Answer:

m=2

Step-by-step explanation:

(−2,−3);(3,7)

(x1,y1)=(−2,−3)

(x2,y2)=(3,7)

Use the slope formula:

m=y2−y1/x2−x1

=7 − −3/3 − −2

=10/5

Graph:

(-2,-3) is blue

(3,7) is red

Answer:

m=2

Step-by-step explanation:

m=y2-y1/x2-x1

m= 7-(-3)/3-(-2)

m=7+3/3-(-2)

m=10/3-(-2)

m=10/3+2

m=10/5

m=2

A tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24. The players were still hungry so the coa

g100num [7]

The cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8

<h3><u>Solution:</u></h3>

Let "f" be the cost of 1 fries

Let "h" be the cost of 1 hamburger

<em><u>Given that, tennis coach took his team out for lunch and bought 8 hamburgers and 5 fries for $24</u></em>

8 x cost of 1 hamburger + 5 x cost of 1 fries = 24

$8 \times h + 5 \times f = 24$

8h + 5f = 24 -------- eqn 1

<em><u>The players were still hungry so the coach bought six more hamburgers and two more fries for $16.60</u></em>

6 x cost of 1 hamburger + 2 x cost of 1 fries = 16.60

$6 \times h + 2 \times f = 16.60$

6h + 2f = 16.60 ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

Multiply eqn 1 by 2

16h + 10f = 48 ------ eqn 3

Multiply eqn 2 by 5

30h + 10f = 83 -------- eqn 4

<em><u>Subtract eqn 3 from eqn 4</u></em>

30h + 10f = 83

16h + 10f = 48

( - ) ----------------------

14h = 35

Substitute h = 2.5 in eqn 1

8(2.5) + 5f = 24

20 + 5f = 24

5f = 4

Thus cost of 1 hamburger is $ 2.5 and cost of 1 fries is $ 0.8

Write the equation for the inverse of the function y=Cos^-1(x-pi)

ser-zykov [4K]

we are given

$y=cos^{-1}(x-\pi)$

Since, we have to find inverse function

step-1:

Set y=f(x)

It is already there

step-2:

Switch x and y

$x=cos^{-1}(y-\pi)$

step-3: Solve for y

We can take cos on both sides

$cos(x)=cos(cos^{-1}(y-\pi))$

we can simplify it

$cos(x)=y-\pi$

now, we can solve for y

$cos(x)+\pi=y-\pi+\pi$

$cos(x)+\pi=y$

$y=\pi +cos(x)$ ..............Answer
