Step-by-step explanation:
the first is
2(x - 1/2)² = 2(x² - 2×1/2×x + 1/4) = 2x² - 2x + 1/2
so, no, this is not the same.
the second is
2(x - 1/4)² = 2(x² - 2×1/4×x + 1/16) = 2x² - x + 1/8
that is the correct answer.
the third is
2(x - 1/8)² = 2(x² - 2×1/8×x + 1/64) = 2x² - 1/2 x + 1/32
so, no, this is not the same.
the fourth is
2(x - 1/16)² = 2(x² - 2×1/16×x + 1/256) = 2x² - 1/4 x + 1/128
so, no, this is not the same.
1. 0.5x+3.5
Slope: 0.5
y-intercept: (0,3.5)
x: (-7,0)
y: (0,3.5)
Answer:
-9
Step-by-step explanation:
with the equation y=mx+b, m equals the slope and b equals the y-intercept. whatever is in the place of m is the slope. in this case, -9.
Answer:
Step 1: 4
Step 2: 4 and 1
Step 3: 2x² + 4x + x + 2
Step 4: (2x² + 4x) + (x + 2)
Step 5: 2x(x + 2) + 1(x + 2)
Step 6: (x + 2)(2x + 1)
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
From the given venn diagram it is clear that
Since the intersection of A and B is non-empty, therefore by conditional probability
Therefore, the correct option is B.
