Write an equation of the line that passes through (2, -3) and is perpendicular to the line y=-2x-3

Natalija [7]

Answer:

$y=\frac{1}{2} (x-2)-3$ or $y=\frac{1}{2} x-4$

Step-by-step explanation:

The perpendicular slope is the opposite-reciprocal of the original slope:

Perpendicular slope of -2 is $\frac{1}{2}$

Write the equation in point-slope form ( $y=a(x-h)+k$ ):

$y=\frac{1}{2} (x-2)-3$

Convert to slope-intercept form if needed:

$y=\frac{1}{2} x-1-3$

$y=\frac{1}{2} x-4$

zhannawk [14.2K]

Answer:

hello your question is incomplete attached below is the complete question

answer :

for I1 = $\frac{1}{x^2} + \frac{4}{x^3}$ The integral converges

for I2 = $\frac{2x + 6}{2(x^2 + 6x + 4 )}$ The integral diverges

for I3 = $\frac{1}{x^2}$ The integral converges

for I4 = 1 The integral diverges

Step-by-step explanation:

The similar integrands and the prediction ( conclusion )

for I1 = $\frac{1}{x^2} + \frac{4}{x^3}$ The integral converges

for I2 = $\frac{2x + 6}{2(x^2 + 6x + 4 )}$ The integral diverges

for I3 = $\frac{1}{x^2}$ The integral converges

for I4 = 1 The integral diverges

attached below is a detailed solution
