Solve the following equation. 3(2x - 4) = 4(x + 1) x=?
mrs_skeptik [129]

Answer:

x=8

Step-by-step explanation:

3\left(2x-4\right)=4\left(x+1\right)

Expand:

3\times 2x-3\times 4=4x+4\times 1

6x-12=4x+4

Add 12 to both sides:

6x-12+12=4x+4+12

6x=4x+16

Subtract 4x from both sides:

6x-4x=4x+16-4x

2x=16

Divide both sides by 2:

\frac{2x}{2}=\frac{16}{2}

x=8

How much money has to be invested at 2.9% interest compounded continuosly to have 34,000 after 18 years
navik [9.2K]

Answer:

\$20,173.31  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=18\ years\\ A=\$34,000\\ r=0.029  

substitute in the formula above  

34,000=P(e)^{0.029*18}  

P=34,000/((e)^{0.029*18})=\$20,173.31

Given that lim x→a f(x) = 0 lim x→a g(x) = 0 lim x→a h(x) = 1 lim x→a p(x) = [infinity] lim x→a q(x) = [infinity], evaluate the
ANEK [815]

Answer:

Step-by-step explanation:

We have to remind one of the properties of the limits:

Lim x→a  f(x)*g(x) = [Lim x→a f(x)]*[Lim x→a g(x)]

Hence, we evaluate the products of the limits

(a) Lim x→a  f(x)*g(x) = 0*0 = 0

(b) Lim x→a  f(x)*p(x) = 0*[infinity] = INDETERMINATE

(c) Lim x→a  h(x)*p(x) = 1*[infinity] = infinity

(d) Lim x→a  p(x)*q(x) = [infinity]*[infinity] = INDETERMINATE

Answer this in pictures and number of words
qaws [65]

Answer: Tom's solution is incorrect.

Step-by-step explanation:

When you add 3/6 + 1/2 it equals ?.

3 + 1  = ?

6 + 2 = ?

We must have common denominators to do this problem.

So we must have 6 as our common denominator.

So 2 x 3 = 6. But we have to do the same to the Numerator.

So 1 x 3 = 3.

Now our problem is 3/6 + 3/6 = ?

3 + 3 = 6/6. Or 1

1 does not equal 4/12 or 1/3. So it makes it Incorrect.

What you should say:

Tom is incorrect, it is because 3/6 + 1/2 = 1, 1 does not equal 4/12 or 1/3. So, it makes it reasonable for the correct answer to be Incorrect
