The table of possible values when graphing
X Y
-2 9
-1 5
0 1
1 -3
2 -7
The intercepts x (1/4,0) and y (0,1)
Answer:
-25
Step-by-step explanation:
The following are x-values (inputs) and their y-values (outputs) that are one value apart:
(Input, output)
✅(-2, 20) and (-1, -5)
Difference between their outputs = -5 - 20 = -25
✅(-1, -5) and (0, -30)
Difference between their outputs = -30 -(-5) = -25
✅(0, -30) and (1, -55)
Difference between their outputs = -55 -(-30) = -25
✅(1, -55) and (2, -80)
Difference between their outputs = -80 -(-55) = -25
As we can see the difference of outputs for any two inputs that are one value apart = -25
Answer:
Step-by-step explanation:
80 -15 =65 so she would get 65 pencils back
Answer:
6 in
Step-by-step explanation:
In order for the inverse to exist, the matrix cannot be singular, so we need to first examine the conditions for existence of the inverse.
Compute the determinant. The easiest way might be a cofactor expansion along either the first row or third column; I'll do the first.

The matrix is then singular whenever

.
With this in mind, compute the inverse.
