Answer: 675
m represents the time she has been paying. And B represents how much she owed.
So to find how much she owed at the beginning, when no time had passed, we need to set m equal to zero.
When m is zero, the equation is
B = -100(0) + 675
B= 675
So 675 is how much she owed at the beginning of the year.

Answer:
43.83cm
Step-by-step explanation:
There are only two faces that are 25cm by 36cm, the top and the bottom face. Since, the ant, cannot move across the bottom face, we are left with the top face which is a rectangle. The shortest distance is through the diagonal.
Drawing a diagonal, you have two right-angled triangles. Bringing any out, we would need to know the length of the diagonal which is the hypotenuse of the right angle triangle. Using Pythagoras theorem:
(Hypotenuse)^2 = (opposite)^2 + (adjacent)^2
H^2 = 25^2 + 36^2
H^2 = 625 + 1296
H^2 = 1921
H = sqrt (1921)
H = 43.83 cm (to 2 d.p.)
H which represents the hypotenuse, that is the diagonal is the shortest distance. Hence, the shortest distance is 43.83cm.
Answer:
x = 2 and y = 1
Step-by-step explanation:
First, solve for y by substituting the second equation as x into the first equation
-2x - 3y = -7
-2(y + 1) - 3y = -7
Simplify and solve for y
-2y - 2 - 3y = -7
-5y - 2 = -7
-5y = -5
y = 1
Solve for x by plugging in 1 into the second equation
y + 1 = x
1 + 1 = x
2 = x
So, the answer is x = 2 and y = 1
