Someone please help!
lutik1710 [3]

Answer:

All are correct

Step-by-step explanation:

If Friend A gives 145 and Friend C gives 245 they already have a total of $390 out of the $700. So the missing amount is 310, half that for both friends and get 155, so the last 2 could both pay 155. No matter which way you put the number you will get the same answer. And as the communitive property states "The numbers on which we operate can be moved or swapped from their position without making any difference to the answer." and all of the answer choices apply to that statment.

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0?
ipn [44]

Answer:

We have to determine the graph of the given inequality as:

x^2+2x+1>0

on solving this equation we get:

(x+1)^2>0

Since we know that:

(x+1)^2=x^2+1^2+2\times x\times 1\\\\(x+1)^2=x^2+1+2x

Now we know that when x=-1 the value of:

(x+1)^2=0

Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.

Hence, range of the function in intervals could be written as:

(-∞,-1)∪(-1,∞).

Hence, the graph of the function will be the whole of the number line with a open circle on -1.

Phildell Phoenix is paid monthly. For the month of January of the current year, he earned a total of $8,288. The FICA tax for so
Yuliya22 [10]

Answer:

The net pay = 6278.79 dollars

Step-by-step explanation:

Net pay = gross pay - (federal income tax + FICA-Social Security tax + FICA-Medicare Tax).

gross pay = 8288 dollars

While

FICA social security tax:

6.2% of $8288

8,288 × 6.2/100 = 513.86.

FICA-Medicare tax: 1.45% of $8288

8,288 ×1.45/100 = 120.18

The net pay = 8,288 - (1,375.17 + 513.86 + 120.18).

= 8288 - 2009.21

The net pay = 6,278.79 dollars
