3x + -1y = 12
Solving
3x + -1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
3x + -1y + y = 12 + y
Combine like terms: -1y + y = 0
3x + 0 = 12 + y
3x = 12 + y
Divide each side by '3'.
x = 4 + 0.3333333333y
Simplifying
x = 4 + 0.3333333333y</span>
Answer:
(B)
Step-by-step explanation:
Because if 20 times out of 30 he got under 6,
60 would be double as 30 so that would mean it would be double the chance so its 40.
To get y - intercept put the value of x =0
so 4y = -3
y= -3/4
The answer is the letter c and d
Answer:
Equation of the perpendicular line is
Step-by-step explanation:
Given equation is y = 5x - 4
By comparing this equation with slope-intercept form of the equation,
y = mx + b
Slope of this line
Let the slope of the perpendicular line =
By the property of perpendicular lines,
Equation of the perpendicular line passing through a point and slope m is represented by
If the given point is (10, -1) and slope 'm'=
