Answer:
y=-7
Step-by-step explanation:
y-3=-2(x+5)
distribute the -2 into the ( )
y -3= -2x -10
cancel to -2x
y- 3 = -2(0) -10
y-3 = -10
+3 +3
y= -7
Hope this helps!!
The first option: 2x^2+2x-4 since there are three terms
I believe it is an acute triangle
but I also am confused on this one
Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form
