Answer:
1) A.
2) No
Step-by-step explanation:
1 is A because the shaded line extends over numbers greater than -8 but less than -1. The reason it is greater than or EQUAL to -1 is because the dot above -1 is shaded in.
2 is No because in order to solve this equation, you plug in the numbers from the coordinates into the inequality. An ordered pair is always structured as (x,y), so in this case x = -1 and y = 4. To solve, the first step is to plug the numbers in, and you end up with 4< 2(-1) +5.
Then, simplify by adding and multiplying as needed. Now you will end up with 4<-2 +5. Simplify again. Finally you end up with 4<3. The reason the answer is NO, not a solution is because the statement '4<3' (four is less than three) is false. if the equation had ended up being 4>3, then it would have been true.
Answer:
<u>17-(- 2 / 5j)</u>
Step-by-step explanation:
16 + (- 5 ) - 2/5j - 4/5 j + 6
\/ \/ \/
11- ( -2/5j ) + 6
From here you over the 6 over to the 11
11+6-(-2/5j)
\/
17-(-2/5j)
It can not be simplified farther I believe

Answer:
$52.44
Step-by-step explanation:
Long method:
1. Convert the percentage into a decimal (15/100 = 0.15)
2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)
3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)
Quicker Way (easier w/ a calculator)
1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)
2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)
In a single equation, it would be
![\frac{115}{100} \times 45.60 = 52.44](https://tex.z-dn.net/?f=%20%5Cfrac%7B115%7D%7B100%7D%20%20%5Ctimes%2045.60%20%3D%2052.44)
