What is the slope of the line that passes through the poiņts (-10, 4) and (-10,8)?
Write your answer in simplest form.

Answers

Answer:

Slope is undefined

Step-by-step explanation:

Slope is calculated by [tex]\frac{y1-y2}{x1-x2}[/tex] so now you put the points (-10,4) and (-10,8) into that.

Since both x values are the same you can tell that the line is a vertial line meaning the slope is undefined.

$42,000
$50,000
$52,000
$60,000

Answers

Answer:

$50,000

Step-by-step explanation:

The computation of the amount received after paying off the mortgage is shown below

= Value of the house - mortgage amount

= $150,000 - $100,000

= $50,000

By deducting the mortgage amount from the value of the house we can get the amount received and the same is shown in the computation part

Since in the question it is given that the Rosetta sells her house and paid off mortgage so only these two items are considered and others are to be ignored

y=x²-6x+8 what is y when x is 0?

Answers

Answer:

The value of y is 8.

Step-by-step explanation:

In order to find the value of y, you have to put in x = 0 into the equation :

[tex]y = {x}^{2} - 6x + 8[/tex]

Let x = 0,

[tex]y = {0}^{2} - 6(0) + 8[/tex]

having a small brain moment, can you please help and show work

Answers

Answer:

The value if x is 0.9875.

Step-by-step explanation:

First, we have to get rid of brackets by expanding :

[tex]0.5(2x + \frac{3}{4} ) - \frac{1}{3} (0.1 + x) = 1[/tex]

[tex]0.5(2x) + 0.5( \frac{3}{4} ) - \frac{1}{3} (0.1) - \frac{1}{3} (x) = 1[/tex]

[tex]x + \frac{3}{8} - \frac{1}{30} - \frac{1}{3} x = 1[/tex]

Next you have to collect like terms :

[tex]x - \frac{1}{3} x + \frac{3}{8} - \frac{1}{30} = 1[/tex]

[tex] \frac{2}{3} x + \frac{41}{120} = 1[/tex]

Lastly, you can solve x :

[tex] \frac{2}{3} x = 1 - \frac{41}{120} [/tex]

[tex] \frac{2}{3} x = \frac{79}{120} [/tex]

[tex]x = \frac{79}{120} \div \frac{2}{3} [/tex]

[tex]x = \frac{79}{80} [/tex]

[tex] x = 0.9875[/tex]

Answer:

1/12 ( -x -4 )

Step-by-step explanation:

1/12 ( -x - 4 )

1/12(-x) = -1/12x  Multiply 1/12 and -x to get -1/12x.

1/12 x -4 = -1/3  Multiply 1/12 and -4 to get -1/3.

So, therefore, the expression 1/12 ( -x - 4 ) is equivalent to -1/12x - 1/3.

What percent of alien races think invading Earth is a bad idea?

Answers

Answer: 90%

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 9/10 as a percent, we need to find a fraction

equivalent to 9/10 that has a 100 in the denominator.

We can do this by setting up a proportion.

So we have [tex]\frac{9}{10} = \frac{n}{100}[/tex].

Now, we can use cross-products to find the missing value.

So we have (9)(100) which is 900 is equal to (10)(n) or 10n.

So we have 900 = 10n.

Next, dividing both sides of the equation by 10, we have 90 = n.

So, 9/10 is equal to 90/100 or 90%.

Answer:

90%

Step-by-step explanation:

9/10 times 100 is 90%

What is the volume of the pyramid?
12 in
8 in
10 in
120 in
320 in
480 in
960 in

Answers

Answer:

B. 320 inches cubed

Step-by-step explanation:

A pyramid's volume is denoted by: V = (1/3) * B * h, where B is the base area and h is the height.

Here, the base is a rectangle with dimensions 10 inches by 8 inches. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. The length is 8 and the width is 10, so plug these in:

A = lw

A = 8 * 10 = 80

So, we know that B = 80.

We are also given that the height is h = 12, so plug these values into the volume formula:

V = (1/3) * B * h

V = (1/3) * 80 * 12 = 320

The answer is thus B.

Answers

Answer:

the answer is 12 degrees

The measure of angle ACB when the secant BC and the tangent AC intersect is 12°

Secant and Tangent intersection

When a secant and a tangent meet outside the circle, thwe product of the length of the secant and its external segment equals the square of the length of the tangent segment.

Therefore,

arc XA = 2(64) = 128 degrees.

Hence,

m∠C = 1 / 2 (152 - 128)

m∠C = 1 / 2 (24)

m∠ACB = 12°

Therefore, angle ACB is 12 degrees.

What percent of the voters were in favor of

What percent of the voters were against of
building the shopping center?

Answers

Add the two numbers together to find total votes:

3,400 + 15,600 = 19,000 total votes.

Divide votes for by total votes:

3,400 / 19,000 = 0.1789

Multiply by 100:

0.1789 x 100 = 17.89% voted for it.

Subtract the percent that votes for it from 100%

100% - 17.89% = 82.11% voted against it.

The answers probably need to be rounded, so 18% for, and 82% against.

You spin the spinner twice.

What is the probability of landing on a 4 and then landing on a 4?

Simplify your answer and write it as a fraction or whole number.

Answers

Answer: 1/16

Step-by-step explanation: It's important to understand that the two spins are called independent events because the outcome of the first spin does not affect the outcome of the second spin.

To find the probability of independent events, we first find the probability of each event, then we multiply the probabilities together.

Since there is one 4 on the spinner and four possible outcomes, each of which is equally likely, the probability of spinning a 4 is 1/4.

This mens that 1/4 is the probability of

getting a 4 on the second spin too.

Now we multiply.

1/4 x 1/4 gives us 1/16.

So the probability of spinning a 4 twice is 1/16.
