The first picture is the graph (already answered) and the second is the next

Nastasia [14]

Answer:

a) 100/15 = 6.6667 = 6 2/3

b) C = T( 6 2/3)

= T (6 + 2/3)

C = 1T x 6 2/3

= 6 2/3 T

We can show T as time at end of equation or start of brackets

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of _2?

Crank

The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28

Find the distance between the points (3, 8) and (0,4).

Bingel [31]

Answer:

5

Step-by-step explanation:

(3,8) (0,4)

X1 = 3 X2 = 0

Y1 = 8 Y2 = 4

$D=\sqrt{(X1-X2)^{2}+ (Y1-Y2)^{2} }$

$D= \sqrt{(3-0)^{2} + (8-4)^{2} }$

Do what's in the parentheses so...

3-0= 3
8-4= 4

Now plug it in!

$D= \sqrt{(3)^{2}+(4)^{2} }$

Now you are going to finish the parentheses so...

(3)^2= 9
(4)^2= 16

Plug that in so that you have this...

$\sqrt{9+16}$

Add 9+16 to get...

$\sqrt{25}$

Then you are going to find the number or numbers that make this a perfect square...

$\sqrt{25}= 5$

So 5 is your answer
