In function notation (f(x)=mx+b) m represents the slope and b represents the y-intercept.

In a straight horizontal line the slope is always 0. This cancels out the 'x' factor so you get f(x)=b.

To find b you simply look at where the line crosses the y-axis. in this case it crosses at 2.

When you plug in the y-intercept you get f(x)=2

Doss [256]

Answer:

$5565$

Step-by-step explanation:

$1+2+3+4...+113+114=\frac{114*115}{2} =6555$

$1+2+3+4 ... +43+44=\frac{44*45}{2} =990$

Thus, $45+46+47+48...+113+114=$ $6555-990=5565$

Working alone, Ryan can dig a 10 ft by 10 ft hole in 5 hours Castel can dig the same hole in 6 hours how long would it take them

Fed [463]

Answer:

The time taken by both boys to complete work = 2.73 hours

Step-by-step explanation:

Time taken by rayan to dig hole $T_{1}$ = 5 hours

Time taken by castel to dig hole $T_{2}$ = 6 hours

Now the time taken by both persons working together

$T = \frac{T_{1} T_{2} }{T_{1} + T_{2}}$

Put all the values in above formula we get

$T = \frac{ 30 }{6 + 5}$

$T = \frac{30}{11}$

T = 2.73 hours

Therefore the time taken by both boys to complete work = 2.73 hours
