Answer:
y= -4x + 21
Step-by-step explanation:
Answer:
0.85x - $50
Step-by-step explanation:
Given that :
Brandon wants to buy a new bike. The model he likes is on sale for 15% off its original price. His parents agree to pay for $50 of the cost. If the original cost of the bike is x dollars, which of the expressions below represent the amount Brandon has to pay
Discount on price = 15%
Amount parents agreed to pay = $50
Cost of bike = x
Discount on bike = 0.15x
Cost after discount is removed = (x - 0.15x) = 0.85x
Parent pays $50 of cost price, amount Brandon will have to pay equals :
(0.85x - $50)
B) 30
if you go down 1,000 then that means -10
if you go up 3,000 than that means +30
In order to calculate the probability of this, you need to multiply the probability of each event. The chance of him rolling heads is 1/2, the chance of him getting a 4 is 1/6. Multiply them together to get 1/12 or 8.3333...%
Hope you understand!
