Answer: Choice C

To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)

============================================

Explanation:

The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.

The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,

slope = rise/run = (change in y)/(change in x)

Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

Alex787 [66]

Answer:

It will take 5 hours and 5 minutes to fill the tank

Step-by-step explanation:

Here, we want to get the time taken to fill the tap

Let us have the rate per hour

A fills in 6 hours; so the fraction filled in an hour is 1/6

B fills in 8 hours, so the fraction filled in an hour is 1/8

C empties in 10 hours, so the fraction removed per hour is 1/10

So factoring the supply and removal, where removal is on a negative basis

we have it that in an hour, the fraction retained is;

1/6 + 1/8 - 1/10

= (20 + 15 - 12)/120

= 23/120

So this is the fraction retained per hour

The number of hours it will take to have a whole is simply the reciprocal of this fraction

That would simply be 120/23 = 5 5/23

5 hours and 5 minutes

The transformation T = [0 1 -1 0] is applied the figure below.

Margaret [11]

Answer:

<h2>a.) reflect across x-axis</h2>

Step-by-step explanation:

The transformation described is about multiplying the vertical value by -1:

$(x,y) \implies (x,-y)$

That means all vertical coordinates will change to the opposite side, but all horizontal coordinates will maintain at the same coordinate.

As a result, we'll have a reflection across the x-axis, because the y coordinates were transformed.

Therefore, the right answer is A.

The gray area is the sidewalk. the area of the sidewalk is ___________ square units.

Bas_tet [7]

The area of the sidewalk is 72 square units. Solution: First, multiply 10 by 12 which equals 120. Then, subtract 6x8=48. So, therefore, 120-48= 72
