Write a equation of the lines passes through the given points (-2,7) (1,1) the equation is?

vredina [299]

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

The formula of a slope:

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

We have the points (-2, 7) and (1, 1). Substitute:

$m=\dfrac{1-7}{1-(-2)}=\dfrac{-6}{3}=-2$

$y-7=-2(x-(-2))\\\\\boxed{y-7=-2(x+2)}$ point-slope form

$\boxed{y=-2x+3}$ slope-intercept form

$\boxed{2x+y=3}$ standard form

Hello there! :)

Answer:

$\boxed{b>8}\checkmark$

<h2>*****The answer should have a GREATER THAN SIGN AND POSITIVE TOO!*****</h2>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

PEMDAS

Order of operations

Parenthesis

Exponent

Multiply

Divide

Add

Subtract

Left/Right

First, you add by 4 from both sides of an equation.

$b-4+4>4+4$

Then, you add numbers from left/right.

4+4=8

$\boxed{b>8}$ , which is our final answer.

Hope this helps you!

Have a nice day! :)

Answer: B

The diameter is 3, so you have to divide by 2 to get the raduis. After that just plug in the height and radius and that's your answer!

Hope this helped you!

Multiply? I don't know how to do this o.o (X+4√2) (x-4√2) (x-3i)

Korolek [52]

Answer:

$x^{3} -(3i) \; x^{2} -32x + 96 i$ .

Step-by-step explanation:

Notice that the first two factors are in the form $(x-a)(x+a)$ , which is equal to $(x^{2} - a^{2})$ . Start by combining and expanding these two factors:

Let $a = 4\sqrt{2}$ .

$a^{2} = 16 \times 2 = 32$ .

$(x + a) (x - a) = x^{2} - a^{2} = x^{2} -32$ .

This expression can now be expressed as $(x^{2} - 32)(x - 3i)$ . $i$ stands the unit imaginary number, where $i^{2} = -1$ . Unless $i$ is raised to a certain power other than $1$ , it can be treated just like a constant.

Expand this expression using FOIL:

$\begin{aligned}&(x^{2} - 32)(x - 3i)\\=&\underbrace{x^{2}\cdot x}_{\verb!F!} +\underbrace{(x^{2})(-3i)}_{\verb!O!} + \underbrace{(-32)x}_{\verb!I!} + \underbrace{(-32)(-3i)}_{\verb!L!}\\=& x^{3} -(3i)x^{2}-32x + 96i \end{aligned}$ .
