Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
Answer:
Based off of the calculations I did, I got 32 as the answer.
Step-by-step explanation:
Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.
So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.
10/6 * 19 = 31.666...
Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.
31.666... + 4/12 = 32.
Thus, Jason used 32 cans of paint in total.
After a little manipulation, the given diff'l equation will look like this:
e^y * dy = (2x + 1) * dx.
x^2
Integrating both sides, we get e^y = 2------- + x + c, or e^y = x^2 + x + c
2
Now let x=0 and y = 1, o find c:
e^1 = 0^2 + 0 + c. So, c = e, and the solution is e^y = x^2 + x + e.
