Which values for x and y make the statement (x + 5)(y - 6) = 0 true?

Mathematics

-BARSIC- [3]3 years ago
6 0
<span>                             ||Solving \ for \ x. ||  </span>

(x + 5)(y - 6) = 0 

(x + 5)(y - 6) = 0 :x

&#10;x+5=0&#10; &#10;  |Divide \ both \ sides \ by \ y-6| 

&#10;x=-5&#10; &#10;  |Subtract \ 5 \ from \ both \ sides|

                           ||Solving \ for \ y. || 

&#10;y-6=0&#10; &#10;  |Divide \ both \ sides \ by \ x+5| 
 
&#10;y=6&#10; &#10; 

Solution =\ \textgreater \ x = -5, y = 6

Find the value of x.
nadezda [96]

Answer:

25

Step-by-step explanation:

The median of a trapezoid equals one half of the sum of the bases

AC is a median and EB and DF are the bases.

hence AC = 1/2(EB + DF)

We are given that EB = 13 and that AC = 19. And we need to find DF

To do so we plug in what we are given and solve for DF

AC = 1/2(EB + DF)

AC = 19, EB = 13

19 = 1/2(13 + DF)

Now solve for DF

* Multiply both sides by 2*

19 * 2 = 38

1/2(13 + DF) * 2 ( the 1/2 and 2 cancel out and we're left with 13 + DF )

We then have 38 = 13 + DF

* Subtract 13 from both sides *

38 - 13 = 13 - 13 + DF

We get that DF = 25

I need help with this:What is the value of y? Enter your answer in the box. y =
lina2011 [118]

Answer:

y=5 degrees

Step-by-step explanation:

It is an isosceles triangle so that means that there are two angles that equal 75, so that means the third side with 4y + 10 is equal to 30 degrees.

4y+10=30

4y=20

y=5 degrees

Which value for x completes the conditional relative frequency table by column? 0.17 0.25 0.40 0.85
Alchen [17]

The value of x that completes the conditional relative frequency table by column is 0.85

<h3>How to determine the value of x?</h3>

From the complete question, we have the following column elements

0.15   x     1

Express a sum

0.15 + x = 1

Subtract 0.15 from both sides

x = 0.85

Hence, the value of x that completes the conditional relative frequency table by column is 0.85
