Answer:
1.5
Step-by-step explanation:
12 / 8 = 1.5
4t+2c=200
2t+7c=400
I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t
Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each
Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each
Hope this helps! :)
Answer:
3
Step-by-step explanation:
Answer: Correct answer is C -I just took the test
we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.
you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)
now we have:
g(x) = -f(x) = - 4(1/2)x
then the right answer is the third option:
g(x) = -4(1/2)x
