X and Y intercept equations x +2y =18
Rufina [12.5K]

Answer:

(0,9) and (18,0)

Step-by-step explanation:

To find the x-intercept, set y = 0.  Note how this equation x + 2y = 18 becomes x = 18.  Thus, the x-intercept is (18,0).


To find the y-intercept, set x = 0.  Then 2y = 18, and y = 9.  The y-intercept is (0,9).

A card is drawn from a standard deck of 52 cards. What is the theoretical probability as a decimal of drawing the number 8? Roun
Alborosie

The answer would be 0.15 because in a deck there are only 4 cards of 8 (diamonds, hearts, clovers, and spades). Since there are 52 cards, you would divide 8 by 52 to get 0.153846, but since it says to round to the nearest hundredths, the answer would be 0.15.

Can u guys PLEASE answer this question ASAP. THIS IS EXTREMELY URGENT
Ulleksa [173]

Answer:

The answer to your question is $56  

Step-by-step explanation:

Data

Payment before noon = $11.20

Payment after noon = $11.20/2

Time from 9:00 to 16:00

Process

1.- Calculate the hours worked before noon and the hours worked after noon.

    Before noon = 12:00 - 9 = 3 hours

    After noon = 16:00 - 12:00 = 4 hours

2.- Calculate the payment

Payment = (3 x 11.2) + (4 x 11.2/2)

               = 33.6 + 22.4

               = $56
