The method to solve this kind of questions is find where the graph meets the x axis then add ten units to it .The obtained x coordinate is the point where the second graph meets the x axis.

Now first find where the F(x)=2x+3 meets the x axis by substituting F(x)=0.

$2x+3=0$

$x=-\frac{3}{2}$

Now add 10 to this x coordinate , we get x1= $10-3/2$ = $17/2$

this is x coordinate where the second line meets the x-axis.

The second line is F(x)=2x-k.

now f(x)=0 and x=17/2

On substitution we get $0=2*17/2-k$

k=17

Answer: Twelve fifth of an Hour

Step-by-step explanation: a whole is represented by 1

1/3=4/5hours

Whole room 1 =4/5 ÷ 1/3

=4/5×3/1

=4×3/5

=12/5

That's twelve fifth of an hour

Answer:

f(7)=13

g(-9)=86

Step-by-step explanation:

f(7)=2*7-1=14-1=13

g(-9)=(-9)^2+5=81+5=86
