We know that the slope formula is m = (y1 - y2)/(x1 - x2)
Your points are: (3, 7) and (4, -8)
In this case,
x1 = 3
x2 = 4
y1 = 7
y2 = -8
Now, just plug in the numbers:
m = (7 - -8)/(3-4)
m = 15/-1
m = -15
Your slope is -15.

A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

       If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

        If the third piece is three times as long as the first piece, x, then the third piece is 3x.

       The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

42 = 6x

7 = x

              The first piece is 7 inches long.

Consider the following figure:
motikmotik

Answer:

angle <B = 76

Step-by-step explanation:

The measure of an exterior angle is equal to sum of two interior angles that is not adjacent to the exterior angle.

We can write the following equation with this information to find the value of angle <B

<B + 71 = 147 subtract 71 from both sides

<B = 76

Liliana wants to determine the height of an enlarged photo that she plans to frame. The original photo was 11 inches wide by 14
inn [45]

Answer: 168 inches.

Explanation:

First thing you must always do when solving word problems is read closely, and take note of any number.

In this case, the first thing we must do is find the scale factor.

For this, we use one of the dimensions. We will use the width of the photo.

We have then:

k = 132/11

k = 12

Then, we look for the value of the height of the new photo. To do this, we multiply the scale factor by the original dimension.

We have then:

14k = 14 (12) = 168

Thus, 168 inches is your answer! :)

Hope this helps! :)
