What would -2 - (-7) be? And how would you do that

Mathematics

zavuch27 [327]3 years ago
8 0

Answer:

5

Step-by-step explanation:

Okay, so adding negative numbers can get very tricky, but I think I can help

Since there are two negative signs next to each other, they both cancel out and become positive so instead you get

-2+7

And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5

I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!

Someone help me determine whether the statement is true or false
enyata [817]

Answer:

The Statement D⊆B  is False.

Step-by-step explanation:

Given:

A = {1, 3, 5, 7 }

B = {5, 6, 7, 8}

C = {5, 8}

D = {2, 5, 8}

U = {1, 2, 3, 4, 5, 6, 7, 8}

To Check:

D⊆B = True or False

Solution:

The sign '⊆' symbolize  SUBSET

So D⊆B means D is the Sub Set of B

That means All the element of Set D must be there in the SET of B Then it comes True.

Or else it is False

D = {2, 5, 8}

B = {5, 6, 7, 8}

Therefore D⊆B is a FALSE statement

For it to be TRUE we must have set B as

D = {2, 5, 8}

B = {2,5, 6, 7, 8}

Now D⊆B is a TRUE statement

The grocery store is located at a point on a coordinate plane with the same y coordinate as the bank but with the opposite x coo
Cerrena [4.2K]
The vertical axis on a graph is the y-axis and the horizontal axis is the x-axis. Keeping this in mind, if they have the same y coordinate that means vertically they are on the same level but their x coordinates are opposite each other, this means 2 things:
1. they are not on the same level horizontally 
2. you have to cross the vertical (y) axis to get from one point to the other.

So to answer your question, These two points are reflected across the y axis.

Hope this helps.

The Hickory Stick has a selection of 3 meats and 6 vegetables. How many different selections of one meat and one vegetable are p
valentina_108 [34]

The <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.

Since the Hickory Stick has a selection of 3 meats and 6 vegetables, the number of ways we can select <u>one </u>meat out of 3 is ³C₁ = 3.

Also, the number of ways we can select <u>one </u>vegetable out of 6 is ⁶C₁ = 6.

So, the total number of selections of <u>one</u> meat and <u>one</u> vegetable is ³C₁ × ⁶C₁ = 3 × 6

= 18 selections

So, the <u>different</u> selections of<u> one</u> meat and <u>one</u> vegetable are possible are 18 selections.
