Solving Linear Equations
((22)3) = 25
False
((22)3) =26
The slope of a vertical line is undefined.
True
the slope of the line 2y = 4x + 2 is 4.
False: we must first rewrite the equation in slope-intercept form by solving for y:
2y = 4x + 2 (divide by 2)
y = 2x + 1
So the slope is 2.
The equations 6x + 5y = 300 and 3x + 7y = 285 represent the money collected from selling gift baskets in a school fundraising event. If x represents the cost for each snack gift basket and y represents the cost for each chocolate gift basket, what is the cost for each chocolate gift basket?
What is y = 30
the following equation:
4(x - 4) = 5x - 12 - x
has no solution
True
4(x - 4) = 5x - 12 - x
4x - 16 = 4x - 12
-16 = -12
No Solution
x/2 + x/3 = x - 7
x = 42
|x2 + 1| = x2 + 1
True
