A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10

Answers

Answer 1
Answer: B is the correct answer
Answer 2
Answer:

Answer:

B. y=-9x-10

Step-by-step explanation:

The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.

1/4 h + 9 = 3/4 h - 7

Answers

remember you can do anything to an equation as long as you do it to both sides

try to get the unknown by itself
we hates fractions
times everybody by 4
h+36=3h-28
minus h both sides
36=2h-28
add 28 both sides
64=2h
divide both sides by 2
32=h
1/4 h - 3/4h = -7 -9
-1/2 h = -16
h = 32

An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length of the lake. What are the dimensions of the lake?

Answers

The area is width times length, so you'd divide the area by the width. This is 9/20 divided by 1/5. When dividing fractions, you flip the second number then divide straight across. This would be 9/20 x 5/1. You'd get 45/20, or in mixed number form, 2 and 1/4.

Students in a class were asked to name their favorite sport they like to watch on television. How many more time students want to watch basketball over students who want to watch soccer? Basketball 25.5%Soccer .03%

Answers

First, we need to add up all the percentages to make sure we have 100%.

25.5% + 0.03% = 25.53%

This means that 74.47% of the students chose something other than basketball or soccer.

The amount of students you stated there were was 2553.

25.5% of 2553 is 651 students and

0.03% is 8 students.

Now, we divide 651 by 8 to determine the amount of times over basketball was chosen.

651 ÷ 8 = 81

Basketball was chosen 81 times over again compared to soccer.

 To find how much more times basketball was chosen, subtract 8 from 651

651 - 8 = 643

Basketball was chosen 643 times more than soccer.
