Answer:

Step-by-step explanation:

The equation of a circle in general form is

x² + y² + 2gx + 2fy + c = 0

Given

x² + (y + 1)² = 2 ← expand factor using FOIL

x² + y² + 2y + 1 = 2 ( subtract 2 from both sides )

x² + y² + 2y - 1 = 0 ← in general form

Y=-1/3x-.75

why:
y-intercept is -.75 five or take.
slope is down 1, over 3
since line (going left to right) is going down, it’s negative

Which of the following sets contain all roots of the polynomial

Zarrin [17]

All these given roots are contained in option C.

The given equation is :

$9x^{3}+9x^{2}-4x-4=0$

$9x^{2}(x+1)-4(x+1)=0$

$(9x^{2}-4)(x+1)=0$

$9x^{2}-4=0,x+1=0$

$x^{2}=\frac{4}{9},x=-1$

$x=\frac{2}{3},x=-1$

Roots = $-1,\frac{-2}{3} ,\frac{2}{3}$

Hence these lie in between $(\frac{-3}{2} ,\frac{3}{2})$

irina [24]

Answer:

x = -12

Step-by-step explanation:

First, you want to plug in f(x)'s value into the equation.

-2 = -x-14

Then solve for x:

x=-14+2

x=-12

Jonathan has a collection of 400 marbles. Blue makes up 17% of his collection,how many blue marbles does Jonathan have?

Yuki888 [10]

So percent means parts out of 100 so 17%=17/100
400 marbles
17% of 400=blue
'of' can be translated to multiply
17%=17/100
17/100 ties 400=6800/100=68
he has 68 blue marbles

For a fixed amount of a gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. At a pre

Veronika [31]

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

x-------> the pressure in PSI

y------> the volume of the gas in cubic inches

In this problem we have the point $(30,600)$

$x=30\ psi\\y=600\ in^{3}$

Find the constant k

$y*x=k$

substitute the values of x and y

$600*30=k$

$k=18,000\ lb*in$

the equation is

$y=18,000/x$

therefore

<u>the answer is</u>

$y=18,000/x$
