Does the system have one solution, no solution, or infinite
solutions?
8x - 4y = 12
y = 2x - 3

Answers

Answer 1

Answer: infinite solutions

Step-by-step explanation:

If you check on desmos and plugged in both equations on there, you would see that the lines are placed exactly the same/have the same points, making it infinite solutions :)

Step-by-step explanation:

suppose 7,500 is invested at 1.5%, compounded continuously. what will the account balance be in 16 years?​

Answers

Answer:

[tex]\boxed {\boxed {\sf \$9,534.37}}[/tex]

Step-by-step explanation:

The formula for continuously compounded is:

[tex]A=Pe^{rt}[/tex]

where P is the principal amount, r is the interest rate as a decimal, and t is the amount of time.

The principal amount is $7,500 and time is 16 years. The interest rate is 1.5%. Convert this to a decimal- divide by 100 or move the decimal places two spots to the left.

1.5/100= 0.015         or           1.5 --> 0.15 --> 0.015

Now we know all the values and can substitute them into the formula.

[tex]P= 7500 \\r= 0.015 \\t= 16[/tex]

[tex]A= 7500(e^{0.015*16})[/tex]

Solve the multiplication in the exponent first.

[tex]A= 7500(e^{24})[/tex]

Solve the exponent.

[tex]A= 7500 (1.27124915)[/tex]

[tex]A=9534.368627[/tex]

Round to the nearest cent (hundredth place). The 8 in the thousandth place tells us to the round the 6 to a 7.

[tex]A=9534.37[/tex]

The account balance will be $9,534.37 after 16 years.

Please help will give Brain to you!!

Answers

Answer:

A

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then each coordinate of the original point is multiplied by the scale factor 2, that is

D(- 4, 6 ) → D'(2(- 4), 2(6) ) → D'(- 8, 12 )

E(4, 2 ) → E'(2(4), 2(2) ) → E'(8, 4 )

F(- 2, - 2 ) → F'(2(- 2), 2(- 2) ) → F'(- 4, - 4 )

Thus the image coordinates are

D'(- 8, 12 ), E'(8, 4 ), F'(- 4, - 4 ) → A
