Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65
Answer:
the total number of blocks is 69
Step-by-step explanation:
the way you can find this is by counting all the outside blocks on the closest side (23) and multiplying it by the the width of the blocks on the right side (3)
The answer is a.
eliminate c and b because that's wrong then identify the dependent quantity.
Part A:
Phone A has a $8.75 discount
$175*0.05=$8.75
Phone B has a $40.00 discount
$200*0.20=$40
Part B:
Phone A is $166.25
$175-$8.75=$166.25
Phone B is $160.00
$200-$40=$160
Part C:
Phone B costs less after the discount
Part D:
No, sales tax is applied to the discounted/final price, so both prices will increase by 6%. Phone B will still be cheaper.
