Decay
What are the coefficients
in the expression
3x4 - xy + 2y - 7 ?
3, -1, 2
Solve for w.
-4w + 10 = 34
w=-6
Solve for y.
3y + x = 10
y = 10 - x / 3
5x - 4 ≥ 54
x ≥ 10
Identify the parts of this expression: y = 200 (1.04)x
Initial Value, Growth Factor,
And whether it’s Growth or Decay
Initial Value = 200
Growth Factor = 1.04
Exponential Growth
Simplify the following expression:
3x + 4 - 2(x + 1)
x+2
Solve for x.
2x + 4 - 6 = 3(x - 1)
x = 1
Liam uses lots of data on his phone and has a total of 20 GB available this month, but has already used 14.5 GBs. Write an equation that would help you solve how many GBs Liam could use a week if there are 2.5 weeks left in the month.
x = number of GBs Liam can use each week
2.5x + 14.5 = 20
2(3x - 4) < 4x + 7 - x
x < 5
