Answer:
Explicit formula: y=3x+11
How tall will the plant be after 6 months? 29 inches
Step-by-step explanation:
Since it grows 3 inches per month, the slope would be 3, and since Gianna planted it when it was 11 inches already, the y-intercept would be 11.
plug in 6 for x (for 6 months): 3(6)+11=29
Answer:
What is 20 percent of 500.? = 100.
Step-by-step explanation:
From the text you can derive the following equations:
(1) A = bh/2 = 8
(2) and h = b+6
Fill in h in (1):
b(b+6)/2 = 8 => b^2 + 6b = 16 with the quadratic formula or simply trying some values for b you can find b=2, so h=8.
Answer:
C 18x + 8
D 2(9x + 4)
F 6(3x + 2) – 4

Answer:
The bench was $375 and the garden table was $284.
Step-by-step explanation:
Let x be the value of the bench, if the table is 91 less than the value of the bench then the equation can be:
x + x-91 = 659
2x -91 = 659
Add 91 to both sides of the equation to isolate the 2x:
2x - 91 + 91 = 659 + 91
2x = 750
Divide both sides by 2 to get 1x:
2x ÷ 2 = 750 ÷ 2
x = 375
This means the bench was $375 and the garden table was $284.
Hope this helps!
