We conclude that the range of the function will be:
R = {5, 17, 29}
Step-by-step explanation:
Given
Given the function
f(x) = 6x-1
Given the domain
D = {0, 3, 5}
To Determine:
The range R = ?
We know that range of the function consists of all the y-values for the x-values in the domain of the function.
so substituting the values of x = 0, 3, and 5 in the function to determine the corresponding y-values.
Plug in x = 0
y = 6x-1
y = 6(0) - 1 = 6-1 = 5
Plug in x = 3
y = 6x-1
y = 6(3) - 1 = 18-1 = 17
Plug in x = 5
y = 6x-1
y = 6(5) - 1 = 30-1 = 29
Now, combine all the determined y-values which are 5, 17, and 29.
Therefore, we conclude that the range of the function will be:
R = {5, 17, 29}
Alina bought an ice cream cone for $3. Her 4- ounce scope of ice cream is melting at rate of 0.5 ounces per minutes. Write an equation to represent the amount of ice cream left after x minutes.
Answers
Answer:
y=4-0.5x
Step-by-step explanation:
Step one:
given data
Alina bought an ice cream cone for $3
the weight of the ice cream is 4 ounce
the rate of melting is 0.5 ounce per minute
let the number of minutes taken for the ice cream to melt be x
and the weight after x minutes be y
Step two:
Hence the expression for the situation after x minutes is

What is the sum of the next two numbers in the pattern 169,120,84,59,43,_,_
Answers
Answer:
64
Step-by-step explanation:
Here, we want to know the sum of the next two terms
We need to get the pattern first
The difference between the first two numbers is 49 (7^2)
next two is 36 (6^2)
next two is 25 (5^2)
next two is 16 (4^2)
next two will be 3^2 = 43-9 = 34
next will be 2^2 = 34-4 = 30
So the sum here is 30 + 34 = 64

Carlos's restaurant check is for $24.50. If he wants to add a 17% tip, what total amount should he pay?
Answers
Second, you need to find out what 17% of your $24.50 meal cost is.This is always done by multiplying 0.17 by $24.50
0.17 x $24.50=$4.16.
So, the amount of tip you are going to leave is $4.16.
This makes the total cost of your meal (to write on your charge slip or other payment)
$24.50 + $4.16 = $28.67.

Graph two more functions in the same family
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the slope-intercept of the line equation is
[tex]y = mx + b[/tex]
where m is the slope and b is the y-intercept
Please note that a linear equation contains no powers of x besides.
For example, the equation of the form
y = 2x+3
has the slope m = 2 and y-intercept b = 3
The graph is shown below.
Let us graph two more functions of the same family by changing the parameter of y-intercept b.
Graphing y = 2x+5
y = 2x + 5
has same slope m = 2. But, the y-intercept b = 5
The graph of y = 2x+5 is attached below.
Graphing y = 2x+7
y = 2x + 7
has same slope m = 2. But, the y-intercept b = 7
The graph of y = 2x+7 is attached below.
Thus, we would have the following graphs of the family of linear functions.
y = 2x+3y = 2x + 5y = 2x + 7Please notice that all the functions have the same slope m = 2. Thus, all the lines would be parallel.
Thus, from the graph, it is clear that:
The red line represents the function y = 2x+3 with the y-intercept (0, 3)The blue line represents the function y = 2x+5 with the y-intercept (0, 5)The green line represents the function y = 2x+7 with the y-intercept (0, 7)The graph is attached below.

the image of point A under a 90° rotation about the origin is A'(10, -4). What are the coordinates of point A?
Answers
Given:
The image of point A under a 90° rotation about the origin is A'(10, -4).
To find:
The coordinates of point A.
Solution:
90° rotation about the origin means the figure is rotated 90° counterclockwise about the origin and the rule of rotation is
[tex](x,y)\to (-y,x)[/tex]
Let the coordinates of A are (a,b).
[tex]A(a,b)\to A'(-b,a)[/tex]
The image of point A under a 90° rotation about the origin is A'(10, -4).
[tex]A'(-b,a)=A'(10,-4)[/tex]
On comparing both sides, we get
[tex]-b=10\Rightarrow b=-10[/tex]
[tex]a=-4[/tex]
Therefore, the coordinates of point A are (-4,-10).

Answers
Step-by-step explanation:
total profit or income =640+160=800the # means that the answer is ready in my openion i think
Step-by-step explanation:
30÷100×640=192
total income =160+192
=352
weekly sales=?(x)
wage=640
so...
x×0.3+160=640
0.3x=640-160
0.3x=480
x=480÷0.3
x=1600
the weekly sales is 1600

Zara has forgotten her 4-digit PIN code.
She knows the first digit is a factor of 10 and the 4 digits make a number divisible by 2.
How many different sets of 4 digits could it be?
Answers
Answer:
1500
Step-by-step explanation:
we can write the 4-digit PIN as ABCD
A = factor of 10 so,
A = 1, 2 ,5 (3 possible number or we can write n(A) = 3
B and C are number from 0 - 9 so each have 10 possible number n(B) = 10 and n(C) = 10
D makes the whole number cannbe divide by 2. it means that D must even number 2,4,6,8 or 0. so there are 5 possible number n(D) = 5
so to find how many different sets we just multiply all possible number
n(A) x n(B) x n(C) x n(D)
3 x 10 x 10 x 5 = 1500 different sets
