Answer:
h = 6
Step-by-step explanation:
Given he area of the banner expressed as;
A = ℎ(2ℎ−2)
h is the height of the banner
A is the area = 60
Substitute
60 = ℎ(2ℎ−2)
60 = 2h² - 2h
30 = h² - h
h²-h-30 = 0
Factorize;
h²-6h+5h-30 = 0
h(h-6)+5(h-6) = 0
(h-6)(h+5) = 0
h - 6 = 0 and h+5 = 0
h = 6 and -5
Since the height cannot be negative;
h = 6
Hence he height of the banner is 6
Answer:
Slope = 4/3
Step-by-step explanation:
Formula for slope-intercept form: y=mx + b
Given: 3y - 4x = -6
Add -4x to the right hand side to isolate out 3y (y).
It should look like this: 3y = 4x -6
Now divide both sides by 3.
You should get: y = 4/3x -2
Since it's asking for slope, your slope is 4/3.
