The answer for this question would be x + 7y > 3. You can figure this out because it is GREATER THAN. If it was greater than or equal to then the line would be solid (same with less than or equal to).

Urgent please help .On a piece of graph paper, graph y+2<-2/3x+4

Serjik [45]

Take a look at the function $y+2=- \frac{2}{3}x+4$ . You can simplify it to $y=- \frac{2}{3}x+2$ . If x=0, then y=2 and when y=0, x=3. You obtain two points (0,2) and (3,0) that lie on the line $y+2=- \frac{2}{3}x+4$ .

Since $y+2\le - \frac{2}{3}x+4$ , the line $y+2=- \frac{2}{3}x+4$ should belong to the shaded area.

Now take point (0,0). Since $0+2\le- \frac{2}{3}\cdot 0+4$ , you can conclude that point (0,0) belongs to the shaded area.Using all these thoughts, you can make a conclusion that the correct choice is B.

The circumference of a circular design is 2020 inches.

zhuklara [117]

Answer:

Diameter of the circle is twice it's radius D=2r.

Circumference of the circle is 2πr.

According to the above problem,

2π(radius)=20 inches

2(radius)=20/π=20/3.14

Diameter=6.37 inches

<h3>6.37 inches is the right answer.</h3>
