Answer:
all you need to do is fine the difference of the numbers
Step-by-step explanation:
<span>C.) y = 850(1.05)^x
It should be exponential grow.</span>
Work only with the second equation at the beginning. Solve for x for it.
7x - 2x = 3 Combine the left hand side.
5x = 3 Divide by 5
5x/5 = 3/5 Do the division
x = 3/5 = 0.6
==============
Now work with the top equation.
3(0.6) + 5y = 13 Multiply on the left.
1.8 + 5y = 13 Subtract 1.8 from both sides.
1.8 - 1.8 + 5y = 13 - 1.8 Do the subtraction
5y = 11.2 Divide by 5
5y/5 = 11.2/5
y = 2.24 Answer
Answer:
its C
Step-by-step explanation:
Answer:
q=4t^4+5/t^2x
Step-by-step explanation:Multiply both sides by t^2; Divide both sides by t^2x
