Answer: you are going to make one point at 0,5. then another in between -1 and -2, so that it shows -5/4 on the x-axis.
Step-by-step explanation:
Consider the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}. What is the range of the function?
Answer: {-4,-3,-2,2} or c on the test nav assessment Question 7.
Step-by-step explanation:
It asks for the range. Range is your output. Which is your y. Plug in your domain (which is your x or input).
Your domain is {-2,0,2,10}
h(-2)=1/2(-2)-3=-4
h(0)=1/2(-0)-3=-3
h(2)=1/2(2)-3=-2
h(10)=1/2(10)-3=2
Actually B. If it’s asking for the restricted domain. Because a restricted domain, is a domain with a denominator. And this doesn’t have a denominator. So it would be all real numbers.
The range of function is {-4, -3, -2, 2} if the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We are assuming the function is:
[tex]\rm h(x) =\dfrac{1}{2}x-3[/tex]
The domain of the function: {-2,0,2,10}
Find the value of the function at points -2, 0, 2, and 10:
h(-2) = 1/2(-2)-3 = -4
h(0) = 1/2(-0)-3 = -3
h(2) = 1/2(2)-3 = -2
h(10) = 1/2(10)-3 = 2
So the range of function will be {-4, -3, -2, 2}
Thus, the range of function is {-4, -3, -2, 2} if the function h(x)=1/2x-3 with a restricted domain of {-2,0,2,10}.

Luke bought 2 used games at the game store if each used game cost $7.85 and he paid with a twenty dollar bill how much change should get back
Answer:
$4.30
Step-by-step explanation:
First, find the cost of both games by multiplying the price by 2:
7.85(2)
= 15.7
Then, to find his change, subtract this from 20:
20 - 15.7
= 4.3
So, Luke should get $4.30 back in change.

Dylan has a bank that sorts coins as they are dropped in. The panel on the front shows that there is a value of $17.55 inside of the bank.
Dylan only collects dimes and quarters. If the number of quarters he has is nine less than twice the amount of dimes, write an equation that can be used to model this equation.
Answer: .10d+.25q=17.50
d+q=90

Priya has completed 9 exam questions. This is 60% of the questions on the exam.
Answer:
Your answer is 15, 100% of the exam is 15 questions.
Step-by-step explanation:
60% x ? = 9
We need to do 9 divided by 60%
Which is actually 9 divided by 60/100.
Which is equal to; (100 x 9) divided by 6.
Which is then 900 divided by 60 which equals 15.
Answer: 15

3x – 9y = 9 and the same y-intercept as 8x – 2y = 6.
Answer:
y= 1/3x -3
Step-by-step explanation:
For the y-int for 8x-2y=6 is (0, -3).
For the slope of 3x-9y=9 is 1/3.

Beach Cruises prints brochures and fliers to advertise their dolphin watching tours. To print, the brochure requires three pages while the flier requires two. They are limited to 500 sheets of paper, but need to print at least 80 brochures and 100 fliers. Each brochure cost 10 cents to print and each flier cost 6 cents to print. How many of each should their print to minimize their cost? Include: Constraints (inequalities), shaded graph, feasible region, labeled vertices, Objective Function, Max/Min

find the amount of x. 2x+4=3x-10
Answer:
x=14
Step-by-step explanation:
You want to get x by itself on one side so you start by canceling the smaller x: 2x. You do this by subtracting 2x from both sides. You should have 4=x-10. After this, you want to cancel the -10 to get x by itself. To do this, you have to add 10 on both sides. You should have x=14. Lmk if this helps!
Answer: x=14
Step-by-step explanation:
2x+-3x=-4-10
-1x=14
X=14

Based on this scatterplot, if Carley runs in a 4-kilometer race and she maintains the same pace, how many minutes will it take her to run 4 kilometers?
The question is incomplete, the complete question is;
Based on the graph, if Carley runs in a 4- kilometer race and she maintains the same pace, how many minutes will it take her to run 4 kilometers?
A 50 minutes
B 45 minutes
C 35 minutes
D 20 minutes
Answer:
C 35 minutes
Step-by-step explanation:
If we look at the scatter plot closely, we can trace the distance of 4 Km on the vertical axis down to its matching point on the horizontal axis.
If this is done correctly, you will discover that the point on the time axis corresponding to the 4 Km distance on the vertical (distance) axis is 35 minutes (the point lies mid-way between 30 minutes and 40 minutes points on the horizontal axis).
Therefore, it will take Carey 35 minutes to run 4 Kilometres according to the scatter plot.
Answer:35 mins

D) 12
Answer:
i think it is A) 10
Step-by-step explanation:
Answer:
D. 12
Step-by-step explanation:
The middle line is two times shorter so:
x - 2 = 2(2x - 19)
simplify
x - 2 = 4x - 38
subtract 4x from both sides
-3x - 2 = -38
add 2 to both sides
-3x = -36
divide both sides by -3
x = 12

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.
2. Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
4. Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.
5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Let y= 2t + 5 be a linear function representing the distance, in feet, from home for an ant t minutes after starting out from a location near its home. What does the number 2 represent in this function?
Answer:
2 represents the slope
Step-by-step explanation:
Given the linear function representing the distance, in feet, from home for an ant t minutes after starting out from a location near its home expressed as
y = 2t + 5. This function is a linear function of the form y = mx+c where;
m is the slope (change in y with respect to x)
c is the intercept
Comparing this standard equation to y = 2t + 5, we will see that 2 represents the slope m which is change in the distance covered in feet with respect to the time taken
Does anyone know the correct choice for this question? If its correct ill mark you as the best answer choice!
Answer:
A
Step-by-step explanation:
The slope is positive. Also, using the rise/run method, I found that the slope is 3. The b is 4 because the line crosses the y axis at 4.
