both sides by 0.05
d = 0.35 / 0.05
d = 7 days
Plant B be taller than Plant A after 7 days
Ratio x coordinates = 20/10
ratio y coordinates = 10/5
here’s a picture incase :)
P1=2.5+2.5+4.75+4.75=14.5 cm
0.5 cm - 1 in
2.5 cm - 5 in
4.75 cm - 9.5 in
P2=5+5+9.5+9.5=29 in
The answer to your math problem is
8x + y= 39
The slope would be the negative reciprocal = -3/4
plug in (-4,-1) for x and y to find b.
y = mx+b
-1 = (-3/4)(-4) + b
-1 = 3 + b
-4 = b
THE ANSWER
y = -3/4x -4
