Lines AB And CD (if Shown) Are Straight Lines. Find X. Give Reasons To Justify Your Solutions. PLS HELP!

Answers

Answer 1

Answer:

Step-by-step explanation:

m∠DOB = m∠DOE + m∠BOE

m∠DBO = 90 + x

m∠DOB = m∠AOC                    {Vertically opposite angles}

110 = 90 +x

x = 110 - 90 = 20

Answer 2

Answer:

x=20

Step-by-step explanation:

m∠DOB = m∠DOE + m∠BOE .        parts whole postulate

m∠DBO = 90 + x                               subs

m∠DOB = m∠AOC                    verticle angles

110 = 90 +x .                                 subs

x = 110 - 90 = 20                             alg

On Monday, Sarah has to meet her friend at the park after school The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
house?

Answers

Answer:

8x + 4 - z

Step-by-step explanation:

Given the following :

The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her

Distance from house to school = 2x + 5

Distance from school to park = z

Total distance covered = 10x + 9

Distance from park to house =?

Total distance = (distance from house to school + distance from school to park + distance from park to house)

Let p = distance from park to house

10x + 9 = (2x + 5 + z + p)

10x + 9 - 2x - 5 - z = p

8x + 4 - z

x^{2}+x-90
can you answer this please and think you.

Answers

If this is just factoring, x^2 + x - 90 turns into this:
(x - 9)(x + 10)


If your trying to solve for x, we take the factored expression and set it equal to 0.
(x - 9)(x + 10) = 0

Set each binomial into two equations.
x - 9 = 0 and x + 10 = 0

Solve for x and we get two answers.
x = 9
x = -10


HELP PLEASE !!!
What is the vertex of this parabola?
y-5 = x^2?



Answers

Answer:  (0,5)

====================================================

Work Shown:

y-5 = x^2

y = x^2 + 5 ... add 5 to both sides

y = 1x^2 + 5

y = 1(x-0)^2 + 5 ... x replaced with (x-0)

The equation is now in the form y = a(x-h)^2 + k

We have a = 1, h = 0, k = 5.

The vertex is (h,k) = (0,5)

The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.

The ratios in an equivalent ratio table are 3:12, 4:16, and 5:20. If the first number in the ratio is 10, what is the second number? Justify your reasoning

Answers

You’re multiplying each first number by 4 to get to the second. So, if you have 10, the second number would be 40.

Hope this helps!!

Answer:

The second number is 40, because the first number is 5 times 2, so the second number is 20 times 2. Each ratio simplifies to be 1:4.

1/3 (b+6)=1/4b +8

Answers

Answer:
b=72

Explanation:
1/3(b+6)=1/4b+8
Distribute 1/3 into the parentheses
1/3b+2=1/4b+8
Move like terms to either side
1/3b-1/4b=8-2
1/12b=6
Divide both sides by 1/12 to isolate b
b=6/ 1/12
Dividing a fraction is the same thing as multiplying its flip
b=6(12)
b=72

A and B are vertical angles. If mA=(7x-20° and mB =(6x-1)º, find the
measure of A.

Answers

Dfhhhgffvbhhtggg hhdfvbug

Answer:

[tex]\angle A=113\textdegree[/tex]

Step-by-step explanation:

We know that ∠A and ∠B are vertical angles.

Remember that vertical angles have the same measure. So:

[tex]\angle A=\angle B[/tex]

Substitute them for their equations:

[tex]7x-20=6x-1[/tex]

Solve for x. Add 20 to both sides:

[tex]7x=6x+19[/tex]

Subtract 6x from both sides. So, the value of x is:

[tex]x=19[/tex]

To find ∠A, we can use its equation again:

[tex]\angle A=7x-20[/tex]

Substitute 19 for 7:

[tex]\angle A=7(19)-20[/tex]

Multiply and subtract:

[tex]\angle A=133-20=113\textdegree[/tex]

So, the value of ∠A is 113°.
