Re-write the quadratic function below in Standard Form y= –2(x + 5)(x – 4)

Mathematics
1 answer:
Naddik [55]3 years ago
6 0

Answer:

y = - 2x² - 2x + 40

Step-by-step explanation:

Standard form of a quadratic is y = ax² + bx + c : a ≠ 0

Given

y = - 2(x + 5)(x - 4) ← expand factors using FOIL

  = - 2(x² - 4x + 5x - 20)

  = - 2(x² + x - 20) ← distribute parenthesis by - 2

  = - 2x² - 2x + 40 ← in standard form

PLZ HELP ASAP CIRCLES PART 2
Sveta_85 [38]
For this case we have the following angle:
 theta = (9/5) pi
 Having the conversion we have:
 theta = ((9/5) pi) * (180 / pi)
 Rewriting we have:
 theta = (9/5) * (180)
 theta = (9/5) * (180)
 theta = 324 degrees
 Answer:
 
The angle is equivalent to:
 
theta = 324 degrees

Help please................
Zinaida [17]
The answer is yes she incorrectly graphed using the points (-2,4) instead of the point (4,-2). This is the answer because if you solve the equation given you should get y=-3/5x+2/5 so a and e will be wrong and if you plug one of the points in you will give a untrue statement so its not d so you are left with b and c so you plug in the end request and you get a true statement with b equaling -2 if you plug in 4 in for x
