Find the amount of time. 8. I = $2000, P = $5000, r = 8%

algol [13]

Answer:

t = 5 years

Step-by-step explanation:

I = $ 2000

P = $ 5000

r = 8%

$I = P * \frac{r}{100}*t\\\\t =\frac{ I * 100}{P*r}\\\\t =\frac{2000*100}{5000*8}\\\\ = 5$

Midpoint (10,4) Endpoint (9,-4), find the coordinates of the other endpoint.

mestny [16]

Answer:

(11, 12)

Step-by-step explanation:

Mid point coordinates:

x = (x₁ + x₂)/2
y = (y₁ + y₂)/2

Since midpoint and one endpoint given (10, 4) and (9, -4), the other endpoint:

x₂ = 2x - x₁ = 2*10 - 9 = 11
y₂ = 2y - y₁ = 2*4 - (-4) = 12

So the other endpoint is: (11, 12)

How do you solve the system: y+1=2x 5y+5=10x

Marta_Voda [28]

Answer:

choose "infinitely more solutions"

Step-by-step explanation:

Let's solve this system by substitution method

y+1=2x

- 1 = - 1

y = 2x -1 <-- sbstitute this in the next equation

---------------------------------------------------------------------------------

5y+5 = 10x

5(2x -1) + 5 = 10x

10x -5 + 5 = 10x

10x + 0= 10x

- 10x = -10x

0 = 0 <-- infinitely more solutions

Free_Kalibri [48]

Answer:

6x²y(9 - 2y)

Step-by-step explanation:

Step 1: Factor out GCF

6(9x²y - 2x²y²)

Step 2: Factor out x²

6x²(9y - 2y²)

Step 3: Factor out y

6x²y(9 - 2y)

And we have our factored answer.
