Answer: the rate is (1/8) paintings per week
Step-by-step explanation:
We usually define the rate as the amount of work done in some unit of time.
In this case, we know that the artist does 1/4 of a painting in 2 weeks, then the rate can be written as:
(1/4)/2 paintings/week = (1/8) paintings/week.
This means that the rate is (1/8) paintings per week, this is the weekly rate at which she works.

32 jelly beans was share with 8 students how many each students get
please answer it i`ll give you brainiest
Answer:
4 students would get jellybeans because 32 divided by 4 would be 8 and 8 times 4 is 32. hope this helps! :D
Step-by-step explanation:
brainliest plz?
If 32 jelly beans were shared with 8 students each will get 4 jelly beans.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, 32 jelly beans were shared with 8 students.
The no. of jelly beans each student will get can be obtained by dividing the total no. of jelly beans divided by the total no. of students which is,
= (32/8) jellybeans each.
= 4 jelly beans each.

How can I find the systems of linear inequalities
Match each function with the expression representing Its Inverse function.
1. g(x)= -0.5 x
2. h(x)= 4 x
3. y= x - 4
4. f(x)= x/2
5. k(x) = x
6. p(x) = x+4
Answer:
Step-by-step explanation:
1). g(x) = -0.5x
Equation form of the given function is,
y = -0.5x
Interchange x and y,
x = -0.5y
Solve for y,
y = [tex]-\frac{x}{0.5}[/tex]
y = -2x
Inverse function will be,
[tex]g^{-1}x=-2x[/tex]
2). h(x) = 4x
Equation form of the function will be,
y = 4x
Interchange x and y,
x = 4y
Solve for y,
y = [tex]\frac{x}{4}[/tex]
Inverse function will be,
[tex]h^{-1}(x)=0.25x[/tex]
3). y = x - 4
Interchange x and y,
x = y - 4
Solve for y,
y = x + 4
Therefore, inverse of the linear equation is,
y = x + 4
4). f(x) = [tex]\frac{x}{2}[/tex]
Equation form of the function will be,
y = [tex]\frac{x}{2}[/tex]= x
Interchange x and y,
x = [tex]\frac{y}{2}[/tex]
Solve for y,
y = 2x
Therefore, inverse function will be,
[tex]f^{-1}(x)=2x[/tex]
5). k(x) = x
Equation form of the function will be,
y = x
Interchange x and y,
x = y
Solve for y,
y = x
Inverse of the function 'f' will be,
[tex]k^{-1}(x) =x[/tex]
6). p(x) = x + 4
Equation form of the function will be,
y = x + 4
Interchange x and y,
x = y + 4
Solve for y,
y = x - 4
Inverse of the function 'p' will be,
[tex]p^{-1}(x)=x - 4[/tex]
Question 5 of 10
If f(x) = 4x2 + 1 and g(x) = x2 – 5, find (f+ g)(x).
O A. 3x2 + 6
B. 5x2 - 6
C. 3x2 - 4
D. 5x2 - 4
Step-by-step explanation:
(f + g)(x) = f(x) + g(x) = (4x² + 1) + (x² - 5) = 5x² - 4. (D)
Answer:
D. 5x^2-4
Step-by-step explanation:
We are asked to find (f+g)(x), which is really just the sum of the two functions.
(f+g)(x)=f(x)+g(x)
We know the the functions are:
• f(x)= 4x^2+1
• g(x)=x^2-5
Substitute the functions in.
(f+g)(x)=(4x^2+1)+(x^2-5)
Add the functions by combining like terms. For this equation, the like terms are those with x^2 and the constants.
(f+g)(x)= (4x^2+x^2)+(1-5)
Add the terms with x^2
(f+g)(x)=(5x^2)+(1-5)
Add the constants or terms without variables.
(f+g)(x)=(5x^2)+(-4) = 5x^2-4
The sum of the functions is D. 5x^2-4
Solve for x:
8x – 3 = 5 (2x + 1)
A. x= -4
B. x= -2

Answer:
x=-4
Step-by-step explanation:
Answer: A
Step-by-step explanation: Simplify 5(2x+1) into 10x+5. bring it to the other side; -2x-8=0. -2x=8 divide 8 by -2 to get x alone. x=-4

C
{–4, 0, 2, 7}
D
{–4, 0, 1, 2, 7}
Answer:
The range of the relation is:

Therefore, option B is true.
Step-by-step explanation:
Given the relation
Input Output
-4 1
0 7
2 2
7 7
Determining the domain:
We know that the domain of relation consists of all the inputs or x-coordiantes of the ordered pairs.Thus, the domain of the relation is:
Domain R = {-4, 0, 2, 7}
Determining the range:
We know that the range of relation consists of all the outputs or y-coordiantes of the ordered pairs.Thus, the range of the relation is:
Range R = {1, 2, 7}
Please note that the duplicated elements in the domain or the range of the function are written only once.Therefore, option B is true.

[tex]The \: slope \: is \: \frac{7}{3} .[/tex]
Step-by-step explanation:
To find the slope, we have to turn the equation into the slope-intercept form which is:
[tex]y = mx + b[/tex]
The slope is the m in that form.
we will solve for y.
[tex]7x - 3y = 21 \\ \frac{- 7x \: \: \: \: \: \: = - 7x}{ - 3y = - 7x + 21} \\ \\ \frac{ - 3y}{ - 3} = \frac{ - 7x + 21}{ - 3} \\ y = \frac{7}{3} x - 7[/tex]
Answer:
Step-by-step explanation:
-3y = -7x + 21
3y = 7x - 21
y = 7/3x - 7
slope is 7/3

A right triangle has one angle that measures 24°. What is the measure of the other acute angle?
Answer:
66 degrees
Step-by-step explanation:
90+24=114
180-114=66
Answer:
66 degrees
Step-by-step explanation:
a right triangle must have a 90 degree angle and our other angle is 24. we also know that the sum of all the angles must be 180. 90+24=114
180-114 is 66

exactly twice as many shirts as jeans, how many pairs of jeans can Jess buy without exceeding $500?
Answer:
167 pairs
Step-by-step explanation:
Represent jeans with J and shirts with S
[tex]S = 2J[/tex]
[tex]Amount = \$500[/tex] --- Maximum
Required
Determine the number of pair of jeans he can buy
To represent as an inequality, we have:
[tex]S + J \leq Amount[/tex]
[tex]S + J \leq 500[/tex]
Substitute 2J for S
[tex]2J + J \leq 500[/tex]
[tex]3J \leq 500[/tex]
Divide through by 3
[tex]J \leq 500/3[/tex]
[tex]J \leq 167[/tex]
Hence, without exceeding $500, Jess can buy 167 pairs of jeans

y^3 + 27 = 0
Answer:
-31.5(1 + i√3)1.5(1 - i√3)Step-by-step explanation:
y³ + 27 = 0(y + 3)(y² - 3y + 9) = 01. y + 3 = 0 ⇒
y = -32. y² - 3y + 9 = 0
y = (3 ±√(3² -4*9))/2y = (3 ± √-27)/2y = (3 ± i√27)/2y = 3/2(1 ± i√3)y = 1.5(1 ± i√3)Answer:

If Arron's boat travels 9 mph and the river runs 4 miles mph in still water.how long will it take to travel 18 miles upstream
Answer: It will take Aaron's boat 3³/₅ hours to travel 18 miles upstream.
That is 3.6 hours or 3 hours and 36 minutes.
Step-by-step explanation:
Traveling upstream, the boat's speed will be reduced by the speed of the river current.
9 - 4 = 5mph
18mi/5mph = 3.6 hours 0r 3³/₅ hours
