Answer:

(2x-7)+ (-7)

Step-by-step explanation:

sum: 2x-7 + -2x

-7

an equivalent expression would be 3x-7-3x, or anything else that simplifies to -7

Answer:

The answer is two places to the right. For every 0 you move the decimal one place. And since the 100 is positive you move the decimal to the right.

Answer:

2x-18

Step-by-step explanation:

The distributive property has you mulitply the outside number by the inside numbers. 2 multiplied by x is 2x, and 2 multiplied by 9 is 18. We keep the subtraction symbol, this gives us 2x-18.

Answer:

y = (8/3)x - 3

Step-by-step explanation:

To get to slope intercept, just solve for y

3y - 8x = -9

3y = -9 + 8x

y = (-9 + 8x)/3

y = -9/3 + 8x/3  (distribute the 3 so we can reach the right form)

y = -3 + 8/3(x)

finally write in slope intercept form:

y = (8/3)x - 3

Selling price of a bicycle = 2850

Profit percentage = 14%

We know that :

[tex]\color{plum}\tt{Cost \: \: price = \frac{Selling \: \: price \: \times \: 100}{100 \: \: + \: \: profit \: \%} }[/tex]

Then, the cost price of this bicycle :

[tex] = \tt \frac{2850 \times 100}{100 + 14} [/tex]

[tex] = \tt \frac{285000}{114} [/tex]

[tex] =\color{plum} \tt2500[/tex]

Thus, the cost price of this bicycle = 2500

In another scenario :

Profit percentage = 8%

Cost price of the bicycle = 2500

Then, Selling price will be equal to :

Let x be the selling price of the bicycle.

[tex] = \tt2500 = \frac{\: x \: \times 100}{100 + 8} [/tex]

[tex] = \tt2500 = \frac{100x}{108} [/tex]

[tex] =\tt 100x = 2500 \times 108[/tex]

[tex] = \tt100x = 270000[/tex]

[tex] =\tt x = \frac{270000}{100} [/tex]

[tex] =\color{plum}\tt x = 2700[/tex]

Therefore, the selling price with a profit of 8% will be = 2700

Answer:

5) A

6) D

Step-by-step explanation:

for 5) I did just looked up online

2.5% of 25,000

and I added it to 25,000

which was 26,265.625

so I looked up 2.5% of 26,265.625 and I kept doing it until the 5th year and I got estimated $28,285.21

for 6) I did similar to 5) but I used the numbers that were given

I looked up 4% of 1,250 and I did that twice and got $1,352.55

hope that helped ;)

Answer:

1 Binomcdf (10,1/6,3)

Step-by-step explanation:

Step-by-step explanation:

The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.

She writes the equation r = 15t (r = 0.2t) to describe the relationship.

In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.

The number of cups of red paint is a dependent variable as it depends on the number of cups.

Answer:

300

Step-by-step explanation:

Answer:

10 pallets would weigh 300 pounds

Step-by-step explanation:

6 pallets = 180 pounds

10 pallets = x pounds

Cross multiply;

6x = 1800

Divide both sides by 6;

x = 300

Answer:

SAS

Step-by-step explanation:

the lines in the middle of a segment mean that they are equal in length.

So OE = EB and AE = EC.

Now, since angle AEB and angle DEC are vertical angles, they are equal.

Therefore the triangles are equal by SAS

Answer:

The conclusion is incorrect because the range is limited to the set of positive real numbers.

Step-by-step explanation:

The conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.

A relation is a function if it has only One y-value for each x-value.

Statement 1 is actually correct, because as x increases by 1, the value of f(x) = 2x is multiplied by 2.

Therefore, the y-values are indeed doubled for each single increase in x.

Statement 2, however, is incorrect, because as x decreases by 1, the value of f(x) is divided by 2, not halved.

Therefore, the accuracy of Geraldine's statements is mixed.

The range of the function f(x) = 2x includes all positive real numbers, not just integers or positive integers.

Therefore, the conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.

Answer:

a. 16

Step-by-step explanation:

Consider these 3 values.

[tex] \sqrt{16} \\ \sqrt{27} \\ \sqrt{35} [/tex]

Factor 16,27 and 35.

[tex] \sqrt{4 \times 4} \\ \sqrt{3 \times 3 \times 3} \\ \sqrt{3 \times 3 \times 5} [/tex]

Pull out two same numbers out of the root.

[tex]4 \\ 3 \sqrt{3} \\ 3 \sqrt{5} [/tex]

Rational only when there are no square roots after simplify/evaluating.

Thus a. 16 is only rational here.

Answer:

Can not be determined

Step-by-step explanation:

In order to find the value of y for x = 4 you need to have a relation between x and y, which is not given. So you can't determine the value of y.

Answer:

The correct option is;

A. It is a one-to-one function

Step-by-step explanation:

A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.

The given graph has a domain of -2 ≤ x < ∞

Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function

Step-by-step explanation:

10 gallons of gas is $29.50

10 gallons of gas = $29.50

10 gallons of gas / 10 = $29.50 / 10

1 gallon of gas = $2.95

Per x gallons of gas,

1 gallon of gas * x = $2.95 * x

x gallons of gas = $2.95 * x
