Evaluate each function for the given input values. 6. For f(x) = x + 7, find f(x) when x = 3 and when x = -5.
7. For g(x) = -2x, find g(x) when x = 4 and when x = -1.
8. For h(x) = 3x - 1, find h(x) when x = -2 and when x = 7.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

i dont know sorry

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
