The gradient of the line is 2.5, the y-intercept is 5.
The equation representing the line is y = 2.5x + 5
Based on the concept mentioned in my previous answers to your questions, this means the shaded region is represented by y ≤ 2.5x + 5
Answer:
= y > -272

Answer:
g(f(3)) = 0
Step-by-step explanation:
f(x) = 2x - 9
f(3) = 2(3) - 9
f(3) = -3
g(-3) = 9 - (-3)^2
g(-3) = 9 - 9
g(-3) = 0
To answer the question, let x be the cost of a bedsheet and y that of a towel. The first purchase can be expressed as,
38x + 61y = $791.50
and the second as,
54x + 50y = $923
Solving for x and y simultaneously will give, x = $12 and y = $5.5. Thus, each bedsheet costs $12 and each towel cost $5.5.
