The first step to getting this in vertex form would be to put this in proper standard form. This is so that you can split the middle term which is a step of completing the square.

Softa [21]

Answer:

34;34;112

Step-by-step explanation:

It's a Isosceles triangle so the equation is

x+17=4x-34

x-4x=-35-17

-3x=-51

x=-51/-3

x=17

17+17=34

4.17-34=34

6.17+10=112

A cone has a diameter of 18 in. and a height of 14 in.
Bond [772]
Cone's volume is V =  \frac{1}{3}Sh
where    S - surface area,  h - height
Surface area =  \pi r^2

r = 18/2=9
h= 14
π = 3.14
V= \frac{1}{3}  \pi r^2h= \frac{1}{3} *3.14*9^2*14= \frac{1}{3} *3.14*81*14=27*14*3.14[/tex]
V = 1186.92 in.^3

Find an equation parallel to the line, y= -3x -1
Aleks04 [339]

Answer:

y = 3x -2

Step-by-step explanation:

If the line is parallel, that means it has the same slope. The given equation had a slope of 3, so the new line must also have a slope of 3.

You can plug the given coordinates into the slope-intercept form with a slope of 3 to find your answer.

y = m*x + b

7 = 3*3 + b

7 = 9 + b

-2 = b

y = 3x -2

I Hope This Helps :D
