You discovered you can deduct medical expenses over 6% of your income. Your income is $42,000, and you had medical expenses of $567. What portion of your medical expenses can you deduct?a) $0
b) $34
c) $567
d) $2,520

Answers

Answer
c) $567

Explanation
The income is $42,000
6% 0f $42,000 = 6/100 ×42,000
                        = 0.06×42,000
                        = $2,520

This is more than your medical expense. This means that the portion that your medical expense that you can deduct is the whole amount, $567.
Your total income is 42,000 dollars and you can deduct 6% of medical expenses from your income.
Now you have 567 dollars medical expenses. Let's solve for the portion of medical expenses we can deduct
=> 6% of your income is Letter 2 520 dollars, since your medical expenses is only 567 dollars, thus you can deduct this all. 

2^x+5 = 3^1-x use logarithms to solve the exponential equation. round answer to 3 decimal places.

Answers

2^(x+5)=3^(1-x)\ \ \ \ \ /log_2()\n\nlog_22^(x+5)=log_23^(1-x)\n\nx+5=(1-x)log_23\n\nx+5=log_23-xlog_23\n\nx+xlog_23=log_23-5\n\nx(1+log_23)=log_23-5\ \ \ \ /:(1+log_23)

x=(log_23-5)/(1+log_23)\n-------------\nlog_23\approx1.5849625\n----------------\nx\approx(1.5849625-5)/(1+1.5849625)\approx-1.321
2^x+5 = 3^1-x
take log on both sides

For the system of equations shown below2x = −y + 6
−4x + 3y = 8
What is the solution to the system of equations?

Answers

2x=-y+6
-4x+3y=8
Rewriting the equations;
y+2x=6
3y-4x=8

Multiplying equation I by 3;
3y+6x=18
3y-4x=8
Subtracting equation II from equation I;
10x=10
x=1

Replacing for x in the first equation;
2x=-y+6
2(1)=-y+6
2=-y+6
2-6=-y
-4=-y

A car travels 70 miles in 80 minutes. Which is its average speed per minute?a. 11 miles
b. 8.75 miles
c. 1.14 miles
d. 0.875 miles User: gopd

Answers

Answer:

The average speed per minute of the car is :

d. 0.875(mi)/(min)

Step-by-step explanation:

The average speed tells you the speed of an object over time, it can be expressed as:

A_(s)=(Distance)/(Time)

As the car travels 70 miles in 80 minutes, we can replace values in the equation:

Distance = 70 miles

Time = 80 minutes

A_(s)=(Distance)/(Time)

A_(s)=(70miles)/(80minutes)

A_(s)=0.875(mi)/(min)
70/80 = miles per minute.
70/80 = 0.857 miles per minute

Answer: d. 0.875 miles
