Use the function rule to complete the table -10x+y=4 table x= -2,-1, 0, 1, 2
I think the answers might be -2=-16/ -1=-6
0,4/ 1,14/ 2,44
Please tell if I’m right.
arrange the equation -10x+y=4 to
y = 10x + 4 , that way you can do your calculations in your head,
just take the x, multiply by it by 10, then add 4
so when x = -2, y = (-10)(-2)+4 = 20+4 = 24
when x = -1, y = 10+4 = 14
continue
you might notice that as x increases by 1, the y decreases by 10
Well, well, well, let's see if your table is a joke or a masterpiece!
If we substitute x = -2 into the equation -10x + y = 4, we get:
-10(-2) + y = 4
20 + y = 4
y = 4 - 20
y = -16
Now let's try x = -1:
-10(-1) + y = 4
10 + y = 4
y = 4 - 10
y = -6
Moving on to x = 0:
-10(0) + y = 4
0 + y = 4
y = 4
For x = 1:
-10(1) + y = 4
-10 + y = 4
y = 4 + 10
y = 14
Lastly, for x = 2:
-10(2) + y = 4
-20 + y = 4
y = 4 + 20
y = 24
So the correct table is:
x | y
-2 | -16
-1 | -6
0 | 4
1 | 14
2 | 24
So, my friend, it looks like you slightly miscalculated! But don't worry, you were close. Keep practicing your math skills, and before you know it, you'll be the king or queen of functions!
To complete the table using the function rule -10x+y=4, substitute the given values of x and solve for y.
For x = -2:
-10(-2) + y = 4
20 + y = 4
y = 4 - 20
y = -16
So, for x = -2, y = -16.
For x = -1:
-10(-1) + y = 4
10 + y = 4
y = 4 - 10
y = -6
For x = -1, y = -6.
For x = 0:
-10(0) + y = 4
0 + y = 4
y = 4 - 0
y = 4
So, for x = 0, y = 4.
For x = 1:
-10(1) + y = 4
-10 + y = 4
y = 4 + 10
y = 14
For x = 1, y = 14.
For x = 2:
-10(2) + y = 4
-20 + y = 4
y = 4 + 20
y = 24
For x = 2, y = 24.
The completed table should look like this:
x | y
-2 | -16
-1 | -6
0 | 4
1 | 14
2 | 24
So, the answers you provided are incorrect. The correct answers are:
-2 | -16
-1 | -6
0 | 4
1 | 14
2 | 24
To use the function rule to complete the table, we need to substitute the given values of x into the equation -10x + y = 4 and solve for y.
Let's substitute x = -2 into the equation:
-10(-2) + y = 4
20 + y = 4
y = 4 - 20
y = -16
So, when x = -2, y = -16.
Now let's substitute x = -1 into the equation:
-10(-1) + y = 4
10 + y = 4
y = 4 - 10
y = -6
So, when x = -1, y = -6.
Now let's substitute x = 0 into the equation:
-10(0) + y = 4
y = 4
So, when x = 0, y = 4.
Now let's substitute x = 1 into the equation:
-10(1) + y = 4
-10 + y = 4
y = 4 + 10
y = 14
So, when x = 1, y = 14.
Finally, let's substitute x = 2 into the equation:
-10(2) + y = 4
-20 + y = 4
y = 4 + 20
y = 24
So, when x = 2, y = 24.
The completed table is as follows:
x | y
-2 | -16
-1 | -6
0 | 4
1 | 14
2 | 24
Based on the calculations above, the answers you provided are incorrect. The correct answers are:
-2 | -16
-1 | -6
0 | 4
1 | 14
2 | 24
