Step-by-step explanation:

Square the lengths of the sides that meet at the right angle. Then add them together and find the square root.

6^{2} = 32\\10^{2} = 100\\\\32 + 100 = 132\\\sqrt{132} = about 12

What is the value of x? Enter your answer in the box.<br><br> x= __
RoseWind [281]

Answer:

x =20

Step-by-step explanation:

We can use similar triangles and proportions to solve.  Take the smaller triangle side on top and the larger triangle side on the bottom.

11                 10

---------- = --------------

11+121             10 +5x+10

Combine like terms

11                 10

---------- = --------------

132             5x+20

Using cross products

11*(5x+20) = 10*132

55x+220 = 1320

Subtract 220 from each side

55x+220-220 = 1320-220

55x = 1100

Divide by 55

55x/55= 1100/55

x =20

Answer for Question 1 is option 2  

Answer for Question 2 is option 3  

Answer for Question 3 is option 3  

Step-by-step explanation:  

For question 1 by plotting the two points we get the coordinates as (-2, 3) and (2, 1) where the x values are -2, 2 and the y values are 3, 1 respectively.  By substituting values of x in the formula given we get that equation 2 satisfies the values of y as in the graph.  

For question 2 the plotted line is split into two parts where one half is for values of x <2 and the other half is for values of x>2. By finding out the coordinates we get them as (2,-2), (1,-2.5) and (0,-3) for x<2 and by substituting the values of x in the formula we get option 3 as our answer.  

For question 3 we need to find the value of y when x=3 and the first condition is only for values greater than 3 so we take the second condition and substitute the value of x=3 and we get the value of y as 5 so the answer is option 3
