Answer:
(3,2)
Step-by-step explanation:
the other three ordered pairs do not lie in the shaded region
Given, local sales tax rate = 7%
The selling price of car = $26,200
Now to find the sales tax for the car we have to find 7% of $26,200.
7% of 26,200 = 26200×(7/100) = (26200×7)/100 = 183400/100 = 1834
So the total sales tax paid = $1834
Now to get total cost of the car we have to add the sales tax we have got with the selling price of the car.
So, the total cost of the car = Selling price of the car + sales tax
= $26,200 + $1834
= $28,034
So we have got the required answers
Sales tax = $1834 and total cost of the car = $28,034
Answer:
Step-by-step explanation:
4.2x+4.7=18.6
Multiple each term by 10
42x + 47 = 186
Collecting like terms
42x = 186 - 47
42x = 139
x = 139/42
x = 3 13/42 or 3.3
The answer to this is 6 cm, B
Answer:
x = -4/7, y = 2/7
Step-by-step explanation:
Given: f(x) = 3x + 2 and g(x) = - 4x - 2
The point of intersection of the two functions is the point at which both functions intersect. We have to solve the functions simultaneously to get the solution.
f(x) = y = 3x + 2
y = 3x + 2 (1)
g(x) = y = -4x - 2
y = -4x - 2 (2)
Subtract equation 2 from equation 1:
0 = 7x + 4
7x = -4
x = -4/7
Put x = (-4/7) in y = 3x + 2:
y = 3(-4/7) + 2 = -12/7 + 2 = 2/7
