Answer:

So the answer is (7+\frac{1}{7} )\times (7+7)=100

Step-by-step explanation:

Given,

Using 7 four times and 1 one time getting to  100

If we are write this way then easily get the answer;

(7+\frac{1}{7} )\times (7+7)

Add together 7+\frac{1}{7} by making a common denominator of  7 and also add (7+7) in the second set of parenthesis to yield 14

(\frac{49+1}{7} )\times 14

\frac{50}{7} \times 14

50\times 2   (By Cross-reduce and multiply the fractions)

100

∴ (7+\frac{1}{7} )\times (7+7)=100

Find dydx for xy+x+y=6. Differentiate both sides of the equation with respect to x, and then solve for dydx. Do not substitute f
velikii [3]

Answer:

\frac{dy}{dx}=-\frac{y+1}{x+1}

Step-by-step explanation:

The given equation is xy+x+y=6

Differentiate both sides with respect to x

x\frac{dy}{dx}+y+1+\frac{dy}{dx}=0

Take y and 1 to other sides of the equation

x\frac{dy}{dx}+\frac{dy}{dx}=-y-1

Factor out dy/dx from the left hand side of the equation

\frac{dy}{dx}(x+1)=-y-1

Divide both sides by (x+1)

\frac{dy}{dx}=\frac{-y-1}{x+1}\\\\\frac{dy}{dx}=-\frac{y+1}{x+1}

Answer:

\large\boxed{x=-\dfrac{44,475}{64}}

Step-by-step explanation:

-4\sqrt[3]{x+25}=35\\\\\left(-4\sqrt[3]{x+25}\right)^3=35^3\\\\-4^3(x+25)=42,875\\\\-64(x+25)=42,875\qquad\text{use distributive property}\\\\-64x-1,600=42,875\qquad\text{add 1,600 to both sides}\\\\-64x=44,475\qquad\text{divide both sides by (-64)}\\\\x=-\dfrac{44,475}{64}

HELP!!!!
OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here.  It's very simple to follow:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

which, for us, looks like this:

d=\sqrt{(13-4)^2+(19-7)^2} and

d=\sqrt{9^2+12^2} and

d=\sqrt{81+144} and

d=\sqrt{225} so

d = 15
