Answer:
11.) y-int:(0,1); x-int:(1,0)
12.) y-int:(0,8); x-int:(4,0)
13.) y-int:(0,-9); x-int:(-3,0)
14.) y-int:(0,-5); x-int:(-2.5,0)
Step-by-step explanation:
For each equation, first you have to graph it. Then to find the y-intercept, you mark and check where your line of your equation intersects the y-axis. To find the x-intercept, you mark and check where the line of your equation intersects the x-axis. The y-intercept always will have the coordinates of x=0 and the x-intercept always will have the coordinates of y=0.
It doesn't have to be called width
So just use the formula.
A=h×w
A=2×8.5
A=17
The area of the rectangle is 17 meters
Answer:
it is 2.83
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
<u><em>A = Area of First Rectangle </em></u>
<u><em>B = Area of Second Rectangle </em></u>
<u><em>w = Width</em></u>
<u></u>
12(w)=320+B (1st Equation)
8(w) = B (2nd Equation)
w=B/8 <em><u>(Plug this value of w into the first equation)</u></em>
12B/8 = 320 +B <u><em>(you get this)</em></u>
12B= 2560 + 8B <u><em>(Simplify)</em></u>
4B = 2560
B =640 <em><u>plug this value into the 2nd equation</u></em>
8(w) = 640
w = 80
<em>To Test This</em>
12x80 = 960
8x80 = 640
<h3>960 - 640 = 320
<u><em>Therefore the answer is correct the width is 80</em></u></h3>
