Answer:
y=8x+7
Step-by-step explanation:
Use the form y=mx+b
M= the slope
B= the y-intercept
y=8x+?
Since the y coordinate of (0,7) is 7
b=7
So y=8x+7
Word Problem:
Jim is building a garden in one corner of his yard. The garden is in the shape of an equilateral triangle. If one side is 18 feet, how much fencing should he buy to enclose the garden?
Answer:
P = 18 + 18 + 18 = 54 ft
Explanation:
Equilateral triangle has all sides equal
First problem:
n/4 + 2 = -9
-2 -2
n/4 = -11
x4 x4
n = -44
Check:
-44/4 + 2 = -9
-11 + 2 = -9
-9 = -9
Second problem:
3/4x = -12
0.75x = -12
-------- ----
0.75 0.75
x = -16
3/4 * (-16) = -12 OR 0.75 * (-16) = -12
-12 = -12
Still get the same answer.
As we know,
In a triangle, the sum of lengths of two side is greater than the third side.



Answer = 15m
Answer:
477
Step-by-step explanation:
It's pretty simple. All you need to calculate is how much they made in the 9 hours. So multiply 58 x 9 and you get 522. Then take away what they didnt make, which was 45. That gives you 477.
