Answer:

Try coplanar, line

Step-by-step explanation:

Two lines are parallel lines if they are coplanar and do not intersect. Lines that are not coplanar and do not intersect are called skew lines. Two planes that do not intersect are called parallel planes.

Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)
Mila [183]

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Step-by-step explanation:

Given equation of line is:

y=-0.75x

The coefficient of x is the slope of the line so the slope of given line is: -0.75

As parallel lines have equal slopes so the required equation of line will have the same slope.

The slope-intercept form is:

y = mx+b

Putting the value of the slope

y = -0.75x+b

To find the value of b, putting the point in the equation

0 = -0.75(8)+b\\0 = -6+b\\b = 6

Putting the values of m and b, we get

y = -0.75x-6

Hence,

Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Ƒ(x) = x2 + 2x − 15 to find the solution when ƒ(x) = 0.
lozanna [386]

Answer:

f = 2 + -15x-1 + x

Step-by-step explanation:

Simplifying

f(x) = x2 + 2x + -15

Multiply f (x)

fx = x2 + 2x + -15

Reorder the terms:

fx = -15 + 2x + x2

Solving

fx = -15 + 2x + x2

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -15x-1 + 2 + x

Simplifying

f = -15x-1 + 2 + x

Reorder the terms:

f = 2 + -15x-1 + x
