Answer:A

Step-by-step explanation:

Think about it as a process of elimination.

It can't be "B' for the simple fact that "increased by'' is a term that is often used for addition problems.

It can't be "C" because, as previously stated, sum is a term that is used in addition problems.

It can't be "D" because this is a unit that you are using.

The graph of y = 4 – is shown.

Rather than try to select the correct answer without doing work, I'd rather do the work first and the matching later.

Given y = 4 - x, or y = 4 - 1x,

1) the y-intercept is (0,4).
2) this being a linear function, it has neither maximum nor minimum.
3) the x-intercept is found by letting y = 0 and solving for x: 0 = 4 - x; x - 4. The x-intercept is (4,0).

Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can

Answer:

The house is 18.75 feet tall

Step-by-step explanation:

The triangles are similar by the AA postulate.

We are given the length of the bottom sides of the triangles, 4 and 15 respectively.

Thus, the ratio is 4:15

We are also given the height of Annie's eyes, which is 5 feet. The height of the side that corresponds to the house is 5, so we can set up a proportion.

$\frac{4}{15} = \frac{5}{x} \\4x = (5*15) = 75\\x = \frac{74}{4} \\x = 18.75$
