Hi Dez123,

Graph the system of equations. {−x+2y=−8 3x−y=−6

−y= −3x + 8

6x − 2y = 8

Multiply y = 3x − 8 by -1

y = 3x − 8

6x − 2y = 8

y = 3x − 8

−2y = −6x + 8

y = 3x − 8

y = 3x − 4

The graph is in the picture below!

Hope This Helps!

Course Activity: Relationships Betwee

Alenkinab [10]

Answer:

yes

Step-by-step explanation:

A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.

Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.

Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number

The volume of a sphere is 288pi cm^3 What is the radius of the sphere?

Otrada [13]

Answer:

radius = 6 cm

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = $\frac{4}{3}$ πr³ ← r is the radius

Given V = 288π, then

$\frac{4}{3}$ πr³ = 288π

Multiply both sides by 3 to clear the fraction

4πr³ = 864π ( divide both sides by 4π )

r³ = 216 ( take the cube root of both sides )

r = $\sqrt[3]{216}$ = 6

Thus the radius of the sphere is 6 cm

A population is normally distributed with mean 18 and standard deviation 1.7. (a) Find the intervals representing one, two, and

elena55 [62]

Answer:

Interval within 1 standard deviation: (16.3,19.7)

Interval within 2 standard deviation: (14.6, 21.4)

Interval within 3 standard deviation: (12.9, 23.1)

Step-by-step explanation:

We are given the following in the question:

Population mean, $\mu$ = 18

Standard deviation, $\sigma$ = 1.7

We have to find the following intervals:

Interval within 1 standard deviation:

$\mu \pm 1\sigma\\=18 \pm 1.7\\=(16.3, 19.7)$

Interval within 2 standard deviation:

$\mu \pm 2\sigma\\=18 \pm 2(1.7)\\= 18 \pm 3.4\\=(14.6,21.4)$

Interval within 3 standard deviation:

$\mu \pm 3\sigma\\=18 \pm 2(1.7)\\= 18 \pm 5.1\\=(12.9,23.1)$
