What are all solutions to the differential equation dy/dx=sec^2*x ?

zysi [14]

Answer:

y=tanx+C

Step-by-step explanation:

$\frac{dy}{dx} = {sec}^{2} \: x \\ \\ dy = {sec}^{2} \: x \: dx \\ integrating \: both \: sides \\ \\ \int \:1\: dy = \int {sec}^{2} \: x \: dx \\ \\ \huge \red{ \boxed{ \therefore \: y = tan \: x + c}} \\$

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15

mafiozo [28]

Answer:

Step-by-step explanation:

Parallel lines have same slope.

y = mx + b

Slope = m & y-intercept = b

x - 5y = 15

-5y = -x + 15

y = $\frac{-1}{-5}x + \frac{15}{-5}\\\\$

$y = \frac{1}{5}x - 3$

so, slope = 1/5 ; (-5 , 7)

y -y1 = m(x -x1)

$y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8$

Answer:

1. 30

2. x<-72

3. 7b=63

4. x=3.2

5. 1/10

Step-by-step explanation:

1. Substitute a for 10

2(150/10)

2*15

2. Think of it like a normal equation

x/4<-18

x<-18*4

x<-72

3. 7b=63

4. 2.5x=8

x=3.2

5. 1/5*1/2= 1/10
