Solve Q²= a(p²-b²)/p in form of y=mx+c

umka2103 [35]

Answer:

We want to rewrite:

q^2 = a*(p^2 - b^2)/p

as a linear equation, in the form:

y = m*x + c

So we start with:

q^2 = a*(p^2 - b^2)/p

we can expand the left side to get:

q^2 = (a/p)*p^2 - (a/p)*b^2

q^2 = a*p - (a/p)*b^2

Now we can ust define:

a*p = c

Then we can replace that to get:

q^2 = -(a/p)*b^2 + c

now we can replace:

q^2 = y

b^2 = x

Replacing these, we get:

y = -(a/p)*x + c

finally, we can replace:

-(a/p) = m

then we got the equation:

y = m*x + c

where:

y = q^2

x = b^2

c = a*p

m = -(a/p)

Someone pls help me ! i rlly need help

DerKrebs [107]

Answer:

Option D is the correct answer.

Step-by-step explanation:

Coefficients od dividend = (4, - 17, - 15)

Dividend $=4x^2 - 17x - 15$

Divisor x = 5 =>x-5= 0

Coefficients of Quotient = (4, 3)

Quotient $=4x + 3$

Remainder = 0

Since,

$Dividend = Divisor \times quotient + Remainder\\\therefore 4x^2 - 17x - 15 = (x - 5)\times (4x + 3) +0 \\\therefore 4x^2 - 17x - 15 = (x - 5)\times (4x + 3) \\\therefore( 4x^2 - 17x - 15) \div (x - 5) = (4x + 3)$

Oh freight elevator can hold a maximum weight of 3500 pounds and delivery man weighs 200 pounds is delivering curtains that each

mario62 [17]

Answer:

$200+48n\leq 3500$

$n\leq 66.7$

Step-by-step explanation:

The freight elevator can hold a maximum weight of 3500 pounds
The delivery man weighs 200 pounds
Each carton weighs 48 pounds

Let the number of cartons he can safely put on the elevator at one time=n

Total weight of Carton=48n

Since the weight of the man and the cartons combined must not be more than 3500 pounds,

Therefore,an inequality that represents the situation is:

$200+48n\leq 3500$

We can solve for n if required

$200-200+48n\leq 3500-200\\48n\leq 3200\\\text{Divide both sides by 48}\\n\leq66.7$

The delivery man can safely carry 66 Cartons.
