what is the equation of the line in point slope form that goes through (-2,-1) and is perpendicular to y=5x+3?

stich3 [128]

Point slope form is $y-y1=m(x-x1)$

Since we have to write the equation of a perpendicular line we will have to use the slope that is opposite and reciprocal.

$y - (-1) = - \frac{1}{5} (x - (-2))$
$y + 1 = - \frac{1}{5} (x + 2)$

Hope this helps :)

How to solve 2a x a x a x3a + b +4b

kodGreya [7K]

Answer:

$6 {a}^{4} + 5b$

Step-by-step explanation:

$2a \times a\times a \times 3 a+ b + 4b \\ 2a \times a = 2 {a}^{2} \\ 2 {a}^{2} \times a = 2 {a}^{3} \\ 2 {a}^{3} \times 3a = 6 {a}^{4} \\b + 4b = 5b$
