Question

#11 please help me solve this

Answer 1

x²+2x-24=0

Explanation:

x=4 or x= - 6

x-4=0 or x+6=0

(x-4)(x+6)=0

x(x+6)-4(x+6)=0

x²+6x-4x-24=0

x²+2x-24=0

Answer 2

y = -3x / 5 - 23 / 5

y = -3x/5 - 4.6

Explanation:

From the graph, we can locate the values of x and y.

When

x1 = -6

y1 = 1

(-6, 1)

When

x2 = 4

y2 = -5

(4, -5)

To get the equation, we First find the find the slope at these points.

Slope (m) = (change in y) / (change in x)

Slope (m) = 1 - (-5) / -6 - 4

= 6 / -10

= 3 / -5

y - y1 = m ( x - x1)

y - 1 = -3/5 ( x + 6)

y - 1 = -3x / 5 - 18 / 5

Add 1 to both sides

y = -3x / 5 - 23 / 5

y = -3x/5 - 4.6
