A point moves in the plane in the following sequence.
A point moves down 2 units, reflects over the x-axis, moves right 4 units, and then reflects over the y-axis.
Which of the following points follows the sequence and has the same starting and ending point?
A. (2, 3)
B. (–1, 1)
C. (–3, –3)
D. (–2, 1)
Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

There were some people on a bus. Half of the people get off at the first stop and 11 people get on. Now there are 20 people on the bus. How many people were on the bus to begin with?
Answer:
18 people
Step-by-step explanation:
18/2=9
9+11=20
Answer:
18.
Step-by-step explanation:
this is because in order to find out how many were on the bus, you simply do 20 - 11 = 9. Than you must multiply 9 by 2 which equals 18. That gives you your answer.

Step-by-step explanation:
Kaitlyn is making big goods for charity bake sale he places a tray of scones a tray of muffins and a tray of cookies in the oven discounts bake for 15 minutes the muffins bake for 12 minutes and the cookies bake for 10 minutes when one trays done he removes it and replace it with another tray at the same I don't how many minutes after kaylan put the trays in the oven when he 1st remove the scones muffins and cookies at the same time
Answer:
So:
Counting from a given time t = 0min, we know that:
Each 15 mins she removes the scones
Each 12 mins she removes the muffins
Each 10 mins she removes the cookies.
So when will she remove both at the same time?
Well, this will happen in the smallest common multiple of 15, 12 and 10.
or at LCM(10, 12, 15).
How we find it?
well, in this case is easy.
All the multiples of 10 end with a zero.
So let's find the multiples of 12 and 15 that also end with a zero:
12*6 = 60
15*4 = 60
and
10*6 = 60
So the LCM(10,12,15) = 60.
Another way is by calculating:
10*12*15/(GCF(10,12)*GCM(12,15)*GCM(10,15)
Where GCF = greatest common factor.
Between 10 and 12 is 2.
Between 12 and 15 is 3
Between 10 and 15 is 5.
Then:
10*12*15/(2*3*5) = 60.
This means that 60 minutes after she starts, she will remove the scones, muffins and cookies at the same time.
Sean's grade breakdown goes something like this
60%- Test
20%- Homework
10%- Organization
10%- ALEKS (math website)
He got 85% on his test. Out of the 9 homework problems he has 100% on all of them. Then for the organization, it's 97% out of the 10% it makes up. He also has a 96 on ALEKS which makes up 10% out of the whole grade. What is his current grade percentage?
Answer:
90.3
Step-by-step explanation:
.6×.85=.51
.2×1.00=.2
.1×.97=.097
.1×.96=.096
weight in %, times, grade in %
then add them up
.51 + .2 + .097 + .096 = .903
.903=90.3%
The dance team traveled to a competition and traveled in two vans. The first van transported 2 adults and 5 students and cost $77. The second van transported 2 adults and 7 students and cost $95. Find the cost for one student to enter the competition.
Answer: $9
Step-by-step explanation:
Let the cost for adults be a
Let the cost for students be b.
The first van transported 2 adults and 5 students and cost $77. This will be:
2a + 5b = $77
The second van transported 2 adults and 7 students and cost $95. This will be:
2a + 7b = $95
2a + 5b = 77 ...... equation i
2a + 7b = 95 ........ equation ii
Subtract equation ii from I
-2b = -18
b = 18/2
b = $9
An student cost $9
Put the value of b into equation i
2a + 5b = 77
2a + 5(9) = 77
2a + 45 = 77
2a = 77 - 45
2a = 32
a = 32/2
a = 16
An adult costs $16
What is 3n² = 243
I NEED THIS ANSWER QUICKLY!!!!
Answer:
n=9
Step-by-step explanation:
You use reverse PEMDAS.
First you would divide by 3 on both sides. This should give you:
n²=81
Then you would find [tex]\sqrt{81}[/tex]. Which is 9.

2 1/3 ÷y=1 2/5 ÷(−1.1)
Answer:
y=-0.5462
Step-by-step explanation:
2.33/y=1.4/(-1.1)
1.4/(-1.1)=-1.272727 (this number is rounded so answers may vary a little)
2.33y=-1.272727
y=-1.272727/2.33
y=-0.5462

Find the measure of the missing angles.
Answer:
d = 103
e = 22
f = 55
Step-by-step explanation:
ok so the angles on the other side 22 and 103 are equal to 2 of the angles on the other side
the whole line is equal to 180
103 + 22 = 125
180 - 125 = 55
d = 103
e = 22
f = 55
Answer:
d = 103
e= 22
f= 55
Step-by-step explanation:
the opposite side of d equals 103 and they are adjacent which means they have the same measure
same goes to e the opposite side of it equals 22
and then for f a full line measure equals 180
so 103+22= 125
180-125= 55
there you have it :)
What is the slope and y-intercept of the linear equation y = 5x - 4?
m2 =
ь
Answer:
Where m is the slope and b is the y-intercept. So in this case m=5 and b=-4, or in other words the slope is 5 and the y-intercept is (0,-4) (since x=0 for all y-intercepts).
Answer:
The slope is 5 and the y-intercept is -4.
Step-by-step explanation:
The slope intercept formula is y=mx+b. 5 is the m and -4 is the b. Hope this helps!

QS bisects ∠PQR. If m∠PQS = (5x)⁰ and m∠RQS = (2x + 6)⁰, then what is m∠PQR? Draw a picture and label before solving. *
Answer:
m∠PQR = (7x + 6)⁰
Step-by-step explanation:
Please find the diagram in the attachment.
Mathematically, since the angle PQR is bisected by the given line, it means that;
RQS + PQS = PQR
Thus;
PQR = (2x + 6) + 5x
PQR = 2x + 6 + 5x
PQR = 7x + 6
m∠PQR = (7x + 6)⁰

Answer:
h=−6.28r2+s/6.28r
Step-by-step explanation:
Step 1: Flip the equation.
6.28hr+6.28r2=s
Step 2: Add -6.28r^2 to both sides.
6.28hr+6.28r2+−6.28r2=s+−6.28r2
6.28hr=−6.28r2+s
Step 3: Divide both sides by 6.28r.
6.28hr/6.28r=−6.28r2+s/6.28r
h=−6.28r2+s/6.28r
A recycling center was offering cash for different types of recyclables. For each pound of paper recycled they offered $1.41, for each pound of aluminum they offered $1.53 and for each pound of plastic they offered $0.33. Jerry took in 5 pounds of paper, 15 pounds of aluminum and 6 pounds of plastic. How much money did he earn?
Answer:
Total amount earn = $31.98
Step-by-step explanation:
Given:
Cost of paper = $1.41
Cost of aluminium = $1.53
Cost of plastic = $0.33
Amount of paper = 5 pound
Amount of aluminium = 15 pound
Amount of plastic = 6 pound
Find:
Total amount earn
Computation:
Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)
Total amount earn = $7.05 + $1.98 + $22.95
Total amount earn = $31.98

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x).
Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x
Why you do not have to do any computing or math do solve 15 x 0 x (13 + 7)? Explain.
Answer:
because when you do 15*0 it =0 so anything else multiplied by 0 is 0
