Yeah, none of these are handy… Jesus these teachers have gotten smarter…
Kinda cool seeing that people still actively talk here- How’re y’all doing?
Wait no I’m dumb, it was 125. 1. is 18:1 2. Is 125 3. Is 27 4. Is 8/4 = 24/12 5. Is 8 1/2 in. By 10 5/8 in. And 6. Is 20 ft. As for 7 and 8, I’m not sure… Just turn to Brainly for those.
5. Is 81/2 in. by 10 5/8 in… Just to be clear- Also I thought 2 was 25, not 125-

Thank you for your help! :)
So the cars will reflect blue light, but since no blue light is being emitted, they won't look blue? Since yellow light is a combination of red and green light, no blue is involved. One will not be able to see the police cars??? Thank you for your help!!
Thank you!
You're welcome. If you think about it, it makes since why you got the same answer. The way you did it was right, just not the method they were asking for. There is never just one way to do things in math. :-)
Both sets of answers are correct. I only wonder if in the second one, you should have used the sq. root property. If you did it that way you would get the exact same answer. I just don't want you to get marked down for not following directions. here's how
Alright. I think I might have gotten the answer. Write back and tell me if you think it's right. If you think I messed up, I'll keep trying. First use ln to rearrange the original: 4^(x+4)=5^(2x+5) ln4^(x+4)=ln5^(2x+5) Put the exponents in front because of
9^(x - 9)/8= sqrt of 9 i got 13 Correct! ______________________ 4^(x + 10) = 8^(x - 6) i got 38 Correct! Here's my work: 4^(x+10)=(2^2)^(x+10) 8^(x-6)=(2^3)^(x-6) 2(x+10)=3(x-6) Distribute 2x+20=3x-18 -x=-38 x=38 ______________________ Solve the
Well for one thing, we know f(x) is equal to y. It is the original function. For f(x)=3x^2 -5 We want to find the y value when x=-4 So just plug in -4 for all the x's and get the y value. f(-4)=3(-4)^2-5 f(-4)=3(16)-5 f(-4)=48-5 f(-4)=43 f(-4)=43=the y
First you have to realize that: square root 12x^3/5 and (12x^3/5)^1/2 are equal! :-) Taking the square root of a value is the same as taking the value to the 1/2 power Use this rearrangement to simplify: (12x^3/5)^1/2 Multipy the exponents... 12x^3/10 I'm
Thanks for your help! :-) I think I got the answer! Thanks1
Allright. Thanks for your help! :-)

Thanks so much for all your help everyone. I really appreciate it. I think I've got it all figured out now.
I'm sorry, that just helped explain the plot. The problem is that I need to write 3 journals about this: 1- What does Pip learn in the first "expectation" of his life? How is this helpful to him, both at the time he learns it and later on in the novel? 2-
I think it might be "subtotatl". Check the vocab list in your book if there is one.
Sorry in advance-- I don't know how to find the answer, but I'm willing to help all I can. First, rearrange the equation of the line to make it y=-3x-1. Since we need to find a line parallel to this one, we know it needs a slope of -3. y=-3x-1 y=mx+b
If nights=n and she sleeps 8 hrs for every n... then you would need to multiply 8 by the number of nights to find the total amount of sleep she got. So X total hours of sleep=8n or x=8n

So I would write the Vertical Asy answer... x=0+(pi)n correct? since 180=pi and it can be added "n" number of times please let me know if this is the correct notation thanks so much for your help --Corin
Ooops, Sorry DrBob. I didn't realize you had already answered.
Try using PEMDAS to help you remember the order of operations. P-Parentheses E-Exponents M-Multiplication D-Division A-Addition S-Subtraction Do you have any parenthesis? No. Are there any exponents? No. Any Multiplication? Yes. Start there. -3*2x = -6x
I suggest trying to repeat after someone that does have a spanish accent. Listen to spanish music for starters. It's fun and when you sing along your accent is improving! :-) Audiobooks are also a good idea. I'm sure you will get better in no time. Buena
