Grayson charges $35 per hour plus a $35 administration fee for tax preparation. ian charges $45 per hour plus a $15 administration fee. if h represents the number of hours of tax preparation, for what number of hours does grayson charge more than ian?
h less-than 2
h greater-than 2
h less-than 5
h greater-than 5

h less-than 2

Step-by-step explanation:

Let

h ---> the number of hours

y ---> the total charge in dollars

we know that

The linear equation is slope intercept form is equal to

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

we have

Grayson

The slope is equal to

The y-intercept is

so

The total charge is equal to

----> equation A

Ian

The slope is equal to

The y-intercept is

so

The total charge is equal to

----> equation B

For what number of hours does Grayson charge more than Ian?

The inequality that represent this situation is

solve for x

Group terms

Divide by 10 both sides

Rewrite the expression

----> h less than 2 hours

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
