Answer:

See explanations below

Step-by-step explanation:

Given the quadratic formula that expresses the temperature of a chemical reaction

C(t)=-12t² +8t +93

Given that C(t) = 110°, we are to find the value of t

Substitute

110 = -12t² +8t +93

-12t² +8t +93-110 = 0

-12t² +8t -17 = 0

12t² -8t + 17 = 0

Using the general formula;

t = -(-8)±√(-8)²-4(12)(17)/2(12)

t = 8±√64-816/24

t = 8±√-752/24

<em>Since the value of t will give a complex number, hence the time doesn't exist when the reaction reaches 110°C</em>

Solve |2x - 1| + 3 = 6.
umka21 [38]

Answer:

x =2                         x = -1

Step-by-step explanation:

|2x - 1| + 3 = 6.

Subtract 3 from each side

|2x - 1| + 3-3 = 6-3

|2x - 1|= 3

An absolute value has two solutions, one positive and one negative

2x-1 =3                   2x -1 = -3

Add 1 to all sides

2x-1+1 =3+1             2x-1+1 = -3+1

2x = 4                      2x =-2

Divide by 2

2x/2 = 4/2                 2x/2 = -2/2

x =2                         x = -1
