Answer: Horizontal Asymptote: y = 7
Y = 3^x + 7
Step-by-step explanation:
Exponential functions have a horizontal asymptote. The equation of the horizontal asymptote is y = 7
Answer: it contains 200 grams of zinc.
Step-by-step explanation:
Ratio of zinc to copper is 4 to 15 = 4;15
Total ratio = 4+15= 19
We first find amount of both zinc and copper( the whole chemical) which is equal to
ratio of copper / total ratio x (the entire chemical--total grams of zinc and copper) =amount of copper
15/19 x X = 750
X= 750 X 19 / 15= 950 grams
To find amount of zinc in the chemical = ratio of zinc / total ratio x total amount of chemical
=4/19 x 950
=200 grams
Answer:
X can be anything below 4
Answer:
x = -3 or 9/4
Step-by-step explanation:
(x+3)(4x-9)
or use the quadratic formula
Answer:
Percy is incorrect
Step-by-step explanation:
I plugged in 9 and 8 for x and both of them did NOT solve it. The only number I know of that can solve it is -7. -7^2=49
-7 multiplied by 7 =-49
(49) + (-49) + 12 = 12
