Ez
This is non-proportional
There are 3 ways to figure out if a table is proportional or not
The one i used in which if u make fractions like 2/24. They should be equal to another fraction taken from your table
2/24 simplified is 1/12 while 8/36 is 2/9.
So

NON-PROPOTIONAL

Help please!! i don’t understand this one!

Answer:

C, D

Step-by-step explanation:

This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

$x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

In the given equation, a=2, b=11, c=5, so this becomes ...

$x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}$

The solutions are ...

C. x = -5

D. x = -1/2

_____

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.

Must choose a number between 55 and 101 that is a multiple of , 69, and 18 .

solong [7]

I'm certain there isn't a number that satisfies your conditions.
There's one multiple of 69 between 55 and 101: 69
And two multiples of 18 between 55 and 101: 72 and 90.

Is 0.121122111222 a repeating or terminating decimal? If so, why?

oksian1 [2.3K]

Answer:

I'm just guessing that it is. That question is on my math homework and the definition in the back of my math book says: A decimal in which one or more digits repeat infinitely and I put yes. Because they repeat.
