I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12

3 − 1 = 5 + 10 = −5 1/2 Check whether the given value of is a solution to the equation. Justify your answer.

andrey2020 [161]

Answer:

$x = -5\frac{1}{2}$ is the solution

Step-by-step explanation:

Given

$3x - 1 = 5x + 10$ --- Correct expression

$x = -5\frac{1}{2}$

Required

Determine if the given solution is correct

To do this, we simply solve for x in the given equation.

So, we have:

$3x - 1 = 5x + 10$

Collect like terms

$3x - 5x = 1 + 10$

$-2x = 11$

Divide both sides by -2

$\frac{-2x}{-2} = \frac{11}{-2}$

$x = -\frac{11}{2}$

$x = -5\frac{1}{2}$

What’s the differential equation of

worty [1.4K]

Answer:

$y=\frac{1}{x^{2}-6x+13 }$

Step-by-step explanation:

We have given,

$\frac{dy}{dx}=y^{2}(6-2x)$

and initial condition $x=3,\ y=\frac{1}{4}$

Now,

$\frac{dy}{dx}=y^{2}(6-2x)$

Rearranging the variables, we get

$\frac{dy}{y^{2} }=(6-2x).dx$

Applying integration both sides, we get

$\int\ {\frac{dy}{y^{2} } } \,=\int\ {(6-2x).} \, dx$

⇒ $\frac{-1}{y} =6x-\frac{2x^{2} }{2}$

⇒ $\frac{-1}{y}=6x-x^{2} +C$

Putting the initial condition (i.e., $x=3,\ y=\frac{1}{4}$ ), we get

⇒ $-4=6\times3-(3)^{2}+C$

⇒ $-4=18-9+C$

∴ $C=-13$

We have, $\frac{-1}{y}=6x-x^{2} +C$

now putting the value of $C$ in above equation, we get

⇒ $\frac{-1}{y}=6x-x^{2} -13$

⇒ $\frac{1}{y}=-6x+x^{2} +13$

$y=\frac{1}{x^{2}-6x+13 }$

Rick is buying a $115 tennis racquet from a sporting goods store. If the racquet is on sale for 35% off and sales tax is 8%, how

lapo4ka [179]

Answer:

$80.73

Step-by-step explanation:

115 * 0.35 = $40.25 off

115 - 40.25 = $74.75 after sale

add tax (0.08)

74.75 * 0.08 = $5.98 tax

74.75 + 5.98 = $80.73 in total
