The answer is -5/3
Answer:
Values for alpha and beta are 0.5 and 3.
Step-by-step explanation:
2x² - 7x - 3 = 0
2x² - 7x - 3 = (2x - 1 )(x - 3)
∴ (2x - 1 )(x - 3) = 0
The only way to get zero by multiplying two values together, is if one of those values is qual to zero. Therefore, either (2x - 1 )=0, or (x - 3)=0.
If (2x - 1 )=0
∴2x=1
∴x=0.5
If (x - 3)=0
∴x=3
We have two values for x. These values represent alpha and beta.
<em>(BTW - I'm not sure from the phrasing of your question whether or not you just want to find the values or whether you want to find the sum of the values (I don't know if you used '+' to mean 'and' or 'plus'), but if you do want to find the sum, it's of course just 0.5+3= 3.5.)</em>
x equals 4 and y equals 5 . so the formula would be 5x+12y=80 and if we need 4 of the small boxes we sub x for 4 and we get 5(4) =20. Next, 80 minus 20 is 60, and the equation would now be 12y=60. we now divide both sides by 12 and we get left with y=5. 5x + 12y = 80 5(4) + 12(5)=80 20+60=80. That is all. I hope that doesn't sound confusing
