Answer:
2x + 3
Step-by-step explanation:
Given
(x² + 7x + 1) + (- x² - 5x + 2) ← remove parenthesis
= x² + 7x + 1 - x² - 5x + 2 ← collect like terms
= 2x + 3
Answer:
b could be -1 or 0
Step-by-step explanation:
f(x) = 3x^2 +bx+2
if it has no real roots, the discriminant must be less than zero
b^2 -4ac <0
a=3 b=b c=2
b^2 - 4(3)(2) <0
b^2 - 24 <0
b^2 < 24
Taking the square root of each side
b< 2 sqrt(6) and b > 2 sqrt(6)
b could be -1 or 0
Answer:
-i
Step-by-step explanation:
3i-4i=-i
Answer:
2 cups of flour : 1 cup of shortening
Step-by-step explanation:
So lets gather our information.
We know it takes 6 cups of flour for the reciepe.
We also know it takes 3 cups of shortening.
To find the ratio, put the two number values in a fraction:
cups of flour/cups of shortening
=
6/3
This says for 6 cups of flour, there are 3 cups of shortening
We can simplyfy this to:
2/1
This says for 2 cups of flour, there is 1 cup of shortening.
<u>Answer:</u>
<u>2/1</u>
