Answer:
all u have to do is find the second difference
Answer:
$29.50
Step-by-step explanation:
Not sure how your teacher wants you to round up.
$29.4975
Rounded -> $29.50
I'm assuming 2 decimal places; would be $29.50.
We are given the following equation and want to find the possible values of x

Subtract both sides by 3x


Now, we have this weird equation. Since -15 is NOT equal 15 and there is no other way we could have solved for x, there is no real solution to the given equation.
In other words, there is no value of x that makes the equation true.
Let me know if you need any clarifications, thanks!

For Q3, you can subsitute x = 2 and y = 5 into the systems
-5(2) + 5 = -5
so it's a solution for the first system
-4(2)+2(5) = 2
it's also a solution for the second system
R. The First letter comes before S, T, U, V, and W
