Whats 2(4k+3)-13=2(18-k)-13 solve

Tju [1.3M]

Answer:

k=3

Step-by-step explanation:

2(4k+3)−13=2(18−k)−13

(2)(4k)+(2)(3)+−13=(2)(18)+(2)(−k)+−13

8k+6+−13=36+−2k+−13

(8k)+(6+−13)=(−2k)+(36+−13)

8k+−7=−2k+23

8k−7=−2k+23

8k−7+2k=−2k+23+2k

10k−7=23

10k−7+7=23+7

10k=30

10k/10=30/10

k=3

Group points {(0,1),(0,5)(2,6),(3,3)}is not a function, but group points {(1,4)(2,7)(3,1)(5,7)} is a function. What do you notic

Tasya [4]

<h2>Any value in the domain of the function should have a unique value in codomain.</h2>

Step-by-step explanation:

In the first set of points $\{$ $\text{(0,1),(0,5)(2,6),(3,3)}$ $\}$ ,

value $0$ maps to two distinct values $1,5$ in the codomain.

This violates the property of functions.

The first set of points does not form a function.

In the second set of points $\{$ $\text{(1,4),(2,7)(3,1),(5,7)}$ $\}$ ,

Every value in domain corresponds to unique value in domain.

There is no violation in the property of functions.

The second set of points does form a function.

Transform the equation x-3y=-15 to express it in slope-intercept form

tiny-mole [99]

X -3y = -15

Subtract 'x' from each side:

-3y = -x - 15

Divide each side by -3 :

<em>y = 1/3 x + 5</em>

This is 'slope-intercept' form.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The z-score is given as

$z = \dfrac{x-\mu }{s}\\$
