Answer: Sue is 20 and Jennifer is 26
Step-by-step explanation:
Let's say that J=Jennifer's age now and S=Sue's age now.
We know that:
J=S+6
Because Jennifer is 6 years older than Sue.
We also know that when Jennifer is 4 years older (J+4), she will be twice as old as Sue was 5 years from now (S-5).
So we get the following equation from that information:
J+4=2(S-5)
So we have the two equations:
J+4=2(S-5)
J=S+6
Let's substitute J=S+6 into the first equation (note that RHS means Right Hand Sie and LHS means Left Hand Side):
(S+6)+4=2(S-5)
S+10=2S-10 [Add 6+4 on the RHS, and distribute on the LHS]
S=2S-20 [Subtract 10 from both sides]
-S=-20 [Subtract 2S from both sides]
S=20 [Divide both sides by -1]
So we know S, which is Sue's age, is 20. So Sue is no 20 years old.
Finding Jennifer's age now is simple. We know Jennifer is 6 years older than Sue, and Sue is 20, so Jennifer is 26 years old.
Answer:
x=-2
Step-by-step explanation:
-9x+1=-x+17
Add 9x on both sides:
1=8x+17
Subtract 17 on both sides:
-16=8x
Divide both sides by 8:
-2=x
Check x=-2!
-9x+1=-x+17 with x=-2
-9(-2)+1=-(-2)+17
18+1=2+17
19=19
19=19 is a true equation so x=-2 is correct.
The translation that maps triangle ABC to A prime B prime C prime would be a reflection across the y axis. This is because when you reflect something, you are pretty much flipping it. When you reflect across the y axis, you are flipping the triangle across the y axis. Take one point for example. I will use C. Notice how the point C is 3 units away from the y axis. So the same way you would move the point 3 units right from the y axis, and that would be your new point. This sounds kind of complicated, so I will give you a list of rules to make it more simple.
Reflection across y axis: (x,y) would be equal to (-x, y)
Reflection across x axis: (x,y) would be equal to (x, -y)
Reflection across y = x: (x,y) would be equal to (y,x)
Reflection across y = x: (x,y) would be equal to (-y,-x).
A reflection across y = x would be when you have a line that for every 1 it rises, it goes right 1. It is a positive line, as opposed to the y = -x line. It also has a slope of 1. I will try attaching a graph if I can.
Anyway, as I was saying. So pretty much if you don't want to go through the logic, to see whether a figure is reflected, just try each of these rules and if one works then you have your answer. Otherwise it would not be a reflection.
Thanks for being a great mod and hope this helps! :D
Answer:
15 or 14
Step-by-step explanation:
I hope you meant Parking B as in Basement bcoz that's what i got
If you are in the US you should probably choose 14 since ground floor is not considered a floor.
For 15, I added plus ground floor.
