We are given
a parabola has an axis of symmetry at x = -5, a maximum height of 9
so, we get
vertex =(-5,9)
vertex=(h,k)=(-5,9)
so, h=-5 and k=9
we can use vertex form of parabola
we can plug these value
now, it passes through the point (-7,1)
we can use it and then we can solve for a
So, we will get equation of parabola as
..............Answer
Given: A= 52ft² and l= 2w-5
know that formula for A= lw, substitute for what you know and solve for w
52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft
now input that in the equation for length and solve for l:
l=2w-5=2(6.5)-5=8
so the length is 8 ft
A paralell line has same slope
the equation of a line with slope of m and passing through point (x1,y1) is
y-y1=m(x-x1)
we are given
y-3=-1(x+1)
slope=-1
we don't need the point
we want it to pass through (4,2)
x1=4
y1=2
y-2=-1(x-4)
trish is right
solve for y
y-2=-x+4
y=-x+6
both are correct
It’s d, 1 - t
t + 3 - 2 - 2t
we can rearrange it as
t - 2t + 3 - 2
-t + 1 is the same as 1 - t
