3x+17=2x-6
-2x -2x * subtract 2x from both sides* *3x-2x is 1x*
1x+17=-6 *now subtract 17 from both sides*
-17 -17
1x=-23
1x. 1x
x=23

What does "Classify the polynomial by the number of terms" mean
soldier1979 [14.2K]

"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like 2x^{2}.

A binomial has 2 terms like 3x^{2}+6x

A trinomial has 3 terms like 4x^{2}+5x-8

And a polynomial has 4 or more terms.

So basically one can classify the type of polynomial by counting the number of terms in a given equation.

1,write the successor of-5 and predecessor of 6 then add them
Alona [7]

#1

  • Successor of -5=-4
  • Predecessor of 6=5

\\ \tt\hookrightarrow -4+5=1

#2

  • Let one be x and other be x-1

\\ \tt\hookrightarrow a-b=x-x+1=+1

#3

\\ \tt\hookrightarrow 42-66-(100-24)

\\ \tt\hookrightarrow -24-76

\\ \tt\hookrightarrow -100

Which graph correctly represents 1/3y-1/2x>2 ?
Tanzania [10]
<span>Put it in the form of y =mx +b, or in this instance, y> mx +b 
move the (1/2) x to the right by adding it to both sides of the inequality 
(1/3)y>(1/2)x +2 
Multiply by 3 on both sides to get y by itself. 
y>(3/2) x +6 
This is a graph with y intercept of (0,6) and a moderate upward and to the right slope. Because it is > , the line on the graph will NOT be part of the solution. 

The easiest way to find the side of the graph that the inequality satisfies is to use (0,0) and see if it works or doesn't work. In the original equation, 0-0>2 does NOT work, so the area where the inequality works is to the up and left of the graph, which should be a dotted line to show that the inequality is greater than only. 
The point (6,-2) should work.
Test it. 6*(1/3)-(-2)*(1/2)>0 ; 2-(-1)=3, and 3>2 It does work. 
The point (6,2) should not work 
Test it. 6 *(1/3)-2(1/2)=2-1 ; 1 is NOT >2, so it does not work. 
If the graph goes through the origin, then pick a point near the graph with a small x or y.</span>
