The question wants us to solve for the variable y so we are only going to solve for the variable y. Start by having all the terms with the variable you want to solve for on one side of the equation and the rest of the terms on the other side of the equation.

<h2><u>Solving for y.</u></h2>

1. Subtract 5x from both sides of the equation to keep the variable you are solving for, y, on the left side of the equation.

<h3>-4y = -4 - 5x</h3>

2. Now to finish solving for the variable y, you want to isolate y by performing the opposite of multiplication: division. Divide both sides by -4 to isolate and solve for y.

<h3>y = 1 + 5/4x</h3>

There's your answer. Hope this helped you! Please comment below if you have any further questions.

Step-by-step explanation:

f(x)=(x-5)(5x +2)=0

=> x=5 or, x=-2/5

Diff Eq dy/dx= (ycos(x))/(1+y^2) initial condition is y(0)=1 work below ...?
Volgvan
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2

Solve: -4x-8x+17=23<br> check solution
Sveta_85 [38]

Answer:

x = -1/2

Step-by-step explanation:

To solve the equation, we first need to combine like terms:

-12x+17=23

Simplify further:

-12x=6

Divide by -12 on both sides to get:

x = -\frac{1}{2}

To check  the solution, plug x back into the original equation and check if we get the correct answer:

-4(-\frac{1}{2})-8(-\frac{1}{2})+17=23

2+4+17= 23

23=23

Thus, it checks out and our answer is correct.

Rearrange y=1/2x+2 to make x the subject.
yarga [219]

Subtract 2

y-2=1/2 x

Multiply by 2 to cancel out the denominator and to get 1 in front of x

2(y-2)=x

You can stop there or you can multiply out.

2y-4=x

Which function has a domain of {all real values of x : x does not equal 1)? **Hint: Graph the function and look for an asymptote
nikitadnepr [17]
Uhhh… this is a bad question. Because technically, none of those is the true correct answer. However, the only answer that it COULD be is B. If you were to plug in 1 into B, you’d get 0 in the denominator which creates an asymptote in the graph. None of the other three have this property

(Just a side rant, the reason none of them are technically correct is because x cannot equal -1 either… just some bonus points you could redeem with your teacher if you feel like it)
