Answer:
y = 3x² - 6x - 72
Step-by-step explanation:
Since the roots are x = - 4 and x = 6 then the factors are
(x + 4) and (x - 6) and the quadratic function is
y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so
y = 3(x + 4)(x - 6) ← expand factors and distribute by 3
y = 3(x² - 2x - 24)
y = 3x² - 6x - 72
Answer:
One piece of pizza = $2.5
One candy bar = $1
Step-by-step explanation:
Call 1 pizza a, 1 candy bar b. We have:
2a + 3b = $8
=> 3(2a+3b) = 3. $8
= 6a + 9b = $24
and
6a + 5b = $20
=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4
=> b = $1
=> 2a + $3 = $8
=> 2a = $5
=> a = $2.5
So one piece of pizza = $2.5, one candy bar = $1
