Answer:

189

Step-by-step explanation:

If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.

We get this by taking 399 divided by 19.

So if mark travels on 9 gallons of gas and goes 21 miles per gallon, he will have traveled 189 miles.

We get this by taking 21 times 9

Answer:

your intire hw is not worth 5 pts but I will say that to find the slope is how many times the line goes up or down and to the right and left until it reaches the next dot

Step-by-step explanation:

You need to solve for x.

You can do that by either setting both of the equations equal to each other. or Solve each one separately and subtract the EG equation from the EW to get GW

Answer:

x = 40

Step-by-step explanation:

I don't understand, but I think you mean 2x + 20 = x + 60

So that's what I'm going to solve for if that's wrong tell me what you mean.

2x + 20 = x + 60 (subtract 20 on both sides)

2x = x + 40 (subtract x on both sides)

x = 40

Answer:I think it’s b too

Step-by-step explanation:

Long division is easier than you think. Here's how to solve this problem:

1. See how many times 36 can go into 66.

Multiply until you reach a number that is closest (or exact) to 66.

36 x 1 = 36; 36 x 2 = 72.

72 is over 66, so 2 doesn't work. Therefore, we'd put "1" in the first space on the shelf (right above the 6).

2. Subtract.

Now that we have "1" on the shelf, you need to subtract 36 by 66. We do this because 36 x 1 is 36. If it were the number "2" on the shelf, we'd subtract 72, and so on.

66 - 36 = 30.

3. See how many times 36 can go into 30.

Since it can't go into 30, we bring the 3 down (hence the arrow pointing down). The number is now 303.

4. See how many times 36 can go into 303.

I won't write it all out, but after multiplying 1-7 by 36, we find that the closest solution is 36 x 8 = 288.

We put "8" on the shelf, next to "1".

5. Subtract.

Now that "8" is on the shelf, we subtract 288 by 303, which gives us 15.

Since 36 cannot go into 15, and there are no more numbers we can drag down, your remainder is 15.

Your answer is:

36 R 15

The first two boxes under 663 should be filled with 36, the next three under that should have 303, the next three should have 288, and the final two boxes should have 15.

I hope this helped!

Answer:

slope, m

y-intercept

Step-by-step explanation:

When writing an equation in slope-intercept form, there will be need for slope and y- intercept.

When any equation is represented in the y = mx +c form, it is called the slope intercept form of the equation.

Here m is slope and c is constant.

To writing the slope intercept form of the equation,

There will be requirement of slope,

and y intercept, it will be in form of (0, a), here a will be value of y coordinate.

Answer:

-1

Step-by-step explanation:

Step-by-step explanation:

So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.

So we set up the equation

cos θ = adj/hype

cos θ = 5/8

θ = [tex]cos^{-1} (5/8)[/tex]

θ=51.3178125...

θ=51°

Answer:

The slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Step-by-step explanation:

Given the equation

[tex]y-4=-\frac{2}{3}\left(x-6\right)[/tex]

comparing it with the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 3/2

The point-slope form of the equation of the perpendicular line that goes through (-2, -2) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-2\right)=\frac{3}{2}\left(x-\left(-2\right)\right)[/tex]

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

writing the line equation in the slope-intercept form

[tex]y+2=\frac{3}{2}\left(x+2\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=\frac{3}{2}\left(x+2\right)-2[/tex]

[tex]y=\frac{3}{2}x+1[/tex]

Thus, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]

Here,

As the slope-intercept form is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

so

[tex]y=\frac{3}{2}x+1[/tex]

m=3/2

b = y-intercept = 1

Therefore, the slope-intercept equation is:

[tex]y=\frac{3}{2}x+1[/tex]
