The sum of 8 and 7= 8+7=15
and to double it you just do 15*2 and that = 30.

Answer:

C

Step-by-step explanation:

Given the 2 equations

3x + 4y = 8 → (1)

y - 5x = 2 ← rewrite as

- 5x + y = 2 → (2)

Multiplying (2) by - 4 and adding to (1) will eliminate the y- term

20x - 4y = - 8 → (3)

Add (1) and (3) term by term to eliminate y

23x + 0 = 0

23x = 0 , then

x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (1)

3(0) + 4y = 8

4y = 8 ( divide both sides by 4 )

y = 2

solution is (0, 2 )

That is the lines intersect once at (0, 2 )

Shen started to run on a treadmill after setting its timer for 93 minutes. The display says that he has finished 69% of his run.
djverab [1.8K]

Answer:

64.2 minutes

Step-by-step explanation:

We are given that

Shen set timer to run=93 minutes

He has finished his run=69%

We have to find total number of minutes have gone by.

69% of 93

=\frac{69}{100}\times 93

By using

a%=\frac{a}{100}

69% of 93=\frac{6417}{100}

69% of 93=64.17 min

69% of 93\approx 64.2min

Hence, 64.2 minutes have gone by.

Write an equation that can be used to find 푚∠푀. Then, solve it. Round to the nearest degree.
jek_recluse [69]

Answer:

M = 27 degrees

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin M = opp side/ hypotenuse

Sin M = 5/11

Take the inverse sin of each side

sin ^-1  sin M = sin ^1 (5/11)

M = 27.03569179

To the nearest degree

M = 27 degrees

AysviL [449]

Answer:

y=-\frac{4}{3}x+2

Step-by-step explanation:

To write the equation for this line, we are going to use slope-intercept form, which is written as

y=mx+b.

Here are the meanings of each variable:

y= basically the "name" of the function and it always stays as y.

m= slope, which is rise over run.

x= variable that is always on the right of the slope and it always stays as x.

b= y-intercept, or the value that crosses the y-axis.

We will substitute numbers into the equation along the way. The first thing we will want to do is find b, which is the easiest.

The line crosses the y-axis at 2, so that is our value of b.

Our new equation is

y=mx+2.

Next, we will find the slope. The most efficient way of doing this is looking at the lowest point that is already provided, (3, -2), and finding a way to rise and run to the highest point, (0, 2).

If you look closely at the graph, we need to rise up 4 and run over -3 to get to the other point. Therefore, the slope is -\frac{4}{3}, and we can substitute it into our equation, which is completed and is now

y=-\frac{4}{3}x+2

I hope this helps you out!! Have an awesome day ^^
