Note that when a point P(a, b) is reflected with respect to the y-axis, the y coordinate does not change, while a becomes -a.
So the reflection of a point P(a, b) with respect to the y-axis is the point P'(-a, b).
According to this, the projections of the points (2,3), (-4,-5), and (-2, 4) are the points the points (-2,3), (4,-5), and (2, 4).
Answer: A
Answer:
-122
Step-by-step explanation:
f(5)= 5- 8×5² + 13×5 +8
= 5 - 200+ 65+8
=78 -200
= -122
X=120
2/5-(x/300)=0
Simplify= X/300
2/5-X/300=0
Simplify=2/5
2/5-X/300=0
The left denominater is: 5
The right denominater is: 300
Answer:
The possible values of the number of dollars in the original pile of money is ≥ $200 but < $350
Step-by-step explanation:
Here we have, pile of money ≥ $200
Amount in put the left pocket = $50
Fraction given away = 2/3 of rest of pile ≥ 2/3×150 ≥ $100
Amount put in right pocket = ≥ $150 - $100 ≥ $50
Total amount remaining with Jeri = $50 +≥ $50 ≥ $100
Also original pile - $200 < $100
Therefore where maximum amount given away to have more money = $200 we have
2/3× (original pile - 50) = $200
Maximum amount for original pile = $350
Therefore the possible values of the number of dollars in the original pile of money is ≥ $200 but < $350.
Answer:
Step-by-step explanation:
The missing options are:
For this exercise it is important to remember the mulitplication of signs:
By definition, the sum is the result of an addition.
Therefore, you need to add the numbers given in the exercise (-15 and 6) in order to find its sum. This is:
(Since the greatest number has a negative sign, the sum is negative).
Knowing this, you can check each option to find the expression whose sum is -9:
The answer is the option "d".
