Answer:
y = 3x - 1
The rate of change of the function is 3.
Step-by-step explanation:
The equation of the linear function through the points (- 2, - 7)and (1,2) will be given by
⇒ (y + 7) = 3(x + 2)
⇒ y = 3x - 1 (Answer)
Now, the rate of change of the function is the slope of the line i.e. 3. (Answer)
We know the equation of a straight line which passes through the points and is given by
Pythagoras theorem.... The thing I hate the most..
In a traingle if you know two if its sides ( we say A and B ) you square them and get the third side C .
You didn't understand.
Let me explain.
We have a triangle, one side is 4cm other is 3cm how do you find the third side?
Yes, Pythagoras theorem.
That is a^2 + b^2 = c^2.
You square 4 and 3:
That will be 16 and 9 then you add them.
16+9= 25 find the root of 25 that is 5.
You get the third side as 5cm.
That's how you use Pythagoras theorem.
Help you with what I don’t see anything
Answer:
x = 2
y = 4
Step-by-step explanation:
y = x + 2
y = 3x - 2
From equation one, y = x + 2
So, substitute x + 2 for y into equation two
We have
x + 2 = 3x - 2
Add 2 to both sides of the equation
x + 2 + 2 = 3x - 2 + 2
x + 4 = 3x
Subtract x from both sides
x - x + 4 = 3x - x
4 = 2x
Divide both sides by by 2
4/2 = 2x/2
2 = x
x = 2
Substitute 2 for x in either of the equations to get y.
Using the first equation, we have
y = 2 + 2
y = 4
