Answer:

t(g)= -4g + 20

Step-by-step explanation:

James is playing his favorite game at the arcade. After playing the game 3 times, he has 8 tokens remaining. He initially had 20 tokens, and the game costs the same number of tokens each time. The number tt of tokens James has is a function of gg, the number of games he plays

Solution

Let

g=No. of games James plays

t= No. of tokens James has.

Find the slope using

y=mx + b

Where,

m = Slope of line,

b = y-intercept.

Before James started playing the games, he has a total of 20 tokens.

That is, when g=0, t=20

After James played the games 3 times, he has 8 tokens left

That is, when g=3, t=8

(x,y)

(0,20) (3,8)

m=y2-y1 / x2-x1

=(8-20) / (3-0)

= -12 / 3

m= -4

Slope of the line, m= -4

y=mx + b

No. of tokens left depend on No. of games James plays

t is a function of g.

t(g)

t(g)= -4g + 20

Need help thanks :) The question is down below

astra-53 [7]

Answer:

n=63

x=117

r=63

p=117

w=117

m=117

k=117

Step-by-step explanation:

If you start with the given angle of 63 p would have to be 117 because 180-63 is 117. This would make r 63 because you would use the 117+63 to make a 180 degree angle. w will then be made 117 because it's vertical to p and vertical angles are congruent. we can find x by using corresponding angles. x= k because they are corresponding angles as well. n would be 63 because of k being 117 and because of vertical angles m is 117.

Hope this helps :)

For which intervals below is the average rate of change less than or equal to zero?

77julia77 [94]

Answer:

Intervals A and C only

Step-by-step explanation:

we know that

The graph show a vertical parabola open upward

The vertex represent a minimum

The vertex is the point (-6,-9)

Remember that the vertex is a turning point

That means

In the interval (-∞,-6) the function is decreasing (rate of change is negative)

In the interval (-6,∞) the function is increasing (rate of change is positive)

therefore

<u><em>Verify each case</em></u>

Interval A) A -13 ≤ x ≤ -10

Belong to the decreasing interval, so the rate of change is negative

Interval B) -5 ≤ x ≤ 0

Find the rate of change

the average rate of change is equal to

$\frac{f(b)-f(a)}{b-a}$

In this problem we have

$a=-5$

$b=0$

$f(a)=f(-5)=9$

$f(b)=f(0)=0$

Substitute

$\frac{9-0}{0+5}=9/5$

so

Interval B the rate of change is positive

Interval C) --10 ≤ x ≤ -2

Find the rate of change

the average rate of change is equal to

$\frac{f(b)-f(a)}{b-a}$

In this problem we have

$a=-10$

$b=-2$

$f(a)=f(-10)=-5$

$f(b)=f(-2)=-5$

Substitute

$\frac{-5+5}{-2+10}=0$

so

Interval C the rate of change is zero

therefore

Intervals A and C only
