Answer:
Negative, because the product (-7)(-2) is positive, and the product (-5)(1) is negative and the product of a positive and a negative number is negative
Step-by-step explanation:
Negative, because there is an odd number of negative factors. The above explanation is reasonable, too.

System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
Answer and Step-by-step explanation:
Every episode is 20 minutes. The points would be:
- (40, 2)
- (80, 4)
- (120, 6)
- (160, 8)
8x-2(4)=48 Then, 8x-8=48 Then, 8x=56 Then X=7
The value of x in the equation is 7.
