which is the best description of the data in the scatter plot

The proportion is shown below and we cross multiply, do algebra, to solve it.

If you read the question, so will see this part:

if you multiply both sides of the equation by 3 you get 50 x equals 75

This is the part where there is a problem. You did say to multiply by 3 (both sides). But don't multiply the right hand side of "75" mistakenly.

The last part of this line should be "equals 75 times 3"

This is the mistake.

We know that Pablo earns $40 every month.

Then, to calculate how much he makes in a year, we use the fact that a year has 12 months.

Then, we can write:

Answer: he earns $480 per year.

Given a circle has a diameter = 10 feet

The circumference of the

We have here that all of these angles must sum 360 degrees since we have here a circle. Then, we have that:

Now, to solve this equation, we need to group and sum the like terms:

To isolate 11x, we need now to subtract 151 to both sides of the equation:

Divide both sides of the equation by 11:

We can check this solution if we substitute the value x = 19 in the original equation (after the simplification process):

Since the last result is TRUE, then the value for x = 19 is the correct solution.

In summary, the value for x = 19.

When a system of equations has infinite solutions, you'll end up with a statements that's true no matter what. For example, 6=6. Or when the graphs of the equations are the same exact line.

Then:

3x+4y=12 and

6x+8y=24 divided by 2: 3x+4y=12. That means they are the same exact line, so it has infinite solutions.

The answer would be the first one and the third one.

if we count the paths we have:

1. A to B the top part

2. Ato B the bottom part

3. we look after that A first top arrow, down one arrow and a straight line

and so on

i counted 12 different ways

In linear functions, the rate of change is equivalent to the slope of the line. In function A we already now the slope intercept equation, which means that we already now the slope of the function.

In this case, the slope of function A is -2 so is the rate of change.

To find the rate of change of function B, we need to use 2 of the ordered pairs in the formula to find the slope of a line:

Let's choose two of the given ordered pairs and replace for them in the formula. We are going to use (1,1) and (3,9):

The slope of function B is 4 so is the rate of change.

In conclusion, the correct choice is A. The rate of change of function A is -2. The rate of change of function B is 4.

We have the next information

In total, we have 231 students

van--- 7 students

bus - 25 students

in total, we have 15 vehicles

So our first equation is

x+y=15

where

x is the number of vans

y is the number of buses

The second equation is

7x+25y=231

so we will isolate the x of the first equation

x=15-y

then we substitute this equation in the second equation

7(15-y)+25y=231

105-7y+25y=231

then we sum like terms

18y=126

then we isolate the y

y=126/18

y=7

Then for the value of x we use the equation with the x isolate and we substitute the value of y

x=15-7=8

Therefore the answer is 8 vans and 7 buses

Translation h units to the right and compressed by a factor A:

Then, if g(x) is f(x) after the given transformations, it has the next equation:

Answer:

Yes

Explanation:

The coordinate (-2,5) corresponds to the point (x, y).

This means that:

x= -2 and y=5

To check if the coordinate land on the equation y=2x+9, calculate the value of y when x= -2

Therefore, the coordinate (-2,5) land on the linear equation y = 2x + 9.

Answer:

2/3 of an acre

Explanation:

To find the size of each area, we divide the area of the garden by 5. This gives

Now at this point we remind ourselves that if we are dividing a fraction by a number, then we can turn the division into multiplication by taking the reciprocal of the number.

The number we are dividing our fraction by in this case is 5. Now, the reciprocal of 5 is 1/5 and so we can write the above as

Multiplying the denominators together gives

Now dividing both the numerator and the denominator by 5 gives

Hence,

Therefore, the size of each area is 2/3 of an acre.

Given the statement 'whatever is done on one side of the equation must also be done on the other side of the equation”, the mathematical properties that described this statement is Property of equality.

For any equality operation, whatever is done on one sides must be carried out on the other side. For example, given the equation;

3x + 3 = 5

We can subtract 3 from both sides to have;

3x+3 - 3 = 5-3

3x = 2

Then we can divide both sides by 3;

3x/3 = 2/3

From the illustration above, you can see that what we did to the left hand side of the equation, we also did for the right. Hence the correct answer is Property of Equality

EH

X ^2 = 40^2 + 9^2 = 1`600 + 81 = 1681

X = square root of 1681

= ET = EH = X = 41 feet

NI

y ^ 2 = 9 ^2 + 9^2 = 81 + 81 = 162

y = square root of 162

NI = T I = y = 12.72 feet

The perimeter of the Kite = EN + ET + NI + TI = 41 + 41 + 12. 72 + 12. 72 = 107.44 feet

Step 1: Let's recall that Supplementary angles are two angles with a sum of 180∘

Step 2: Let's write the equation to solve the problem.

• Let x to represent the smaller angle,

• Let 5x to represent the bigger angle

Therefore, we have:

x + 5x = 180

6x = 180

Dividing by 6 at both sides:

6x/6 = 180/6

• x = You can calculate the value of x dividing 180 by 6 and that is the measure of the smaller angle.

• 5x = You multiply the value of x by 5 and that's the measure of the bigger angle.

Don't forget that the sum of both angles should be 180.
