Answer:
solutions at -1 and 11
Step-by-step explanation:
(-b ± √b²-4ac) / 2a
in this problem, a = 1, b = -10, c = -11
(10±√100-4(-1)(-11)) / 2(1) =
(10 + √144) / 2 = 22/2 = 11
(10 - √144) / 2 = -2 / 2 = -1
Answer:
y=8/5x-11
Step-by-step explanation:
Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
