Which statement correctly describes the diagram? Help it’s 8th grade 3x ams and I really need help ASAP , I already failed twice and this is my LAST attempt

Answer:

greater

Step-by-step explanation:

the reason is because if you allow x to have a value that is less than 3,

[tex] \sqrt{x - 3} [/tex]

will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction

[tex] \frac{3}{x + 2} [/tex]

if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

Answer:

Linear, y=6x-21

Step-by-step explanation:

Graph the answer to get an idea of the shape: linear.

Use y=mx+b and m=y2-y1/x2-x1 to find formula

m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6

y=6x+b

9=6(5)+b

9-30=b=-21

y=6x-21

Answer:

84

Step-by-step explanation:

To complete the concrete highway with pavers 84 pavers are needed.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

A= 20 + 0.75*j

j= number of cups

For example, for 15 cups:

A= 20 + 0.75*15

A= $31.25

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Answer:

50

Step-by-step explanation:

Answer:

You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

There are more adults than children so the ratios made have to depict this.

These ratios should add up to 16.

Three different ratios:

11 adults : 5 children

9 adults : 7 children

13 adults : 3 children

The above will all add up to 16 and show more adults than children.

The different ratios of adults to children that might be on the bus is;

Answer:

9

Step-by-step explanation:

We are given that

Cost of each banana=$0.90

Cost of each orange=$0.80

Ava have total money=$15

We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.

Let x be the number of each.

According to question

[tex]0.9x+0.8x=15[/tex]

[tex]1.7x=15[/tex]

[tex]x=\frac{15}{1.7}[/tex]

[tex]x=8.8\approx 9[/tex]

[tex]x=9(approximately)[/tex]

Hence, number of banana bought=9

Number of oranges bought=9

so u add then together and get [tex]3\\ 5[/tex] and add that 5 times

so u would get [tex]15\\ 5[/tex] and if u simplify u would have 3 whole pizzas left

1: 121, 2: 59, 3: 59

This is for the first graph because if you look at the bottom half of a circle is 180 so since one is 121 you just have to subtract 121 from 180 and you have your answer
