Answer:

The following expressions become negative:

1) x+y = 1+(-2) = -1

3) x times y = xy = (1)(-2) = -2

4) x divided by y = x/y = 1/-2 = -2

Step-by-step explanation:

Given

x = 1

y = -2

Computing by substituting x = 1, and y = -2

1) x+y = 1+(-2) = -1

2) x - y = 1 - (-2) = 1+2 = 3

3) x times y = xy = (1)(-2) = -2

4) x divided by y = x/y = 1/-2 = -2

It is clear from the above calculations that when we put x = 1, and y=-2 then the expressions (x+y), (x times y), and (x divided by y) become negative.

Therefore, the following expressions become negative:

1) x+y = 1+(-2) = -1

3) x times y = xy = (1)(-2) = -2

4) x divided by y = x/y = 1/-2 = -2

Use the graph below to answer the following question:

larisa [96]

ANSWER

B) -1

EXPLANATION

From the graph,

f(1)=3 and f(4)=0.

The average rate of change from x=1 to x=4 of this function is,

$= \frac{f(4) - f(1)}{4 - 1}$

Substitute the functional values

$= \frac{0 - 3}{3}$

Simplify

$= \frac{-3}{3} = -1$

The correct choice is .

Darya [45]

Answer:

I dont know But maybe the answer is No

Step-by-step explanation:

0.3 is 30% and if 1/10 is 10% then 2/20 must be 10% because 5% is 1/20

so maybe 3/20 is only 15%

I hope this helps :)

Triangle X Y Z is shown. Angle Y X Z is a right angle. The length of Y X is 12 inches and the length of X Z is 10 inches. Angle

mario62 [17]

The best approximation for the measure of angle XYZ is 39.8° ⇒ 2nd answer

Step-by-step explanation:

Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle

The trigonometry ratios of the angle BAC, the opposite side to this angle is BC and the adjacent side to it is AB are
