A-8x+12
B-6(2x+3)
C-5(2+3x)
y= -4x² - 16x - 14
Take the coefficient of x² as the common factor
y = - 4(x² + 4x + 7/2)
Add (b/2)² to complete the square
y = - 4( x² + 4x + 2² - 2² + 7/2)
Complete the square
y = -4( (x + 2)² - 1/2)
Remove the bracket
y = -4(x + 2)² + 2
Answer: y = -4(x + 2)² + 2
Answer:
its b
Step-by-step explanation:
step 1
Find the slope of the given line
we have
y=(2/3)x+4
the slope is m=2/3
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal
so
the slope of the perpendicular line to the given line is
m=-3/2
step 2
Find the equation of the line in slope intercept form
y=mx+b
we have
m=-3/2
point (-2,5)
substitute
5=(-3/2)(-2)+b
solve for b
5=3+b
b=2
therefore
<h2>y=-(3/2)x+2</h2>
Answer:
Step-by-step explanation:
Respectively we will say the book has One thousand pages (1000) . Now we find 1/4 of a 1000 which is 250 , then we find 1/5 of a 1000 which is 200. Now we add them together which is 250+200=450 . 450 / 1000 = 9/20 which is about a half
