Mathematics

Answer:

(x - 10)(x - 3)

Step-by-step explanation:

You have to think of numbers that multiply up to 30 and add up to 13. So you eliminate the numbers down to 10 and 3, because you can add up to 13 and multiply to 30. Now you have to find how it adds up to <em>negative </em>13 and multiply it to <em>postive </em>30. 2 negatives make a positive when multiplying, and 2 negatives added together make another negative, so your roots are 10 and 3. Put that into factored form and you have (x - 10)(x - 3).

Alternatively you can either graph to find its zeros or guess-and-check.

antiseptic1488 [7]

Answer:

Using the slope-intercept form, the slope is −35 . The equation of a perpendicular line to y=−3x5+3 y = - 3 x 5 + 3 must have a slope that is the negative reciprocal of the original slope.

Which ordered pair is a solution to this equation?
yarga [219]

Let's test each alternative :

2 x - 9 y = 38      ( 7,5 ) :

( 2 * 7 ) -  ( 9 * 5 ) = 38

14 - 45  = 38

-31 ≠ 38   (  wrong )


( 4 , - 1 ) :

( 2 * 4 ) - ( 9 * ( - 1 ) =  38

8 + 9  = 38

17 ≠ 38  ( wrong )

( 3 , - 3 ) :

2 * ( 3 ) - ( 9 * ( - 3 ) = 38

6 + 27 = 38

33 ≠ 38  ( wrong )

( 1 , - 4 ) :

2* ( 1 ) - 9 * ( - 4 ) = 38

2 + 36 = 38

38 = 38    ( Correct alternative )

( 1 , - 4 ) is correct alternative
