Answer:

A is the correct answer

Step-by-step explanation:

When x =4 and y =-5, and you want to evaluate equation -3x+2y, you just have to apply it into the equation.

We got the equation as:

= -3x + 2y

= -3*4 + 2*(-5)

= -12 + (-10)

= -12 - 10

= -22

Hope this help you :3

Cloud [144]

Well a difference is the difference between them. difference means subtraction. So so a difference can be written as:
40.67 - (-41.29)

If you subtract a negative number you really add it. to make sense of this you could say 40.67 is 40.67 units away from zero in the positive direction. whereas -41.29 is 41.29 units away in the negative direction. since they go in opposite directions away from zero that means that thw length between them is extended and must then be added together. So
40.67 + 41.29 = 81.96
