Consider f(x) = 1.8x – 10 and g(x) = −4. select the equation that can be used to find the input value at which f (x ) = g (x ), and then use that equation to find the input, or x -value.

Which system of linear inequalities is graphed? can somebody pleasssse

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
