The function g is defined by g(x)=cx-3, where c is a constant. Find c if the value of g(x) at x=0.5 is equal to -1

Answers

Answer 1

Answer:

Answer:

c = 4

Step-by-step explanation:

In g(x)=cx-3 when x is set to 0.5 , g(x)= -1.

We can solve for "c" when it is the only variable in the equation.

Substitute x for 0.5 and g(x) for -1. Isolate "c" to solve by doing reverse operations.

g(x) = cx - 3

g(0.5) = 0.5c - 3 Substitute x=0.5

-1 = 0.5c - 3 Substitute g(0.5) = -1

-1 + 3 = 0.5c - 3 + 3 Add 3 to both sides to start isolating c

2 = 0.5c

2/0.5 = 0.5c/0.5 Divide both sides by 0.5 to isolate c

4 = c Value of c

c = 4 Standard formatting puts the variable on the left side

Therefore the value of c if g(0.5)=-1 is 4.

Answer 2

Answer:

Answer:

c = 4.

Step-by-step explanation:

Substitute the given values x = 0.5 and g(x) = -1:

-1 = c(0.5) - 3

0.5c = -1 + 3 = 2

c = 2/0.5

c = 4.

Felipe is planning a party. He has $50.00 to spend on sandwiches that cost $2.50 per person, $25.00 to spend on drinks that cost $1.50 per person, and $25.00 to spend on gift bags that cost $3.00 per person. Which expression could be used to show the amount of money he will have left over if x people attend the party.a.50+7x
b.100-7x
c.250x+1.50x+3.00x
d.100-(2.50x-1.50x-3.00x)

Answers

It would be b. In all, he has $100 to spend since $50+$25+$25=$100. We have x people coming and he has to spend $2.50, $1.50, and $3.00 per person, respectively. The phrase "per person" indicates we must multiply, so we have to multiply each value by "x." To find out how much money he has left, we must subtract. All of this put together is 100-(2.50x+1.50x+3.00x).Add the like terms and you get 7x. Your final expression would be100-7x, which is answer choice b.
