Answer:

x = 9

Step-by-step explanation:

Firstly, you have to balance the equation.

Start by subtracting 0.5 from both sides. Remember, when solving algebraic equations such as this one, you use reverse PEMDAS, or SADMEP.

Now, you have 0.5x = 4.5

Now, for the next step: division. Divide both sides by 0.5, or in other words, multiply by 2.

x = 9

Hope that helps! Please don't hesitate to contact me if you have any questions :)

5 9

(x - (—— • x)) - — = 0

10 2

Simplify 1/2

1 9

(x - (— • x)) - — = 0

2 2

x = 9

4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this

Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

$4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)$

Multiply eq(2) with 4 and subtract with eq(1)

$4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8$

So, value of y=8

Now, finding value of x by putting value of y in equation 2

$x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1$

So, value of x = -1

value of x = -1 and value of y=8

Set up, but do not evaluate, the integral that represents the length of the curve given by

netineya [11]

Answer:

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Step-by-step explanation:

Arc length of a parametric curve is:

L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = t + cos t, dx/dt = 1 − sin t

y = t − sin t, dy/dt = 1 − cos t

L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt

Or, if you wish to simplify:

L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt

L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt
