Solve. −x2 = 2x − 15

Mathematics
1 answer:
Fynjy0 [20]3 years ago
5 0

Answer: X= 15/4

Step-by-step explanation:

Subtract 2x from both sides

-x 2-2x=2x-15-2x

Simplify

-4x=-15

Divide both sides by -4

4x/-4 = -15/-4

Simplify

X=15/4

Write parametric equations of the line through the points (7,1,-5) and (3,4,-2). please use the first point as your base-point w
Roman55 [17]

Given:

A line through the points (7,1,-5) and (3,4,-2).

To find:

The parametric equations of the line.

Solution:

Direction vector for the points (7,1,-5) and (3,4,-2) is

\vec {v}=\left

\vec {v}=\left

\vec {v}=\left

Now, the perimetric equations for initial point (x_0,y_0,z_0) with direction vector \vec{v}=\left, are

x=x_0+at

y=y_0+bt

z=z_0+ct

The initial point is (7,1,-5) and direction vector is \vec {v}=\left. So the perimetric equations are

x=(7)+(-4)t

x=7-4t

Similarly,

y=1+3t

z=-5+3t

Therefore, the required perimetric equations are x=7-4t, y=1+3t and z=-5+3t.
