Answer:
-23x^3+20x^4+25x^2+84x-84
Step-by-step explanation:
1 Expand by distributing sum groups.
4x^2(3x+5x^2-6)-7x(3x+5x^2-6)+14(3x+5x^2-6)
2 Expand by distributing terms.
12x^3+20x^4-24x^2-7x(3x+5x^2-6)+14(3x+5x^2-6)
3 Expand by distributing terms.
12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+14(3x+5x^2-6)
4 Expand by distributing terms.
12x^3+20x^4-24x^2-(21x^2+35x^3-42x)+42x+70x^2-84
5 Remove parentheses.
12x^3+20x^4-24x^2-21x^2-35x^3+42x+42x+70x^2-84
6 Collect like terms.
(12x^3-35x^3)+20x^4+(-24x^2-21x^2+70x^2)+(42x+42x)-84
7 Simplify.
-23x^3+20x^4+25x^2+84x-84
Answer:
p = 8
Step-by-step explanation:
Given that,
42p = 414
We need to find the value of p. It can be done by dividing both sides by 42. So,
Out of the given options, option (b) i.e. 8 is the nearest option. So, the value of p = 8.
Answer:
m < 3
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
One added to the quotient of m and 3 is less than 2
(m/3) + 1 < 2
<u>Step 2: Subtract 1 from both sides</u>
(m/3) + 1 - 1 < 2 - 1
(m/3) < 1
<u>Step 3: Multiply both sides by 3</u>
(m/3) * 3 < 1 * 3
<em>m < 3</em>
<em />
Answer: m < 3
Answer:
See below in bold.
Step-by-step explanation:
a. The y coordinate will be (0, 25,350) as $25,350 is the value of the new car at year 0.
The x coordinate will be when the car is worth zero dollars and this is at the point (13, 0).
b. The slope = -25,350 / 13 = -1950.
c. The equation is y = -1950x + 25350.
d. To draw the graph just join the above 2 points.
