Answer:

Yes, it is a function

Step-by-step explanation:

It is a function because for every y value there is a different x value. We can also use the vertical line test to see if there are two points on the same line.

What is the equation parallel to 3x+2y=8 that goes through the point 2, -4
Gennadij [26K]

Answer:

The equation of the line would be y = -3/2x - 1

Step-by-step explanation:

In order to find this, we first need to find the slope of the original line. We do this by solving for y.

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

Since we know parallel lines have the same slope, we know our new line has a slope of -3/2. We can now use that along with the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -4 = -3/2(x - 2)

y + 4 = -3/2x + 3

y = -3/2x - 1

What is the value of x?
nalin [4]

Answer:

  x = 42.9 m

Step-by-step explanation:

Corresponding sides of similar triangles MAB and MNP are proportional. This means ...

  x/MP = MA/MN

However, we don't have a number for MA yet, so we need to find it.

  MA +AN = MN

  MA = MN - AN            subtract AN

  MA = 67.2 m - 32 m = 35.2 m

Now, we can use this to find x.

  x = MP · (MA/MN) = (81.9 m) · 35.2/67.2

  x = 42.9 m
