When you see questions of this nature, test the individual inequalities and look out for their intersection.

For
y < \frac{2}{3} x
Choose a point in the lower or upper half plane created by the line
y = \frac{2}{3} x
The above line is the one which goes through the origin.

Now testing (1,0) yields,

0 < \frac{2}{3} (1)
That is,

0 < \frac{2}{3}
This statement is true. So we shade the lower half of
y = \frac{2}{3} x

For
y \geqslant - x + 2
We test for the origin because, it is not passing through the origin.

0 \geqslant - (0) + 2
This yields
0 \geqslant 2
This statement is false so we shade the upper half.

The intersection is the region shaded in B. The top right graph

Find 5/7 ÷ 3 and how did you find it
Zarrin [17]

Answer:

5/21

Step-by-step explanation:

1. 5/7 divided by 3 is the same as 5/7 divided by 3/1

2. when dividing a fraction, multiply by the reciprocal, so it would be 5/7 times 1/3

3. multiply the numerator and denominators, so 5x1 and 3x7

4. the answer is 5/21
