To find the intersection points, you take x^2 - 4x + 9 = -2x + 17

This gives x^2 - 2x - 8 = 0,

which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2

From the graph, we can see that x is positive, meaning x = 4, so a = 4.

Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.

a + b = 4 + 9 = 13. The answer is B.

Find two numbers given that their sum is 60 and
likoan [24]

Answer:

12 and 48

Step-by-step explanation:

let n be the larger number , then \frac{1}{4} n is the smaller number and their sum is

x + \frac{1}{4} x = 60 ( multiply through by 4 to clear the fraction )

4x + x = 240 , that is

5x = 240 ( divide both sides by 5 )

x = 48

smaller number = \frac{1}{4} × 48 = 12

The 2 numbers are 12 and 48
