Answer:
a=11, b=53
Step-by-step explanation:
y=ax+b
x=1, y=64 -> 64=a+b
x=2, y=75 -> 75=2a+b
75-64=a, a=11, b=53
All the other points obey this rule.
There are 10,000 possible values the digits 0 and 9 can be arranged as a 4-digit number.
Answer:
110 + 10x ; 40x
4
Step-by-step explanation:
Given that:
For every visit to Arts museum:
Scenario 1:
Parking fee = $15
Admission fee = $25
Total amount for scenario 1:
If number of visits = x
Total cost = $(15 + 25) × number of visits
Total cost : $40x
With membership :
Price of membership = $110 (one time payment)
Parking fee = $10
Admission fee = $0
Let number of visits = x
Total cost :
Membership fee + (parking fee × number of visits)
$110 + ($10 * x)
= 110 + 10x
B) number of visits for which member cost is less than non-member cost :
Member cost = 110 + 10x
Non member cost = 40x
110 + 10x < 40x
10x - 40x < 110
-30x < 110
x > 3.67
Hence x = 4
Number of visits for which member cost is greater than non member cost is 4
Answer:
y=-3/4-5
Step-by-step explanation:
plug in ordered pair 1= -3/4(-8)+b
solve for b. b= -5
plug in to y=mx+b
