5 + 2(0) =

5 + 0 =

5

Answer:

Yes. (see below)

Step-by-step explanation:

First, find the slope of the line. You can do that by using the slope formula:

      y2 - y1

m = ----------

      x2 - x1

Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).

      4 - 3

m = ------

      2 - 0

      1

m = --- = 1/2

      2

Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.

The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.

Now, plug them in:

y = mx + b

y = 1/2x + 3

To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:

13 = 1/2 (20) + 3

13 = 10 + 3

13 = 13

This is true, so the point (20, 13) is on this line.

Answer:

if you need distance then

Step-by-step explanation:

speed = distance /time

so

135=x/8

135x8=x

1080=x = distance

Answer:

4.2 miles

Step-by-step explanation:

6 miles/50 minutes = x miles/35 minutes

1. Since 5 is the GCF (greatest common factor) of x and 35, that is what the ratio must first be converted into, by dividing by 10: 6/50 = 0.6/5

2. To convert this to 35 minutes, it must be multiplied by 7, because 5 * 7 = 35. This leaves us with the answer:

0.6/5 = 4.2 miles/35 minutes

Answer:

1725 ft^2

Step-by-step explanation:

[tex]\frac{b_{1} + b_{2}}{2} (h) = \frac{65 + 50}{2} (30) = \frac{115}{2} (30) = 57.5(30) = 1725[/tex]

Answer:

(x, y) = (2, 19)

Step-by-step explanation:

7x + 5=x + 17

x=2

y=7*2+5

y=19

Please give brainlyist

Answer: (2, 19)

Step-by-step explanation:

There are three general ways to solve a system of equations:

- Substitution

- Elimination

- Augmented Matric

Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.

--------------------------------------------------------------------------------------------------------

Given

y=7x+5

y=x+17

Substitute y into the equations

7x+5=x+17

Subtract 17 on both sides

7x+5-17=x+17-17

7x-12=x

Subtract 7x on both sides

7x-12-7x=x-7x

-12=-6x

Divide -6 on both sides

-12/-6=-6x/-6

x=2

Substitute  value into one of the equations

y=x+17

y=2+17

y=19

(2, 19)

Answer: The correct answer is D

Step-by-step explanation:

Answer:

4π

Step-by-step explanation:

180 * 4 * π/180 radians

180s cancel out

4π radians

Answer:

D

Step-by-step explanation:

To solve this you can just plug in the x values into the equation and if the answer is correct the y value should be your answer

For example if we look at D

we can plug in 2 for y=5x and get 10

We can see that the y value in the ordered pair is also 10 making this the correct answer

kind of hard to explain if you have any questions leave a comment

Answer:

D

Step-by-step explanation:

y= 5x

10= 5(2)

You just have to add like values together.

Answer:

There would be a y-intercept of one and a slope of -3/4.

Step-by-step explanation:

Negative slope means it will increase going left.

3/4 is the slope 3 rise/ 4 run

the y intercept is 1, so the line will cross the y axis at the 1 point.

Answer:The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.

Answer the questions to estimate the probability that the Iceblades will win the game.

1. The paired digits 00 to 99 represent 100 shots.

Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.
