Answer:

50x2 =100

So the final box is 50x2 = 100

Step-by-step explanation:

There is a pattern in this table.  5, 2, and 2.  Ex. 2x5=10, 10x2 =20 on top

The pattern is the same on the bottom: 5x5 =25, 25x2=50, and 50x2 =100

So the final box is 50x2 = 100

Set up a proportion. 2/5 = x/40
to solve the equation first cross multiply.
x*5=40*2
x*5=80
now divide both sides by 5, 80 divided by 5 is equal to 16.
so the number of girls in the computer lab is 16.

Answer:

y = \frac{-3}{2}x -- 2

Step-by-step explanation

We need to fill out the formula y = mx + b.

First, we must find out what each part of that formula means.

mx = slope

b = y-intercept

y = solution (Always unknown)

We already know the slope of the formula, so we can fill that out.

y = \frac{-3}{2}x + b

If it has a slope of -3/2, then that means it is moving down 3 points and moving  to the right 2 points to find the next line. because rise over run.

If it passes through the point (-4, 4) then from their subtract 3 to 4, and 2 to -4.

This means the next point it will reach is (-2, 1). Once again, subtract 3 from 1, and add 2 to -2.

The next point it will reach is (0, -2) This gives us the y-intercept of the equation.

Now we can fill out the rest of the formula!

y = \frac{-3}{2}x -- 2

0 − 4 = − 4

4 = − 4

2 = − 4

Step-by-step explanation:

Find the equation with a point and y-intercept.

y = ( y/ x  −  y )  x  +  x y

The chosen topic is not meant for use with this type of problem. Try the examples below.

1. Is triangle P’Q’R larger or smaller than triangle PQR? Explain how you know
Salsk061 [2.6K]

Answer:

The length of the line is PQ as this line is parallel to the x - axis. So, the length of the line is the summation of 10 from second quadrant and 20 from first quadrant. So, the sum is 30. Hence the length of the line is 30 units.

Step-by-step explanation:

The length of a line segment can be measured by measuring the distance between its two endpoints. It is the path between the two points with a definite length that can be measured. Explanation: On a graph, the length of a line segment can be found by using the distance formula between its endpoints.
