If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.
5x+3 is always 3 greater than 5x also.
Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)
So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4
You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.
So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004
Those are in ascending order, so that must be the right order!
After the new test, she now has taken 8 tests.
Set it up just like when finding the average:
(87+79)/8
Solve for the new test average
The first one is 9k cause you’re multiplying it and the second one is -18 because you’re multiplying -2 and 9
Answer:
false
Step-by-step explanation:
<u>Step :1</u>
Given x- 2 y =5 .......(1)
put x=1 and y= -3 on left hand side of given equation
1 - 2 (-3) = 5
1 + 6 = 5
7 ≠ 5
both sides are not equal
so it is false
