Answer:

Step-by-step explanation:

The area of a triangle is base $b$ times height $h$ divided by $2$ . You can use the first triangle to solve for the height: $9\cdot h/2=27$ means that $h=6$ . The larger triangle is proportional to the smaller one. In fact, it is $1.\bar3$ times larger. This means that the height of the larger triangle is $6\cdot1.\bar3=8$ . Putting all of this together, you can then calculate the area: $12\cdot8/2=48$ .

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.
