Points in Quadrant IV have a positive x, and a negative y.
14.
The point (2,9) is reflected over the y-axis, which means the number in x has it's sign flipped.
(-2 , 9) is your answer
15.
In between -7 & -4 is <em>-6, -5</em>
b. -6 is your answer.
16.
Remember that Quadrant II has a negative x, and a positive y. This means that b. (-2, 5) is your answer.
17.
You are reflecting over the y-axis, so you are changing the sign of the x value.
(-3, 5) reflected over the y-axis is a. (3 , 5)

Magnify the ant 5 times and magnify the crab spider 4 times so they can both be 20.
x = a number
4x - 63 = x
Subtract 4x from both sides.
-63 = -3x
Divide both sides by -3
21 = x
Hi!
To solve this, we need to know how much the earrings and necklace cost together, then we need to know if it's more or less than how much she has ($20)
So first, add the costs together.
7 . 5 8
+ 1 3 . 3 6
---------------
2 0 . 9 4
The necklace and earrings cost $20.94 which is more than $20.
The answer is no, Doreen does not have enough money.
Hope this helps! :)

Answer:
4 weeks
$28
Step-by-step explanation:
Let
x = number of weeks
Jamal's savings = 18 + 5x
Samuel's savings = 10 + 7x
Equate both savings
Jamal's savings = Samuel's savings
18 + 5x = 10 + 7x
18 - 10 = 7x - 5x
8 = 2x
x = 8 / 2
= 4
x = 4 weeks
Check:
18 + 5x
18 + 5(2)
18 + 10
= $28
Each boy would have saved an equal amount of $28 at the end of the 4th week
