Answer:

-x^2-2x-3

Step-by-step explanation:

  • Question 1: Just substitute in the values of f(x) and g(x) and simplify!

  1. f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
  2. f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
  3. f(x)-g(x) = -x^2-2x-3

Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)

Hope this helps!!

Suppose y varies directly with x, and y = 24 when x = 8. What is the value of y when x = 10?
Solnce55 [7]
First, you want to set up a proportion.

8/24 = 10/y

Cross multiply to get

240 = 8y, then divide 8 from both sides to get y = 30.

Answers for the 2 boxes please :)​
scoray [572]

Answer:

(8, - 5 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 4 → (1)

- x - 3y = 7 → (2)

Multiplying (2) by 3 and adding to (1) will eliminate the x- term.

- 3x - 9y = 21 → (3)

Add (1) and (3) term by term to eliminate x, that is

0 - 5y = 25

- 5y = 25 ( divide both sides by - 5 )

y = - 5

Substitute y = - 5 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(- 5) = 4

3x - 20 = 4 ( add 20 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

solution is (8, - 5 )
