solve -2(x + 4) + 9 < -11 then graph.

Answer:

a) 7 tiles

b)4 1/3 tiles*

Step-by-step explanation:

*you would need 5 tiles if the answer isn't supposed to be a fraction. 4 1/3 is the exact amount but if they are asking for whole tiles you need to put 5. since they didn't actually specifiy that i don't think you have to worry about it. i would go with 4 1/3 tiles

Answer:

C

Step-by-step explanation:

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.

C is correct. If the scale factor is greater than 1, the image is an enlargement. The segment UT could be an enlargement of the segment ST.

Step-by-step explanation:

A. If > 1, then the image of could be .  

B. If 0 < < 1, then the image of could be . ( If the scale factor is between 0 and 1, the image is a reduction )

C. If > 1, then the image of could be .

Answer:

[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

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.

The answer is 12 − 10

Given:

The table of values.

To find:

The y-intercept of the given function.

Solution:

The table of values represents a linear function because the rate of change is constant.

Consider any two points from the given table. Let the two points are (-2,15) and (1,6). Then the equation of the linear function is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-15=\dfrac{6-15}{1-(-2)}(x-(-2))[/tex]

[tex]y-15=\dfrac{-9}{1+2}(x+2)[/tex]

[tex]y-15=\dfrac{-9}{3}(x+2)[/tex]

[tex]y-15=-3(x+2)[/tex]

Adding 15 on both sides, we get

[tex]y=-3x-6+15[/tex]

[tex]y=-3x+9[/tex]

Putting x=0, we get

[tex]y=-3(0)+9[/tex]

[tex]y=0+9[/tex]

[tex]y=9[/tex]

The y-intercept is 9. Therefore, the correct option is C.

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

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

33-7=26/2=13, so there were 13 friends
