Since both equations equal Y, set them equal to each other and solve.

3x -1 = -2x +9

Add 2x to each side:

5x - 1 = 9

Add 1 to each side:

5x = 10

Divide both sides by 5:

x = 10/5

x = 2

Now replace x with 2 and solve for y:

y = 3(2) -1 = 6-1 = 5

x = 2, y = 5 (2,5)

Can someone help geometry is confusing

NikAS [45]

<LMP and <NMP are supplementary angles so sum = 180

<LMP + <NMP = 180

(-16x + 13) + ( - 20x + 23) = 180

-16x + 13 - 20x + 23 = 180

-36x + 36 = 180

-36x = 144

x = -4

<LMP = -16x + 13 = -16(-4) + 13 = 77

<NMP = - 20x + 23 = - 20(-4) + 23 = 103

Answer

<LMP = 77°

<NMP = 103°

Answer:

2/9

Step-by-step explanation:

To determine the fraction of students that walk to school, take the fraction of students that do not ride the bus and multiply by the fraction that walk

6/15* 5/9

Simplify the fractions

6/15 Divide the top and bottom by 3

2/5

2/5 * 5/9 = 2/9

Estimate and classify the critical points for the graph of the function<br> Please show work

ikadub [295]

The critical points of the function graphed are given as follows:

x = -1.5: Local maximum.

x = -1: Local minimum.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

$f^{\prime}(x) = 0$

In a graph, they are turning points, and are classified as follows:

Local maximum, if the functions changes from increasing to decreasing.

Local minimum, if the functions changes from decreasing to increasing.

Looking at the graph, the turning points are approximately:

x = -1.5: Local maximum.

x = -1: Local minimum.

Given and which statement is correct? AB = FD AB < FD AB > FD AB ≤ FD

mojhsa [17]

Side AB is longer than side FD. Option (b) is correct.

Further explanation:

Given:

The options area as follows,

(a). $\overline {{\text{AB}}}$ and $\overline {{\text{FD}}}$ are the same length.

(b). $\overline {{\text{AB}}}$ is longer than $\overline {{\text{FD}}}.$

(c). $\overline {{\text{AB}}}$ is shorter than $\overline {{\text{FD}}}.$

(d). ${\text{AB}} \leqslant {\text{FD}}$

Explanation:

The sides opposite to equal angles are equal.

The side opposite to greater angle is greater than the other one.

The measure of $\angle {\text{DEC}}$ is ${65^ \circ }.$

The measure of $\angle {\text{BCA}}$ is ${72^ \circ }.$

$\angle {\text{BCA}}$ is greater than $\angle {\text{DEC}}$ . Therefore, the side opposite to greater angle is greater.

Side AB is longer than side FD. Option (b) is correct.

Option (a) is not correct.

Option (b) is correct.

Option (c) is not correct.

Option (d) is not correct.
