Answer:
y =5x
Step-by-step explanation:
![y_{1}-y_{2} = m(x_{1} - x_{2} )](https://tex.z-dn.net/?f=y_%7B1%7D-y_%7B2%7D%20%20%3D%20m%28x_%7B1%7D%20-%20x_%7B2%7D%20%29)
(5 - 0) = m(1 - 0)
5 = m(1)
5 = m
![y_{1}-y_{2} = m(x_{1} - x_{2} )](https://tex.z-dn.net/?f=y_%7B1%7D-y_%7B2%7D%20%20%3D%20m%28x_%7B1%7D%20-%20x_%7B2%7D%20%29)
y - 5 = 5(x - 1)
y - 5 = 5x - 5
y = 5x -5 + 5
y = 5x
Answer: 32
Step-by-step explanation:
Answer:
0.80A + 0.92B = 63 .....1
A + B = 75 ......2
Step-by-step explanation:
Let A and B represent the total possible score in part A and B respectively;
Analysing each sentence of the question;
Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63
80% of A + 92% of B = 63
0.80A + 0.92B = 63 ......1
The total possible marks for the test was 75;
A + B = 75 .....2
So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.
Solving the simultaneous equations, we will arrive at;
Part A = 50
Part B = 25
