3 0

Answer:

0 & 1

Step-by-step explanation:

3(1 + x) < x + 6

Distribute

3x+3 < x+6

Subtract x from each side

3x+3-x < x+6-x

2x+3 <6

Subtract 3 from each side

2x+3-3 <6-3

2x <3

Divide each side by 2

2x/2 <3/2

x <3/2

Serhud [2]

Answer:

P^{-1} (x)=\sqrt{\frac{x-1}{2} }

Step-by-step explanation:

1. P(x)=2x^{2} +1

2. y=2x^{2} +1

3.x=2y^{2} +1

4.2y^{2} =x-1

5.y^{2} =\frac{x-1}{2}

6.y=\sqrt{\frac{x-1}{2} }

7.P^{-1} (x)=\sqrt{\frac{x-1}{2} }

Find the exact value of each expression, if it defined. ( if answer is undefined, enter undefined) tan (-1)
Triss [41]

Answer:

tan(-1) \approx -0.02

Step-by-step explanation:

The given expression is

tan(-1)

The tangent of -1 is defined, it's around -0.02.

The tangent is a trigonometric function with a period of \pi, where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".

However, at x=-1, the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.

tan(-1) \approx -0.02

Which graph represents the circle given by the equation x + y - 4x + 9y -7 = 0?
PSYCHO15rus [73]

The graph of the circle equation is graph (d)

<h3>How to determine the circle?</h3>

The equation is given as:

x^2 + y^2 - 4x + 9y -7 = 0

Rewrite as:

x^2 - 4x + y^2 + 9y = 7

Express (x^2 - 4x) and (y^2 + 9y) as perfect squares.

So, we have:

(x - 2)^2 + (y + 3)^2 = 7 + 4 +  20.25

Evaluate the sum

(x - 2)^2 + (y + 3)^2 = 31.25

A circle equation is represented as:

(x - h)^2 + (y - k)^2 = r^2

Where

Center = (h, k)

Radius = r

So, we have:

(h, k) = (2, -3)

r^2 = 31.25

r = 5.5

The circle that has a center of (2, -3) and a radius of 5.5 is graph d

Hence, the graph of the circle equation is graph (d)
