<em>given</em>

y + 2 = - 3/2 ( x + 2 )

<em>distribute</em>

y + 2 = - 3/2x + 3

<em>subtract 2 from both sides</em>

y + 2 = - 3/2x + 3

...

y = - 3/2x + 3 - 2

<em>combine like terms</em>

y = - 3/2x + 1

answer:

y = - 3/2x + 1

the slope is - 3/2

the y intercept is + 1

How do you solve (Arc)QPT if <QZT = 120

yuradex [85]

By definition, the arc length is given by:
arc = R * theta * ((2 * pi) / 360)
Where,
theta: angle in degrees
R: radio
We have then:
(Arc) QPT if <QZT = 120:
theta = 360-120 = 240 degrees
R = 13.5 units
Substituting values we have:
(Arc) QPT = R * theta * ((2 * pi) / 360)
(Arc) QPT = (13.5) * (240) * ((2 * pi) / 360)
(Arc) QPT = 56.55 units
Answer:
(Arc) QPT = 56.55 units

In a experiment, the probability that event A occurs is 5/9, the probability that event B occurs is 5/7, and the probability tha

Ymorist [56]

Answer:

52.5% probability that A occurs given B occurs

Step-by-step explanation:

Suppose we have two events, A and B, the conditional probability formula is:

$P(A|B) = \frac{P(A \cap B)}{P(B)}$

In which

P(A|B) is the probability of A happening given that B happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(B) is the probability of B happening.

In this problem, we have that:

$P(A \cap B) = \frac{3}{8}, P(B) = \frac{5}{7}$

So

$P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{\frac{3}{8}}{\frac{5}{7}} = 0.525$

52.5% probability that A occurs given B occurs

The following table shows the length and width of a rectangle: Length Width Rectangle A 3x 2 2x − 1 Which expression is the resu

Stolb23 [73]

The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.

<h3>What is a perimeter?</h3>

A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.

Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.

$P = 2 (L + W)$

$P = 2 ( 3x+2 + 2x-1)$

$P = 2 ( 5x +1)$

$P =10x +2$

A polynomial function is a function that involves only positive integer exponents of a variable in an equation.

Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
