We need a picture of the graph
<span>4(2x - 5) = 4
8x - 20 = 4
8x = 4 + 20
8x = 24
x = </span>

x = 3
Part A:This equation has only one solution. {Working shown above}
Part B:The solution is x = 3. {Working shown above}
A function is shifted vertically upwards/downwards by adding/subtracting a constant value to the function.
In this case f(x) was shifted upwards by 3 units.
I recommend you use google because these are very easy
Answer:
Step-by-step explanation:
Number of candies that her sister gave = x
Total candies that Pam has now = 27
x + 15 = 27
<h3>Inverse operation:</h3>
x + 15 = 27
x + 15 - 15 = 27 - 15
x = 12
