Nat2105 [25]
Let x be the amount invested at 7% and y the amount invested at 6%

We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500 
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500

Find the x-intercepts for the parabola defined
Ulleksa [173]

Answer:

(- 2, 0 ), (1, 0 )

Step-by-step explanation:

Given

y = 2x² + 2x - 4

To find the x- intercepts let y = 0, that is

2x² + 2x - 4 = 0 ← divide through by 2

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Thus x- intercepts are (- 2, 0) and (1, 0)
