HELP I Will mark brainliest if you explain

Mathematics
1 answer:
Aleksandr [31]3 years ago
8 0

Answer:

(0,5)

(2,1)

(4,-3)

Step-by-step explanation:

so all you have to do is plug in the x value and if the y value comes out to be whatever is matches up with then it is a solution to the equation for example if you plug in 0 to y=-2x+5 then you get 5 and below it says that when x=0 then y=5 which is true so that would be an answer now if you plug in 2 then you get 1 and it says that when x=2 y=9 which is not correct. sorry if this doesnt make sense its so hard to explain virtually

A bookcase has 6 shelves.
xeze [42]

Answer:

21 books are on each shelf.

Step-by-step explanation:

To solve this you need to divide 130 and 6 so you should get 21 with a remainder of 4 which is the amount of books on each shelf and the amount of books that are left over.

I hope this helps :D

How do I do this? Help????!!!
mylen [45]
A = 9 because 11.2-2.2=9
B= 2.2 because 9+2.2=11.2
C=2.2 because 11.2-9=2.2
D=9.2 because 11.2-2=9


E=4.5 because 9.5-5=4.5
F= 5 because 9.5-4.5=5
G=4.5 because 9.5-5=4.5
H=5 because 9.5-4.5=5

I= x=11 because 99 divided by 9 = 11
J= x=9 because 99 divided by 11 = 9
K= 9 because 99 divided by 11 =9
L= 11 because 99 divided by 9=11

M=2 because 4 divided by 2 =2
N=4 because 2 times 2 =4
O=2 because 4 divided by 2 =2
P=2 because 4 divided by 2=2


hope this helps:)

If a =5, 0, −1,find a vector b such that compab = 2.b = _______.
Arturiano [62]

Answer:

b  =  (q,r , 5q-2\sqrt{26} )

Step-by-step explanation:

From the question we are told that

The vector given is  

               a = (5,0,-1)

  Also  comp_a b =  2

Generally

       comp_a b  =  \frac{a \cdot b}{|a|}

Here  |a| is the magnitude of  a which is mathematically represented as

      |a| =  \sqrt{5^2  + 0^2  +(-1)^2 }

=>     |a| =  \sqrt{26}

b is vector which we will assume to have the following parameters

     b  =  (q , r , x)

So

        comp_a b =  \frac{(5,0,-1) \cdot (q,r,x)}{\sqrt{26} } =  2

=>     \frac{5q + 0 -x}{\sqrt{26} } = 2

=>     x =  5q-2\sqrt{26}

Hence the vector be can be mathematically represented as

      b  =  (q,r , 5q-2\sqrt{26} )

This means that the vector b is more than one value  since it is made up of variable

This means that if

   q = 1\\r=1\\x =1

Then

    b  =  (1,1,5-2\sqrt{26} )
