|dw:1333480698850:dw| Plug the given values into the variables and solve! :D
IS ANSWER -13 ?
|dw:1333480809834:dw| Yes!!! :D
I GOT 13 BUT DONT NO IF ITS POSTIVE OR NEG
CAN U HELP ME WITH THIS ONE
It's negative! -10 - 3 is like adding a negative. It's easier to think of it that way, I think
[1.03] Evaluate the following expression using the values given. Find 2x − 3y if x = 2 and y = −4 8 −8 −16 16
You just do the same thing! Plug the given numbers into the variables and see what you get :)
I GOT 8 BUT I THINK ITS POSTIVE
Remember that negative signs cancel out, so -3 times -4 is positive twelve!|dw:1333480967382:dw|
WHAT ABOUT THIS ONE , THANXS SOO MUCH Translate the following phrase into an algebraic expression: Two times the sum of a and b 2a + b a + 2b 2a + 2b 2(a + b)
"times" means multiplication, and "sum of" means that you add a & b. Which one do you think it is?
I THINK ITS C
It's D, because when it says "two times the sum of" then you know it should the "sum of" in parenthesis. :D
THANX SOO MUCH (IS THIS ONE C) ] Use the distributive property to simplify the expression below: −3(3d − 1) + 5d −4d + 3 −4d − 3 −d + 3 −d − 3
but wait could it be a because 2times the sum of a and b
WHAT ABOUT THIS ] Use the distributive property to simplify the expression below: −4(2u − 4) −6u − 4 −6u + 8 −6u − 16 −8u + 16
The other is D, not A. It's D because when it says "times the sum of" then you know it should be one number being multiplied by the sum of two numbers. When a number is being multiplied by the sum of something, those numbers have to be added first. Therefore they should go in the parenthesis to be added first then multiplied.
Can you show your work for that one? Where are you getting stuck?
ohhhh ok i got :)
−4(2u − 4)
is -8u+16 right?
Simplify the following expression. 2x − 2y + 3z − 2x − y + 2z = ? 4x − 3y + 5z −2y − 3y + 5z −2x − 3y + 6z −3y + 5z
YES I THOUGHT IT WOULD BE THAT BUT WASNT FOR SURE
well you have to combined like terms
Why don't you show us your work & we can tell you if it's right?
well i think is answer D but im not sure
|dw:1333482170929:dw| This might help, remember that the sign before a number goes with it.
so that is going to equal 0 because if u add a 2x-2x =0
|dw:1333482424028:dw| Yes, they'd cancel out. I really hope @cvasdcv is gettin' this :p
me 2 i hope this help that we are talking about every step
so a -2y-y=-3
