You first have to set up the two equations. Y is equal to the total number of gallons in a tank and x is equal to the number of hours the tanks are filling.
Since the two equations both equal y I can make them equal each other. I then solved for x as you see and got -4.
Once I found my x value I now needed to find my y. You only needed to chose one equation to solve for y, so I decided to do the first one. I plugged in -4 where my x value currently was and solved for y. I got 2.
If you have any questions please comment!! Hope this helps!!
Answer:
no
Step-by-step explanation:
If x = 3 is a zero, then f(3) = 0
f(3)
= 4
- 3³ - 52(3)² - 35(3) + 12
= 324 - 27 - 468 - 105 + 12
= - 264
Since f(3) ≠ 0 then x = 3 is not a zero of f(x)
When x = 1 (that is x > 0) f(1) = 1^2 - 1 = 0
So b is correct

Answer:
In mathematics, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix.
