Answer:

see the explanation

The graph in the attached figure

Step-by-step explanation:

we have

$y=x+7$

This is the equation of a line in slope intercept form

$y=mx+b$

$m=1\\b=7$

therefore

The slope is positive

The y-intercept is the point (0,7)---> (value of x when the value of y is equal to zero)

The x-intercept is the point (-7,0) ---> (value of y when the value of x is equal to zero)

To graph the line plot the intercepts and join the points

see the attached figure

Use the triangle shown to find m∠Q and m∠S.

Elodia [21]

<h2><u>Hope this helps :)</u></h2>

Step-by-step Example 1:

Two angles are supplementary. If the measure of the angle is twice the measure of the other, find the measure of each angle.

Let the measure of one of the supplementary angles be a .

Measure of the other angle is 2 times a .

So, measure of the other angle is 2a .

If the sum of the measures of two angles is 180° , then the angles are supplementary.

So, a+2a=180°

Simplify.

3a=180°

To isolate a , divide both sides of the equation by 3 .

3a3=180°3 a=60°

The measure of the second angle is,

2a=2×60° =120°

So, the measures of the two supplementary angles are 60° and 120° .

Step-by-step Example 2:

Find m∠P and m∠Q if ∠P and ∠Q are supplementary, m∠P=2x+15 , and m∠Q=5x−38 .

The sum of the measures of two supplementary angles is 180° .

So, m∠P+m∠Q=180°

Substitute 2x+15 for m∠P and 5x−38 for m∠Q .

2x+15+5x−38=180°

Combine the like terms. We get:

7x−23=180°

Add 23 to both the sides. We get:

7x=203°

Divide both the sides by 7 .

7x7=203°7

Simplify.

x=29°

To find m∠P , substitute 29 for x in 2x+15 .

2(29)+15=58+15

Simplify.

58+15=73

So, m∠P=73° .

To find m∠Q , substitute 29 for x in 5x−38 .

5(29)−38=145−38

Simplify.

145−38=107

So, m∠Q=107° .

Simultaneous equation<br><br> 3x+y=16<br><br> What's the answer?

Elanso [62]

Easy
3x + y = 16
Substract -y both sides
3x = -y + 16
Now divide both sides by 3
Answer is x= -1/3 + 16/3

Answer:

1 . 16

2 . 4

3 . 64

4 . -4

The fourth one goes first and then the second one and then the first one and then the third one.

8x-1<15<br> NO one will help plss someone hellpppp

romanna [79]

Answer:

x < 2

Step-by-step explanation:

8x -1 < 15

8x -1 (+ 1) < 15 (+ 1)

8x < 16

$\frac{8x}{8} < \frac{16}{8}$

x < 2
