Answer:

C. x - 5y - 30 = 0

Step-by-step explanation:

Y = x/5 - 30

y + 30 = x/5

you multiply both sides by 5

5y + 30 = x

you subtract x from both sides

- x + 5y + 30 = 0

which is the same as

x - 5y - 30 = 0

Answer:

y=10 when x=7

Step-by-step explanation:

y=2x-4

y=10

Substitute y with "10": 10=2x-4

Add 4 on both sides: 14=2x

x=7

Answer:

substitute 10 for y in the equation y=2x-4

10=2x-4

2x=10+4

2x=6

divide both side by 2

x=3

Answer:

x = 12

Step-by-step explanation:

First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:

-24 + x = -12

Adding 24 to both sides isolates x:  x = -12 + 24, or x = 12

Answer:

0.4 (not rounded)

Step-by-step explanation

You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 45 using

GCF(18,45) = 9

18÷945÷9=25

We know that

25

is the same as

2÷5

Then using

Long Division for 2 divided by 5

gives us

=0.4

Answer: 5

Step-by-step explanation: 6-1=5

Answer:

x=5

Step-by-step explanation:

To get the x alone, you would have to get the one away. To do that, you will have to get it to 0, by subtracting 1 from 6, making it five. Now x is alone like this: x=5

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

please help me i've been stuck on this question forever

Write a system of equations to describe the situation below, solve, and write as an ordered pair (with number of months as x). Two friends, Ann and Malia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Ann's hair is already 23 centimeters long and grows at a constant rate of 3 centimeters per month. Malia's hair is 27 centimeters and growing at a speed of 1 centimeter per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Ann's hair length: y = 23 + 3x

Malia's hair length: y = 27 + x

Thus: 23 + 3x = 27 + x

23 + 2x = 27

2x = 4

x = 2

Ann's hair length: y = 23 + 2(3) = 29

Malia's Hair length: y = 27 + 2 = 29

Solution: (x, y) = (2, 29)

In 2 months both Ann's and Malia's hair will be 29 centimeters long.

Let's start with Ann's hair: 23 centimeters + 3 centimeters per month

Malia's hair: 27 centimeters + 1 centimeter per month

Now we can substitute the number of months for "x"

Ann's hair length = 23 + 3x

Malia's hair length = 27 +1x

We know that we want both girls to have the same hair length at the end so we can set these two equations as equal to each other:

23 + 3x = 27 + 1x Subtract 23 from both sides

3x = 4 + 1x Subtract 1x from both sides

2x = 4 Divide by 2

x=2 Now we know it will take 2 months for their hair to be the same length!

Let's plug that in to our original equations:

Ann's hair length = 23 + 3(2) = 29 centimeters

Malia's hair = 27 + 1(2) = 29 centimeters

It will take 2 months for the girls to grow their hair to the same length of 29 centimeters.

As ordered pairs, with x as the number of months, we can use the length of the girls hair as the y value.

At 0 months, Ann's hair is 23 cm and Malia's is 27 cm so the first ordered pairs are (0, 23) and (0, 27).

At 1 month, Ann's hair grows 3 cm and Malia's grows 1 cm so the second pairs are (1, 26) and (1, 28).

Finally, at 2 months Ann's hair is at 29 cm and so is Malia's so the final ordered pair is (2, 29) for both girls.

If you were to draw these equations on a graph, (2, 29) is where the lines would intersect.

The required fill-in-the-blank below as:

1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given

2.) XV≅XV | Reflexive Property

3). SAS Triangle Congruence Property

Two triangles are said to be congruent if their corresponding sides and angles are equal.

The given in question as:

WX bisects ZXY,

ŽX =YX

To prove:

△ZXV ≅ △YXV

1.) ZW ⊥ XW, ZW ⊥ WY, ∠ ZXV ≅ ∠ YXV | Given

2.) XV≅XV | Reflexive Property

According to SAS, two triangles are congruent if the two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of the other triangle.

3). SAS Triangle Congruence Property

Hence, △ZXV ≅ △YXV

Thus, the required fill-in-the-blank above is in the solution.

Answer:

its A on the quiz (alternate interior)

Step-by-step explanation:

The required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

Given that,
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively. What angle relationship describes ∠VQR and ∠QRW is to be determined.

Parallel lines are defined as the pair of line that has the distance between the point corresponding to the line are equal and this line met at infinity.

The angle can be defined as the one line inclined over other line.

Since it is to describe that what is the relationship between  ∠VQR and ∠QRW.
Here, both angles are interior and alternate in the figure so both angles have a relationship to the alternate interior angle by property of parallel lines.

Thus, the required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.
