(5x+2y=23<br> (13x+3y=51

AysviL [449]

Answer:

$[3, 4]$

Step-by-step explanation:

{5x + 2y = 23

{13x + 3y = 51

−5⁄13[13x + 3y = 51]

{5x + 2y = 23

{−5x - 1 2⁄13y = 19 8⁄13 >> New Equation

______________________

11⁄13y = 3 5⁄13

_____ ______

11⁄13 11⁄13

$y = 4$ [Plug this back into both equations above to get the x-coordinate of 3]; $3 = x$

I am joyous to assist you anytime.

Which number line represents the solution set for the inequality 3(8 – 4x) < 6(x – 5)?

diamong [38]

Answer:

A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.

Step-by-step explanation:

We can start by dividing the inequality by 3 to get ...

8 -4x < 2(x -5)

And we can divide by 2 to simplify further to ...

4 -2x < x -5

Now, we can add 2x+5, which gives ...

9 < 3x

and then divide by 3 again:

3 < x

This is graphed on a number line as described above.

For the following amount at the given interest rate compounded continuously, find (a) the future value after 9 years, (b) the

Stella [2.4K]

Answer:

(a) The future value after 9 years is $7142.49.

(b) The effective rate is $r_E=4.759 \:{\%}$ .

(c) The time to reach $13,000 is 21.88 years.

Step-by-step explanation:

The definition of Continuous Compounding is

If a deposit of $P$ dollars is invested at a rate of interest $r$ compounded continuously for $t$ years, the compound amount is

$A=Pe^{rt}$

(a) From the information given

$P=4700$

$r=4.65\%=\frac{4.65}{100} =0.0465$

$t=9 \:years$

Applying the above formula we get that

$A=4700e^{0.0465\cdot 9}\\A=7142.49$

The future value after 9 years is $7142.49.

(b) The effective rate is given by

$r_E=e^r-1$

Therefore,

$r_E=e^{0.0465}-1=0.04759\\r_E=4.759 \:{\%}$

(c) To find the time to reach $13,000, we must solve the equation

$13000=4700e^{0.0465\cdot t}$

$4700e^{0.0465t}=13000\\\\\frac{4700e^{0.0465t}}{4700}=\frac{13000}{4700}\\\\e^{0.0465t}=\frac{130}{47}\\\\\ln \left(e^{0.0465t}\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t\ln \left(e\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t=\ln \left(\frac{130}{47}\right)\\\\t=\frac{\ln \left(\frac{130}{47}\right)}{0.0465}\approx21.88$
