Passes through (4,3) slope = 2
y - y1 = m(x - x1)
y - 3 = 2(x - 4)
y - 3 = 2x - 8
y = 2x - 5
C
Answer:
2(x + 2)² - 5
Step-by-step explanation:
Given
2x² + 8x + 3
To obtain the required form use the method of completing the square.
The coefficient of the x² term must be 1, thus factor 2 out of 2x² + 8x
= 2(x² + 4x) + 3
add/subtract ( half the coefficient of the x- term)² to x² + 4x
= 2(x² + 2(2)x + 4 - 4) + 3
= 2(x + 2)² - 8 + 3
= 2(x + 2)² - 5
with p = 2 and q = - 5
Answer:
y=4x + 3/4
Step-by-step explanation:
By definition, the number
is the ratio between the circumference and the diameter:

This implies that

And so your circumference is
