Answer:
y = 2x² + 16x + 11
Step-by-step explanation:
first foil (x + 4)² to get x² + 8x + 16
distribute 2 to get 2x² + 16x + 32
subtract 21 from 32
Answer:
Step-by-step explanation:
Slope = 2 and passes point (4,7)
The equation is y - y1 = m(x - x1)
And y1 = 7 while x1 = 4, m = 2
: - y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 8 + 7
y = 2x - 1 this is the equation
Answer:
$ 5.98
Step-by-step explanation:
20/100 × 22.42/1 = $ 4.48
$ 22.42 - $ 4.48 = $ 17.94
If they split that bill in two each would pay $ 5.98
I hope this helps.
