He starts with 10, +5 after every week
week 2=10+5
week 3=10+5*2
...
week 25 =10+5*24
f(x)=10+5(x-1)
so during the 25th week=10+5*24=10+120=130

Two six sided dice are rolled. What is the probability of the total being less than or equal to 4?

The ways to get a total of four or less with two fair dices are:

(1,1)

(1,2)

(1,3)

(2,1)

(2,2)

(3,1)

out of 36 possible outcomes, so the probability is

P(<=4) = 6/36 = 1/6

What is the y-value that goes with an x-value of 5?
Dennis_Churaev [7]

Answer: y = 7- 5x

Step-by Step Explanation: The variable x is multiplied by a larger value here; it's multiplied by 5. So I should expect that my y-values will grow fairly quickly. This means that I should expect a fairly "tall" graph.

First I'll do the T-chart.

T-chart

This equation is an example of a situation in which you will probably want to be particular about the x-values you pick. Because the x is multiplied by a relatively large value, the y-values grow quickly. For instance, you probably wouldn't want to use x = 10 or x = –7 as inputs. You could pick larger x-values if you wished, but your graph would very quickly get awfully tall.

I can see, from my T-chart, that my y-values are getting pretty big on either end (that is, in the positive numbers above the horizontal axis, and in the negative numbers below). I don't want to waste time computing points that will only serve to make my graph ridiculously large, so I'll quit with what I've got so far. But I'm glad I plotted more than just two points, because lines that start edging close to vertical can easily go wrong, if I'm not neat in my work.

Here's my graph:

y = 7 - 5x

Can somebody help me with this math question, all you have to do is answer the equation, then it's described, and then it draw i
natali 33 [55]

Answer:

X= - 2

Step-by-step explanation:

-3 (5x+6) - 3x = 6-6x

Remove the parentheses

-15x-18-3x=6-6x

Collect the like terms

-18x-18=6-6x

Move the variable to the left-hand side and change its sign

18x+6x=6+18

Collect the like terms

-12x=24

Divide both sides

X=-2
