Answer:

The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65

Step-by-step explanation:

Let x be the number of t-shirts and y be the total pay

As we can clearly see in the table that there is a linear relationship between x and y

A linear function is given as:

[tex]y = mx+b[/tex]

Here m is the gradient of the function then

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

Taking any two pairs of x and y

(1,68) and (2,71)

[tex]m = \frac{71-68}{2-1}\\m = 3[/tex]

Putting in equation

[tex]y = 3x+b[/tex]

Putting a pair (1,68) in the equation to find the value of b

[tex]68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65[/tex]

Putting the value of b

[tex]y = 3x+65[/tex]

Let p(x) be the linear function

Hence,

The linear function is: p(x) = 3x+65

Answer:

y=3x+65

Answer:

14x>200+5.5, She must sell 15 or more vases

Step-by-step explanation:

14x>200+5.5

14x>200+5.5

14x>205.5

x>14.68*

She must sell 15 or more vases

*You round up because you cannot sell a partial vase

Answer:

14v > 200 + 5.50v, she will have to sell 24 vases to make a profit

Step-by-step explanation:

It costs $5.50 PER VASE for materials, so you would subtract this from what she sells each vase for. 14 - 5.50 = 8.50. She makes an $8.50 profit per vase sold. We can write 8.50n > 200 to show her profit margin minus the booth fee. If she sold 24 vases, she would be making a profit and this would represent the lowest amount of vases she can sell to make a profit. We can write the inequality 24 ≤ n to show that she can sell 24 vases or more to make a profit.

14n > 200 + 5.50n

336 > 332, true

n > 23

(x-7)(x-3)

find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10

Answer:

(x - 7)(x - 3)

Step-by-step explanation:

Given

x² - 10x + 21

Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (- 10)

The factors are - 7 and - 3 , since

- 7 × - 3 = + 21 and - 7 - 3 = - 10, thus

x² - 10x + 21 = (x - 7)(x - 3) ← in factored form

Answer:

Step-by-step explanation:

Let functions be

As per given ratios:

The smallest slope belongs to f(l), greater - f(d), the greatest - f(j)

Possible graphs reflecting the functions are graph 1 and graph 3

The next two term is 13 and 16 respectively.

Step-by-step explanation:

here,

a1 = -2

a2 = 1

a3 = 4

a4 = 7

a5 = 10

So, d = a2 - a1 = 1 - (-2) = 3

= a3 - a2 = 4 - 1 = 3

Here, Common difference is same everywhere and the value of d is 3

Then,

To find 6th term of this sequence

a6 = a5 + d

= 10 + 3

a6 = 13

To find 7th term of this sequence

a7 = a6 + d

= 13 + 3

a7 = 16

Thus, The next two term is 13 and 16 respectively.

Answer:

There are 28 horses and 140 cows

Step-by-step explanation:

Given

Animals: Cows and Horses

Represent Cows with c and Horses with h

For the first equation, we complete it as thus:

[tex]c = 5h[/tex]

This is so because there are 5 times as many c as h

The second equation will be completed as:

[tex]c + h = 168[/tex]

This is so because the total animals are 168

So, we have:

[tex]c = 5h[/tex]

[tex]c + h = 168[/tex]

Substitute 5h for c in the second equation

[tex]c + h = 168[/tex]

[tex]5h + h = 168[/tex]

[tex]6h= 168[/tex]

Solve for h

[tex]h = 168/6[/tex]

[tex]h = 28[/tex]

Recall that:

[tex]c = 5h[/tex]

[tex]c = 5 * 28[/tex]

[tex]c = 140[/tex]

Hence, there are 28 horses and 140 cows

Answer:

The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Answer:

There were 250 hamburgers sold on Saturday.

Step-by-step explanation:

∵ A local hamburger shop sold a combined total of 555 hamburgers

   and cheeseburgers on Saturday

→ Assume that the shop sold x hamburgers

∵ The shop sold x hamburgers

∵ There were 55 more cheeseburgers sold than hamburgers

→ That means the number of cheeseburgers is greater than the

    number of hamburger by 55

∴ The shop sold x + 55 cheeseburgers

∵ The shop sold 555 burgers

→ Add the two types of burgers and equate the sum by 555

∴ x + x + 55 = 555

∴ 2x + 55 = 555

→ Subtract 55 from both sides

∴ 2x + 55 - 55 = 555 - 55

∴ 2x = 500

→ Divide both sides by 2 to find x

∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{500}{2}[/tex]

∴ x = 250

∵ x represents the number of hamburgers

∴ There were 250 hamburgers sold on Saturday.

It 's an isosceles triangle if you look carefully. 2 Sides of the triangle are equal which is denoted by those marks. The angles opposite to the equal sides are always equal, so: [tex]m\angle FST = 64^\circ[/tex]

By angle sum property, [tex]m\angle TFS = 180 - 2 * 64 = 180 - 128 = 52^\circ[/tex]

52 degrees is the answer: Option D :D

Sum of the interior angles of any triangle is 180° .

[tex]64° + F + 64° = 180°[/tex]

[tex]F + 128° = 180°[/tex]

Subtract sides 128°

[tex]F + 128° - 128° = 180° - 128° \\ [/tex]

[tex]F = 52°[/tex]

So :

[tex]TFS = F = 52°[/tex]

Answer:

The rate of change is y with respect to x is [tex]\frac{25}{4}[/tex]

Step-by-step explanation:

Given

[tex]25x - 4y = 50[/tex]

Required

Determine the rate of change of y w.r.t x

[tex]25x - 4y = 50[/tex]

First, make y subject of formula

[tex]4y = 25x- 50[/tex]

Divide through by 4

[tex]y = \frac{25x}{4} - \frac{50}{4}[/tex]

[tex]y = \frac{25x}{4} - 12.5[/tex]

Next, we differentiate the above w.r.t to x

The result of the differentiation is the solution to the question

[tex]y' = 1 * \frac{25x^{1-1}}{4} -0[/tex]

[tex]y' = 1 * \frac{25x^0}{4}[/tex]

[tex]y' = 1 * \frac{25*1}{4}[/tex]

[tex]y' = \frac{25}{4}[/tex]

Hence, the rate of change is y with respect to x is [tex]\frac{25}{4}[/tex]

By calculating derivative of y with respect to x we got rate of change of y with respect to x for 25x-4y=0 is 25/4

Rate of change of a function with respect to a variable is called derivative of that function with respect to that variable .

Here given relation is 25x-4y=0

[tex]\Rightarrow 4y=25x\\\\\Rightarrow y=\frac{25x}{4}[/tex]

We have to calculate rate of change of y with respect to x so we will calculate derivative of y with respect to x.

we can calculate derivative of y with respect to x as

[tex]\frac{dy}{dx}= \frac{d}{dx} (\frac{25x}{4})\\\\[/tex]

As 25/4 is constant we can take it out from derivative function as it is

[tex]\frac{dy}{dx}= (\frac{25}{4})\frac{dx}{dx}\\\\[/tex]

And we know derivative of a variable with respect to itself is 1

so

[tex]\frac{dy}{dx}= (\frac{25}{4})\times 1\\\\ \frac{dy}{dx}= \frac{25}{4}[/tex]

By calculating derivative of y with respect to x we got rate of change of y with respect to x for 25x-4y=0 is 25/4
