Simplifying
3x + -4y = 16
Solving
3x + -4y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
3x + -4y + 4y = 16 + 4y
Combine like terms: -4y + 4y = 0
3x + 0 = 16 + 4y
3x = 16 + 4y
Divide each side by '3'.
x = 5.333333333 + 1.333333333y
Simplifying
x = 5.333333333 + 1.333333333y
The excluded value is -16

Answer:
<u>→To combine the two functions, you have to multiply them together, like so:</u>
h(x) · s(x)
<u>→This can also be shown as:</u>
<u />
The reason as to why you would multiply the two functions together, and not add, is because of the words accrues. Based on the information given, the interest amount of money, which is $103, accrues, which basically means that the money will increase in a pattern, over time. In addition, when a world problem involves a bank and money, multiplication is usually occurring.
Answer:
43 1/3 minutes to iron 10 shirts
Step-by-step explanation:
Number of shirts : Time taken
3 shirts : 13 minutes
10 shirts : x minutes
3 / 13 = 10 / x
Cross product
3 * x = 13 * 10
3x = 130
Divide both sides by 3
3x / 3 = 130 / 3
x = 43 1/3 minutes
x = 43 minutes 20 seconds
It will take 43 minutes 20 seconds to iron 10 shirts
