Let's solve your equation step-by-step.
−3x2−4x−4=0
Step 1: Use quadratic formula with a=-3, b=-4, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−4)±√(−4)2−4(−3)(−4)
2(−3)
x=
4±√−32
−6
Answer:
No real solutions.
The number in parenthesis after f is the x coordinate. Basically, it says which y coordinate is tied with an x value. In choice a, it says that when x is 0 y is 3, etc.
So, you can look at the graph to see which answer choice has a point from the graph. Choice a says (0,3), and that does not match. Choice b says (5,-1) and that does match. So the answer is B.
*(x,y)*
Answer:
1/2
Step-by-step explanation:
(y2-y1)/(x2-x1) is the equation for finding slope with two given points
-5-(-2) over 3-9 equals
-3/-6=-1/-2=1/2
21
Step-by-step explanation:
pemdas 4+3=7 then multiply 7×2=14 then add 14 to 21 ehich equals 21
