Variable x is 7 more than variable y. Variable x is also 1 less than y. Which of the following pairs of equations best models the relationship between x and y?
A x = 1y, x = y + 7
B x = y + 7, x = y − 1
Cy = x + 8, y = x − 1
y = 7x, y = x + 1
The answer is B x = y + 7, x = y − 1
OK thank you. Can you answer one more?
Shiloh is 7 years older than Courtney. Shiloh's age is 13 years less than two times Courtney's age. The system below models the relationship between Shiloh's age (s) and Courtney's age (c): s = c + 7 s = 2c − 13 Which of the following methods is correct to find Shiloh's and Courtney's age?
A:Solve s + 7 = 2s − 13 to find the value of s.
B:Solve c + 7 = 2c − 13 to find the value of c.
C:Write the points where the graphs of the equations intersect the x-axis.
D:Write the points where the graphs of the equations intersect the y-axis.
The answer is B
Do you have the time to do one more?
