Answer:

81

Step-by-step explana81tion:

Square root of x minus 5 plus 7 = 11

√x-5+7=11

√x+2=11

√x=11-2

√x=9

squaring both sides to remove the root from x

(√x)²=(9)²

√x ×√x is x and 9×9 is 81

so you will get,

x=81

hope it helps you

A line passes through the points (4,-4) and (8,12). What is the y-intercept of the line ?
fredd [130]
\frac{y2-y1}{x2-x1}= \frac{y-y1}{x-x1} = \frac{12-(-4)}{8-4}= \frac{y-(-4)}{x-4}
\frac{16}{4}= \frac{y-(-4)}{x-4 }  
= 4(x-4)=(y+4)
4x-16=y+4

4x=y+4+16
4x=y+20
y=4x-20

Find the vertex, focus, directrix, and focal width of the parabola: -1/40x^2=y
dimulka [17.4K]
For
(x-h)^2=4p(y-k)
vertex is (h,k)
distance from vertex to directix=p=distance from vertex to focus
|4p|=focal width

remember, focus is on the side of the parabola where it opens and directix is at the back
when p is negative, it opens down
when p is positive, it opens up

look at equation
-1/40(x-0)^2=(y-0)
times -40 to both sides
(x-0)^2=-40(y-0)
(x-0)^2=4(-10)(y-0)
vertex=(0,0)
p=-10,it's negative so it opens down

focus is 10 units below vertex (y direction)
focus=(0,-10)

diretix is 10 above
directix is y=10

focal width=|4p|=|4(-10)|=|-40|=40




vertex=(0,0)
focus=(0,-10)
directix is y=10
focal width=40 units
