A down arrow is drawn with its tip at (2, 0). Then it undergoes a translation described bythe directed line segment (−3, 1). What direction is the arrow pointing?
Answer:
down
Step-by-step explanation:
In mathematics a when dealing with graphs a translation is basically just moving points left/right and up/down but it does not change the shape of the original figure in any way just moves its position. In this scenario, the down arrow's tip will be moved from point (2,0) to (-3,1) but the arrow will still be the same size and still be pointing downward.

On a coordinate grid, point P is at (5, 2) and point R is at (−3, −4). Points Q and S are a reflection of both points across the x-axis. What are the coordinates of Q and S?
Q(−5, 2), S(3, −4)
Q(−5, −2), S(3, 4)
Q(5, −2), S(−3, 4)
Q(−5, 2), S(−3, 4)
Answer:
c) Q( 5, -2) , S(-3,4)
P( 5,2) → Q( 5, -2)
Q(-3,-4)→ S(-3,4))
Step-by-step explanation:
Explanation:-
Given points are P( 5,2) and Q(-3,-4)
Points P and R reflection across the x-axis then the co-ordinate point is transformed to (x,y)→ (x,-y)
P( 5,2) → Q( 5, -2)
Q(-3,-4)→ S(-3,-(-4))
Q(-3,-4)→ S(-3,4))

John has $65 in his piggy bank. He wants to buy a new gaming
system for $257. If he saves $!2 per day, how many days will it be
before he can buy his new gaming system?
John need to save 2 dollars for 96 days
Answer:
96 days
Step-by-step explanation:
Since he already has $65 we will subtract this from $257. This leaves us with $192 to earn. Dividing $192 by 2 (Because John is getting $2 per day) will result in 96.

In AXYZ, the angle measures are in the ratio 2:4:6. What are the measures of the angles?
Answer:
Please check the explanation.
Step-by-step explanation:
Given that the measures of the Angles of the triangle ΔXYZ are in the ratio 2:4:6.
As the angles are in the proportion 2:4:6. Thus, the measure of the angles will have the same scale factor x.Also, the sum of the measure of angles in a triangle is 180°.
so
2x + 4x + 6x = 180
Add similar elements: 2x + 4x + 6x = 12x
12x = 180
Divide both sides by 12
12x/12 = 180/12
Simplify
x = 15
Therefore, the measure of the angles of a triangle will be:
2x = 2(15) = 30
4x = 4(15) = 60
6x = 6(15) = 90
Verification:
30 + 60 + 90 = 180
180 = 180

Answer:
FC = 27, QC = 18
Step-by-step explanation:
The centroid Q is [tex]\frac{1}{3}[/tex] the way along CF , therefore, QF is half as long as CQ
Given FQ = 9, then
QC = 2 × 9 = 18
FC = FQ + QC = 9 + 18 = 27

Stephanie gets on her bike and rides for 3 hours. She rides at an average speed of 12.5 km per
hour.
- What distance did Stephanie travel?
Stephanie rode the bike with an speed of 37.5 km. If she ride the bude and the average speed for her is 12.5 km per hour, multiply 12.5 with how much hour to get the answer. 12.5x3=37.5. This means that Stephanime rode her bike and got a speed of 37.5 km.
Write an equation for the line with a y-intercept of 5
that is perpendicular to the line with equation
y=-3x+2.
Answer:
y = -1/3 x + 5
Step-by-step explanation:
The general equation is y = mx + b
You are told that the y intercept is 5. The point is (0,5)
So far the general equation looks like y = mx + 5
Now we have to find m
The given slope of y = 3x + 2 is 3.
The slope is whatever number is in front of the x
Use this formula for the vertical slope
m * m1 = - 1
m1 = 3
3*m = - 1 Divide by 3
m = -1/3
So the answer you want is y = -1/3 x + 5

Suzanne is putting a fence around her rectangular garden. The length of the garden, x, is 4 feet more than the width. The perimeter of the garden is 32 feet. Write an equation to find the length of the garden.
Enter the correct answer in the box.
Answer:
Length=10 feet
Width=6 feet
Step-by-step explanation:
Let width (W) of the garden is x feet
Then Length=L=4+x feet
Perimeter=P=2(W + L)
P=2(x+x+4)
32=4x+8
4x=32-8
x=24/4=6 feet
W=6 feet
L=10 feet

Last summer, an ice cream shop sold a small ice cream for $1.25 and a large ice cream for $3.75. The ice cream shop decided to raise its prices this summer while keeping them proportional to last year's prices. Which of the following answer choices are possible prices for the ice cream this summer?
A.small ice cream: $2.50 , large ice cream: $5.00
B. small ice cream: $1.50, large ice cream: $4.50
C.small ice cream: $2.00, large ice cream: $4.25
D. small ice cream: $1.80, large ice cream: $7.20
Answer:C
Step-by-step explanation:
keeping proportional and thats the only answer where the difference is still $2.25
Answer:
Correct choice: B
Step-by-step explanation:
Proportions
The ice cream shop sold small ice creams for $1.25 each and large ice creams for $3.75 each.
This summer the prices will be raised at the same proportion. If x is the new price for small ice creams and y is the new price for large ice creams, then it should be satisfied:
[tex]\frac{1.25}{x}=\frac{3.75}{y}[/tex]
Let's test each option:
A.
[tex]\frac{1.25}{2.50}=0.5[/tex]
[tex]\frac{3.75}{5.00}=0.75[/tex]
B.
[tex]\frac{1.25}{1.50}=0.83[/tex]
[tex]\frac{3.75}{4.50}=0.83[/tex]
C.
[tex]\frac{1.25}{2.00}=0.625[/tex]
[tex]\frac{3.75}{4.25}=0.88[/tex]
D.
[tex]\frac{1.25}{1.80}=0.694[/tex]
[tex]\frac{3.75}{7.20}=0.52[/tex]

LaTeX: \Delta QRS\cong\Delta TUV,\:QS=3v+2,Δ Q R S ≅ Δ T U V , Q S = 3 v + 2 , and LaTeX: TV=7v-6,T V = 7 v − 6 , enter the lengths of QS
Answer:
The length of QS = 8
Step-by-step explanation:
From the above question:
Δ Q R S ≅ Δ T U V
Q S = 3 v + 2 , and T V = 7 v − 6 , enter the lengths of QS
Hence:
Step 1
We solve for v
QS = TV
3v + 2 = 7v - 6
Collect like ters
2 + 6 = 7v - 3v
8 = 4v
v = 8/4
v = 2
Step 2
Solving for Q S
Q S = 3 v + 2
v = 2
QS = 3(2) + 2
QS = 6 + 2
QS = 8
The length of QS = 8

If –3(y - 1) = 9, find the value of 1/2y
Answer:
The value of [tex]\frac{1}{2}y[/tex] is -1
Step-by-step explanation:
Equations
We have the equation:
[tex]-3(y - 1) = 9[/tex]
It's required to find
[tex]\frac{1}{2}y[/tex]
Let's solve the equation. Dividing by -3:
[tex]y - 1 = \frac{9}{-3}= -3[/tex]
Adding 1:
[tex]y=-3+1=-2[/tex]
Since y=-2, then y/2=-1
The value of [tex]\frac{1}{2}y[/tex] is -1
