A submarine is 4,000 feet below sea level, and rising a rate of 100 feet pre minute. Write an equation to represent y, the depth of the submarine after x minutes.
Answers
Answer:
y = 100x - 4000Step-by-step explanation:
Initial elevation is a starting point, therefore y-intercept is -4000The rate of change is the slope, therefore m = 100The equation of the linear function is:
y = 100x - 4000Explanation: the submarine is 4000 feet BELOW sea level which is why in the equation there is a negative sign. Then the submarine rises 100 feet per minute and the x represents minutes and y is the depth of the submarine.

Mira has breakfast at a restaurant she leaves a 20% tip of $1.80 what is the price of breakfast before the tip
Answers
♡ Answer ♡
$9
♡ Step-by-step explanation ♡
In the problem, it states that Mira leaves a $1.80 tip. At the same time, it is also mentioned that the tip is 20% of the price of breakfast before it. This means that $1.80 is 20% of the price of breakfast before the tip. In order to figure out the price of breakfast before the tip, we must take the 20% tip and make it into 100%. This 100% will be equivalent to the price of breakfast (before the tip).
To transform 20% into 100%, we must multiply by 5. Therefore, to find the price of breakfast before the tip, we must multiply $1.80 by 5. When we do this, we discover that $1.80*5 is $9. $9 is 100% of the price of breakfast before the tip.
So, the price of breakfast before the tip is $9.

What is the inverse of the statement?
A number that has exactly two distinct factors is prime.
If a number has exactly two distinct factors, then the number is prime.
If a number does not have exactly two distinct factors, then the number is not prime.
If a number is not prime, then the number does not have exactly two distinct factors.
If a number is prime, then the number has exactly two distinct factors.
Answers
The inverse statement of "if number that has exactly two distinct factors is prime" is that B. If a number that does not has exactly two distinct factors is not prime"
How to illustrate the information?Each of the original statements is presupposed to be false in an inverse statement. "If it is not snowing" would be the polar opposite of "If it is snowing." "Then it is not chilly" would be the polar opposite of "then it is cold."
In this case, the inverse statement of "if number that has exactly two distinct factors is prime" is that B. If a number that does not has exactly two distinct factors is not prime.
Therefore, based on the information, the correct option is B.

The 2) commutative property states that A plus B equals B plus A.
What is the commutative property?The commutative property of addition or multiplication implies that changing the order of numbers for the addition or multiplication operation cannot change the result.
Reordering the addends does not change the outcome of the addition of multiplication operations.

What is the value of g(f(x)) ? Ο Α. . -6 OB. C. 19 D. 31
Answers
Answer:
D. 31
Step-by-step explanation:
Given:
[tex] f(x) = 4x^3 - 10 [/tex]
[tex] g(x) = \frac{3x - 4}{2} [/tex]
Required:
The value of g(f(2))
First, find f(2).
Substitute x = 2 into [tex] f(x) = 4x^3 - 10 [/tex].
[tex] f(2) = 4(2)^3 - 10 [/tex]
[tex] f(2) = 4*8 - 10 = 32 - 10 [/tex]
[tex] f(2) = 22 [/tex]
Next, find g(f(2)).
[tex] g(f(x)) = \frac{3(22) - 4}{2} [/tex]
[tex] g(f(x)) = \frac{66 - 4}{2} [/tex]
[tex] g(f(x)) = \frac{62}{2} [/tex]
[tex] g(f(x)) = \frac{62}{2} [/tex]

Find the measures of two complementary angles if the difference in their measures is 16.
Answers
Answer:
One of the angles is 53 degrees and the other is 37 degrees.
Step-by-step explanation:
Let x be equal to the measure of the first angle.
Let y be equal to the measure of the second angle.
Because x and y are complementary, they add up to 90 degrees.
x+y=90
The question tells us that x and y have a difference of 16.
x-y=16
Now that we have our two equations, we can use the method of elimination to find the value of x (process is in the picture attached). We do this by adding the two equations since y will cancel out.
x=53
Finally, we can plug x back into either of the original equations to find the value of y.
x+y=90
53+y=90
Subtract both sides by 53 to isolate y
53+y-53=90-53
y=37

What the slope of the line on the graph please help me
Answers
Answer: y=-3/7x+3
Step-by-step explanation:
I gave you the intercept form of slope as well, although you did not ask for it.
Your line angled downwards (reading it left to right) meaning that your slope is negative. Your slope also goes down by 3 and to the right by 7, which is where your 'rise over run' is acquired from.
Rise over run (slope), when positive, is either up/right or down/left
Rise over run (slope), when negative, is either down/right or up/left
Hope this helps.
