Answer:
Well, there are 4 quadratic spots on the graph. A(1,3) would be in the top right. B(0,-3) would be on the line on the bottom half of the graph. C(-4,-2) would be in the left bottom half of the graph. and D(-11/4,2) would be in the top right. Connect the dots and just say the shape it makes.
Step-by-step explanation:
What is the image of (2, 1) after a dilation by a scale factor of 4 centered at the
origin?
HELP
Answer:
The image of the point is (8, 4)
Step-by-step explanation:
If the point (x, y) dilated by a scale factor k centered at the origin, then its image is (kx, ky)
Let us solve the question
∵ The point is (2, 1)
∴ x = 2 and y = 1
∵ The point dilated by a scale factor of 4 centered at the origin
∴ k = 4
→ By using the rule above multiply each coordinate of the point by 4
∵ The image of the point is (kx, ky)
∵ kx = 4 × 2
∴ kx = 8
∵ ky = 4 × 1
∴ ky = 4
∴ The image of the point is (8, 4)
Challenge The numbers of home runs a baseball player hits during spring training and during the regular season for four years are shown. Decide if the relationship between home runs hit in spring training and during the regular season is proportional. If the table represents a proportional relationship, find how many home runs are hit during the regular season if the player hit 3 during spring training
Answer:
12
Step-by-step explanation:
Key word: Most likely
First try to find the constant of proportionality
8/2= 4
4/4= 1
20/5=4
24/6=4
Since it says most likely we would say the constant of proportionality is 4.
Since they are asking for 3 homes runs we will do 3 times 4
[tex]3[/tex]×[tex]4=12[/tex]
The player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.
What is constant of proportionality?The constant of proportionality is the ratio between two directly proportional quantities.
Two quantities are directly proportional when they increase and decrease at the same rate.
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Finding the constant of proportionality :-
8/2= 4
4/16= 4
20/5=4
24/6=4
Since, the constant of proportionality is 4.
And, they are asking for 3 homes runs we will do 3 times 4
Therefore, 3 x 4 = 12
Hence, the player will hit 12 home runs are hit during the regular season if the player hit 3 during spring training.

what is the equation of a line perpendicular to 2x-3y=6 and passes through the point (6,-1) ?
Answer:
y=-3/2x+8
Step-by-step explanation:
Alright so first we need to convert this equation to Y=mx+b form.
We get y=2/3x-2
In order for it to be perpendicular, we must use -3/2 as the slope.
y=-3/2x+b
Next we need to find the y-intercept of this
Plug in 6 for x and -1 for y and solve for b
b=8
Hope this helps :-)
Using the slope formula, find the slope of the line through the given points ( 9, 4 ) and ( 4, 4 )

An asteroid is 10^{8} miles away from earth, and it is traveling at a speed of 10^{5} miles per day.
How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
1,000 is equal to 10^3

Answer: Kiran is correct
Step-by-step explanation: kiran would be correct because if they were to double the length of the rectangle then the corner to corner length would also double. Sure mai is right when she says that the diagonal length is longer then to two side lengths but that doesn't change the fact that it would only double and nothing more.

Suzy has a collection of quarters and dimes. Together she has 34 coins worth $6.40. How many quarters and how many dimes does Suzy have?
Please show your work :)
Answer:
Quarters = 20
Dimes = 14
Step-by-step explanation:
Dime = x = 10 cent = $0.1
Quarter = y = 25 cent = $0.25
x + y = 34 - - - (1)
0.1x + 0.25y = 6.40 - - - - (2)
From (1)
x = 34 - y
0.1(34 - y) + 0.25y = 6.40
3.4 - 0.1y + 0.25y = 6.40
3.4 + 0.15y = 6.40
0.15y = 6.40 - 3.40
0.15y = 3
y = 3 / 0.15
y = 20
x = 34 - y
x = 34 - 20
x = 14
Quarters = 20
Dimes = 14

8/11 x (5/9 - 1/6) ÷ 1 5/9
Answer:
28/165
Step-by-step explanation:
You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.
You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).
The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.
The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.

P'(3, 7), e'(-6, 7), R' (0,7)
P'(-3, 13), e' (3, 13), R'(-3, 16)
Answer:
We have the answer as:
P'(0, 13), O'(-9, 13), R'(-3, 16)
Step-by-step explanation:
Here, we want to find the coordinates of the image after applying the transformation rule to the pre-image
what the transformation rule is saying is that we subtract 3 from the x-coordinate and add 7 to the y-coordinate
mathematically, we have these as follows;
P’ = (3-3, 6 + 7) = (0,13)
Q’ = (-6-3, 6 + 7) = (-9,13)
R’ ( 0-3, 9 + 7) = (-3, 16)
How are the functions
f(x) = 16* and
19(x) = 161/2
related?
Answer:
F(x) = 16^x = 8^2x
g(x) = 16^1/2x = 8^x
So you can see the relationship. They are all of the type a^bx form, with same base of a, f(x) will have larger increasing rate.
