Evaluate: 8 - 9+(-2)

Mathematics
1 answer:
Kobotan [32]3 years ago
5 0
Evaluate : 8 - 9 + (-2)



8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)

-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)

Finally, your answer to this question is -3.

What is the gradient?
notsponge [240]

Answer:

Gradient = 2

Step-by-step explanation:

Gradient of a line = Slope of the line

Since, slope of a line passing through two points (x_1, y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Given line in the graph passes through two points (1, 0) and (2, 2)

Therefore, slope or gradient of the line = \frac{2-0}{2-1}

                                                                  = 2

Gradient = 2 will be the answer.

Can you evaluate the expressions for the given value. (show steps if you can)
exis [7]

Answer:

Q1. -45

Q2. -10

Q3. 31?

Step-by-step explanation:

Q1 -- you times -8 and 2 which comes out to -16. Since you have -16 + 1 inside of the parentheses you add 1 to -16 which comes out to -15. Then you take -15 times 3 and it comes out to -45.

Q2 -- the m gets replaced by the 5 so now its -2 times 5. Which comes out to -10. Then you take -10 times 2, which is -20. Now take -20 + 10 which gives us the answer of -10.

Q3 -- I'm not completely sure on this one but I think the equation would transfer to this 2*5 + 5*3 + 2*3. So 2*5 is 10, 5*3 is 15, and 2*3 is 6. Add them all together and you get 31.

I hope this was right and it helps you!
