egoroff_w [7]

Answer:

y=2.50x+4.00

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

m=\$2.50\ per\ hour

The y-intercept (value of y when the value of x is equal to zero) is equal to

b=\$4.00 ----> (fee charge)

substitute the values

y=2.50x+4.00

Timmy is building a new website. Right after he starts, he has 2 visitors. He expects his visitors to increase according to a mo
Alex73 [517]

Answer:

He gets 42 visitors 4 weeks after starting to build his website.

He gets 10 new visitors per week.

Step-by-step explanation:

Equation for the number of visitors:

The equation for the number of visitors Timmy's new website receives after t weeks is:

v(t) = 10t + b

In which b is the number of visitors rightly after he starts.

Timmy is building a new website. Right after he starts, he has 2 visitors.

This means that b = 2, so:

v(t) = 10t + 2

How many visitors does he get 4 weeks after starting to build his website?

This is v(4). So

v(4) = 10(4) + 2 = 40 + 2 = 42

He gets 42 visitors 4 weeks after starting to build his website.

How any new visitors does he get per week?

After 0 weeks:

v(0) = 10(0) + 2 = 0 + 2 = 2

After 1 week:

v(1) = 10(1) + 2 = 10 + 2 = 12

2 weeks:

After 2 week:

v(2) = 10(2) + 2 = 20 + 2 = 22

22 - 12 = 12 - 2 = 10

He gets 10 new visitors per week.

Help me pleaseee asap !!!
frosja888 [35]

Step-by-step explanation:

5x+3x-14=180

8x-14=180

8x=180+14

8x=174

x=174/8

x= 21.75°

if x is 21.75°, then 5x is 108.75°

which means 3x-14 is 51.25°

therefore, f +108.75+51.25=180

f = 180-160

f=20°
