What’s the answer to this

Mathematics
1 answer:
grigory [225]2 years ago

Answer:

A.  x = -5/6  and  x = 1/2.

Step-by-step explanation:

12x^2 + 4x - 5 = 0

Use the 'ac' method to try to factor this:

Consider the above highlighted numbers:

12 * -5 = -60.

Now we need 2 numbers whose product is -60 and whose sum is +4.

They are -6 and +10, so we replace the + 4x by -6x + 10x:

12x^2 - 6x + 10x - 5 = 0   Now factor by grouping:

6x(2x - 2) + 5(2x - 1) = 0   The 2x -1 is common, so:

(6x + 5)(2x - 1) = 0

So x = -5/6  and  x = 1/2.

Maddox wants to go back to college full-time. His current employer has agreed to reduce his hours from 40 hours to 25 hours whil
4vir4ik [10]

Answer:

Best fit for his new situation is modified budget A

Step-by-step explanation:

lets first calculate Wages which will be earned by Maddox after reduction of working hours .

from his current situation we can say that ,

for working of 40 hours ,  Maddox monthly income wages = $1760

so  for working of 1 hour , Maddox monthly income wages = $1760÷40=$44

hence for working of 25 hour , Maddox monthly income wages will be $44 × 25 = $1100.

So New wages after reduction of working hours will be $1100. but if you see , in budget B and C , Income wages is considered as $1600 which will not be case after reduction of working hours to 25 . hence Maddox cannot go for Modified Budget B and Modified Budget C.

So he needs to decide between Modified Budget A and Modified Budget D.

Now lets concentrate upon Net income for Modified Budget A and Modified Budget D. Net income for Modified Budget D is in negative that is -$515. that means he need to earn $515 more to meet Budget D , but income wages are fixed that is $1100.

At last lets see Net income of modified budget A. he is able to save $30 , hence we can say that best fit for his new situation is modified budget A
