5-(-4)=5+ write as addition

Mathematics
1 answer:
Furkat [3]4 years ago
5 0

Answer:

5+4

Step-by-step explanation:

Based off the typical rules of integers, expressions like these can be simplified to look different but mean the same thing.

5 - (-4) = 5+4

In this case, we subtracted a negative value from a positive value; by doing this, we actually added positive 4.

Based on the same principals, adding a negative number is equivalent to subtraction!

Any time you see equations similar to this, you want to cancel out the 2 negative signs to make it positive!

What are the slope and the y-intercept of the linear function that is represented by the equation y=9x-2? The slope is –2, and t
MatroZZZ [7]

Hello there!

Answer:

The slope is 9, and the y-intercept is –2

Step-by-step explanation:

The equation is y = 9x - 2

This follows the equation y = mx + b

Where as:

m = slope

b = y-intercept

When you know this, you would figure out that 9 is in the same place as m, and -2 is in the same place as b.

The y-intercept would not be a positive 2 because when there's a minus sign next to the number in the y-intercept spot, then you would have to bring that over to the number. We can also say the minus sign belongs to the 2, making it a -2.

With the information we know now, we can say that the slope of the equation is 9, and the y-intercept would be -2.

Therefore, giving your answer as "The slope is 9, and the y-intercept is –2"

Twice the sum of a number and 77 is equal to three times the difference of the number and 6.  Find the number
tino4ka555 [31]

x + 77 = 3(x - 6)

x + 77 = 3x - 18

x + 77 + 18 = 3x - 18 + 18

x + 95 = 3x

x + 95 - x = 3x - x

95 = 2x

x = 95/2

x = 47.5

Scilla [17]

216 x 3 = 648

If you want to add the hot dogs to that number it would be 864

3 times 216 is 648 cans of soda

plus 216 of hot dogs

so you have 216 hot dogs and 648 sodas
