Answer:
solid...(-3,0)(-4,-1)...shaded below the line
slope = (-1-0) / (-4-(-3) = -1/(-4 + 3) = -1/-1 = 1
y = mx + b
-1 = 1(-4) + b
-1 = -4 + b
-1 + 4 = b
3 = b
this line is : y < = x + 3 <== (thats less then or equal)
====================
solid...(1,1)(2,-1)...shaded below the line
slope = (-1-1) / (2-1) = -2/1 = -2
y = mx + b
1 = -2(1) + b
1 = -2 + b
1 + 2 = b
3 = b
Step-by-step explanation:
So time = distance/speed
515/216 = 2.38 min
in mixed number , 2 whole 83/216 !
Substitute what you know y is equal to into the equation:
y = x + 2
3/2x - 2 = x + 2
Then you can simplify your equation by multiplying both sides by 2 to eliminate the fraction which will give you:
3x - 4 = 2x + 4
Add the -4 to the other side to get 8 and subtract the 2x from the 3x so you have:
x = 8 Now solve for y by substituting your value for x into the other equation:
y = 3/2(8) - 2 Simplify by combining your numbers and you get:
y = 10 Check your answer by substituting y and x into the original equation:
(10) = (8) - 2
Correctly done! So your answers are x = 8 and y = 10
Answer:
yes because the hours to distance is moving at a constant rate and if you were to graph it, it would also go through the origin
Step-by-step explanation:
Answer:
Julie's bill came to $121 for the month in which she ordered 12 movies.
Step-by-step explanation:
Let x represent the number of movies ordered.
Julie: $70 + ($4.25/movie)x, and ...
Tim: $49.50 + ($5.50/movie)x
If Julie ordered 12 movies last month, then her bill came to
$70 + ($4.25/movie)(12 movies) = $70 + $51 = $121
Please be clearer about what you want here. Are you refering to Julie or to Tim or to both when you write, "an equation that best represents the amount of movies?"
