Explain how two angles can be complementary angles.

1 answer:

4 0

Two angles can be complementary angles add up to 90. So if you have a angle that is 30 and another one that is 60 those would be complementary because if you add them up they add up to 90.

What is the slope of the line going through (-2,-3) and (-4,-9)

aleksklad [387]

3/1 or just 3

Slope is the change in y over the change in x.
Y2-Y1/X2-X1

-9 - (-3) / -4 - (-2)

-6/-2 = 3

Two quantities are related, as shown in the table:

Rashid [163]

Answer:

$y = \frac{1}{2} x + 2$ .

Step-by-step explanation:

From the given table it is clear that x and y are linearly related.

Now, any two points that satisfy the relation between x and y are sufficient to express the equation.

The first two given points are (2,3), and (4,4).

Therefore, the equation is $\frac{y - 4}{4 - 3} = \frac{x - 4}{4 - 2}$

⇒ $y - 4 = \frac{1}{2} (x - 4)$

⇒ $y - 4 = \frac{1}{2} x - 2$

⇒ $y = \frac{1}{2} x + 2$ . (Answer)

Use slopes and y-intercepts to determine if the lines -5x – 4y = -3 and -5x – 5y = -3 are parallel

Bogdan [553]

Answer:

Not parallel.

Step-by-step explanation:

If the slopes are the same they are parallel.

So we convert each one to slope-intercept form:

-5x - 4y = -3

-4y = 5x - 3 Divide both sides by -4:

y = -5/4 x + 3/4.

Slope = -5/4.

-5x – 5y = -3

-5y = 5x - 3 Divide both sides by -5:

y = -1 x + 3/5.

Slope = -1.

The slope are different - so NOT parallel.
