Answer: Because the graphs of the two equations overlap each other
Step-by-step explanation:
Every point on the first line also satisfies the second equation.
This is the same as equivalent fractions
where 1/2 = 2/4 = 3/6 = 4/8
Graphing these on a number line would only show one dot.
Answer:
C.
Step-by-step explanation:
We can off-the-bat eliminate choices A and B, because the first part of the quadratic formula is a -b. Therefore, the value for b in the quadratic has to be a positive, because the value in the formula is negative. This leaves us with choices C and D. If you look at the discriminant, you will see that our <em>a </em>in the quadratic formula is 3, so your answer choice is C.
Step-by-step explanation:
Answer is B but what kind of question is this? You don't even have to find the equation just find which one is different from the others.
A) y+2 = 4x-4
y = 4x-6
B)y-2 = 4x+4
y= 4x+6
C)y = 4x-6 (same with A )
D)y-6 = 4x-12
y= 4x-6 (Same with A and C)
So b is the different one.
f(x)=9x²+24x+1
f(x)=(3x)²+ 2×3x× 4 + 1
= (3x)²+2×3x×4 +16 -16 +1
=. ( 3x+4)² -15. -------(1)
then (3x+4)² ≥0
least value of (3x+4)² is 0
putting in equation 1
= 0-15 =-15
- 15 is the least value
