PLEASE HELP!<br> solve for x and then find measure for angle b

Bezzdna [24]

<h3>Answers:</h3><h3>x = 12</h3><h3>Angle B = 45 degrees</h3>

===========================================================

Explanation:

Angles A and B are alternate exterior angles.

Due to the parallel lines, alternate exterior angles are congruent

A = B

5x-15 = 2x+21

5x-2x = 21+15

3x = 36

x = 36/3

x = 12

Use this x value to find the measure of angle B

angle B = 2x+21

angle B = 2*12+21

angle B = 24+21

angle B = 45 degrees

As a check,

angle A = 5x-15

angle A = 5*12+15

angle A = 60-15

angle A = 45 degrees

Since A and B are both 45 degrees, this confirms the correct x value

The intercepts are the points where the graph crosses the x or y-axis

<em>The x-intercepts changed from 0 to </em> $\±\sqrt 3$ <em>.</em>
<em>The y-intercepts changed from 0 to 3</em>

The functions are given as:

$f(x) = x^2$

$g(x) = x^2 - 3$

<u>Function f(x)</u>

$f(x) = x^2$

The x-intercept is calculated as follows:

Set f(x) to 0

$x^2 = 0$

Solve for x

$x = 0$

The y-intercept is calculated as follows:

Set x to 0

$f(0) = 0^2$

$f(0) = 0$

Hence, the intercepts are 0

<u>Function g(x)</u>

$g(x) = x^2 - 3$

The x-intercept is calculated as follows:

Set g(x) to 0

$x^2 - 3 = 0$

Solve for x

$x^2 = 3$

$x = \±\sqrt 3$

The y-intercept is calculated as follows:

Set x to 0

$g(x) = x^2 - 3$

$g(0) = 0^2 - 3$

$g(0) = - 3$

The x-intercepts are $\±\sqrt 3$ , while the y-intercept is -3

By comparing the intercepts of f(x) and g(x),

<em>The x-intercepts changed from 0 to </em> $\±\sqrt 3$ <em>.</em>
<em>The y-intercepts changed from 0 to 3</em>
