Answer:

Your answer would be number 4, "A and D"

Step-by-step explanation:

I already know that if you multiply a number by less than 1 it will give a product less than the original number so that makes B and C not the correct answer leaving a and d

I hope this helps :D

A positive real number is 6 less than another. If the sum of the square of the two numbers is 38, then finds the numbers.

Serggg [28]

Answer:

There seems to be a typo error but still this has solution.

Let the number be = x

A positive real number is 6 less than another. Means the second will be $(x+6)$

The sum of the square of the two numbers is 38.

$x^{2} +(x+6)^{2} =38$

=> $x^{2} +36+12x+x^{2} =38$

=> $2x^{2}+12x+36 =38$

=> $2x^{2}+12x=2$

=> $2x^{2}+12x-2=0$

Taking out 2 common;

=> $x^{2}+6x-1=0$

Solving this quadratic equation, we get;

$x=-3+\sqrt{10}$ and $x=-3-\sqrt{10}$

As positive number is needed, we have $-3+\sqrt{10}$

or x = $\sqrt{10}-3$

x = 0.162277

And other number is 6.162277.

What is the slope of the line passing thtough the points A(7, -6) and B(-4, -3)?

adelina 88 [10]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(7, -6) and B(-4, -3). Substitute:

$m=\dfrac{-3-(-6)}{-4-7}=\dfrac{3}{-11}=\boxed{-\dfrac{3}{11}}$

What are the values that make x^2 + bx + 64 a perfect square?

spayn [35]

Answer:

b = ±16

Step-by-step explanation:

Normally to find the number we add to make it a perfect square

We take the coefficient of x

Divide by 2

b/2

Then square it

(b/2) ^2

In this case, we are adding 64

(b/2) ^2 = 64

Take the square root of each side

sqrt((b/2) ^2) = sqrt(64)

b/2 = ±8

Multiply each side by 2

b/2*2 = ±8 *2

b = ±16
