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
