1)what is the y-coordinate of the solution to the system of equations?

x-y=12
27+3y=2x

2)what is the y-coordinate of the solution to the system of equations?

y=2x+14

-4x-y=4

Answers

Answer 1
Answer: ok so basically solve for y

x-y=12
27+3y=2x

27+3y=2x
subtract 3y from both sides
27=2x-3y
2x-3y=27

x-y=12
multiply by -2
-2x+2y=-24

add them
2x-3y=27
-2x+2y=-24 +
0x-1y=3

-y=3
y=-3
y coordinate is -3


2.
y=2x+14
-4x-y=4

y=2x+14
subtract 2x from both sides
y-2x=14
mulitply both sides by -2
-2y+4x=-28

add the 2 equations

-2y+4x=-28
-y-4x=4 +
-3y+0x=-24

-3y=-24
divide both sides by -3
y=8

y coordinate is 8





1. y coordinate is y=-3

2. y coordinate is y=8

When graphing an inequality how do you know whether the line should be solid or dotted? plz go into detail and if you have a specific way your remember it plz help i need it for my final exam.

Answers

well, when it comes to graphing an inequality, and you need to know whether the line is solid or dashed, look at the inequality sign.....   (i do not remember that exact terms)  anyway, if it is JUST > or < then it is dashed, that is because you are not including that number, just any number greater than or less than it...

however, if it is Greater than or Equal to 
or
less than or equal to
where these two are including that # by having the "or equal to", it will be solid for it is INCLUDING what ever # we are using...

for example

y > 3 will be dashed

where as     y is greater than or equal to 3 will be solid since the y could be 3

i cant really explain this well...   but i hope i made it somewhat clear

Add one term to the polynomial expression 14x^19 - 9x^15 + 11x^4 + 5x^2 + 3 to make it into a 22nd degree polynomial

Answers

The required polynomial to a 22nd degree is P(x)=x^(22)+14x^(19) - 9x^(15) + 11x^4 + 5x^2

Given the polynomial function, 14x^(19) - 9x^(15) + 11x^4 + 5x^2,, we are to add one term to the polynomial to make it into a 22nd-degree polynomial.

Note the highest and leading power of the variable of any function is the degree of such function.

To convert the given polynomial to a 22nd-degree function, we will simply add a variable term x with a degree of 22 to have:

P(x)=x^(22)+14x^(19) - 9x^(15) + 11x^4 + 5x^2

Hence the required polynomial to a 22nd degree is P(x)=x^(22)+14x^(19) - 9x^(15) + 11x^4 + 5x^2

Given:

The polynomial is

14x^(19)-9x^(15)+11x^4+5x^2+3

To find:

One term which is used to add in given polynomial to make it into a 22nd degree polynomial.

Solution:

Degree of a polynomial is the highest power of the variable.

Let,

P(x)=14x^(19)-9x^(15)+11x^4+5x^2+3

Here, the highest power of x is 19, so degree of polynomial is 19.

To make it into a 22nd degree polynomial, we need to need a term having 22 as power of x.

We can add kx^(22), where k is constant.

So add x^(22) in the given polynomial.

P(x)=x^22+14x^(19)-9x^(15)+11x^4+5x^2+3

Now, the degree of polynomial is 22.

Therefore, the required term is x^(22).
