Help, How Do I Do This Problem And I Really Need This

Answers

Answer 1
Okay, so one of the geometric theorems is that two of the inside angles equals the outside angle in a situation like this one.

So, set them equal:
2x+ 2 + 4x + 8 = 8x - 30

Combine like terms:
6x + 10 = 8x - 30

40 = 2x

x = 20

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.

Answers

Answer:

(6,-7)

Step-by-step explanation:

subtract them:

-8x - 5y = -13

-4x - 5y = 11

you get

-4x = -24

so x = 6

plug x into the second equation:

-24 - 5y = 11

-5y = 35

y = -7

so your solution is (6,-7).

Answer:

Your solution is (6, -7).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-8x - 5y = -13

-4x - 5y = 11

Let's change the second equation into one with one variable on each side.

-5y = 4x + 11

y = -4/5x - 11/5

Now, plug this into your first equation.

-8x - 5(-4/5x - 11/5) = -13

Distribute the -5 sign.

-8x + 4x + 11 = -13

Combine the like terms.

-4x + 11 = -13

-4x = -24

Isolate x by dividing both sides by -4.

x = -24/-4

x = 6

Now plug this back into either equation.

y = -4/5(6) - 11/5

Multiply.

y = -24/5 - 11/5

Subtract.

y = -35/5

Simplify.

y = -7

Your solution is (6, -7).

Check this by plugging in these values into the equation you have not checked yet.

-8(6) - 5(-7) = -13

-48 + 35 = -13

-13 = -13

Your solution is correct.

Hope this helps!

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day

Answers

Answer:

26.3 grams

Step-by-step explanation:

57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

We can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

What is dilation?

Dilation is the enlargement or shrinking of the coordinates.

Given is a triangle as shown in the image.

The coordinates of the vertices of the triangle are -

C(3, 2)

B(0, 4)

A(4, 4)

For the dilation by a scale factor of {K} = 3, we can write -

C'(3 x 3, 2 x 3) = C'(9, 6)

B'(0 x 3, 4 x 3) = B'(0, 12)

A'(4 x 3, 4 x 3) = A'(12, 12)

Therefore, we can write the coordinates of the vertices of the triangle after dilation by a scale factor as -

C'(9, 6)

B'(0, 12)

A'(12, 12)

Step-by-step explanation:

1.

Zero's

x = -3i, x = 2 and the third zero is x = 3i

Polynomial is:

(x + 3i)(x - 3i)(x - 2) =(x² - 9i²)(x - 2) =(x² + 9)(x - 2) =x³ - 2x² + 9x - 18
