12 ÷ 75 = 0.16.
So she runs 0.16 miles per minute.
Hope it helps!
They can fit 24 tiles because
6 rows times 4 tiles =24 tiles
6x 4 =24
Find how much it will cost.
24 x 5 = 120
It will cost $120
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides
17 - 4x = y + 4x - 4x....combine like terms
17 - 4x = y...rearrange
y = -4x + 17 <===== slope intercept form
Y = x² + 7x - 4
y = -x - 4
x² + 7x - 4 = -x - 4
+ x + x
x² + 8x - 4 = -4
+ 4 + 4
x² + 8x = 0
x(x) + x(8) = 0
x(x + 8) = 0
x = 0 or x + 8 = 0
- 8 - 8
x = -8
y = -x - 4
y = -0 - 4
y = 0 - 4
y = -4
(x, y) = (0, -4)
or
y = -x - 4
y = -(-8) - 4
y = 8 - 4
y = 4
(x, y) = (-8, 4)
The solutions are (0, -4) and (8, -4).
