Jordan is using a number line to model the division expression -24 - 12. What should be a step in his work?
Draw a chain of bounces to the right, 12 units wide, starting at -24 and ending at 12.
o Draw a chain of bounces to the left, 12 units wide, starting at 0 and ending at -24.
Draw a chain of bounces to the right, 12 units wide, starting at 0 and ending at 24.
Draw a chain of bounces to the left, 12 units wide, starting at 24 and ending at 0.

Sry i’m so bad at math! wish i could answer #imdumb

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!

If this is the question f(x)= -x2 +4x-3 f(-1)= )2 +4 (-1)-3 =2-4-3 f(-1) =-5
