Answer:
x = 420/11
Step-by-step explanation:
Answer:
Step-by-step explanation:
60% of 220 is 132. So thats the sale. The tax is 7% of that. So 7% of 132 is 9.24 So 132+9.24=141.24
we know that
If two lines are parallel, then their slopes are the same
m1=m2
and the y-intercept is unequal
If two lines are perpendicular, then the product of their slopes is equal to -1
m1*m2=-1 or m1=-1/m2
therefore
<u>the answer is</u>
Two non vertical lines have slopes m1 and m2, respectively. The lines are parallel if m1=m2 and the y-intercept are unequal; the lines are perpendicular if m1*m2=-1 or m1=-1/m2.
The answer is 2.94 because you divide 6.174 over 2.1
