<h3>Answer:</h3>

d. The y-intercept is 1 space higher.
a. 9 to the power of -1/2

<h3>Step-by-step explanation:</h3>

1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.

___

2. The rules of exponents apply:

a^b · a^c = a^(b+c)
1/a^b = a^-b

You apparently want to simplify ...

... 9^(1/4) × 9^(1/2) / 9^(5/4)

... = 9^(1/4 + 1/2 - 5/4)

... = 9^((1+2-5)/4)

... = 9^(-2/4) = 9^(-1/2)

3x^3 - 2y^-6x^2y^2+xy for x=2/3 and y=1/2

Dominik [7]

Answer:

-13

Step-by-step explanation:

3x^3 - 2y^-6x^2y^2+xy

x=2/3 and y=1/2

Solve :

3x^3 - 2y^-6x^2y^2+xy

Put value of x and y in this equation

= 3(2/3)^3 - 2(1/2)^-6(2/3)^2(1/2)^2+(2/3)(1/2)

= -13

Given that 2x − 1∶ − 4 = 16x + 1 ∶ 2x − 1 find the possible values of

IRISSAK [1]

The possible values of x are 5 and -1/12

<h3>Complete question</h3>

Given that 2x − 1∶ x − 4 = 16x + 1 ∶ 2x − 1 find the possible values of x

<h3>How to determine the possible values of x?</h3>

The ratio is given as:

2x − 1∶ x − 4 = 16x + 1 ∶ 2x − 1

Express as fraction

$\frac{2x - 1}{x-4} = \frac{16x + 1}{2x -1}$

Cross multiply

4x^2 -4x + 1 = 16x^2 + x -64x - 4

Collect like terms

-16x^2 + 4x^2 + 64x - x - 4x + 1 + 4 = 0

Evaluate the like terms

-12x^2 + 59x + 5 = 0

Divide through by -1

12x^2 - 59x - 5 = 0

Expand

12x^2 + x - 60x - 5 = 0

Factorize

x(12x + 1) - 5(12x + 1) = 0

Factor out 12x + 1

(x - 5)(12x + 1) = 0

Expand

x - 5 = 0 or 12x + 1 = 0

Solve for x

x = 5 or x = -1/12

Hence, the possible values of x are 5 and -1/12
