20 - 3j
I guess it would be this. Since 20 is the total minus 3(price for the juice) multiplied by the number of bottles of juice. we should get a total of cost charged for, subtract from 20 and get the change amount.
If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)
y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10
y = 5x + 11
Simplify both brackets, this equals 22 + 10x - 17 + 5x
Simplify further and you get 15x + 5
Answer:
-2
Step-by-step explanation:
Start with the vertex form of the equation of a parabola: y - k = a(x - h)^2
Here h = -2, k = -3, x = -1, y = -5. Find a:
-5 - [-3] = a(-1 - [-2])^2, or
-5 + 3 = a(1)^2, or
-2 = a
The unknown coefficient is -2.
Answer:
-0.5, 2, 4.5, 7, 9.5
Step-by-step explanation:
The given terms are 6 apart, so the common difference is 1/6 of their difference:
d = (12 -(-3))/6 = 15/6 = 5/2 = 2.5
Add 2.5 to each term to get the next one. Then the sequence is ...
-3, <u>-0.5</u>, <u>2.0</u>, <u>4.5</u>, <u>7.0</u>, <u>9.5</u>, 12
