Can you help me with a few more? http://prntscr.com/39mog2 http://prntscr.com/39mokz http://prntscr.com/39mon6
que 2 its option 1 since y<= 8
For the first one, just pretend that the inequality is just an equal sign. How would you solve for y?
The next two are the exact same as I did. Simply add the required constant to each side. The last one you multiply by 5 on each side. But be careful, because if you ever multiply or divide by a negative, you HAVE to switch the inequality. Just not in this case.
Thanks but i don't get what you do in the last question
It's the same thing. If the inequality were an equal sign, what would you do? The same rules apply unless multiplying or dividing by a negative number.
I just came over seas so this stuff is hard for me to understand but i will try
Can you solve for y if y - 8 = 7? If so, it is the same rules. If not we can help you with that as well.
Yeah i dont know this stuff :/ Can you help me by giving me the answers?
...it will be better for you to understand how to find the answer. You must put each inequality in a simple form by isolating the variable (x or y). To do this you can MUST treat each side the same way, otherwise you disrupt the inequality.
Is there a good website to learn this stuff i don't understand this :/
Well to solve for y you have to isolate y. In the example I provided above, you must add 8 to both sides. This will get rid of the 8 that is with the y, since -8 + 8 = 0. You must add 8 to BOTH sides in order for this to work: y - 8 = 7 y - 8 + 8 = 7 + 8 y = 15 I can try to look for a website if you'd like.
https://www.khanacademy.org/ I have heard great things about khan academy, and they have every level of math. I highly suggest you give it a look, and from what I know it is completely free.
I will try to learn it after i finish this test i just need to get back on track with my work so i can go back and study them. Is it ok if you can give me the answers for the questions and i can study this after i finish and get back on track with my work
@sylbot beat me to it whoops
For the first one try adding 6 to both sides. This will isolate the y-value.
ok
