Solve the equation a minus 2 and one-half = 1 and one-half

1 answer:

7 0

A would equal 4 because you would first convert the mixed numbers into improper fractions, then move the constant to the right, and finally add the factions

a-2(1/2)=1(1/2)
a-(5/2)=(3/2)
a=(3/2)+(5/2)
a=4

The function C(x) = 25.50x + 50 models the total cost for a cleaning company to clean a house, where x is the number of hours it

Answer:

The average rate of change is $25.5 per hour, option B.

Step-by-step explanation:

Average Rate of Change

When we are explicitly given some function C(x), we sometimes need to know the rate of change of C when x goes from $x=x_1$ to $x=x_2$ . It can be computed as the slope of a line .

$\displaystyle m=\frac{C(x_2)-C(x_1)}{x_2-x_1}$

The provided function is

$C(x)=25.50x + 50$

We are required to compute the average rate of change between the points

$x_1=3\ ,\ x_2=9$

Let's compute

$C(3)=25.50(3) + 50=126.5$

$C(9)=25.50(9) + 50=279.5$

$\displaystyle m=\frac{279.5-126.5}{9-3}$

$\displaystyle m=\frac{153}{6}=25.5$

The average rate of change is $25.5 per hour, option B.

2. Ramone and his wife had $72,380.90 in combined gross income in 2010. They had $8,295.00 in various adjustments and deductions

MAVERICK [17]

Let x = taxable income = difference of gross income and deductions T = income tax paid = amount sent to the government Use the "filing jointly" chart on the right side. You'll use the second row of that chart since subtracting $72,380.90-$8,295.00 leads to a value between 16750 and 68000. That second row turns into this equation T=1675+0.15(x-16750) where 16750<x≤68000
