Answer:
- The initial value corresponds to the y value when x = 0
Step-by-step explanation:
Since the graph is given, it is unnecessary to "finish the line." It is only necessary to read the value of y from the graph where x=0.
The mean of the numbers is c. 67
So first create and define your variables:
Z = amount of zebra fish
N = amount of neon tetras
Now create your equations:
2z+2.15n=31.20
z+n=15
This is your system. There are multiple methods to use but in this problem I’ll use the substitution method by simplifying the bottom equation.
2z+2.15n=31.20
z=15-n
Now I’ll plug the bottom equation into the top one.
2(15-n)+2.15n=31.20
And just solve from here.
30-2n+2.15n=31.20
0.15n=1.20
n=8
So he bout 8 neon tetras, and 15-8= 7, so he bought 7 zebra fish
12a) yes, there will be two vanilla cupcakes left over after the baker makes ten more.
A fraction in which the factor of the numerator and the denominator is 1 is known as a <span>reduced, or simplified, fraction.
</span>
<span>68 is not reduced (or not simplified) because 68 =2⋅32⋅2⋅2
</span>
<span>34 is a reduced, or simplified, fraction: 1⋅31⋅2⋅2</span>
