Answer:
-0.8 and -8.2
Step-by-step explanation:
To solve a quadratic you first need to have one side of the equation equal to zero (because x-intercepts are when y is zero).
4x^2 + 24x + 13 = 2x^2 + 6x
2x^2 + 18x + 13 = 0
Then you can use the quadratic formula to solve for x. You will then come to
-18 ± sqrt(220) / 4
This will simplify out (rounding to the nearest tenth) to -0.8 and -8.2

Answer:
k = 4/5
Step-by-step explanation:
5/6 k = 4/3 - 2/3
5/6 k = 2/3
Multiply both sides of the equation by 6,
5k = 2*2
5k = 4
Divide by 5,
k = 4/5
