Answer:
10°
Step-by-step explanation:
the sum of interior angles of triangle is 180°
so. 8x+x+90°=180°
9x=90°
x=10°
I’m in 11th. I feel stupid
Answer:
well, the cheap answer is
f(x) = -3| x - 1 | is really just f(x) = -3| x - 1 | + 0.
now, what value of "x" makes the absolute value expression to 0?
well, let's just set it to 0 and check,
x - 1 = 0
x = 1
so if "x" ever becomes 1, the | x - 1| will turn to 0, therefore, the vertex is at
f(x) = -3| (1) - 1 | + 0 --------------> ( 1, 0 )
Answer:
Step-by-step explanation:
B
C

E
The y-int. is found by setting x = 0: 3(0) + 2y = 7, or 2y = 7, or y = 7/2.
So the y-intercept is (0,7/2). You could also write "b=7/2."
