Find the x-intercept of parabola with vertex (1,-17) and y-intercept (0,16)?
Ad libitum [116K]
Y=a(x-1)^2 -17 is the equation of the parabola.
at (0,16), 16=a(0-1)^2 -17.  Solve for a = 33.
Equation is then y=33(x-1)^2-17 so when y=0,
(x-1)^2 = 17/33
x-1 = + and - square root of 17/33
x = 1.7177 and 0,2823 as the intercepts

Find parametric equations and symmetric equations for the line of intersection of the given planes. x + y + z = 5, x + z = 0
oee [108]

The next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .

What is the meaning of parametric and non parametric?

  • The assumptions behind parametric statistics relate to the population's distribution from which the sample was drawn.
  • Since no presumptions are made while using nonparametric statistics, data can be gathered from samples that do not fit any particular distribution.

x + y + z = 5, x + z = 0

the line satisfies

x + z = 0 , y = 5

thus

x = t, y = 5 and z = -t .

the first one is technically already the symmetric equations of the line.

thus:

x = -z ; y = 5

the next set is the parametric equations of the same line .

x = t, y = 5 and z = -t .

What is the value of x=2x + 9 = -27
Sergio039 [100]
<h3>I'll teach you how to solve 2x + 9 = -27</h3>

-----------------------------------------------------

2x + 9 = -27

Subtract 9 from both sides:

2x+9-9 = -27-9

SImplify:

2x=-36

Divide both sides by 2:

2x/2 = -36/2

Simplify:

x= -18

Your Answer Is x= -18

plz mark me as brainliest if this helped :)
