Factoring trinomials, mind helping me out?

Answer:

(x - 13)(x + 3)

Step-by-step explanation:

The square term is just x^2 with no coefficient.

Write:

(x    )(x    )

Now you need two numbers that multiply to -39 and add to -10.

39 = 3 * 13

The numbers you need are -13 and 3 since -13 * 3 = -39, and -13 + 3 = -10.

Now write the numbers -13 and +3 in the parentheses.

(x - 13)(x + 3)

Answer: (x+3)(x-13)

Step-by-step explanation:

write -10x as a difference to get

x^2+3x-13x-39

factor out x from the espression

x+(x+3)

factor out -13 from the expression

-13(x+3)

factor out x+3 from the expression

(x+3)(x-13)

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>
