G(x) is the same as saying y =

y = (2)⁻¹ When an exponent is negative it is the same as the inverse of it

y = 1/2¹

y = 1/2

Find the zeros of y = x2 – 6x – 4 by completing the square.

katrin [286]

Answer:

The solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

Step-by-step explanation:

Given the function

$y\:=\:x^2\:-\:6x\:-\:4$

substitute y = 0 in the equation to determine the zeros

$0\:=\:x^2\:-\:6x\:-\:4$

Switch sides

$x^2-6x-4=0$

Add 4 to both sides

$x^2-6x-4+4=0+4$

Simplify

$x^2-6x=4$

Rewrite in the form (x+a)² = b

But, in order to rewrite in the form x²+2ax+a²

Solve for 'a'

2ax = -6x

a = -3

so add a² = (-3)² to both sides

$x^2-6x+\left(-3\right)^2=4+\left(-3\right)^2$

$x^2-6x+\left(-3\right)^2=13$

Apply perfect square formula: (a-b)² = a²-2ab+b²

$\left(x-3\right)^2=13$

$\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}$

solve

$x-3=\sqrt{13}$

Add 3 to both sides

$x-3+3=\sqrt{13}+3$

Simplify

$x=\sqrt{13}+3$

now solving

$x-3=-\sqrt{13}$

Add 3 to both sides

$x-3+3=-\sqrt{13}+3$

Simplify

$x=-\sqrt{13}+3$

Thus, the solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

By what number should I multiply 1 1/4 by to obtain 3/4(fractions)

Reptile [31]

1 1/4x = 3/4
5/4x = 3/4
x = (3/4) / (5/4)
x = 3/4 * 4/5
x = 12/20 which reduces to 3/5

check..
1 1/4 * 3/5 =
5/4 * 3/5 =
15/20 reduces to 3/4

so u would multiply 1 1/4 by 3/5 to get 3/4

1. A shirt is on sale for 45% off. The original

sleet_krkn [62]

Answer:

$13.75 , $11.25

Step-by-step explanation:

If they took off 45% of the original price, that means you gotta subtract

$25 - 45% = 13.75

to find the amount of the discount, subtract 13.75 from 25

$25-$13.75 = $11.25
