You might have made an error the first time you solved for x. I got x = -0.5.

When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:

2x + 3 = 4^(1/2) ... Simplify

2x + 3 = 2

2x = -1

x = -1/2

If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?

What is the answer to 4(y-1)-1=2(2y-3)

Ostrovityanka [42]

4(y - 1) - 1 = 2(2y - 3)
4(y) - 4(1) - 1 = 2(2y) - 2(3)
4y - 4 - 1 = 4y - 6
4y - 5 = 4y - 6
- 4y - 4y
-5 ≠ -6

I know it’s not -2 please help!!

Answer:

$\boxed { - 4}$

Step-by-step explanation:

Substitute y = x-4 in the first equation.

$3x - 2(x - 4) = 4$

Distribute -2 in the expression.

$3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x = - 4$

Because we only want to find the value of x.

Therefore the answer is -4.

In the textile industry, a manufacturer is interested in the number of blemishes or flaws occurring in each 100 feet of material

klemol [59]

Answer:

The probability that can be applied to the given situation is Poisson distribution

Step-by-step explanation:

The probability that can be applied to the given situation is Poisson distribution because this distribution applied when the duration of occurrence of an event is known. In the given question laws have occurred every 100 feet therefore we have the number of events that have occurred. Moreover, Poisson distribution predicts the probability of events in fixed time interval
