Answer:
Step-by-step explanation:
5.64 is greater than 5.624
Look at the hundredths place, (third place from left to right)
4 is bigger than 2
There is no value that x cannot be for linear equations.
Thus, the domain is ALL REAL NUMBERS.
CHOICE B.
4.5 divided by 1.25 is 3.6
for peices in total it is 4.
for peices the right length it is 3
I won't answer them all for you (don't want to cheat - need to learn something).
But for the first one given:
<span>-2x-9y=-25
-4x-9y=-23
you set up either x or y (which ever one you want to eliminate) so that one of them cancels.
So this one is easy - you just have to multiply an entire row by negative (doesn't matter which one) - so that the y's will be + and -
Since they're both 9 and they're subracting NOW - you can eliminate the y value. Now add/subtract the x's. So it'd be -2 or 2 depending on how you eliminated y. Then add the number outside of the = sign. Now just solve for x. After that plug in whatever you got for x into both of the rows. Then find the y value.
Hopefully this wasn't confusing -- reply if it is and I will try to simplify. I can give you contact if you need help with the rest
Good luck!</span>
