Rate of change is the same as slope in this case.
(1350-1200)/(2008-2005) = 150/3 = $50 increase per year
The initial amount he started charging was $1200 a year.
y = 50x + 1200, where x represents the number of years since 2005.
Answer:
4 feet tall
Step-by-step explanation:
You can solve this equation by taking 2.5/5 to get 0.5, and then by taking 0.5 times 8 to get 4.
Answer:
X=21.21
Step-by-step explanation:
Cos(45)=15\x
0.707=15\x
15\0.707 =x
X= 21.21
Answer:
Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)
<em><u>answer</u></em><em><u>:</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x³</u></em><em><u>+</u></em><em><u>4</u></em><em><u>x-2x²-8</u></em><em><u>)</u></em>
Part B: Factor the entire expression completely. Show the steps of your work. (6 points)
answer:
<em><u>2y(x³+4x-2x²-8)</u></em>
<em><u>2</u></em><em><u>y</u></em><em><u>(</u></em><em><u>x³-2x²</u></em><em><u>+</u></em><em><u>4</u></em><em><u>x</u></em><em><u>-</u></em><em><u>8</u></em><em><u>)</u></em>
