The graph represents a linear function.
The amount left to pay after the eight month is (d) (8,y)
From the question, we have:
On the graph, we have the following observations
- The x-axis represents the number of months
- The y-axis represents the amount left to pay
So, the amount left to pay, after the first month is (1,y) -- as seen on the graph
Similarly, the amount left to pay after the eight month would be (8,y)
Hence, the true option is: (d) (8,y)

Answer:
The price of the jacket was $31.43
Step-by-step explanation:
Let the cost of a jacket = x
Let the cost of a pair of pants = y
Such that,
x + y = $66.12.........Equation 1.
From the conditional statement,
x = y - $3.26..........Equation 2.
Solve both equations simultaneously, using the substitution method
From Equation 2;
x = y - 3.26
Substitute y - 3.26 for x in Equation 1.
x + y = 66.12, now becomes,
y - 3.26 + y = 66.12
collect like terms
y + y = 66.12 + 3.26
2y = 69.36
y= 69.36/2 = $34.69.
Put y = $34.69 in Equation 2. to obtain x
x = 34.69 - 3.26
x = $31.43
Profit = Revenue - Cost = R(x) - C(x) = (x^2 + 20x + 50) - (50x + 30) = x^2 - 30x + 20
Answer:
Option A.) 1.30
Step-by-step explanation:
we know that
The secant of x is 1 divided by the cosine of x:
so
sec(40°)=1/cos(40°)
using a calculator
sec(40°)=1.30
Yes, felt that. thanks and have a lovely day!:D
