Lines are parallel if and only if there slopes are the same
the slope will be m in the equation y=mx+b notice that the coefficient of y is 1
a)y=3/5x+1
b)5y=3x-2---> divide the whole equation by 5-->y=3/5-(2/5)
c)10x-6y=-4-->solving for y--->-6y=-4-10x--->dividing by -6--->y=(-10/-6)x-(4/-6)
so a and b are parallel
for the second question
a)4x-3y=2---->-3y=2-4x---->y=(2/-3)+(4/3)x
b)3x+4y=-1--->4y=-1-3x---->y=(-1/4)-(3/4)x
c)4y-3x=20--->4y=20+3x--->y=5+(3/4)x
so no parallel lines in the second question

Step-by-step explanation:
Answer:
H0 : u = 8500
H1 : u > 8500
Step-by-step explanation:
Given:
sample size, n = 350
mean, u = 8500
Sample mean, x' = 8745
Standard deviation = 1,200
Level of significance = 0.05
In this case, the financial administrator believes that the average cost of tution, room and board at small liberal arts colleges is higher than the reported $8500. We can say this is the alternative hypoyhesis, since it is a claim.
The null hypothesis would be the opposite of the alternative hypothesis.
Therefore, the null and alternative hypotheses are:
H0 : u = 8500
H1 : u > 8500
Answer:
x = 5
Step-by-step explanation:
Given:
a = x
b = 12
c = 13
Work:
a² + b² = c²
x² + 12² = 13²
x² + 144 = 169
x² = 25
x = 5
Answer:
option <em><u>c</u></em><em><u> </u></em>
