Answer:

the desired equation is y = – 4x + 3

Step-by-step explanation:

Parallel lines have the same slope and thus similar equations. Thus, the equation of a line parallel to the given line has the form y = – 4x + C. We need only find C.

The new line goes through (2, -5), and so we substitute 2 for x and -5 for y to obtain

-5 = – 4(2) + C. Then -5 + 8 = C, or C = 3.

Then the desired equation is y = – 4x + 3

Two sides of a triangle measure 27 inches and 32 inches. Which could represent the length of the third side?

charle [14.2K]

Answer:

Step-by-step explanation:

The third side could have dimension x

32 - 27 < x < 32 + 27

5 < x < 59

There are a few special triangles

Equilateral triangle could have legs

27, 32, 27

32, 27, 32

A right triangle could have the third side

√(27² + 32²) = √1753 which is about 41.87

√(32² - 27²) = √295 which is about 17.18

Notice all these fit within the original limits specified.

coldgirl [10]

The relationship between the number of tickets is that Hannah sold three times as many tickets as Andrea.

<h3>How to determine the relationship?</h3>

From the question, we have:

Andrea = h

Hannah = 3h

This means that:

Hannah = 3 * Andrea

So, the relationship is that Hannah sold three times as many tickets as Andrea.
