$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Circumference of circle is :

$\qquad \tt \dashrightarrow \:\pi d$

where,

d = diameter of circle

$\qquad \sf \dashrightarrow \:c = 20 \pi \: \: cm$

Now, let's plug approximate value of pi

$\qquad \sf \dashrightarrow \:c = 20 \times 3.14\: \:$

$\qquad \sf \dashrightarrow \:c = 62.8 \: \: cm$

What is the slope of (8,10), (-7,14)

Murrr4er [49]

Reduce the expression, if possible, by cancelling the common factors.

Exact Form:
−4/15

Decimal Form:
−0.26

Basically do
y2-y1 divided by x2-x1
14-10 divided by -7-8
which equals -4/15

Which ordered pairs are solutions to the inequality y - 3x < -8?

7nadin3 [17]

Answer:

Option B,C and E are solution to given inequality $y - 3x < -8$

Step-by-step explanation:

We need to check which ordered pairs from given options satisfy the inequality $y - 3x < -8$

Ordered pairs are solutions to inequality if they satisfy the inequality

Checking each options by pitting values of x and y in given inequality

A ) (1, -5)

$-5-3(1)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

B) (-3, - 2)

$-2-3(-3) < -8\\-2-9$

So, this ordered pair is solution of inequality as it satisfies the inequality.

C) (0, -9)

$-9-3(0)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

D) (2, -1)

$-1-3(2)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

E) (5, 4)

$4-3(5)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

So, Option B,C and E are solution to given inequality $y - 3x < -8$
