You subtract 16 from each side of the equation.
Then it will say exactly what number 'n' is.
_______________________________________
The equation is n + 16 = 9
On the left side, you subtract 16 from (n + 16) and you have 'n'.
On the right side, you subtract 16 from 9 and you have -7 .
Now the equation says n = -7
Answer:
x=-5, y=-1
Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15
8-2y-5y=15
-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.
Answer:
He actually paid a sum of $201.25
Step-by-step explanation:
We simply add the vat value to the cost of the machine
Mathematically, that’s (
175 + 15% of 175
= 175 + (15/100 * 175)
= 175 + 26.25
= $201.25
The function represented by the table is given by the rate of change of
the <em>x</em> and y-values which are constant indicating a linear function.
Response:
The statement that could be used to justify that the table represents a linear function is as following;
- The y-values decrease by the same amount
<h3>How to determine if a table represents a linear function?</h3>
The table of of a linear function is one in which the first difference in
the y-values is constant given that the difference in the x-values are also
constant.
From the table, the first difference between each y-value and the
previous y-value is found as follows;
20 - 35 = -15
5 - 20 = -15
-10 - 5 = -15
While the difference between the corresponding x-values = 1 as follows;
0 - (-1) = 1
1 - 0 = 1
2 - 1 = 1
Therefore;
The (rate of) change in the <em>x</em> and <em>y</em> -values in the table are constant, and
the function is a linear function.
The correct statement is therefore;
- The y-values decrease by the same amount
