Answer:
20. Which of the following is the correct first step to solve 5x2 – 20x = -15 by completing the square?
O Divide all terms by 5. this is the answer
O Divide all terms by -5.
Add 15 to both sides.
Add 100 to both sides.
5%
Step-by-step explanation:
First, we already have the perimeter and the sides that we need to find the 5th sides. Next, add all available sides that we have: 5+5+4+4=18. Finally, we need to subtract 27 to 18 to get the final answer is 9 for the 5 the side. Hope you get it.
Answer:
$620
Step-by-step explanation:
20 x 10 = 200 + 420 = 620
hope this helped. :)
p.s. can I get brainliest?
Let the price = P , the years = x , depreciation rate = d<span> and original cost = W
</span>∴
when W = 25,000 , d = %8 = 0.08 and x =7
∴
P = 13,946.165 ≈ 13,946 to the nearest dollar
The price <span>after 7 years = $13,946</span>
Answer:
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
Step-by-step explanation:
First find the slope by choosing two ordered pairs and using the slope formula:
Now use the Point-slope form of linear equation with the found slope and one of the points to create the equation of the linear function:
The rate of change of a linear function is its <u>slope</u>.
Therefore,
B. The equation of the linear function is y = 3x + 2
D. The rate of change of the linear function is 3.
