Answer:

The bottom left

Step-by-step explanation:

To solve we can create an equation to represent the problem given. In this case, the equation should be linear. This is because the total cost will change by the same amount each time the number of burritos changes. The slope (the amount the cost changes per burrito) is $6.50 because that is how much one burrito costs. So, the function would look like- y=6.5x. Plug in the x-values for the number of burritos and that will give the cost. Once you solve this equation, the bottom left chart is the only one that matches the values.

Answer:

Each side of the Rhombus is equal to 4x

Answer:

Sarah is correct: lines l and m are not parallel.

Step-by-step explanation:

Given that m < 1 = 130°, and m < 7 = 45°,

Sarah is correct, that lines l and m are not parallel.

If lines l and m were parallel cut by the transversal, n, then its exterior angles < 1 and < 7 that lie on the same side of the transversal should be supplementary.  In other words, m < 1 and m < 7 should have a sum of 180°

Since according to the given prompt that m < 1 = 130°, and m < 7 = 45°, the sum of their measure add up to 175°, and not 180°.

Therefore, lines l and m are not parallel.

      The question gives us two points,  (-3,-3) and (-9,5), from which we can find the slope and later the equation of the line.

Finding the Slope  

The slope of the line (m)   = (y₂ - y₁) ÷ (x₂ - x₁)

                                           = (5 -(-3)) ÷ (-9 -(-3))      

                                           =  (5 + 3) ÷ (-9 + 3)    

                                           =   - ⁴/₃  

Checking my answer visually:  

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. Once we have that equation, we can graph it to see if it passes through the two points. If it does, then we calculated the slope correctly.

                                ⇒  y - (-3) = - ⁴/₃ (x - (-3)        [ using the point (-3, -3)]

                                       y + 3  = - ⁴/₃ (x + 3)

Using the concept of inequality, the number of minutes which ensures that the park makes profit while also ensuring that the park isn't overcrowded ls expressed below :

Given the Parameters :

The number of minute to keep the gates opened :

c + rm ≤ 4500

850 + 12m ≤ 4500

12m ≤ 4500 - 850

12m ≤ 3650

m ≤ (3650÷ 12)

m ≤ 304.16

Hence, the gates should be left opened for at most 304 minutes

B.)

In other to allow atleast 2800 in for profit sake

850 + 12m ≥ 2800

12m ≥ 2800 - 850

12m ≥ 1950

m ≥ 162.5

The gates should be opened for 163 minutes.

C.)

In other to make profit by allowing atleast 2800 people in while also ensuring that not more than 4500 people are in the park ; the inequality representing the number of minutes the gates should be open is :

Step-by-step explanation:

Percentage decrease = 30% × 25

New value = 25 - Percentage decreaseNew value =

25 - Percentage decrease =

25 - (30% × 25) =

25 - 30% × 25 =

(1 - 30%) × 25 =

(100% - 30%) × 25 =

70% × 25 =

70 ÷ 100 × 25 =

70 × 25 ÷ 100 =

17.5

Absolute change (actual difference) =

New value - 25 =

17.5 - 25 =

- 7.5

Answer:

25 decreased by 30% equals 17.5

Step-by-step explanation:

To solve this, we need to make our equation to solve.

x/25=30/100

We did x because we don't know what 30% of x is. The 25 shows the total, while the right side shows the percent.

Now cross multiply

100x=750

Now divide both sides by 100.

you will get x=7.5

So now we know that 7.5 is 30% of 25. Now, subtract 7.5 from 25 in order to find out what 25 decreased by 30% is.

25-7.5=17.5

So the answer is 17.5

Answer:

Answer:

x = 1/4

Step-by-step explanation:

Given 2/x = 8:

Multiply both sides by x to eliminate the fraction:

[tex](x)(\frac{2}{x}) = 8(x)[/tex]

2 = 8x

Divide both sies by 8 to solve for x:

[tex]\frac{2}{8} = \frac{8x}{8}[/tex]

1/4 = x

To verify whether it is the correct answer, substitute x = 14 into the original equation:

[tex]\frac{2}{x} = 8[/tex]

[tex]\frac{2}{\frac{1}{4} } = 8[/tex]

2 * 4/1 = 8

8 = 8 (True statement).

Therefore, the correct answer is x = 1/4

Answer:

(Down Below)

Step-by-step explanation:

Plug in the value of x in the left column for all the values in the equation. I will do a couple for you.

Since -4 is the value of x, substitute it into the equation for x.

[tex]y= -4-5=-9[/tex]

-1

[tex]y=-1-5=-6[/tex]

0

[tex]y=0-5=-5[/tex]

You can do the rest. You got this! Comment if you need more help!

Answer:

y = -4 - 5 = -9

y = -1 - 5 = -6

y = 0 - 5 = -5

y = 2 - 5 = -3

y = 5 - 5 = 0

y = 8 - 5 = 3

Answer:

Answer B is closest:  5.8 units

Step-by-step explanation:

Points M and N appear to lie in the same plane, so this problem is a 2-dimensional one.  The distance along the x axis from N to the origin is 5 units and that along the y axis from the origin to M is 3 units.  We apply the Pythagorean Theorem, as follows:

d = √(3² + 5²), or

d = √34, which is approximately 5.83 units.  Answer B is closest:  5.8 units.

Answer:

(-infinity, 2) U [-3]

Step-by-step explanation:

Step 1: we want to solve both equations for x. To do so, get the x variable by itself in both equations.

1.)  3x+4 = 5x+10

    -6 = 2x  (subtract 10 from both sides and 3x from both sides)

    -3 = x     (divide 2 from both sides)

2.) -5x + 7 > -3

     -5x > -10  (subtract 7 from both sides)

       x < 2      

(divide both sides by -5, notice that dividing by a negative by a negative number flips the direction on > to < .)

Step 2: apply interval notation to these answers. Since x DOES equal -3 in equation one, it'll be in a bracket. On the contrary, since x has to be LESS THAN 2, it will have a parentheses.

So, our answer is: (-infinity, 2) U [-3]

*note the parentheses around infinity because something cannot equal infinity, it's not just one number*
