Hello.

2 (12x-11) = -4 (1-6x)

24x-22 = -4 + 24x

0 = 18

Undefined would be your answer. Be sure to double check.

Hope that helps.

xxMikexx [17]

Some landforms made by erosions are:

Caves, bays, and arches.

Some landforms made by deposition include:

beaches, deltas, and sand dunes.

Erosion is caused by weathering, (for example rain) and deposition is caused by sediments or rocks transported by flowing water or ice.

HELP ME DO THIS PLZ

cestrela7 [59]

Answer:

It landed at a height of 14 feet

Step-by-step explanation:

Given

$y = -\frac{1}{8}x^2 +4x$ --- Path of a t-shirt

$3y = 2x - 14$ --- height of bleachers

Required

Height when t-shirts land in bleachers

$3y = 2x - 14$

Make y the subject

$y = \frac{2}{3}x - \frac{14}{3}$

Substitute $y = \frac{2}{3}x - \frac{14}{3}$ in $y = -\frac{1}{8}x^2 +4x$

$\frac{2}{3}x - \frac{14}{3} = -\frac{1}{8}x^2 +4x$

Multiply through by 24

$16x- 112 = -3x^2 +96x$

Express as:

$3x^2 + 16x -96x- 112 = 0$

$3x^2 -80x- 112 = 0$

Using a calculator:

$x = 28$ or $x = -\frac{4}{3}$

x can not be negative:

So:

$x = 28$

Substitute $x = 28$ in $y = -\frac{1}{8}x^2 +4x$ to calculate the height it landed

$y = -\frac{1}{8} * 28^2 + 4 * 28$

$y = 14$

In Triangle MNP, the measure of angle M is 24 degrees. The Measure of angle N is five times the Measure of angle P. Find Measure

Oliga [24]

Answer:

<P = 26 degrees

<N = 130 degrees

Step-by-step explanation:

The sum of angle of a triangle is 180, hence

<M + <N + <P = 180

If the Measure of angle N is five times the Measure of angle P, then;

<N = 5<P

<M = 24 degrees

Substotute into the formula

24 + 5<P + <P = 180

24 + 6<P = 180

6<P = 180-24

6<P = 156

<P = 156/6

<P = 26 degrees

Since <N = 5<P

<N = 5(26)

<N = 130 degrees

Hence the measure of <P is 26 degrees and that of <N is 130 degrees
