Identify the graph of the following equation.

x < -3

Answers

Answer:

The 1st Graph (A)

Step-by-step explanation:

Test by substituting values for "x":

By substituting the numbers of 0 (0 < -3), -1 (-1 < -3), and -2 (-2 < -3), does that make the statement true?

The answer is FALSE. None of those values are satisfactory.

Therefore, by substituting -4 (-4 < -3), -5 (-5 < -3), and -6 (-6 < -3), these values are satisfactory and makes the statement true.

First add 10 to both sides of the equal sign so -10+10 and 15-10 -10+10 cancels out so you are left with -2X and 15-10 is gonna be 5
Second ; you’re left with -2X=5
Last your are gonna divide both steps by -2
So you’re gonna have x= -2.5 or -5/2=-2 1/2(simplified)
-2x-10=15
-2x=15+10
-2x=25
-x= 25/2
-x= 12.5
variable is never negative hence shift the -ve to right
answer is x= -12.5

195
409

Answers

Answer:

409

Step-by-step explanation:

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.

1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

The only number which has 9 as its final digit is 409

409 because if multiply 9 and 296

Step-by-step explanation:

When doing divison of fractions, you do these steps

11/3 ÷ 2/3 you turn the division sign to a multiplication sign, but by doing that you will have to turn 2/3 to 3/2.

11/3 × 3/2. Now all you have to do is multiply

11/3 × 3/2 = 33/6, simplify that down is 5 3/6, which is 5 1/2

Evaluate. Write your answer as a fraction in simplest form.
2/9 +5/12 -7/18

Answers

the answer will be 1/4

Answer:

1/4

Step-by-step explanation:

Step 1 : Find a common denominator. We will use 36 as the denominator since 9, 12, and 18 are all factors of 36.

Step 2 : The number you multiple the denominator by must be the same number you multiply its numerator by.

Example : 2/9    To get a denominator of 36 you need to multiply 9 by 4. Now you need to multiply 2 by 4 as well.

Step 3 : Convert fractions into the new fractions

2/9 (times 4 on both sides) = 8/36

5/12 (times 3 on both sides) = 15/36

7/18 (times 2 on both sides) = 14/36

Step 4 : Plug new numbers into the equation.

8/16 + 15/36 - 14/36

Step 5 : Solve

8/16 + 15/36 = 23/36

23/36 - 14/36 = 9/36

Step 6 : Simplify

9/36 (divide by 9 on both sides) = 1/4

Explanation:
1) domain is all possible x values the graph covers so you can see the arrows point bot direction meaning it will go on forever
2) range is all possible y values so the graph goes all the way up but stops at -4 when going down, but it doesn’t touch 4 so it’s a parenthesis not a bracket (which is used when it’s equal to that number)
3) as x increases in number from negative to positive than y is also increasing (based on the graph)
4) as x decreases it stops a -4 but and doesn’t pass this y value ( it’s finding the limit)
5) x intercept is when y=0
6) y intercept is when x=0

Volunteers at Sam's school use some of the student council's savings for a special project. They buy 3 backpacks for $7 each and fill each backpack with paper and pens that cost $6. By how much did the student council's savings change because of this project?

The savings was changed by
dollars.

Answers

Answer:

Sam's student council spent $39 on backpacks + paper and pens.

Step-by-step explanation:

They bought 3 backpacks for $7 each. 3 x 7 = $21.

They also filled those backpacks with paper and pens costing $6 each. 3 backpacks x $6 = $18.

Now, add the two prices.

18 + 21 = 39

hope this helps :)

The student councils savings decreased by $39.

Complete both Part A and Part B.

Part A:
Jason buys a pair of pants for $28.97, a top for $12.82 and a scarf for $9.18. He has a gift card worth $75. If the sales tax on the purchase is $3.19, what is the total of his purchase?

Part B:
Will he have enough money left to buy a hat for $27.15?
Explain your answer.

Answers

Answer:

Explanation:

Part A:

Total purchase = 28.97 + 12.82 + 9.18 + 3.19 = 54.16$

Part B:

75$ - (54.16 + 27.15) = 75 - 81.31 = -6.31

Therefore, he won’t have enough money to buy the hat.
Part a: When you add them all together you will get $54.16

Part b: no he won’t.

find the area of this figure

Answers

Answer:

164 sq. meters

Step-by-step explanation:

Area = length • width

Area = 12 • 15

Area = 180

Area = length • width

Take the area of the none shaded part

Area = 8 • 2

Area = 16

Now subtract 16 from 180

180 - 16 = 164
