The line y = 8x - 4 intersects the parabola y = x^2 + 2x + 5 at exactly one point. what are the coordinates of the point of intersection?

a. (-3, -28)
b. (-3, 8)
c. (3, 3)
d. (3, 20)

explain how to

D.

Step-by-step explanation:

way №1:

just to substitute the given coordinates into the both equations. Only for answer 'D' will be 20=8*3-4 and 20=3*3+2*3+5.

way №2:

to re-write the right sides as 8x-4=x²+2x+5, then to solve this equation: x²-6x+9=0, where x=3. Then to calculate the value of 'y': y=8*3-4=20. Finally, x=3; y=20, it means (3;20).

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
