Step-by-step explanation:

a=20⁰ vertically opposite angles are equal

b=160⁰ sum of angles on a straight line add up to 180⁰

(180⁰-20⁰=60⁰)

c=125⁰ sum of angles on a straight line add up to 180⁰

(180⁰-35⁰-20⁰=125⁰)

When graphing 5x-3y>30 do we shade above or below?

Hatshy [7]

Answer:

below

Step-by-step explanation:

5x - 3y > 30

-3y > -5x + 30 divide by negative switches the inequality

y < 5/3x - 10 y is less than 5/3x - 10 so shade below the line

Which expression corresponds to this graph?

Elodia [21]

Answer: Choice A

The number line graph is visually showing every number that is 19 or smaller; hence $x \le 19$

Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.

A rational expression is undefined whenever its numerator is zero.

kipiarov [429]

Answer:

False

Step-by-step explanation:

for a rational number expressed as (A / B) where A & B are integers

if the numerator (A) is zero, then (A/B) is simplify zero

i.e (A / B) = (0 / B) = 0

however if the denominator (B) is zero, then by definition any value divided by zero is undefined.

(A / B) = (A / 0) = {undefined}

If p and q are distinct primes. Find the number of positive divisors of<br> p^2 * q^2

kkurt [141]

Answer:

Step-by-step explanation:

We know that for $p^mq^n$ where p and q are different prime numbers the number of positive divisors are (m+1) (n+!)

We have given $p^2q^2$

So here m=2 and n=2

So number of positive divisors $=(2+1)\times (2+1)$ =9

So the number of positive divisors of $p^2q^2$ is 9
