The cost of the gas per gallon is $2.1 and the cost of the car wash is $6.

Step-by-step explanation:

Given the cost of the gas per gallon is dollars. And the charge of car wash is dollars.

Also, it was given that two cars fill up their tank and go for a car wash. We can write linear equation for each case.

One car pays $22.80. It uses 8 gallons gas and go for car wash.

Equation (1)

The other car pays $18.60. It uses 6 gallons gas and go for a car wash.

Equation (2)

substitute this value of in equation (1) we get,

Now, to find the value of we will plug value of in

So, the cost of the gas per gallon is $2.1 and the cost of the car wash is $6.

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
