Answer:

4 Tacos

Step-by-step explanation:

It cost less for four tacos then five tacos

Answer: 4 tacos for 3.20

Step-by-step explanation: if you divide 3.20 by 4 it equals 0.80 cents for each taco and 4.25 divided by 5 equals 0.85 cents for each taco.

Answer:

y=mx+c y= -2/7+5/2 if this is right can i get brainliest and if u need explanation just ask

Answer:

D. y = -7/2x+5/2

Step-by-step explanation:

The formula for the graph would be: y = mx + c where m is the slope and c is the y-intercept.

Based on the graph, you can see that the y-intercept is 5/2 (somewhere between 5 and 0) so A and C are out. Remaining are options B and C.

Now, the slope is either -2/7 or -7/2. We will have to calculate the slope then. I will be using the points (-1, 6) and (1, -1)

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-1-6}{1-(-1)}[/tex]

    = [tex]\frac{-7}{2}[/tex]

   = -[tex]\frac{7}{2}[/tex] (Same as option D)

Thus, the equation would have been: -[tex]\frac{7}{2}[/tex]x + [tex]\frac{5}{2}[/tex]

Answer:

Sherry have 8 crayons.

Step-by-step explanation:

Marie has 32 crayons.

Sherry has 1/4 as many crayons as Marie.

We need to find how many crayons does Sherry have. It means we need to find 1/4 of 32. Let the answer is x.

[tex]x=\dfrac{1}{4}\times 32\\\\=8\ \text{crayons}[/tex]

Hence, Sherry have 8 crayons.

Step 2: Find slope m

Answer:

y=8x+5

Step-by-step explanation:

Given:

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

To find:

The equation of the perpendicular bisector of NY.

Solution:

Midpoint point of NY is

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-11+3}{2},\dfrac{5-3}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-8}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-4,1\right)[/tex]

Slope of lines NY is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-3-5}{3-(-11)}[/tex]

[tex]m=\dfrac{-8}{14}[/tex]

[tex]m=\dfrac{-4}{7}[/tex]

Product of slopes of two perpendicular lines is -1. So,

[tex]m_1\times \dfrac{-4}{7}=-1[/tex]

[tex]m_1=\dfrac{7}{4}[/tex]

The perpendicular bisector of NY passes through (-4,1) with slope [tex]\dfrac{7}{4}[/tex]. So, the equation of perpendicular bisector of NY is

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-1=\dfrac{7}{4}(x-(-4))[/tex]

[tex]y-1=\dfrac{7}{4}(x+4)[/tex]

[tex]y-1=\dfrac{7}{4}x+7[/tex]

Add 1 on both sides.

[tex]y=\dfrac{7}{4}x+8[/tex]

Therefore, the equation of perpendicular bisector of NY is [tex]y=\dfrac{7}{4}x+8[/tex].

Answer:

Step-by-step explanation:

Answer: C. 2

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Begin by removing the brackets

4x + 5(-4x - b) = -16x - 5b

-(x - 2) = -x + 2

Add the two binomials together to get the third one

4x -20x - 5b - x + 2 = -17x - 8                 Combine the like terms on both sides

-17x - 5b +2 = -17x - 8                             Add 17x to both sides

-5b + 2 = - 8                                           Subtract 2 from both sides

-5b +2 -2 =- 8 -2                                     Combine    

-5b =  - 10                                               Divide by -5

b = -10/-5

b = 2

Answer:

С.

Step-by-step explanation:

From the options provided the only one that represents a proportional relationship was The cost of purchasing a box of socks for $1.75 per sock plus $2.15 for the box. This is because the total cost of the boxes depends on the number of socks that are bought since every pair of socks that are bought comes with a box which causes the total costs of the boxes to increase. Therefore, the number of sock pairs and the number of boxes has a proportional relationship.

Answer:

The gas pump filling the gallons in 1 minute will be: 15

Step-by-step explanation:

As there are 60 seconds in 1 minute.

Thus,

Gas pump filling the gallons in 1 minute will be:

[tex]60\:\times 2^{-2}[/tex]

[tex]=60\times \frac{1}{2^2}[/tex]             ∵ [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}[/tex]

[tex]=\frac{1\times \:60}{2^2}[/tex]

[tex]=\frac{60}{2^2}[/tex]

[tex]=\frac{2^2\times \:3\times \:5}{2^2}[/tex]

[tex]=3\times \:5[/tex]

[tex]=15[/tex] gallons in one minute

Therefore, the gas pump filling the gallons in 1 minute will be: 15

Answer:

28

Step-by-step explanation: This should be 28. 42 divided by 3 is 14. Why would you divide it by 3? Because the full ratio is 2:3. So 42 divided by 3 is 14. Then you add fourteen twice, for the two in the ratio. Fourteen plus fourteen is 28.
