To do so, get every part into slope-intercept form (y = mx + b).
If the slopes are different, there is one solution.
If the slopes the same but the y intercepts different, there is no solution.
If the slopes and y intercepts are the same, there are infinitely many solutions.
2x + y = 4
2y = 6 - 2x
Solve for y on both
y = 4 - 2x
y = 3 - x
They are both different, so there is one solution
We will find out 7% of 25.
7/100*25
=1.75 %
Therefore, 1.75% of Janie's class has blue eyes.
HARRY POTTER FOREVER! : P
A.) it opens up because it is positive. B. The vertex is a minimum, because it opens up C/ The axis of symmetry is X=-1, the Vertex is (-1,-2). The Y interecept is y= -1
Row A is incorrect, because 3 times 4 is 12 and 12 + 5 = 17 not 20.
