Find the area of trapezoid ABCD.

At what point does the graph of y=9x(x is exponent) cross the y-axis?

uysha [10]

Answer:

-The graph crosses the y-axis at the point (0,0)

None of the given options is correct

A graph crosses the y-axis at the point (0,y).This means that the graph will cross the y-axis when x-=0

To find the point where the graph crosses the y-axis,substitute x=0 into the given equation y-9x

substitute x=0 into the equation y-9x to find the corresponding value of y

That is,

y=9(0)

y=0

therefore the graph crosses the y-axis at the point (0,0)

Answer:

D. 220.16 Square feet

Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is $A=\pi r^{2}$ . So we fill in this equation with the information we already know:

$A=\pi 16^{2}$

$A=3.14*16^{2}$ Simplify the exponents

$A=3.14*256$ Multiply

$A=803.84$

So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple $32*32$ which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.

1024-803.94= 220.16 square feet

Answer:

B: y = -2/3x - 10/3

Step-by-step explanation:

The point is at (-2,-2), therefore when you input -2 into the desired equation, it should yield -2 as our output. If we use the equation B, the equation becomes

-4/3 - 10/3 which is -6/3. After dividing it we get -2 as the output.

To find the line yourself we use the point slope formula

y - y1 = m(x - x1)

The line is parallel to the one on the graph so the slope or m is equal to -2/3

We input the coordinates we want for y1 and x1.

y - (-2) = -2/3 (x - (-2))

y + 2 = -2/3x - 4/3

y + 6/3 = -2/3x - 4/3

y = -2/3x - 10/3
