Answer:

One number is 4.2, the other is 18.8

Step-by-step explanation:

1.)  x+y=23

    (x+6y)x2=4

2.) (x+6y)x2=4   =   2x+12y=4

3.)Use elimination/substitution to solve

     2x+12y=4  =   x+6y=2  =  x=2-6y

     2-6y+y=23

4.)Solve for y

     2-5y=23 -> -5y=21 -> y=4.2.

5.)Solve for x

    x+4.2=23

    x=18.8

Step-by-step explanation:

-5x+26=-44

-26        -26

-5x=-70

5       5

x=14

Answer:

x=14

Step-by-step explanation:

Let's solve your equation step-by-step.

−5x+26=−44

Step 1: Subtract 26 from both sides.

−5x+26−26=−44−26

−5x=−70

Step 2: Divide both sides by -5.

−5x−5=−70−5x=14

x=14

Answer:

Kirby Middle School

The percentage of students who used Snap the most is given as:

= 44%

Step-by-step explanation:

a) Data and Calculations:

App   Number of Students

Face          8

Snap        22

Insta        20

Total      50

The percentage of Snap users = Number of Snap users/Total users * 100

= 22/50 * 100 = 44%

b) This represents the proportion of all the students surveyed about the use of social media app.  Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap.  This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.

Answer:

$532

Step-by-step explanation:

Hey There!

So to solve this problem the first thing that we want to do is find the cost of 1 ball

To do so we divide the total cost of 10 balls by 10

280/10=28 so each ball cost 28

now to find the cost of 19 balls we multiply the cost of 1 ball by 19

18x28=532

thus meaning 19 balls cost $532

Answer:

$532

Step-by-step explanation:

We need to find the cost of 1 ball and then multiply it by 19, here is the math:

280/10=28

Now we know that 28 is the cost of 1 ball.

28 x 19=532

The cost of 19 balls is $532

Answer:

A = strong negative correlation

B = positive correlation

C = very weak or no correlation

Step-by-step explanation:

Scatter plot A:

A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.

Scatter plot B :

Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.

Scatter plot C :

From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

Put 2 dots in the spot above 9 by clicking on the space above the numbers. Put 3 above 10. Put 2 above 11. Put 2 above 12.

Answer:

If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.

For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats

a function because no x value is repeating the x value is known as an independent value. Does that make sense?

"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."

If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.

For a relation to be called a function, the following holds true:

Each x-value (input) has it's own unique y-value (output).

A x-value cannot give two different y-values.

If an x-value repeats, the corresponding y-value must repeat.

Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

[tex]a^{2} +b ^{2} =c^{2}[/tex]

Step-by-step explanation:

a & b = the sides

c = hypotenuse

pythagorean theorem is used to find the missing length of a triangle not always tho, like if you have a 30°60°90° triangle or a 45°45°90° triangle

Answer:

a^2 + b^2 = c^2    

a = side of right triangle

b = side of right triangle

c = hypotenuse

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6
