PLS I NEED HELP BRAINLIEST IS UP FOR GRABS
Gwar [14]

Answer:

(a) x > 4   (b) y < -2

Step-by-step explanation:

Domain is referring to the x-values while the range is referring to the y-values.

Since the function (the line) has a circle at the point (4, -2), the function will be exclusive at that coordinate.

The line goes to infinity for the x-values from 4, so you write x > 4 or ∞ > x > 4.

Similarly, the line goes to infinity for the y-values from -2, so you write y < -2 or -∞ < y < -2.

How do I factor 8x^2+12+48?
wolverine [178]
<h3><u>4(2x^2 + 3x + 12)</u></h3>

We can factor a 4 out of this expression.

4(2x^2 + 3x + 12)

Now that the expression is simplified, we can see if splitting the middle term is possible.

<em><u>Display factors of 24.</u></em>

1 * 24

-1 * - 24

2 * 12

-2 * -12

3 * 8

-3 * - 8

4 * 6

-4 * -6

All factors of 24 have been listed, and none of these digits satisfy the criteria.

Trinomial cannot be further factored.

Triangle WXY is isosceles. ∠YWX and ∠YXW are the base angles. YZ bisects ∠WYX. m∠XYZ = (15x)°. m∠YXZ = (2x + 5)°. What is the me
DiKsa [7]

Answer:

Option D is correct.

The measure of \angleWYX = 150^{\circ}

Step-by-step explanation:

\triangle WXY is isosceles  and \angle YWX and \angle YXW are base angles.

Isosceles Triangle:

A triangle with two equal sides, and two congruent base angles that means the angles are equal

By the definition, the base angles are equal i.e, m\angle YWX=m\angle YXW

Since, YZ bisects m\angle WYX

Angle Bisector theorem: An angle bisector is a line or ray that divides an angle into two equal angles

then, \angle WYX =2\angle XYZ or

Substitute the value of \angle XYZ=(15x)^{\circ} ;

\angle WYX =2(15x)^{\circ} = (30x)^{\circ}

The sum of measures of these three angles of  triangle WXY is equal to the 180 degree.

In triangle WXY we have;

\angle YXW+\angle WYX+\angle YWX=180^{\circ}

Substitute the value of m\angle YWX=m\angle YXW=(2x+5)^{\circ} and \angle WYX=(30x)^{\circ} in above formula:

2\angle YXW+30x=180^{\circ} or

2\cdot(2x+5)+30x=180^{\circ}

Simplify:

4x+10+30x=180^{\circ}

Combine like terms ;

34x+10^{\circ}=180^{\circ} or

34x=170^{\circ}

Simplify;

x= \frac{170}{34} =5^{\circ}

Substitute the value of x in  \angle WYX;

\angleWYX = (30x)^{\circ} = 30 \cdot 5 = 150^{\circ}

Therefore, the measure of \angleWYX = 150^{\circ}

A differentiable function f has the property that f(x + y) = f(x) + f(y) 1 − f(x)f(y) holds for all x, y in the domain of f. It
Fantom [35]

Answer:

f'(x) = 5[1 + f²(x)]

Step-by-step explanation:

By definition, f'(x) = lim h => 0 {[f(x + h) - f(x)]/h}

This was used, together with the given limits:

lim x => 0 f(x) = 0

lim x => 0 f(x)/x = 5,

to determine the derivative of the given function:

f(x + y) = [f(x) + f(y)]/[1 - f(x)f(y)].

The workings are shown in the attachments.
