Answer:
Step-by-step explanation:
90 times 3 = 270
9x-3 + 6x + 48 = 270
add like terms, 48-3 = 45
9x + 6x + 45 = 270
subtract 45 both sides and add like terms again
15x = 225
divide 15 on both sides
x = 15
8×5=40
40h-3=0
+3
40h=3
÷40
h=3/40

Answer:
1 ft./yr.
Step-by-step explanation:
When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3
1
Therefore, our rate of growth, or slope, is 1.
