If y=-8 when x=-2,find x when y =32

Mathematics
1 answer:
lidiya [134]3 years ago

So when y=32 it is 4x more than the original y which means they've multiplied it by four. Whatever you do to one you have to do to the other side so you multiply 2 by 4 to get 8 so x=8

Hi my lil bunny!

-6*f(-3)-5*g(-7)

Steps : <u>3</u>

Apply rule : - (-a) = a

= 6f * 3 + 5g * 7

Multiply the numbers : 6 * 3 = 18

= 18f + 5 * 7g

Multiply the numbers : 5 * 7 = 35

= 18f + 35g

1. Consider the function f(x) = 5x^3 - 31x^2 - 129x + 27
NeX [460]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

1.- f(x) = 5x³ - 31x² - 129x + 27

a) f(9) = 5(9)³ - 31(9)² - 129(9) + 27

   f(9) = 5(729) - 31(81) - 1161 + 27

   f(9) = 3645 - 2511 - 1161 + 27

   f(9) = 0

b.- I will use synthetic division

                        5   - 31  -129  + 27       9

                               45   126  -27                            

                        5     14     -3       0

    Trinomial = 5x² + 14x - 3

Factor               5x² + 15x - 1x - 3

                        5x(x + 3) - 1(x + 3)

b)                           (x + 3)(5x - 1)

                       x₂ + 3 = 0          5x₃ - 1 = 0

                       x₂ = -3                 x₃ = 1/5

c) The roots are x₁ = 9, x₂ = -3 and x₃ = 1/5

2.-  f(x) = 3x² + 2x - 8      factor = 3x - 4

                                     x    + 2

                       3x - 4    3x² + 2x - 8

                                   -3x² + 4x

                                     0    +6x - 8

                                           -6x  + 8

                                                      0  Remainder

As the remainder was "0", 3x - 4 is a factor of 3x² + 2x - 8

What are the center and radius of the circle defined by the equation ?
RUDIKE [14]
You didn't give us the equation, but circle equations are in the form;
(x-h)^2 + (y-k)^2 =r^2 where h and k are the x and y coordinate of the center and r is the radius of the circle squared.

Pls help me with this
sergij07 [2.7K]

Answer:

x=630

Step-by-step explanation:

The Exponential Product rule tells us that...

x^m*x^n=x^{m+n}

Therefore, x=1+2+3...+35.

Therefore, x=630

I need help like RN!!!<br> what are the foci of the ellipse? graph the ellipse. 18x^2+36y^=648
Thepotemich [5.8K]
Hi,

18x^2+36y^2=648\\&#10;&#10;\Rightarrow ( \dfrac{x}{6})^2+( \dfrac{y}{3* \sqrt{2} } )^2=1\\&#10;&#10;a=6,\ b=3* \sqrt{2}\\&#10;&#10;c= \sqrt{a^2-b^2} = \sqrt{36-18} =3* \sqrt{2}\\&#10;&#10;
Center is (0,0)
Foci are (-3√2,0) and (3√2,0)
