which equation in point slope form correctly represents zadas pay in dollars, y, when she works x hours?

Firlakuza [10]

ANSWER

The correct answer is A

$y-68=2(x-4)$

<u>EXPLANATION</u>

We were told that Zada is paid at an hourly rate of $ $12$ per hour.

The unit rate of payment represents the slope of the straight line graph that models Zada's earnings. Thus $m=12$

When she works for 4 hours she earns a total of $68 tells us that the point, $(4,68)$ lies on the model straight line.

Using the formula for the point slope form

$y-y_1=m(x-x_1)$

we obtain the equation as follows.

$y-68=2(x-4)$

Please Answer the question and show your work, Thx

Answer: 126cm, 136.5cm, 147cm, 144cm, 100cm

Step-by-step explanation: 5% increase is the same as multiplying by 1.05, and to do it in reverse you divide instead.

120*1.05=126cm

130*1.05=136.5cm

140*1.05=147cm

151.2/1.05=144cm

105/1.05=100cm

A. Comparing the statement here, since Ansel Adam's is a master photographer, he is an artist.

B. Ansel Adams is an artist, but it is possible that not all artists are master photographer.

A is the correct option.

1. All master photographers are artists.

Please show me step by step how to solve 6/13 =3/c ?

motikmotik

6/13 = 3/c
You need to cross multiply to solve this.
That means you need to multiply the numerator on the left by the denominator on the right and the denominator on the left by the numerator on the right.

6c = 39
c = 6.5

To check it, input the number you got into the c in the equation.

6/13 = 3/6.5
0.46 = 0.46

Question 6 (Essay Worth 2 points)<br> Find all polar coordinates of point P = (2, 14°).

andrey2020 [161]

Answer:

(2,14°+360n) and (-2,14°+(2n+1)180°)

Step-by-step explanation:

You start out with (2, 14°)

The polar coordinate can be written as (r, 0) = (r, 0+2nπ) or

(r,0)=(-r,0+2(n=1)π), where n is any integer.

The polar coordinates point : p=(r,0) = (2,14°)

For the positive value of r, the polar coordinate can be written as

p=(2,14°) = (2,14°+360n°), where n is any integer.

For the negative value of r , the polar coordinate can be written as

p=(2,14°) = (-2,14°+(2n+1)180°), where n is any integer.

All the polar coordinates of point P are(2,14°+360n) and (-2,14°+(2n+1)180°).
