Answer:

I think the answer is B

Step-by-step explanation:

(I'm not great at math so pls don't use my answer unless its a last resort) Because when I divided each one they all ended up back at 4, with that being said; 4 ÷ 1 = 4 , 8 ÷ 2 = 4, 12 ÷ 3 = 4, and 16 ÷ 4 = 4. Those are in the c column.

Answer:

60

Step-by-step explanation:

The required number is 60.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given expression is,

4.5 is 7.5%

Let x be the number.

Therefore, 7.5% of x is 4.5

⇒ 7.5% of x = 4.5

⇒ 7.5% * x = 4.5

⇒ 7.5/100* x = 4.5

⇒0.075 x = 4.5

Dividing both side by 0.075 we get,

x = 4.5 / 0.075

Solving we get,

x = 60

this is the required number.

Thus,the required number is 60.

Answer: She should sell her artwork for $39.60 or almost $40.

Step-by-step explanation:

First you need to find out what 80% of 22 is, which is 17.6, then you add that price to the price of her supplies.

22+17.6=$39.60

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

a: As the x-values increase, the y-values tend to increase.

Answer:

[tex]x=3[/tex]

Step-by-step explanation:

The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:

[tex]7 = 2x + 1[/tex]

Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:

[tex]6 = 2x[/tex]

The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:

[tex]3 = x[/tex]

[tex]y\:=\:-x\:-\:1[/tex]

Please check the attached graph of the given system of equations

From the graph:

Point of Intersection:

It is clear from the attached graph that the two lines intersect at the point (-4, 3).

i.e. at x = -4, y = 3

Therefore, the point (x, y) = (3, -4) represents the solution of the given system of equations.

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5

=11x2-16x-3

Answer: 100 miles.

Step-by-step explanation:

Here , Flat fee = $ 5.00

Additional charge per mile = $ 0.05

Money spent = $ 10

Formula : Total Charge =  Flat fee + (Number of miles ) x (Additional charge per mile)

Let x= Number of miles

Substitute values , we get

10 = 5 + 0.05x

⇒ 0.05x= 5

⇒ x = 100

Hence, I took bike for 100 miles.

I hope this helps a bit.....I think I  got them right. :)

Step-by-step explanation:

For every increase in the x-value by 1,

the y-value decreases by -2.

(From 3 to 1 and from 1 to -1)

Hence, slope of line k

= Rise/Run = (-2)/1 = -2. (A)

Using it's formula, it is found that the slope of line k is of -2, hence option A is correct.

Given two points (x,y) on a line, the slope is given by the change in y divided by change in x.

In this problem, two of the points are: (1,3) and (2,1).

Hence, applying the division:

[tex]m = \frac{1 - 3}{2 - 1} = -\frac{2}{1} = -2[/tex]

The slope of the line is of -2, hence option A is correct.
