Answer:
C) 0
Step-by-step explanation:
The opposite of 0 is 0.
X-54
Y- 36
180-126 to find x
And 54+ y= 90
Step-by-step explanation:
linear function
y = ax + b
f(-4) = -4
x = -4
y = -4
-4 = a×-4 + b
f(4) = -1
x = 4
y = -1
-1 = 4a + b
sum both equations
-5 = 0 + 2b
b = -5/2
-1 = 4a - 5/2
3/2 = 4a
a = 3/2 / 4 = 3/8
the function would be
y = 3/8 x - 5/2
Answer:
y=2/3x-4
Step-by-step explanation:
V30% mixture + v100% mixture = v60% mixture
0.3(10-x) + x = 0.6(10)
3 - 0.3x + x = 6
0.7x = 6 - 3
0.7x = 3
x = 3/0.7
x = 4.286 quarts
