The formula of the circumference of a circle is:

C = 2 * π * r

Since r is not given, I will use all choices to find the radius. Whatever circumference corresponds to the correct radius of the problem, then it is the correct one.

a) 22.0 cm = 2 * 3.14 * r ⇒ r = 22.0 cm / 6.28 ⇒ r =   3.50 cm
b) 69.1 cm = 2 * 3.14 * r ⇒ r = 69.1 cm / 6.28 ⇒ r = 11.00 cm
c) 34.5 cm = 2 * 3.14 * r ⇒ r = 34.5 cm / 6.28 ⇒ r =   5.49 cm
d) 17.3 cm = 2 * 3.14 * r ⇒ r = 17.3 cm / 6.28 ⇒ r =   2.75 cm

The value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.

<h3>What is a number line?</h3>

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

The value of x that will satisfy this condition can be found by simplifying the given inequality. Therefore, The given inequality can be simplified as,

4x + 1 - 1 ≥ -8

4x ≥ -8

x ≥ -2

Hence, the value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞ of the number line will satisfy this condition.

dimaraw [331]

Answer:

There intersecting lines

Step-by-step explanation:

5x+2y=-8

-5x            -5x

2y=-8 -5x

/2   /2  /2

y=-4 -5/2x also

y=-5/2x - 4

&

y=5/2x - 19

neither parallel (slope is not the same)

or perpendicular (slope is not reciprocal or opposite signed)

hope i helped
