Answer:
(3,6)
Step-by-step explanation:
2x-3y = -12
x+y=9. Solve for either y or x
-x. -x
y = -x + 9. Substitute this for the y
2x-3(-x+9)= -12
2x +3x-27 = -12. Add like terms
5x -27 = -12
+27. +27. Inverse operations
5x = 15
÷5. ÷5
x = 3
x + y = 9
3 + y = 9. Substitute 3 for x
-3. -3. Inverse operations
y = 6
Answer:
let g be f(x)
g= <u>4</u><u>x</u><u> </u><u>-</u><u>3</u>
. 7
make x the subject
<u>7</u><u>g</u><u> </u><u>+</u><u>3</u><u>. </u> =x
4
the inverse function of f(x) = <u>7</u><u>x</u><u>+</u><u>3</u>

Hey there!
Here are the steps involved in answering this question:
1. Write 12 out of 32 as a fraction which is
2. Turn the fraction into a decimal. To do this, divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

= 0.375
3.<span> You get 0.375. Now, turn this into a percent. Move the decimal, 2 places to the right or just multiply the decimal by 100.</span>
0.375 = 37.5%
The final answer is 37.5%.

Okay, so if it leaks out a pint every hour, and a gallon is 8 pints, it will take 8 hours to leak out 1 gallon. Since there are 24 hours in a day, it would leak out 3 gallons every day. Now, assuming the month we are talking about is 31 days, then we multiply 31 with 3, giving us 93 gallons in a month.
Do you need help with the third too?
500 thousandths is equal to five tenths. Thus, we have a five in the tenths place and an eight in the hundredths place, so we have .58 as our answer.
