Write an equation to represent the amount of water in the bucket, y, in terms of the number of minutes, x, since the faucet was turned on

Answers

Answer:

y= 3x+125

Step-by-step explanation:

y intercept is 125

gradient is 3

y=Mx+c

y=3x+125

Answer:

y = 75x + 125

Step-by-step explanation:

Write in form y = mx + b

75 is the slope (m)

125 is the y-intercept (b)

So the equation would be y = 75x + 125.

BTW, the slope is written in rise/run form. For this graph, it is 75/1.

is this statement valid or invalid "if an animal has feathers, than it is a bird. a crow has feathers, so it is a bird"

Answers

Answer:

the statement is valid!

Step-by-step explanation:

first, let's consider the first statement "if an animal has feathers, then it is a bird"

well, let's think about this: are there any animals that have feathers that AREN'T birds? No!

so we know the first statement is true so it is valid

now, let's consider the second statement "a crow has feathers, so it is a bird"

is that true? well based on the first statement, if an animal has feathers it's a bird. so yes! the statement is valid

Answer: The statement is valid.

======================================================

Explanation:

This is valid by the law of detachment. This is also known as "modus ponens".

The basic format is that we have these two premises

If P is true, then Q is trueP is true

Those two premises work together to conclude that Q must be true. Think of it like a set of dominoes. The first domino that you knock over is statement P, which then leads to domino Q being knocked over afterward (ie statement Q must be true because P is true).

Answer:

h= −250 17/30

Step-by-step explanation:

Let's solve your equation step-by-step.

−200 2/5 −50 1/6 = h

Step 1: Simplify both sides of the equation.

−7517/30 = h

Step 2: Flip the equation.

h = −7517/30

Justify each step used to simplify the expression. 1. 3x+ 2y− 2x+ 2 = 3x− 2x+ 2y+ 2

Answers

Step-by-step explanation:

We have to simplify the given expression:

1. 3x+2y-2x+23x+2y−2x+2

Combining the like terms,we get the second step as

2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)

Now, taking 'x' common from the first two terms, we get third step as:

3. (3-2)x+2y+2(3−2)x+2y+2

Now, simplifying the expressions among the like terms, we get fourth step as:

4. x+2y+2x+2y+2
