Answer:
it is a linear expression
Answer:
W (3 , 4) or W (3 . -4)
Step-by-step explanation:
W (3 , y), origin (0 ,0)
WO = √(3-0)²+(y-0)² = √9+y²
WO = 5
√9+y² = 5
9+y² = 25
y² = 16
y = ± 4
W (3 , 4) or W (3 . -4)
Step-by-step explanation:
To find the answer we first multiply 129 by 0.7 since the price descresed 30 percent. each percent is equal to 0.01.
129 * 0.7 = 90.3
Then we multiply 90.3 by 1.0875 since that is the sales tax
90.3 * 1.0875 = 98.2
so the cost is 98.2
