Answer:
p(x - 4) = x³ - 12x² + 48x - 69
Step-by-step explanation:
To evaluate p(x - 4), substitute a = x - 4 into p(a), that is
p(x - 4) = (x - 4)³ - 5
= (x - 4)(x - 4)(x - 4) - 5 ← expand 2nd/ 3rd factors using FOIL
= (x - 4)(x² - 8x + 16) - 5 ← distribute parenthesis
= x³ - 8x² + 16x - 4x² + 32x - 64 - 5 ← collect like terms
= x³ - 12x² + 48x - 69
You convert inches into centimeters
2.54*1.5=3.81
The answer to this question is 3.81

<span>Given -1 as based
number, we need to look for another number to be able to produce a positive
answer.
First, remember always the rule in multiplying any negative number to another
negative number will produce a positive answer.
Let’s have an example:
=> -1 x - 2
=> + 2
though we have 2 negative numbers multiply, the answer is positive.
Mathematics rule:
Positive x Positive = Positive
Positive x Negative = Negative
negative x negative = Positive.</span>
Answer:
Step-by-step explanation:
<u>Given lines:</u>
- - 6x + 3y = -9 and
- y + 1 = -3(x + 2)
To determine the answer we need to compare slopes of the lines.
Parallel lines have same slopes, perpendicular lines have negative-reciprocal slopes.
<u>Let's put them in slope-intercept form:</u>
- - 6x + 3y = -9 ⇒ -2x + y = - 3 ⇒ y = 2x - 3
- y + 1 = -3(x + 2) ⇒ y + 1 = -3x - 6 ⇒ y = -3x - 7
As we see the slopes are 2 and -3, so the lines are neither parallel nor perpendicular
