Answer:
i think c
Step-by-step explanation:
I think he lost $375 because I'm pretty sure your supposed to multiply 55 and 7
It does represent a direct variation.
Direct variation: y = kx
y varies directly with x
Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2 + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2
Yes. That point is in the solution space.
_____
You can also figure out algebraically whether the point satisfies the inequality
y < 2x + 10
Substitute the numbers
3 < 2·2 + 10
3 < 14 . . . . . . . . . . . True. (2, 3) is a solution
Step-by-step explanation:
|3x - 4| = 6
3x-4 = 6 or 3x-4 = -6
3x=6+4 3x=-6+4
3x=10 3x = -2
x= 10/3 x = -2/3
so, x1= 10/3 or x2 = -2/3
