Answer:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$

Step-by-step explanation:

Given

$y = 4x - 1$

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

$y = 4*-2 - 1 = -9$

When x = 0

$y = 4*0 - 1 = -1$

When x = 2

$y = 4*2 - 1 = 7$

When x = 4

$y = 4*4 - 1 = 15$

So, the table is:

$\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]$

How can you isolate the variable in x-3 = 7

anzhelika [568]

Answer:

x = 10

Step-by-step explanation:

To isolate the variable (x) you would first write out x - 3 = 7. Now to make x on its own we have to get rid of the -3 so to do that we would add the reciprocal of -3 (or the opposite) which is +3. x - 3 + 3 = 7 + 3 or x = 10.
