Find the product .-2 [7 -4 0]
Makovka662 [10]
It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0]                                           solving: [-14 8 0] [-3 0 5]
                                                                           [42+0+70     -24+0+40   0+0+0]  
  [-14 8 0] * [-3 0 5] = [112 0 -30]                           = [112  16  0]
                                                                          [112  16  0]*[6  2  1]
[112 0 -30]* [6 2 1] = [1008 114 0]                  [672+224+112    96+32+16   +0]
                                                                          =[1008  114  0].

Find the solution set <br><br>2x^2 -2x -4 =0<br><br>please use a comma to separate your answer.
mariarad [96]

Answer:

2,-1

Step-by-step explanation:

2x^2 -2x -4 =0

Factor out a 2

2(x^2 -x-2) =0

What 2 number multiply to -2 and add to -1

-2*1 = -2

-2 +1 = -1

2(x-2) (x+1) =0

Using the zero product property

x-2 = 0               x+1 = 0

x-2+2=0+2       x+1-1=0-1

x=2                   x=-1

Please help on two math questions. I don’t understand how to do them.
Sidana [21]

When you represent intervals on the number line, you're including full dots, excluding empty dots, and you're considering numbers highlighted by the line.

In the first case, you've highlighted everything before -2 (full dot, thus included), and everything after 1 (empty dot, excluded). So, the set would be

x\leq -2 \lor\ x>1

or, in interval notation,

(-\infty,-2]\cup (1,\infty)

In the second case, you are looking for all numbers between -3 and 5. This interval is symmetric with respect to 1: you're considering all numbers that are at most 4 units away from 1, both to the left and to the right.

This means that the difference between your numbers at 1 must be at most 4, which is modelled by

|x-1|\leq 4

where the absolute values guarantees that you'll pick numbers to the left and to the right of 1.

How do I do this explain
xeze [42]
So you would take 3x1+2 that gives you 5 and you would keep the same denominator and so that would give you 5/3 then do the same to the other side which would give you 5/4 then you would times it and that would give you 2 1/12
