Minutes(m) Cost
0 20
10 22
20 24
50 30
slope formula:
m = (y1 - y2) / (x1 - x2)
m = (20 - 22) / (0 - 10) = -2/-10 = 1/5 or 0.20
y = (1/5)(x) + 20
The rule that describes Amy's monthly cost is:
m = 1/5x + 20 or m = 0.20x + 20
Where x is the number of minutes spent on the call.
4 - 8 = -4
A negative number is alwats at the left in a horizontal line.
Let's try to rapresent it.
-4 -3 -2 -1 0 +1 +2 +3 +4
So, you count from +4 to -4
Your answer is "8 units to the left of 4"
#11 and #12 have no solutions, #13 has a solution which is 14
Answer:
23 degrees
Step-by-step explanation:
So basically you plug in -10x + 58 = 111 and then solve for x. You then plug x into 6x +41. Thats how you find the angle measure. Plz award brainliest
Guessing you meant by a factor of 3... not 13 since none of the solutions are anywhere close to that.
to compress is to smoosh.
It's the equation of a line. If you smoosh it vertically the line becomes flatter and the slope smaller.
Essentially g(x) = 3f(x)
3y = 12x + 6
y = (12/3)x + 6/3
y = 4x + 2
