The answer to your question would be: Because 4 + (-7) is an equivalent expression, your answer is -3. The reason for this can be described using integers. So lets say you have $4. You owe your brother $7. Since you don't have enough to pay him, you can pay him all your money, but you still have to pay him $3 more. This means technically your balance is $-3, cause if he needs the money, the second you get it he will ask for it. Sorry if this isn't too great of an example, not sure what else I could think of. Pretty much remember when subtracting a number, you can add the negative of the number, because that is the same thing. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine). Thanks, it really helps! :D
Answer:
10 books approx
Step-by-step explanation:
Step one:
Given data
Hight of cupboard= 1.21m
Thickness of book= 12.5cm
thickness in meters= 12.5/100= 0.125m
Required
The number of books need to fill the Cupboard
Step two:
the number of books can be computed as
= 1.21/0.125
=9.68 book
=10 books approx
Answer:
C
Step-by-step explanation:
Answer:

Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

Two points are given: (-6,4) and (-2,2). Calculating the slope:

The equation of the line is, so far:

To calculate the value of b, we use any of the given points, for example (-6,4):


Solving:
b = 1
The equation of the line is:

We can see none of the choices is correct.
