shift the graph of y=x down 2 units
Answers
Answer:
shown in drawing attached
y=x-2
Step-by-step explanation:
Shift each point down by two. First plot y=x, then shift down by 2 for each point.
please give thanks :)
You have to subtract 2 from the y-coordinate to shift the graph of y = x down to 2 units.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
To shift the graph of y = x down 2 units, you can subtract 2 from the y-coordinate of each point on the graph.
This will be done by replacing y with y-2 in the equation, so the new equation would be y = x + (-2) which is y = x - 2
So the new equation for the graph will be y = x - 2
This will cause the graph to move down 2 units along the y-axis.

You want to buy some rice. An 8-ounce package costs $2.88. A 12-ounce package costs $4.56. A 26-ounce package costs $9.10. Which package is the best buy?
Answers
Divide cost by ounces. The lowest cost per ounce is the better buy.
2.88/8 = 0.36
4.56/12 = 0.38
9.10/26 = 0.35
The 26 ounce package is the better buy.
Answer:
The 26-ounce package is the best buy
Reasoning:
In order to figure out the best buy, you have to see the price-per-ounce in each option and figure out the one that costs the least. The way to do this is by dividing the decimal in the pricing by the number of ounces in the package. For example, 2.88/8 = 0.36
This tells us that the price-per-ounce in the 8-ounce package is 0.36
Repeat this process for each of the other two packages to find that
4.56/12 = 0.38 and 9.10/26 = 0.35
with this information, we can conclusively say that the 26-ounce package is the best buy, as it has the lowest price-per-ounce of all three of the packages.

3.142x + 2x = 25.71
5.142x = 25.71
x = 5
Step-by-step explanation:
Expression for Semicircle perimeter: xπ + 2x. (C)
Therefore x(π + 2) = 25.71 and x = 25.71 / (π + 2) = 5.

The ratio of the number of cars to dolls in a toy store is 3/20 . The ratio of the number of male dolls to the number of female dolls is 3:5 There are 500 female dolls. How many toys are there?
Answers
Answer:
800 dolls
Step-by-step explanation:
Step one:
given data
we are told that the ratio of the number of male dolls to the number of female dolls is 3:5 , i.e male dolls to female dolls is 3 to 5
given that there are 500 female dolls, let the number of male dolls be x
Step two:
3/5= x/500
cross multiply we have
3*500=5x
1500=5x
divide both sides by 5
x=1500/5
x=300
hence there are 300 male dolls
The total dolls is 300+500= 800 dolls
Given an inequality, what strategies can we use to determine where the boundary line is? Explain your strategies in detail.
4x+3y≥12
Answers
Answer:
Step-by-step explanation:
The strategy to determine the boundary line is that we need to remove the inequality sign and replace it with and equal to sign and then sketch the equation of the function which is
[tex]4x+3y=12[/tex]
to sketch the function we need the function's x-intercept which means the graphs crosses the x-axis at that specific point (x , 0) and y-intercept which means the graph crosses the y-axis at that specific point (0 , y).
Since both these points lie on line we can substitute it into the equation to find the x-y intercepts and hence sketch the line so here goes.
For x-intercept:
[tex]4x+3y=12\\4(x)+3(0)=12\\4x=12\\x=12/4\\x=3[/tex]
so the x-intercept is (3 , 0)
For y-intercept:
[tex]4x+3y=12\\4(0)+3(y)=12\\3y=12\\y=12/3\\y=4[/tex]
so the y-intercept is (0 , 4)
now we sketch these 2 points and draw a straight line joining both the points as shown in the image below.

Javier and Ebony track the number of steps they walk. Javier records a walk of 6000 steps in 50 minutes. Ebony describes her step rate with the equation y=118, where y is the number of steps and x is the number of minutes she walks. This week, Javier and Ebony each walk a total of 5 hours. Who walks more steps?
Answers
Answer:
Javier walks more steps than ebony given the same minutes
Step-by-step explanation:
Javier records a walk of 6000 steps in 50 minutes.
Ebony describes her step rate with the equation y=118x
Where,
y = number of steps
x = number of minutes she walks
Javier and Ebony each walk a total of 5 hours. Who walks more steps?
5 hours = 5 × 60 minutes
= 300 minutes
Javier records a walk of 6000 steps in 50 minutes.
6000 : 50 minutes = x : 300 minutes
6000/50 = x / 300
Cross product
6000 * 300 = 50 * x
1,800,000 = 50x
x = 1,800,000 / 50
= 36,000
x = 36,000
Javier walks 36,000 steps
Ebony describes her step rate with the equation y = 118x
x = 300 minutes
y = 118(300)
= 35,400
y = 35,400
Ebony walks 35,400 steps
Therefore,
Javier walks more steps than ebony given the same minutes
