Answer:

-10=$35r+$5r

+10=$30r

Step-by-step explanation:

This function represents this situation. If someone orders less than ten rings (-10) then they will pay $35 for each ring($35r) plus dollars for each for shipping ($5r)

If someone were to buy more than ten rings (+10) then they will pay $30 for each ring ($30r)

Have a great day!

Answer:

a = 11c - 4

Step-by-step explanation:

7,18,29,40

constant difference = 11

now,

an = a+(n-1)d

or, an = 7+(n-1)11

or, an = 7 + 11n - 11

or, an = 11n - 4

[tex]\begin{cases} -x+3y=9\\\\ y=\cfrac{2}{3}x \end{cases} \\\\[-0.35em] ~\dotfill\\\\ -x+3y=9\implies 3y=9+x\implies \underline{3y-9=x} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{substituting ont the 2nd equation}}{y=\cfrac{2}{3}(\underline{3y-9})\implies 3y=2(3y-9)}\implies 3y=6y-18\implies 18+3y=6y \\\\\\ 18=3y\implies \cfrac{18}{3}=y\implies \boxed{6=y}[/tex]

Answer:

Yes, they are equivalent expressions, by the Associative Property

Step-by-step explanation:

Both of these expressions are equal to:

4a + 5a + 3c

(and then, 9a + 3c)

This is all adding so you can add them all up without any of the parentheses. In the question at first the parentheses are grouping together the 5a and 3c, but in the second expression they are wrapped around the 4a and 5a. But in both expressions the order of the three terms does not change. Only the grouping changes. The terms are grouped differently, but the order DOES NOT change. This is Associative property. If the order changes it is Commutative property.

Answer:

$ 3.75

Step-by-step explanation:

Let the unknown price be x.

Ounces                                 cost

16                ⇒                  $ 2.50

24                ⇒                   x

Now let us use cross multiplication and find the value of x.

16 × x = 24 × 2.50

16x = 60

Divide both sides by 16.

x = 3.75

Therefore, 24 ounces of bulk rice cost $ 3.75

Hope this helps you :-)

Answer:

Step-by-step explanation:

5 + 2x = y

8 + 3x = y

Answer:

Tree A equation: y = 2x + 5. Tree B equation: y = 3x + 8.

Step-by-step explanation:

The rate at which the tree's grow each month is m (y=mx + b) and the starting length of the trees is b (y=mx+b). Once you know those values plug them into the equation.

Answer:

13.71% or rounded we have 14%

Step-by-step explanation:

We need to find the area so we need to use the formula of Area = piR^2

>> Area of bulls-eye = π(2.5)^2 = 19.63in^2

>> Area of whole target = π(6.75)^2 = 143.13in^2

NOTE: The target values above are halved values of 5 and 13.5

Now, all we have to do is divide the area of the bullseye by the area of the target, so some simple stuff.

19.63/143.13 > 0.13714804 > In a percent we have 13.71% or rounded we have 14%

Step-by-step explanation:

According to the diagram:

The area is:

Answer:

25%

Step-by-step explanation:

Let George's salary = $50,000 per year

If his salary dropped by 20%, then his salary would be 80% of his previous salary (as 100% - 20% = 80%).

Convert 80% to a decimal: 80% = 80/100 = 0.8

Therefore, 80% of 50000 = 0.8 x 50000 = $40,000

We wish to increase his salary back to the original amount of $50,000.

The difference between the two salaries is : 50000 - 40000 = 10000

Therefore, we need to calculate the percentage that $10,000 is of $40,000.

⇒ (10000 / 40000) x 100 = 25%

So George's salary needs to increase by 25% to get back to where it was before the salary drop.

Answer: Irrigation water can come from groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water. As a result, it is critical that farmers protect their agricultural water source to minimize the potential for contamination.

Answer:

Total pipes = 692 pipes

Step-by-step explanation:

Now we have to,

→ find the amount of pipes he use.

Forming the expression,

→ 610 plastic pipes + 82 metal pipes

Let's solve the problem,

→ 610 plastic pipes + 82 metal pipes

→ 610 + 82

→ 692 pipes

Hence, the farmer used 692 pipes.

====================================================

Explanation:

The first term is 9 because of the notation [tex]a_1 = 9[/tex]

To get the second term, we use the recursive rule given to us which is

[tex]a_n = 3a_{n-1} + 3[/tex]

I recommend using parenthesis to separate things like this

[tex]a_n = 3(a_{n-1}) + 3[/tex]

If n = 2, then,

[tex]a_n = 3(a_{n-1}) + 3\\\\a_2 = 3(a_{2-1}) + 3\\\\a_2 = 3(a_{1}) + 3\\\\a_2 = 3(9) + 3\\\\a_2 = 27 + 3\\\\a_2 = 30[/tex]

The second term is 30.

You can use the same idea as above to find the third term, or you can use this slightly different approach

[tex]\text{third term} = 3*(\text{second term}) + 3\\\\\text{third term} = 3*(30) + 3\\\\\text{third term} = 90 + 3\\\\\text{third term} = 93[/tex]

To generate any new term, we first triple the previous term and then add on 3.

Answer:

[tex]-\frac{9h}{5} + 0.7[/tex]

Given :-

To Do :-

Solution :-

Given equation to us is ,

→ y = 3x -1

As we know that , the slope intercept form of the line is ,

→ y = mx + c

where m is the slope and c is the y intercept .On comparing both , we have ,

So the graph will cut the y axis at (0,-1) . And will have a slope of 3 .

When y coordinate is 0 ,

So that ,

→ x - 0 / 0 -(-1) = 3

→ x/0+1 = 3

→ x/1 = 3

→ x = 3

Hence one other point is (3,0 ).

Now we may plot the graph using these two points (3,0) and (0,-1) .

For graph see attachment .
