Answer:
6/7
Step-by-step explanation:
Your first step will be to find the slope of Line C. Using the slope formula of 
, the slope of Line C is 
.
If Line D is perpendicular to C, that means the slope is the negative reciprocal of Line C. So, that means the slope is 6/7.
Answer:
h=7
Step-by-step explanation:
We want to solve the equation:
We multiply through by the LCM: 
Simplify to get:
We expand to get:
h=7
Answer:Total amount of money collected for arena J = $5400
Step-by-step explanation:
Section J in an arena has 20 rows.
Each row has 15 seats. This can also means that section J has 20 rows and 15 columns. The rows and column form a rectanglar shape. This means that the total number of seats would be number of rows × number of columns
= 15 × 20 = 300 seats
All tickets cost $18 each. If all the seats are sold, that means that each seat cost $18 each.
Total amount of money collected for arena J would be total number of seats × the cost per seat.
Total amount of money collected for arena J = 300 × 18 = $5400
Answer:
Step-by-step explanation:
za/2: Divide the confidence interval by two, and look that area up in the z-table: .95 / 2 = 0.475. ...

Answer:
x=8 and y=3 (So, yes!)
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
−x+4y=4;−x+3y=1
Step: Solve −x+4y=4 for x:
−x+4y+−4y=4+−4y(Add -4y to both sides)
−x=−4y+4
-x/-1 = -4y+4/-1 (Divide both sides by -1)
x=4y−4
Step: Substitute 4y−4 for x in −x+3y=1:
−x+3y=1
−(4y−4)+3y=1
−y+4=1(Simplify both sides of the equation)
−y+4+−4=1+−4(Add -4 to both sides)
−y=−3
-y/-1 = -3/-1 (Divide both sides by -1)
y=3
Step: Substitute 3 for y in x=4y−4:
=4y−4
x=(4)(3)−4
x=8(Simplify both sides of the equation)
<u>Answer:</u>
x=8 and y=3
