Better yet, let y = 6 and solve for x.
6 = x^2 –2x + 5
Now solve for x.
14/20 21/30 28/40 are the equivalent fractions
Answer:
Step-by-step explanation:
You can tell by looking at the form of each equation.
y = tx
This is a straight line that passes through the origin, so it symmetric with respect to the origin.
y = x²+1
This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.
y = x²+x = (x+½)² - ¼
This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
Can't tell what "y = (1 + x2)3" means. Which terms are exponents?
√ab=(√a)(√b)
find perfect squares
√50=(√25)(√2)=5√2
answer is A
Answer:
5.25 + 2.50 = 7.75. 10 - 7.75 =2.25
