26.) 3(2)² - 8(-3)²

= 3*4 - 8 + 9

= 12 - 8 + 9 = 13

27.) I 7 - 4(2) I

7 - 8 = -1, but  since this is absolute value, which is a number's distance from zero, your answer for 27 would be a positive one.

28.) (-2)² + 2(-3 * 1)

= 4 + 2(-3)

= 4 + (-6) = 4 - 6 = -2

29.) 7(-4)² + 5 / 4(1) - (-5)

=7 * 16 + 5 / 4 + 5

= 112 + 5 / 9 = 117/9 = 13

30.) Product: the result of a multiplication problem

Increased by: multiplied by

Find the x-intercept and the y-intercept of the graph of the equation.
andriy [413]

Answer:

<em>x</em><em> </em><em>=</em><em> </em><em>6</em>

Step-by-step explanation:

<em>To</em><em> </em><em>attain the</em><em> </em><em>x-intercepts</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>to</em><em> </em><em>let</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>0</em><em>.</em>

<em>So</em><em> </em><em>in</em><em> </em><em>this</em><em> </em><em>case you will be</em><em> </em><em>having</em><em>:</em>

<em>4</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>(</em><em>0</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em>

<em>4</em><em>x</em><em>/</em><em>4</em><em> </em><em>=</em><em> </em><em>2</em><em>4</em><em>/</em><em>4</em>

<em>x</em><em> </em><em>=</em><em> </em><em>6</em>

<em>Hopefully</em><em> </em><em>it</em><em> </em><em>makes sense</em><em>.</em>
