Y=2x2−8x+5 is standard form
Answer: it think its A
Step-by-step explanation:
77/8= 9.625 and 31/4= 7.75...so 9.625-7.75= 1.875
Answer:
y=4x-1
Step-by-step explanation:
4x-y=1
4x=y+1 then negative Y becomes positive after going to the other side of the equal sign.
4x-1=y the positive 1 becomes negative after going to the other side of the equal sign.
Answer:
Step-by-step explanation:
For #2, remember that 
, so 
Also, (a+b)(a-b), where a and b are any numbers, (a+b)(a-b)=
. Now, to simplify, or radicalize, a number with surds in the denominator, you have to multiply the denominator by its conjugate. If there is a complex number 
, where a and b are any numbers, the conjugate is always 
. Lets apply these rules. The conjugate of 4+6i is 4-6i, so do this:
Our answer is (28-3i)/(26)!
