The value of y will be 60 so the correct answer is option C.

<h3>What is a graph?</h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

There is a linear relationship between the two variables x and y. For the given data in the table as well as in the graph. The expression for the two variables will be written in the form of an equation as follows:-

The expression for the data in the table:-

y = 25 x now at x = 12

y = 25 x 12 = 300

The expression for the values in the graph:-

y  = 30x at x = 12

y  = 30 x 12

Y = 360

How much more would the value of y be on the graph will be calculated as:-

Value  = 360 - 300

Value = 60

Therefore the value of y will be 60 so the correct answer is option C.

The volume of a landfill doubles every three years. Write an exponential function to represent this.
stellarik [79]
The equation would be: V = A2^(Y/3)

The basic form of an exponential equation is y = ab^x.

The a is the starting amount. In this problem, we don't know that, so we just leave it as a.

The b is the rate. In this case, we are doubling the volume so we times it by 2.

The x is the amount of years. Since it is every 3 years, we can divide the x by 3.

Find the truth set of each predicate.
Sedbober [7]

The truth set for each predicate are:

a) d ∈ { -6, -3, -2, -1, 1, 2, 3, 6}

b) d ∈ {  1, 2, 3, 6}

c) x ∈ { [-2, -1] U [1, 2]}

d) x ∈ {-2, -1, 1, 2}

<h3>How to find the truth set of each predicate?</h3>

We only need to find the sets of values such that the statements are true.

a)

We want to find vales of d, such that d is an integer, and 6/d is an integer.

Here the possible values of d will be:

d ∈ { -6, -3, -2, -1, 1, 2, 3, 6}

Which are all the factors of 6, so all these integers divide 6.

b) Same as before, but this time the domain is a positive integer, so now the truth set will be:

d ∈ {  1, 2, 3, 6}

c) We want to find real values of x such that:

1 ≤ x² ≤ 4

If we apply the square root to the 3 sides, we get two inequalities:

-√1 ≥ x ≥ -√4

√1 ≤ x ≤ √4

Simplifying:

-1  ≥ x ≥ -2

1  ≤ x ≤ 2

So the truth set is:

x ∈ { [-2, -1] U [1, 2]}

c) Same as before, but now we only have integer solutions, so the truth set is:

x ∈ {-2, -1, 1, 2}

Situation: You want to buy three books that are on sale at 20% off. The original prices of the books are $2.50, $4.95, and $6.00
frozen [14]

Answer:

$2.69

Step-by-step explanation:

Distribution method:

.20(2.50, 4.95, 6.00)

(0.50, 0.99, 1.20)

Now add them up.

Non-distribution method:

$2.50 x .20 = 0.50

$4.95 x .20 = 0.99

$6.00 x .20 = 1.20

Add them up
