Find an equation of the line perpendicular to y=4x+5 and that passes through the point (0,-1)

Mathematics

Answer:

y = -1/4x - 1.

Step-by-step explanation:

y = 4x + 5

The slope of this is 4 so the slope of line perpendicular to this line = -1/4.

Using the formula y - y1 = m(x - x1):

y - (-1) = -1/4(x - 0)

y + 1 = -1/4x

y = -1/4x - 1.

10(7k+9p+3) I don’t understand
Llana [10]

Answer:

4=0

Step-by-step explanation:

Simplifying

(-9p + 7) + -1(-9p + 3) = 0

Reorder the terms:

(7 + -9p) + -1(-9p + 3) = 0

Remove parenthesis around (7 + -9p)

7 + -9p + -1(-9p + 3) = 0

Reorder the terms:

7 + -9p + -1(3 + -9p) = 0

7 + -9p + (3 * -1 + -9p * -1) = 0

7 + -9p + (-3 + 9p) = 0

Reorder the terms:

7 + -3 + -9p + 9p = 0

Combine like terms: 7 + -3 = 4

4 + -9p + 9p = 0

Combine like terms: -9p + 9p = 0

4 + 0 = 0

4 = 0

Solving

4 = 0
