Answer:

  (a) a function, but not one-to-one

Step-by-step explanation:

The graph is of a function if it passes the vertical line test: a vertical line intersects the graph in at most 1 point.

The function is one-to-one if it passes the horizontal line test: a horizontal line intersects the graph in at most 1 point.

__

Here, the graph consists of a series of non-overlapping horizontal lines. It passes the vertical line test (is a function), but a horizontal line can intersect the graph in an infinite number of points (is not one-to-one).

The graph is a function, but not one-to-one.

If t=38.5 and s=31.4 find S. Round to the nearest tenth
zubka84 [21]

<u>Answer:</u>

The correct answer option is C. S = 54.6°.

<u>Step-by-step explanation:</u>

We are given a right angled triangle with two known sides, s and t.

We are to find the value of the angle S.

For that, we will use sine.

sin S = \frac { s } { t }

sin S = \frac { 3 1 . 4 } { 3 8 . 5 }

S = sin'0.815

S = 54.6°

How do I use the substitution method to find the point of intersection of
Goshia [24]
To substitute, solve for one variable and then plug it into the other equation you have. In this problem, y is already solved for on the top equation (y=x+2), so you just stuff it into the second equation.

y = x + 2
3y = 4x - 2

3(x + 2) = 4x - 2
3x + 6 = 4x - 2
-x = -8
x = 8
y = x + 2 = 8 + 2 = 10

solution:
x = 8 
y = 10

hope this helps!! :)
