What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method​
Artyom0805 [142]

Answer: Equation form: x=-2,y=-1

Point form: (-2, -1)

Step-by-step explanation:

y=-\frac{3x}{2} -4

y=-2x-5

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Solve by Substitution ---> 2x+y=-5 3x+2y=-8

Investment of $2000 at 10% simple interest for 9 years
Oliga [24]

Answer:

The last investment (C) has the least interest of $600

The other two investments (A and B) have the <u>same</u> amount of interest of $1800.

Step-by-step explanation:

<u>Simple Interest Formula</u>

I = Prt

where:

  • I = interest earned
  • P = principal
  • r = interest rate (in decimal form)
  • t = time (in years)

<u>Investment A</u>

  • P = $2000
  • r = 10% = 0.1
  • t = 9 years

Substitute the given values into the formula and solve for I:

⇒ I = 2000(0.1)(9)

⇒ I = $1800

<u>Investment B</u>

  • P = $3000
  • r = 3% = 0.03
  • t = 20 years

Substitute the given values into the formula and solve for I:

⇒ I = 3000(0.03)(20)

⇒ I = $1800

<u>Investment C</u>

  • P = $2000
  • r = 10% = 0.1
  • t = 3 years

Substitute the given values into the formula and solve for I:

⇒ I = 2000(0.1)(3)

⇒ I = $600

The last investment (C) has the least interest of $600.

The other two investments (A and B) have the <u>same</u> amount of interest of $1800.

Did ancient mathematicians use a ruler to determine the values of sine and cosine in a circle?

They didn’t use a ruler I think they made their own materials from what they had. Also thank you.
