This is 2/3.



This is 3/5.



They’re pretty similar, but you can tell that more is shaded in the first than the second. If they’re 8 though, then they’re probably in 2nd or 3rd grade. They’ll get it.

What is the leading coefficient of the polynomial?
ANEK [815]

ANSWER

B) 15

EXPLANATION

The given polynomial is

23 {x}^{5}  + 12 {x}^{2}  + 19 { x }^{3}  + 15 {x}^{6}

We arrange this polynomial in ascending powers of x to obtain the standard form;

15 {x}^{6} + 23 {x}^{5}    + 19 { x }^{3} + 12 {x}^{2}

The degree of this polynomial is 6.

The coefficient of the leading term is 15

-5x+4y=3<br><br> x=2y-15<br><br><br> Solve for y and x
serious [3.7K]

Answer:

<em><u>x=9, y=12</u></em>

Step-by-step explanation:

-5x+4y=3 --------A

x=2y-15----------B

Putting the value of x from B in A

-5(2y-15) +4y=3

-10y+75+4y=3

-6y=3-72

-6y=-72

y=72/6= 12

Putting the value of y =12 in B

x= 2(12)-15

x= 24-15

x=9
