Step-by-step explanation:
9p*30days= 45p
45÷100=0.45£
The correct answer would be No fine is paid if the DVD is returned by the due date, because the first 0 means it is 0 days overdue, so it is returned on time, and the second 0 means the fine would be $0!!

x + 3y - 5
-2x + 2y = 14
Answer:
y = 3
x = -4
Step-by-step explanation:
Hopefully the first equation is x + 3y = 5
x = 5 - 3y
Plug in:
-2(5 - 3y) + 2y = 14
-10 + 6y + 2y = 14
8y = 24
y = 3
x = -4
Answer:
Here we have:
IxI < 7
This also can be written as:
-7 < x < 7
and:
IyI < 2.
As above, we can write this as:
-2 < y < 2.
Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)
Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.
The area would be the area inside that rectangle, where i did not shade it so it is easier to read.
To sketch and shade the region defined by the inequalities |x| < 7 and |y| < 2, identify the boundaries and sketch the rectangle, shading the region within it.
To sketch and shade the region defined by the inequalities |x| < 7 and |y| < 2, we first identify the boundaries of the region. The inequalities |x| < 7 and |y| < 2 represent lines parallel to the x-axis and y-axis, respectively. The region is bounded by these lines and lies within the rectangle with vertices (-7, -2), (-7, 2), (7, -2), and (7, 2). We sketch the rectangle and shade the region within it.

Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between triangle sides and trig functions. These abbreviations tell you that ...
Sin = Opposite/Hypotenuse ⇒ sin(x) = b/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = a/c
Tan = Opposite/Adjacent ⇒ tan(x) = b/a

Step-by-step explanation:
The total number of miles hiked will be the sum of the numbers of miles hiked each day. Each day, the number of miles hiked can be computed by multiplying time by speed:
distance = speed × time
So, the total number of miles hiked is ...
total miles = miles on day 1 + miles on day 2 . . . . . (sum, not a difference—eliminates choice B)
total miles = (speed on day 1)×(time on day 1) + (speed on day 2)×(time on day 2) . . . . . (sum of products—eliminates choices C and D)
Choice A correctly describes the computation.
x+6y=-3
Would you rather use subtraction or addition to solve the system? Explain
your reasoning. (Lesson 2-14)
It is more convenient to use addition to solve the system of equations as it eliminates one of the variables when the equations are added. The solution to the system of equations is x = -6 and y = 1/2.
To solve the given system of equations, it is generally more convenient to use addition rather than subtraction. This is because addition eliminates one of the variables when the equations are added together, making it easier to solve for the remaining variable. Let's see how:
Adding the two equations together eliminates the 'x' variable:
-x + 6y + x + 6y = 9 + (-3)
12y = 6
Now, we can solve for 'y' by dividing both sides by 12:
y = 6/12 = 1/2
Substituting the value of 'y' back into either of the original equations, we can solve for 'x':
-x + 6(1/2) = 9
-x + 3 = 9
-x = 6
x = -6
Therefore, the solution to the system of equations is x = -6 and y = 1/2.
