Answer:
f(x) = (-1/2)(x^2 + 8x - 15)
Step-by-step explanation:
This function has two roots: -3 and 5. Most likely it is a quadratic (all of which have two roots).
Then f(x) = a(x + 3)(x - 5)
The graph goes through (1. 8): Therefore, y = 8 when x = 1:
f(1) = a(1 + 3)(1 - 5) = 8, or
a(4)(-4) = 8, or
-16a = 8, which leads to a = -1/2.
Thus the quadratic in question is f(x) = (-1/2)(x + 3)(x - 5), or
f(x) = (-1/2)(x^2 + 8x - 15)
Answer:
56°
Step-by-step explanation:
2x+3x+5=90
5x=90-5
5x=85
x=85÷5
x=17
m<2=3x+5=3(17)+5=51+5=56
Answer:
34 degrees
Step-by-step explanation:
ok so 180-111=69
then the opposite angle from 37 is also 37
the the missing angle from the left triangle has to be 103
so then the angle below x is 77
and so we know x = 34 degrees
I hope that made sense.
Answer: I think its B or C bc if you subtract them on the 180 you will get the same answer and by just adding them back again.
Step-by-step explanation:
The answer should be 74% probability
35/50+5/50-3/50= 37/50->74%
