Complete Question:
Alicia is writing the program for a video game. For one part of the game she uses the rule (x,y)->(x-3,y+4) to move points on the screen.
A) what output does the rule give when the input is (-6,0)?
B)What output does the rule give when the input is (3,-4)?
C) Is the rule a function? Explain why it is or why it is not
Answer:
a. The output is (-9,4)
b. The output is (0,0)
c. See Explanation
Step-by-step explanation:
Given
Rule: (x,y)->(x - 3, y + 4)
Solving (a):
Inputs:
[tex]x = -6[/tex]
[tex]y = 0[/tex]
The outputs is as follows;
[tex]x => x - 3[/tex]
[tex]x => -6 - 3[/tex]
[tex]x => -9[/tex]
[tex]y=> y + 4[/tex]
[tex]y=> 0 + 4[/tex]
[tex]y=> 4[/tex]
Hence:
The output is (-9,4)
Solving (b):
Inputs:
[tex]x = 3[/tex]
[tex]y = -4[/tex]
The outputs is as follows;
[tex]x => x - 3[/tex]
[tex]x=>3-3[/tex]
[tex]x = 0[/tex]
[tex]y=> y + 4[/tex]
[tex]y=>-4+4[/tex]
[tex]y=>0[/tex]
Hence:
The output is (0,0)
Solving (c):
The function is a rule and the rule is that:
It shifts the graph left by 3 units and up by 4 units
what is 11x11 ????????????????????
Answer:
121
Step-by-step explanation:
11 x 11
this is what goes on in my head you don't have to this but this is what i do
10 x 10 = 100
10 x 1 = 10
1 x 10 = 10
1 x 1 = 1
100 + 10 + 10 + 1 = 121
The product of the numbers 11 with 11 is 121.
Given are the numbers 11 and 11.
We have to find the product of these numbers.
This can be found in various ways.
We can study the perfect squares from 1 to 20 to know it fast.
Else you can use normal multiplication.
Or another method is,
Split both 11 as 10 and 1 and then find the product with each.
10 × 10 = 100
Then find 10 with 1.
10 × 1 = 10
Then find 1 with 10.
1 × 10 = 10
Then find 1 with 1.
1 × 1 = 1
Total is 100 + 10 + 10 + 1 = 121
Hence the number is 121.

6 y - 8
Step-by-step explanation:
Simplify the following:
8 y - 2 (y + 4)
Hint: | Distribute -2 over y + 4.
-2 (y + 4) = -2 y - 8:
8 y + -2 y - 8
Hint: | Group like terms in 8 y - 2 y - 8.
Grouping like terms, 8 y - 2 y - 8 = (8 y - 2 y) - 8:
(8 y - 2 y) - 8
Hint: | Combine like terms in 8 y - 2 y.
8 y - 2 y = 6 y:
6 y - 8
Hint: | Factor out the greatest common divisor of the coefficients of 6 y - 8.

Gwendolyn draws a hotdog on graph paper using the scale shown below. The hotdog has a length of 9
units in the drawing.
Scale:
10 cm
length
A
What is the length, in cm, of the actual hotdog?
cm
The length of the actual hotdog comes to be 15cms.
What is a scale factor?A scale factor is a ratio between corresponding measurements of an object and a representation of that object.
From the diagram
6 units = 10cm
So, 1 unit =10/6 cm
The length of the hotdog shown in the graph = 9 units
So, 9 units = 9*(10/6)
9 units = 15cms
So, the actual length of the hotdog =15cms
Thus, the length of the actual hotdog comes to be 15cms.

The output of a function is 5 more than 2 times the input. Find the input when the output is 17.
Answer:
The input when the output is 17 is x=6.
Step-by-step explanation:
Functions
Assume the input is called x and the output is the function f(x). Two times the input is 2x. 5 more than that is 2x+5.
Knowing the output of the function is 5 more than 2 times the input, we can write the function as:
f(x)=2x+5
Now find the input x when the output is 17:
17=2x+5
Swap sides of the equation:
2x+5=17
Subtract 5:
2x=17-5=12
Divide by 2:
x=12/6=6
The input when the output is 17 is x=6.

Which of the following is a correct next step to solve the equation? (1 point)
X-4 = -7
x+4=-7
x + 4 = 7
-x-4= 7
Answer:
x-4 = 7 , x-4 = -7

IX - 4l+ 1 = 8
Subtract 1 from each side
IX - 4l = 8-1
IX - 4l = 7

.A bucket is filled with 1 3/4 gallons of water. The bucket has a small hole and 1/4 gallon leaks out every hour. How many hours will it take for the bucket to be completely empty? What must you do to the mixed number in order to solve this problem?
Given :
A bucket is filled with 1 3/4 gallons of water.
The bucket has a small hole and 1/4 gallon leaks out every hour.
To Find :
How many hours will it take for the bucket to be completely empty.
Solution :
We know , mixed fraction of form a p/q is given by :
[tex]a\ p/q = \dfrac{(a\times q)+p}{q}[/tex]
So, 1 3/4 = 7/4 .
Let, after t hours bucket is empty.
[tex]\dfrac{7}{4}-\dfrac{1}{4}t = 0\\\\t = 7\ hour[/tex]
Therefore, it takes 7 hours for the bucket to be completely empty.
Hence, this is the required solution.

Plz HELP with a and b I WILL MARK AS A BRAINLIEST IF YOU CAN HELP ME WITH BOTH A AND B PLZZ
Answer:
a) x = 60
b) b = 110
Step-by-step explanation:
A)
2x and 120 are vertical angles.
vertical angles are equivalent.
2x = 120
divide both sides of the equation by 2
2x/2 = 120/2
x = 120/2
x = 60
B)
b + 20 and 130 are on the same side of the line
(I forgot what the math term is, but they're also equal)
b + 20 = 130
subtract 20 from both sides of the equation
b + 20 - 20 = 130 - 20
b = 130 - 20
b = 110
