Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $200 a month and an additional $12 for

Alina [70]

200+12m= 644
subtract 200 from both sides
12m= 444
divide both sides by 12
m= 37

Mila graphs the point A

melamori03 [73]

Answers:
B. <span>The x-coordinate of point A is 5.
</span>E. <span>Point A is on the x-axis.
</span>
Explanation:
Any point drawn on the coordinates has the general notation of (x,y).
The given point is (5,0). This means that:
The x-coordinate of the point is 5
The y-coordinate of the point is 0

Now, let's check the place of this point.
The x-coordinate of the point is 5. This means that we will move 5 points to the right of the origin on the x-axis
The y-coordinate of the point is 0. This means that we will not move along the y-axis which means that the point stays on the x-axis.

Now, comparing the deduced results with the given choices, we will find that the correct choices are B and E

Hope this helps :)

So we want to find the surface area of this pyramid. Finding the surface area of a 3D shape is essentially finding the area of all its sides and adding them together.

What we're going to have to do here is find the area of the base of the pyramid, which is basically a square, and find the area of all four sides of the pyramid, which are triangles.

Formula for area of a square: length × width

Formula for area of a triangle: (base × height) ÷ 2

First we will find the area of the base:

l × w = A

(Write out formula)

8 × 8 =

(Input values)

A = 64 m^2 (square meters or meters squared)

(We have our answer, dont forgot to write your units.)

So we've figured out the area of the base. Now onto the triangles:

(b×h) ÷ 2 = A

(Write out formula)

(8 × 6) ÷ 2 =

(Input values)

48 ÷ 2 =

(Use PEMDAS to solve this correctly. We did whatever was in the parenthesis first, which was multiplication.)

A = 24m^2 (square meters or meters squared)

(We have our answer.)

Now we've found the area of the base of the pyramid and one of the sides of the pyramid, but we're almost done! There's four sides to the pyramid, they're all the same. So since we found the area for one, we can multiply that by 4 to find the area of all sides added together:

24 × 4

(area of a side × total sides)

= 96m^2

All that's left is adding the 96 to the area of the base to get our total surface area of the pyramid:

96 + 64 = 160

The surface area of the pyramid is 160m^2(square meters or meters squared)

(Hope this helps :) )

Systems of Linear Equations What are the different ways to solve a system of linear equations? When do you get an answer to a sy

Mrac [35]

Answer:

Different ways to solve a system of linear equations:

isolate one variable in one equation and replace it in the other equation
multiply/divide one equation by a constant and then add/subtract it to the other one, so that only one variable remains
graph the equation and look at the intersection point

If you graph the system:

there is only one solution if the lines intersects at only one point
there is no solution if the lines don't intersect each other (they are parallel)
there are infinitely many solutions if the lines overlap each other (they are the same equation multiplied by some constant)

Step-by-step explanation:

1st system

y = -x – 7

y = 4/3 x – 7

solution: x= 0, y = 7

2nd system

y = -3x – 5

y = x + 3

solution: x = -2, y = 1

3rd system

y = -2x + 5

y = 1/3 x – 2

solution: x = 3, y = -1

4th system

3x + 2y = 2

x + 2y = -2

solution: x = 2, y = -2

5th system

x + 3y = -9

2x – y = -4

solution: x = -3, y = -2

6th system

x – 2y = 2

-x + 4y = -8

solution: x = -4, y = -3

7th system

5x + y = -2

x + y = 2

solution: x = -1, y = -3
