Answer:
k = 2
Step-by-step explanation:
Fill in the given point values and solve for k.
y = (1/2)x + k
1 = (1/2)(-2) +k . . . . . . for x = -2, y = 1
1 = -1 +k . . . . simplify; next, add 1
2 = k
The answer is C: multiply by 2
Answer: $24.50
Post office:£1 = $1.27
£350 = $1.27 × 350 = $444.50
Bank:£1 = $1.34
£350 = $1.34 × 350 = $469
Therefore, the difference will be:
= $469 - $444.50
= $24.50
