Answer:
Step-by-step explanation:

The numerator of the rational expression the money he earned for 'x' hours
The rate at which William is paid for each hour in excess of 40 hours 24.
x = 50 hours = (40 + 10 ) hours
The amount paid for excess 10 hours = 24 *10 = 240
Total amount earned for the week = 480 + 240 = 720
Answer:
x=1
Step-by-step explanation:
3^x +1
f(x)=3x+1
f(x) =g(x)
3x +1 =3^x +1
Subtract 1 from each side
3x = 3^x
Let x =1
3*1 = 3^1
3=3
Given, the rate of growth of St. Augustine grass is
cm per week.
We have to find the number of weeks that the grass grow to
cm.
Let's take the number of weeks be x.
In 1 week the grass grow =
cm
So in x weeks the grass grow =
cm
So we can write,

To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,



Now to get we will move 4 to the right side by dividing it to both sides. We will get,


So we have got the required answer.
After 3 weeks the grass grow
.

d) 4/9
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
Given:
f(x)= 2x+3 and g(x)= x²-5.
a) (f+ g)(3)
= f(3)+ g(3)
= 2(3)+3 + (3)²-5
=6+3+9-5
=13
b) (f-g)(4)
= f(4)- g(4)
= 2(4)+3 - (4)²+5
=8+3-16+5
= 0
c) (fg)(-2)
= f(-2)*g(-2)
=[ 2(-2)+3][(-2)² -5 ]
=(-1)(-1)
= 1
d) (g/f)(3)
= g(3)/f(3)
= 3²-5/ 2(3)+3
= 4/9
