Using Pythagorean theorem, the answer should be D
Answer:Angle A is equal to 113
Step-by-step explanation:
If two angles are vertical, that would make them equal to each other.
7x-20=6x-1
Add on to both sides
7x-19=6x
Subtract Seven from both sides
-19=-x
Divide by negative one to get rid of the negative
19=x
Then plug x into the equation 7(19)-20
112
84 times 4/3= 336/3=112
Answer:
Step-by-step explanation:
xy = k
where k is the constant of variation.
We can also express the relationship between x and y as:
y =
where k is the constant of variation.
Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = .
Example 1: If y varies inversely as x, and y = 6 when x = , write an equation describing this inverse variation.
k = (6) = 8
xy = 8 or y =
Example 2: If y varies inversely as x, and the constant of variation is k = , what is y when x = 10?
xy =
10y =
y = × = × =
k is constant. Thus, given any two points (x1, y1) and (x2, y2) which satisfy the inverse variation, x1y1 = k and x2y2 = k. Consequently, x1y1 = x2y2 for any two points that satisfy the inverse variation.
Example 3: If y varies inversely as x, and y = 10 when x = 6, then what is y when x = 15?
x1y1 = x2y2
6(10) = 15y
60 = 15y
y = 4
Thus, when x = 6, y = 4.
2nd answer choice
constant of variation is xy. XY=23. If X=7 then Y=23/7.
Answer:
The new balance will be $385.04.
Step-by-step explanation:
Previous balance = $179.32
Payments/credits = $85.00
Unpaid balance = 
= $264.32
Monthly rate = 1.25%
Finance charge = 
= $3.30
New purchases = $117.42
New balance = 
= $385.04
