A.) The rate of change is the ratio of y changing to x. In other words, it's the slope of the line

b.) This can also be found based on the slope. If the slope is positive, y increases as x increases. If it is negative, y decreases as x increases. If the slope is 0, y is neither increasing nor decreasing because it is a horizontal line. Hint: it may be helpful to graph the line so you can see what's going on

c.) The y-intercept is where the line crosses the y-axis. This can be found by plugging in x=0 into the equation. For number 11, the y-intercept is 0.

d.) This can be found by plugging in any number for either variable and then solving for the other. For number 11, if you plug in x=10, you get y=15, so you get the point (10,15)

If you have 49 questions on a test what score must you get to pass the test?

Well, on every test I have at a school and I believe most schools do this. You need at leasr 80% to pass. But to pass you'd most likely need 80% or 70%. But if you get an 80% you'll be sure to pass! I hope this helps you!

Kelly uses cruise control to drive at a constant speed. She travels first 192 miles in 3 hours. At the rate, how long will it ta

ioda

Answer:

Step-by-step explanation:

rate = d / t

rate = 192 / 3

rate = 64 miles / hour

Now you want to know how long it can take to get 448 miles

d = r * t

t = d / r

t = 448/64

t = 7 hours.

You could actually do it using proportions.

192/3 = 448/x Cross multiply

192*x = 448*3

192*x = 1344 Divide by 192

x = 1344/192

x = 7

Do this the way you feel is the best way.

need help with this problem drop down1: 6, 10drop down2: 6, 10drop down3: less than (<), greater than (>), less than or eq

Kryger [21]

From the information given,

x represents number of small boxes while y represents number of large boxes.

If each small box can hold 6 books and each large box can hold 10 books, it means that the expression for the number of books that x small boxes and y large boxes can hold is

6x + 10y

If James can pack up to 110 books, it means that the number of books that he can pack is less than or equal to 110. The inequality representing this scenario is

6x + 10y ≤ 110

10y ≤ - 6x + 110

Dividing both sides of the equation by 10, we have

y ≤ - 6x/10 + 110/10

y ≤ - 3x/5 + 11

The graph is shown below

The inequality that represents this sitaution is 6x + 10y ≤ 110

The graph of the inequality wil have solid boundary at y = - 3x/5 + 11

and will be shaded below the line.
