Answer:
see explanation
Step-by-step explanation:
The y- intercept is at (0, 6) ⇒ c = 6
The x- coordinate of the vertex is at the midpoint of the zeros, that is
m = 
= 
= - 2
Since the zeros are x = - 3 and x = - 1 then the factors are (x + 3), (x + 1) and
f(x) = a(x + 3)(x + 1) = a(x² + 4x + 3)
Comparing with f(x) = ax² + 8x + 6 ⇒ a = 2
Thus
f(x) = 2x² + 8x + 6
Substitute m = - 2 into the equation for value of n
n = 2(- 2)² + 8(- 2) + 6 = 8 - 16 + 6 = - 2
Hence
c = 6, m = - 2, a = 2, n = - 2
So yeah the correct answer is y. I hope this is what u needed.
Answer:
x = 24°
Step-by-step explanation:
What do the sum of all angles in a triangle add up to?
- The sum of all angles in a triangle add up to 180°.
First, let's find the missing angle of the big triangle (the angle next to 111°).
- 94 + 41 = 135
- 180 - 135 = 45°
Now, we can find the value of x given the smaller triangle's angle.
- x + 111 + 45 = 180
- x + 156 = 180
- x = 24
Therefore, x = 24°.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer: x=25, y=19
Step-by-step explanation: Because the triangle is equilateral, all the angles must be equal to 60 degrees. So 2x+10=60. 2x=50 and x=25. Then the same thing: 3y+3=60. 3y=57, y=19.
I wish i knew the answer to your question but i don't But you should download photomath in the app store it will help you out with your math it gives you the answer and the work to it
