If r and p are perpendicular:

1 + 2 = 90°

3 = 90°

4 + 5 = 90°

6 = 90°

If any one of these are true, r and p must be perpendicular

Montano1993 [528]

Step-by-step explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

$\frac{x}{y} * \frac{a}{b }= \frac{x*a}{y*b}$

Addition and subtraction requires that we find a common demoninator.

For example,

$\frac{6}{4} + \frac{4}{3}$

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

$\frac{6}{4}*\frac{3}{3} + \frac{4}{3} \frac{4}{4} = \frac{18}{12}+\frac{16}{12}$

Then we add the numerators

$\frac{18+16}{12} = \frac{32}{12}$

Then we should reduce.

$\frac{16}{6} = \frac{8}{3}$

Division is a little trickier because we have to flip-flop the second term and then multiply. For example: $\frac{1}{10} \div \frac{5}{6} \rightarrow \frac{1}{10} * \frac{6}{5} = \frac{6}{50}$

a line passes through the point (-3,-5) and has a slope of 5 write an equation in point slope form for this line

Tanzania [10]

Answer:

$y=5x+10$

Step-by-step explanation:

1) Plug numbers into slope formula to find $b$ .

$y=mx+b$

$-5=5(-3)+b$

2) Simplify to find $b$ .

$-5=-15+b$

$10=b$

3) Check work.

$-5=-15+10$

This statement is true.

4) Write equation.

$y=5x+10$

Help anyone pleaseeee

AlexFokin [52]

Answer:

36 <127

(36,127°)

36 [ cos (127) + i sin (127)]

Step-by-step explanation:

w1 = 2 < 95

w2 = 18 < 32

w1 * w2

We multiply the magnitude and add the angles

w1 * w2 = 2*18 < (95+32)

=36 < 127

36 [ cos (127) + i sin (127)]
