Answer:

x=1.666667,−1.666667

Step-by-step explanation:

9x^2−25=0

<u><em>Step 1: Add 25 to both sides.</em></u>

9x^2−25+25=0+25

9x^2=25

<em><u>Step 2: Divide both sides by 9.</u></em>

9x^2/9=259

x^2=25/9

<em><u>Step 3: Take square root.</u></em>

x=±25/9

x=1.666667,−1.666667

slava [35]

Answer:

3

Step-by-step explanation:

-(x-4)+5=3x+6-x(BODMAS)

what is range of the inverse of the relation {(1, 7), (-2, 4), (5, 6), (2, 8)} A. {1, 2,5} B. {-4, 6, 7, 8} C. {1, 5} D. {-4, 7,
Rufina [12.5K]
The answer should be the domain of this relation. {-2, 1, 2, 5} but I do not see that as one of your answer choices.

The inverse of a relation is when you switch the domain and range.  In other words, the domain of the original relation becomes the range of the inverse.

Suppose three lamp posts exist on a straight
Andrews [41]

Answer:

324 ft

Step-by-step explanation:

1. We know there are 3 points (A, B, and C)

so far. We also know B is in the middle of A and C.

A----B----C

2. Reading further, post B is 2x as far from C as it is from A.

A----B----.----C

3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).

A----B----.----C

<- 486ft ->

4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.

A----B----.----C

1 2 3

5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.

A----B----.----C

162 162 162

6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.

7. Make sure to put it into the correct form to answer (ft) and there you go!

Hope I helped! :))
