Answer:
The answer is D.
Step-by-step explanation:
The first thing I did was substitute the variables in for x and y. This is the numbers in the answer choices: (x,y). I don't know if there is an easier way to do this, but you can replace the two numbers in for the variables since it's multiple choice.
For example,
A: -2+2*4=6 Isn't right
B: 1+2*-1= -1 Nope
C: (0,0) you can already tell it's not right because anything multiplied by 0 is 0.
D: -4+2*1=-2 This is the correct answer.
Answer:
y-4 = (-1/3)(x+1)
Step-by-step explanation:
We need to identify the equation in point slope form.
The standard equation of point slope form is:
(y-y₁) = m (x-x₁)
where m is the slope and x₁ and y₁ are the points
We are given point(4,-1) so,
x₁=4 and y₁=-1
And a perpendicular line: y =3x+5
Which is equal to y = mx+b
where m is slope so, slope m = 3
Since the line is perpendicular, so the slope in negative inverse of actual slope that m = -1/m
i.e, m = -1/3
So, the equation in point slope form is:
y-(-1) = (-1/3)(x-4)
=> y+1 = (-1/3)(x-4)
12•6= 72
If you were finding volume then you would multiply it my 8 too, but you need to find area
I'm pretty sure the answer is 6.92 cause when you simplify it you'll get that exact answer
Yes, they are both functions.
