What is the equation of the line in slope-intercept form?
O Y=2x-8
O y = 2x+8
O y=8x-2
O y = 8x+2

Answers

Step-by-step explanation:

since b = 8, it has to be

y = 2x + 8

that was the whole point of the exercise, as the general slope-intercept form is

y = mx + b

you determined m = 2 and b = 8, so there is your answer. I am not sure where your problem was, as you solved the actual important part yourself.

No; the element 5 occurs twice in the range.
Yes; for each element of the domain, there is only one element of the range.

Answers

Answer:

Yes; for each element of the domain, there is only one element of the range.

Step-by-step explanation:

A set (x,y) represents a function if for each value of x(domain), there is only one respective value of y(range).

In this question, yes, for each value of x(2,4,3,5,-2), there is only one respective value of y, so it represents a function.

The correct answer is given by:

Yes; for each element of the domain, there is only one element of the range.

Find the measure of each angle in the problem: complementary angles with measures 4x and 5x-18 degrees

Answers

Answer:

42 degrees and 48 degrees

Step-by-step explanation:

If they are complementary, that means they add up to 90 degrees, so

4x + 5x - 18 = 90,

Solving,

9x - 18 = 90

add 18 to both sides

9x = 108

divide both sides by 9

x = 12

Now, to find the angle measures of each you have to substitute x = 12 into both angles.

4x --> 4 * 12 = 48 degrees

5x - 18 --> 5 * 12 - 18 --> 60 - 18 --> 42 degrees

You weigh a gallon of liquid in science class and learn that it is approximately 7.7 pounds.

Complete the explanation of how you can adjust your answer without weighing the liquid again. Then give the weight in kilograms. If necessary, round your answer to the nearest tenth.

only right anwres

Answers

Answer:

7.7 pounds = 3.5 kilograms

Step-by-step explanation:

Given that,

Weight of a gallon of liquid = 7.7 pounds

We need to find weight in kilograms.

We must know the relation between pounds and kilograms and it is as follows :

1 kilogram = 2.20 pounds

1 pounds = (1/2.2) kilograms

7.7 pounds = (7.7/2.2) kilograms

= 3.5 kilograms

Hence, 7.7 pounds is equal to 3.5 kilograms.

Answer:

There is one solution (4,0)

Step-by-step explanation:

First, we will try to solve this system of equations.

I will rearrange 2x-5y=8 to isolate -5y.

The new equation would be 5y=2x-8.

Now we will add

2x -8 = 5y

with

-2x+8=5y

We get 0 = 10y

Divide by 10 and we get y = 0.

Now that we know the value of y, lets solve for x.

2x-8=5(0)

2x-8=0

Add 8

2x=8

Divide by 2 to isolate x

x = 4.

x=4 and y=0

The solution is (4, 0)

A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from each size. Let X represent the shop's profit on a randomly selected pizza. Here's the probability distribution of X along with summary statistics:
Small Medium Large
X = profit ($) 4 8 12
P(X) 0.18 0.50 0.32
Mean: μX = $8.56
Standard deviation: σx =$2.77
The company is going to run a promotion where customers get $2 off any size pizza. Assume that the promotion will not change the probability that corresponds to each size. Let Y represent their profit on a randomly selected pizza with this promotion. What are the mean and standard deviation of Y?

Answers

Answer:

The mean and standard deviation of Y is $6.56 and $2.77 respectively.

Step-by-step explanation:

Consider the provided information.

Let Y represent their profit on a randomly selected pizza with this promotion.

The company is going to run a promotion where customers get $2 off any size pizza.

Therefore, [tex]Y=\text{Profit}-\$2[/tex]

[tex]Y=X-\$2[/tex]

So the mean will be reduced by 2.

[tex]\mu_Y=\mu_X-\$2[/tex]

[tex]\mu_Y =\$ 8.56 - \$2[/tex]

[tex]\mu_Y =\$6.56[/tex]

If we add or subtract any constant number from a given distribution, then the mean is changed by the same number(i.e constant number) but the standard deviation will remain the same.

Therefore [tex]\sigma_Y=\sigma_X=2.77[/tex]

Hence, the mean and standard deviation of Y is $6.56 and $2.77 respectively.

Step-by-step explanation:

Given system:

4x - 2y = 22x + y = - 5

1) Solving the second equation for y:

2x + y = - 5 ⇒y = -5 - 2x

2) Substituting y into the first equation:

4x - 2y = 2 ⇒4x - 2( -5 - 2x) = 2Correct option is a)

3) Solving for x:

4x - 2( -5 - 2x) = 24x + 10 + 4x = 28x = 2 - 108x = -8x = -1

4) Solving for y:

y = -5 - 2xy = -5 - 2(-1) = -5 + 2 = -3y = -3
