-7(n+3)-8(1+8n) pls help

To solve this problem I'd reccomend first finding the area of the circle, then dividing that area by 4 to find the area of the shaded area.

Let's begin!

To find the area of a circle, we will use this formula:

A = (pi) r^2

(pi multiplied by the radius squared)

The radius of a circle is the distance from the center outwards. The diameter goes straight across the circle, through the circle. Radius is basically half of a circle's diameter.

The math problem states that we approximate pi to be 22/7, so we will use that in place of the pi symbol.

Finding the area of the circle:

(pi) r^2 = A

(Write out formula)

(22/7) 12^2 = ?

(Input the values that we now, r equals 12 because that is the radius shown on the image the problem provided.)

22/7 × 144 =

(Start solving, we did 12^2 first)

452 4/7 in^2 (inches squared or square inches)

(Always use your units, math teachers usually don't allow naked numbers. You'll notice that our answer is in fraction form, that's okay if it is, unless your teacher says otherwise, because some teachers prefer answers in decimal form rather than in fraction form)

Now that we know the whole area of the circle, we can finally find the area of the shaded region :)

452 4/7 ÷ 4 = 113 1/7 in^2 (square inches or inches squared)

The area of the shaded region is 113 1/7 in^2

(Hope this helps :) )

Answer:

x=7

Step-by-step explanation:

make y = 0 to find x intercept

(x intercept is where the line touches the x axis, and y has to be 0 for that to happen)

y=2x-14

0=2x-14

14=2x

7=x

Answer:

x=7/5 or 1.4

Step-by-step explanation:

5x+17=24

you would subtract 17 from both sides.

5x=7

Then you would divide 5 from both sides

x=7/5 or 1.4

Answer: x=1.4

Step-by-step explanation: You need to get x alone, in order to do this, you will first need to subtract 17 from 24, then one you have that answer divide it by 5. To expand on this, because 17 is being added on the left side you now need to subtract 17 from both sides in order to get rid of it. After that you will only have left 5x=7. Because 5 and x are being multiplied you need to divide 5 from both sides. That will leave x alone on one side and 1.4 on the other. So x=1/4

24-17=7

7/5=1.4

x=1.4

I hope this made sense and that it helped you.

Answer:

5,11,7

Step-by-step explanation:

Hey there!

The answer to your question is x = 45

To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.

15(3) = 1/3x(3)

45 = x

Hope this helps and if you need any further help, I would be happy to!

What's happening in the real world?

As he cooks on the barbecue, the weight of the tank goes down  because some of the propane is getting used up.

Given that is happening, the graph showing that has to start with a lot in it and slowly decrease.

A shows the exact opposite. As he cooks, he gets more weight in the tank, not less.

B says that over time, there is no change in weight of the tank. How can that be? The tank ought to get lighter. The answer is not B

C is the correct answer.

Best Line of Fit

Algebra II

Step-by-step explanation:

We can graph the scatter plot and estimate a best line of fit by drawing it in (See Attachment). We can also get the best best of line of fit using your calculator's graphing capacities. The black line is our estimated best line of fit and the red line is the linear regression.

Step 1: Define

Find 2 points from the chart.

Point (1, 2)

Point (7, 7)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Step 3: Find Equation

We can roughly estimate the y-intercept of the best line of fit. We see that it is (0, 1.5)

Our equation would then be:

The point that could be on the line that Chung-Li drew is; Option C; (2, 3)

We are given a table showing and we are told that a graph was drawn from the table with slices of strawberry as the x-coordinate and the number of slices of banana as the y-coordinate.

Now, since we know what is on x and y coordinates, it means that any point that will be on the drawn line will have the same slope as the given points.

Let's get the slope for each point;

Point 1; 4, 6

Slope of point 1 = y/x = 6/4 = 3/2

Point 2; 8, 12

Slope of point 2 = y/x = 12/8 = 3/2

Point 3; 12, 18

Slope of point 3 = y/x = 18/12 = 3/2

Point 4; 16, 24

Slope of point 4 = y/x = 24/16 = 3/2

We can see that the slope of each point is 3/2 and so the only option that will have it's point on the line must be one with a coordinate of (2, 3) which is option C.

Answer:

Terms: 6x², 6x, -4x, -16

Equivalent terms: 6x, -4x

Coefficients: 6 (twice), -4

Constants: 16

Explanation:

A term in an expression is a quantity in that expression. It may include a variable, but it doesn't have to! There are 4 terms in this expression: 6x², 6x, -4x, -16. Remember to put the negative sign in front if the term follows a minus sign.

Equivalent terms have the same variable level. Here, the equivalent terms are 6x and 4x, because they both have x as their variable.

Coefficients appear in front of a variable in a term. There are 3: 6, another 6, and -4.

Constants don't have a variable. There is just one: -16.
