In the figure, AOB and COD are straight lines. Find x and y.<br> E<br> A<br> 20<br> 65<br> B
ASHA 777 [7]

The image of the straight lines is missing so i have attached it.

Answer:

x = 20°

y = 120°

Step-by-step explanation:

From the image attached, we can say that;

3x + (7x - 20) = 180

This is because sum of angles on a straight line is 180°

Thus;

3x + 7x - 20 = 180

10x = 180 + 20

10x = 200

x = 200/10

x = 20°

Also,3x + y = 180

Because sum of angles on a straight line is 180°. Thus;

3(20) + y = 180

60 + y = 180

y = 180 - 60

y = 120°

Which graph represents the piecewise-defined function?
kifflom [539]

Answer: The first option is correct.

Explanation:

The given piecewise function is,

y=\begin{cases}-\frac{4}{5}x-3 & \text{ if } x

From the piecewise function we can say that if x<0, then

f(x)=-\frac{4}{5}x-3

If x\geq2, then

f(x)=3x-10

Since the f(x) is defined for x<0 and x\geq2, therefore the function f(x) is not defined for 0\leq x.

In the graph 2, 3 and 4 for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.

Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for 0\leq x, hence the first option is correct.
