Help me graph this plssss!!! I’d really appreciate it!
Answer:
Okay so, first put a dot on the number three. Next, go down one and over two from that spot (2, 2) and so on.
Step-by-step explanation:
Answer and step-by-step explanation:
Here, we are given a linear equation, meaning that the graph is going to be a straight line. Firstly, we must identify the slope and the y-intercept of the line.
y = -1/2x + 3
The -1/2x is our slope, and the 3 is our y-intercept. So, let's plot the coordinate (0, 3) because that is the y-intercept. Lastly, we must find how steep the line is, and what direction it goes to. As you can see, it is negative, so that means that the slope will go from the top left to the bottom right. And, the slope is -1/2, which means that for every time you go to right two, you will also go down one. Hope this helps!

The third one is 5.875
The fourth one is 7.55
If this helped, I would appreciate it if you marked me brainliest! (°◡°♡).:｡
Answer:
2.03 x 2.5 = 5.075
1.4 x 2.25 = 3.15
2.35 x 2.5 = 5.875
3.02 x 2.5 = 7.55

Answer:
1130.4
Step-by-step explanation:
The volume of a cylinder is πr^2h, where r is the radius and h is the height.
We are given the height, 10m.
The diameter is 2m more than the height, so 2+10=12m.
The radius is half the diameter, so 12m/2=6m.
Use r=6 and h=10 in the formula to get the volume
π6^2*10≈1130.4

Which expression is not equal to the expression shown?
Answer:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex]
Step-by-step explanation:
When pulged into a calculator:
[tex]3^{3}[/tex] ÷ [tex]3^{-4}[/tex] = 2187
When your options are pulged in you get this:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] = [tex]\frac{1}{2187}[/tex]
[tex]3^{3}[/tex] · [tex]3^{4}[/tex] = 2187
[tex]3^{7}[/tex] ÷ [tex]3^0[/tex] = 2187
3 · [tex]3^6[/tex] = 2187
because [tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] doesn't equal 2187 that is your answer.

Write an equation of the line with the given slope and y-intercept: m = -5, b = 4
Answer:
y=-5x+4
Step-by-step explanation:
The equation of the line is y=mx+b. We know what m is and what b is. Therefore, we can plug them into the equation. The line will be y=-5x+4. This is the equation of the line.

A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?
Answer:
3 doors needed
Step-by-step explanation:
The computation of the no of trucks doors that are needed is shown below:
= serve daily ÷ no of store orders ÷ no of store orders
= 50 ÷ 4 ÷ 4
= 3 doors needed
First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come
Andy wants to find the distance across a river.

Find the length of side x in simplest radical form with a rational denominator.
60°
V3
30°
X
Answer:
4√3/3
Step-by-step explanation:
Find the diagram attached below
Considering angle 60°
Opposite side = 2
Hypotenuse = x
Using the SOH CAH TOA identity
sin theta = opposite/hypotenuse
sin 60 = 2/x
x = 2/sin60
x = 2/(√3/2)
x = 2 * 2/√3
x = 4/√3
Rationalize
x = 4/√3 * √3/√3
x = 4√3/3
Hence the value of x in its simplest form is x = 4√3/3
