Answer:
The slope is 1/2 and the y intercept is 7/4
Step-by-step explanation:
2x-4y+7=0
To find the slope, we need to put the equation in slope intercept form
y = mx+b
So we need to solve for y
Subtract 2x from each side
2x-2x-4y+7=0-2x
-4y +7 = -2x
Subtract -7
-4y+7-7 = -2x-7
-4y = -2x-7
Divide by -4
-4y/-4 = -2x/-4 -7/-4
y = 1/2 x +7/4
The slope is 1/2 and the y intercept is 7/4
476.00×5%=23.80 tax=476+23.80=499.80
499.80×15%=74.97
499.80+74.97=574.77
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
Answer:
Step-by-step explanation:
<u>The function in vertex form:</u>
<u>x- intercepts are 15 and 35:</u>
- 0 = a(15 - 25)² + 32 or 0 = a(35 - 25)² + 32
- 0 = a*100 + 32
- 100a = - 32
- a = -32/100
- a = -8/25 or -0.32
