Answer:

The answer is D) (-1, -1)

Step-by-step explanation:

In order to find which answer is a solution, you have to put the ordered pair in for their given variables. If it produces a true statement, then it is a solution. In this case, D is the only one that produces a true statement.

2x + y > -4

2(-1) + (-1) > -4

-2 - 1 > -4

-3 > -4 (TRUE)

zasha spent $6 on packages of gum.How many more packages of gum that cost $1.20 each can she buy if she has a $20 bill

antiseptic1488 [7]

You have to make an inequality:
1.2x + 6 ≤ 20
- 6 - 6 isolate x

1.2x ≤ 14
÷1.2 ÷1.2 isolate x

x ≤ 11.666

Since you can't buy 2/3 of a pack, she can only buy 11 pieces of gum.

Question 3 of 14

Answer:

$\$84,000$

Step-by-step explanation:

Remember that

$6\%=6/100=0.06$

we know that

The amount the salesman would earn in a year must be equal to the base salary multiplied by 12 (number of months in a year) plus 6% of the amount sold in merchandise in a year

$4,000(12)+0.06(600,000)=\$84,000$
