Ramona has a new job as a chef. She earns the same
DaniilM [7]

Answer:

y = 10x  + 100

Step-by-step explanation:

Given the information:

She earns the same  amount per hour as she did in her old job $ 100 sign-on bonus

=> the equation for line p in the form y= mx  where:

  • x is the number of hour she worked
  • y the money she earned

=>  the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus )

From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q

We can create two points (0, 0) and (2, 20) are on line p  

<=> m = \frac{y2-y1}{x2-x1} = \frac{20-0}{2-0} = 10

The equation for line p is y = 10x

=>The equation for line q should include the hourly earnings at the

new job plus the sign-on bonus. The equation is y = 10x  + 100

Hope it will find you well.

PLEASEEEEEEEEEEEEEEEEEEEEEE Edgar rolls two six-sided number cubes. What is the probability that he rolls a 2 on
sleet_krkn [62]
<h3>Answer:  Choice C</h3>

4/36 = 1/9

==============================================================

Explanation:

Circle the second row. This is where each of the red die results are "2"

Then look at the cases when the second die is less than "5". So we could have a 1, 2, 3, or 4 on this second die.

As you can see, there are 4 cases when the first number is a 2 (red) and the second number is less than 5 (white).

We have m = 4 cases we want out of n = 6*6 = 36 cases total.

m/n = 4/36 = 1/9 is our final answer.
