Answer:
Small fish= 7
Big fish= 21/4 (so she'll get 5 big fish)
Step-by-step explanation:
With the problem, there are two equations, one for the cost, and one for the amount of water. For the first equation, Alaina can spend 70 dollars and the fish cost 8 and 3 dollars so the equation is 70=8b+4s (s for small and b for big). Then for the second equation there are 14 available gallons and the fish require 2 and .5 gallons so 14=2b+0.5s. Then you just solve the system of equations.
Since this is an arithmetic sequence, you can conclude that
the addition to the number is constant.
Let x = the number asked
k = constant
number added to the sequence
7 + k = x
x + k = 17
Solve the system of equation:
7 + k + k = 17
7 + 2k = 17
2k = 10
k = 5
Therefore, the missing number is 12 (7 + 5).
Answer:
x = 5y + 6
Step-by-step explanation:
Add 5y to both sides
x - 5y + 5y = 5y + 6 (variable always goes first)
-5y + 5y = 0
x = 5y + 6
The correct answer is letter A. It’s an exponential parent function. They are always curved like that.
Two figures are similar are one of them can be obtained from the other with some transformations (reflections, translations, rotations, dilations) <span> . The circle is defined by only one length - the radius.

To prove that all circles are similar you would use the sequence of similarity translation and dilation.
A translation, followed by a dilation with scale factor r2/r1 will map one circle onto the other, thus proving that the circles are similar.
