PLEASE HELP Write The Equation Of The Line In Slope-intercept Form.The Equation Of The Line In Slope-intercept

Answers

Answer 1

Answer:

y = 50x + 20

Step-by-step explanation:

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Use the slope-intercept formula to find the slope.

[tex]m = \frac{120 - 20}{2 - 0}[/tex]

[tex]m = \frac{100}{2} = 50[/tex]

The y-intercept is where the line crosses the y-axis.

Answer 2

Answer:

y = 50x + 20

Step-by-step explanation:

finding slope or gradient, choose any two points on the line i.e (2.0, 120) and (0.0, 20)

m = (y2 - y1)/(x2 -x1)

= (120-20)/(2.0-0.0)

= 100/2

= 50

finding the equation of the line using point (0,20)

=> y = mx + c

=> 20 = 50*0 + c

=> c = 20

so equation of the line

=> y = 50x + 20

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:

Your first bungee jump is 50 1/6 feet higher than your second jump. Your first jump reaches −200 2/5 feet. Select the equation you can use to find the height h (in feet) of your second jump. Then find the height of your second jump.

Answers

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

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).

alice average mark for 4 science exams is 68%. Can alice score enough marks In a fifth exam so that her average Mark increases to 75% give reasons

Answers

Answer:

it is impossible she gets a 75% because as far as we know she can only score a maximum of 100 and she needs a 103

Step-by-step explanation:

We're going to assume that alice got a 68 on all 4 of her science exams

which means that so far we have[tex]\frac{68+68+68+68}{4}=68[/tex]

And we need to find out if she can get a 75 which means that we have the following

[tex]\frac{68+68+68+68+x}{5}=75[/tex]

Solve for x

272+x=375

x= 103

Therefore (unless there is extra credit available in the exam) it is impossible she gets a 75% because as far as we know she can only score a maximum of 100

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.
