ABC is translated left 3 units to form the image ∆A′B′C′.
What are the coordinates of the vertices of ∆A′B′C′ ?
Enter your answer by filling in the boxes.
Answer:
The coordinates of triangle A'B'C' are A'(-5,-1) B'(-1,-1) C'(-1,2)
Step-by-step explanation:
Translations
Given a point A(x,y), translating A by h units to the left will map it to A'(x-h,y).
The triangle ABC has coordinates: A(-2,-1) B(2,-1) C(2,2). Then translating the triangle left by h=3 units, the points are:
A'(-2-3,-1) B'(2-3,-1) C'(2-3,2)
A'(-5,-1) B'(-1,-1) C'(-1,2)
The coordinates of triangle A'B'C' are A'(-5,-1) B'(-1,-1) C'(-1,2)

All sweaters at a store are on sale at the same percent discount. A sweater that is regularly priced at $32.00 is on sale for $25.60. What is the sale price of a sweater regularly priced at $28.00?
Answer:
$22.40
Step-by-step explanation:
32 - 25.60 = 6.40
6.40/32 = 0.2
0.2 X 100 = 20%
100 - 20 = 80
28/100 X 80 = 22.40

Find the 77th term for each sequence(use the equation: an=a1+(n-1)d)
A)5,10,15,20,25...
B)17,14,11,8,5
Step-by-step explanation:
[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 5 \\ a2 = 10 \\ d = 5 \\ an = 5 + (n - 1)5 \\ an = 5n \\ a77 = 5 \times 77 = 385[/tex]
For B
[tex]a1 = 17 \\ a2 = 14 \\ d = 14 - 17 = - 3 \\ an = 17 + (n - 1) \times - 3 \\ an = 17 - 3n + 3 \\ an = 20 - 3n \\ a77 = 20 - 3 \times 77 \\ a77 = - 211[/tex]

The data set shows the ages of guests on a recent tour of a museum: 34, 18, 29, 60, 44, 51, 65, 68.
A. What is the five-number summary of the data? Show your work.
B. How could the museum curator use this information to improve sales at the gift shop?
I already did part A I just need help on part B
The five-number summary is
Min: 18 Max: 68 Median: 47.5
Q1: 31.5 Q3:62.5
Answer:
Step-by-step explanation:
Given the data:
34, 18, 29, 60, 44, 51, 65, 68.
Ordered data :
18, 29, 34, 44, 51, 60, 65, 68
The five number summary :
Sample size = 8
Minimum = 18
Lower quartile (Q1) = 1/4 (n+1) = 9/4 = 2.25
(2nd + 3rd term) / 2
= (29 + 34) / 2 = 31.5
Using calculator :
Median (Q2) = 47.5
Upper quartile (Q3) = 62.5
Maximum = 68
2.) With the information above, the museum curator could use this to guide their stock preference by stocking up gifts suitable for adults and youths, stockingbup with children's gift may be a bad options as visitors are atleast 18 years of age.

There are only red beads and green beads in a bag.
The ratio of the number of red beads to the number of green beads is 5 : 9
(a) What fraction of the beads are red?
There is a total of 84 beads in the bag.
(b) How many of the beads are green?
Susie is going to put some more beads in the bag.
There will still be only red beads and green beads in the bag.
Susie wants to have twice as many green beads as red beads in the bag.
(c) What beads should she put in the bag?
You must explain your answer
Answer:
(a) 5/14
(b) 54 beads
(c) 6 green beads
Step-by-step explanation:
(a) Find the total number of units for red and green beads.
5 + 9 = 14
Since red beads is 5, it is 5/14.
(b) Find the units for red and green beads altogether.
5 + 9 = 14
14 units = 84 beads
Find one unit.
1 unit = 84 ÷ 14 = 6 beads
Since green beads have 9 units, find how many beads there are in 9 units.
9 units = 6 x 9 = 54 beads
(c) As there are 54 green beads and Susie wants to have twice as much green beads as red beads, she have to find how many red beads there are first.
Since red beads have 5 units, find how many beads there are in 5 units.
5 units = 6 x 5 = 30 beads
After that, since she wants twice, she have to find x2 of 30 beads which are red.
30 x 2 = 60
After that, find the remaining amount of green beads needing to make x2 of 30.
60 - 54 = 6 beads (green)
Part(a),
5/14 of the beads are red.
Part(b),
There are 54 green beads in the bag.
Part(c),
Add 18 red beads and 36 green beads to the bag to get the desired ratio.
How to get the solution?(a) There are five times as many red beads as green beads, or a 5:9 ratio. Therefore, there are 9 green beads in the bag for every 5 red beads. Therefore, the fraction of the beads that are red can be expressed as:
5/(5+9) = 5/14
So, 5/14 of the beads are red.
(b) The bag contains 84 beads, and the proportion of red to green beads is 5:9. Let G equal the number of green beads and R equals the number of red beads. Next, we have:
R/G = 5/9
And we also know that:
R + G = 84
We can use the first equation to express R in terms of G:
R = (5/9)G
This results from substituting this into the second equation:
(5/9)G + G = 84
Simplifying:
(14/9)G = 84
G = (9/14) * 84 = 54
So there are 54 green beads in the bag.
(c) Let's assume that the bag currently contains G-green beads and R red beads. So that there are twice as many green beads as red beads, we wish to add a few more beads.
G = 2R
We also know that the total number of beads in the bag should be:
R + G + X = 84
Where X is the required number of beads. G = 2R is substituted into this equation to produce:
R + 2R + X = 84
3R + X = 84
Finding R and X numbers that meet both this equation and the prerequisite that G = 2R is necessary. One potential answer is:
R = 18, X = 30
This gives:
G = 2R = 36
And:
R + G + X = 18 + 36 + 30 = 84
Hence, to get the correct ratio, we can add 18 red beads and 36 green beads to the bag. There might be other workable alternatives as well, though.

The population of Laredo, Texas, was about 215,500 in 2007. It was about 123,000 in 1990. If we assume that the population growth is constant, write a linear equation with an integer slope to represent p, Laredo’s population t years after 1990.
The equation of population of Laredo, Texas is :
- [tex]p=\frac{92500}{17}t+123000[/tex]
"Population Growth"Given:
t = the number of years after 1990.So, for 1990, t = 0. So the coordinate is (0, 123000).For 2007, t = 17. So the coordinate is (17, 215500).Using point slope formula:
point slope= [tex]\frac{p-123000}{t-0point slope=\frac{215500-123000}{17-0}\\\frac{p-123000}{t}point slope=\frac{92500}{17}\\p-123000point slope=\frac{92500}{17}t\\ppoint slope=\frac{92500}{17}t+123000[/tex]Learn more about "population growth":

Find a value of M that will give you a system of equations with exactly one solution.
Y=6x+1
Y=mx+1
Given:
System of equations is
[tex]y=6x+1[/tex]
[tex]y=mx+1[/tex]
To find:
A value of M that will give you a system of equations with exactly one solution.
Solution:
A system of equation has exactly one solution if the graph of the equation is neither parallel nor coincident.
Slope of parallel lines are same. But in the given equations if slopes are same then both the system of equations have two same equations which represent coincident lines.
For one solution, [tex]m\neq 6[/tex].
So, the value of m can be any real number except 6 because for m=6.
Thus, [tex]m=R-{6}[/tex].
1 is a real number which is not equal to 6.
Therefore, one possible value of m is 1.
