Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
6x + 10y = 8 ( subtract 6x from both sides )
10y = - 6x + 8 ( divide each term by 10 )
y = -
x +
= -
x 6 +
← in slope- intercept form
with slope m = -
→ C
1.70 - 0.45 = 1.25
1500 ÷ 1.25 = 1200

To solve this equation, lets move all of the variables to one side of the equation and the constants to the other.
0.12x - 1.5 = 0.24x - 0.06
Subtract 0.12x from both sides of the equation
-1.5 = 0.12x - 0.06
Add 0.06 to both sides of the equation
-1.44 = 0.12x
Divide both sides by 0.12 to isolate x
x = -12
It depends on what level of classes you take, but algebra classes in college do tend to be harder than algebra classes in high school or middle school.
