Answer: - 2x^2 + 4x + 3

Step-by-step explanation:

( -x^2 - 4x - 5) + ( -x^2 + 8x + 8)

Take out parentheses:

- x^2 - 4x - 5 - x^2 + 8x + 8

Write in a way so that like terms are grouped together:

- x^2 - x^2 - 4x + 8x - 5 + 8

Combine 'x^2' terms:

- 2x^2 - 4x + 8x - 5 + 8

Combine 'x' terms:

- 2x^2 + 4x - 5 + 8

Combine integers:

- 2x^2 + 4x + 3

greg needs $51 to go on a field trip. he has saved $12.75. he earns $6.50 per hour cleaning his neighbor's garden, and he earns $5.25 per hour selling cakes at a store. can greg go on the field trip if he works at the garden for 2 hours and at the store for 5 hours? (use the inequality 6.50x 5.25y 12.75 ≥ 51.) yes, because the total will be $62 yes, because the total will be $52 no, because the total will be $50 no, because the total will be $49

Answers

The answer should be yes because the total will be 52. I am not sure how to use the inequality but this is how I would do it. (6.50 × 2) + (5.25 × 5) + 12.75 = 52 which is greater than 51.

^-^ Hi Friends!!!

Your answer is B.

Yes, because the total will be $52

Jane Hilman went to her bank. She had a balance of $1,009.88 in her savings account. She withdrew $130.00 and the teller credited her account with $6.19. What is her new balance? $886.07 $873.69 $1133.69 $1146.07

Answers

"Credit your checking account," means the transaction will increase your checking account balance. So first subtract $130 from $1009.88 and you get $879.88. Then add $6.19 for the amount the banker credited and you get $886.07 Hope this helped.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is . For one performance, advance tickets and same-day tickets were sold. The total amount paid for the tickets was . What was the price of each kind of ticket

Answers

Answer:

Advance tickets=$25

Same-day tickets=$15

Step-by-step explanation:

Complete question below:

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?

Let

advance tickets=x

Same-day tickets=y

Combined cost of advance and same-day tickets=$40

It means,

x+y=40 Equ (1)

25 advance tickets and 30 same-day tickets=$1075

It means,

25x+30y=1075 Equ(2)

From (1)

x+y=40

x=40-y

Substitute x=40-y into (2)

25x+30y=1075

25(40-y)+30y=1075

1000-25y+30y=1075

5y=1075-1000

5y=75

Divide both sides by 5

5y/5=75/5

y=15

Recall,

x+y=40

x+15=40

x=40-15

=25

x=25

Advance tickets=$25

Same-day tickets=$15

Check

25x+30y=1075

25(25)+30(15)=1075

625+450=1075

1075=1075

If n denotes a number to the left of 0 on the number line such that the square of n is less than 1/100, then the reciprocal of n must be _______.A. less than -10B. between -1 and -1/10C. between -1/10 and 0D. between 0 and -1/10E. greater than 10

Answers

Answer: E. Greater than 10

Step-by-step explanation:

First, know that number to the left of a number line are negative and the square of any negative number will be positive and a perfect square.

Since the square of the unknown number is less than 1/100 i.e 0.01 then the possible unknown number 'n' can be -0.01 itself, of which the square of -0.01 will give us 0.0001 (1/10,000) i.e a value less than 0.01.

The reciprocal of 1/10000 is 10,000 which is a value greater than 10.
