Step-by-step explanation:

5/7x - 14 = -22

5x -98 = -154

5x = -154 + 98

5x = -56

x = -56/5, -11 1/5, or -11.2

Answer:

x= -11.2

5/7x-14=-22

      +14 +14        Add 14 on both sides

5x + 10y = -5
-5 - y = 32

Answers

y= -27
x= 53

solving for y:

-5-y=32

add y to both sides

-y = 27

divide by -1

y= -27

solving for x

plug in -27 for y in the first equation

5x +10(-27) =-5

5x+ (-270) =-5

add 270 to both sides

5x= 265

divide by 5 on both sides

x= 53

x = 7
(6)(7) + 10 = 52
42 + 10 = 52

Answer:

7

Step-by-step explanation:

well let’s just think that there’s already 10. let’s ignore the 10 for later.

now let’s think about 6x. of course the x is unknown (variable) which we have to find, so what you want to do, (easy way) think of every multiple of the number 6. so that of course includes 6, 12, 18... etc. now if you continue, you will get to the number 42. now it might not click right there but 42... is what we need since we already have the 10. since 42 + 10 = 52, now we just need to find out what 42 divided by 6 is... 7! 7x6 or 7(6) is 42, plus the starting 10 is 52!

therefore, x = 7.

Name this polynomial by its degree: 3x² + 5x-3

Answers

Answer:

[tex]\boxed{\textsf {The given polynomial is a quadratic polynomial. }}[/tex]

Step-by-step explanation:

A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

[tex]\sf\implies p(x)= 3x^2+5x-3 [/tex]

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .

★ More to Know :-

When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.

That is ,

[tex]\sf\implies p(x)= 3x^2+5x-3=0[/tex]

This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

The name is a Quadratic polynomial
