P=12T

Q=66T

-----------

Toys added to each bag:

P=12T+nT

Q=66T+nT

Therefore, 66T+nT=3(12T+nT)

------------

66T+nT=36T+3nT

T(66+n)=T(36+3n)

66+n=36+3n

3n-n=66-36

2n=30

Therefore, n=30/2=15

-------------

*She added 15 toys to each bag.

Solve the following system by graphing. What is the solution?<br> y=-4x-2<br> y=2x+4
Hunter-Best [27]

Answer:

The answer to your question is (-1, 2)

Step-by-step explanation:

Data

       y = -4x - 2                 Equation l

       y = 2x + 4                  Equation ll

Process

-Graph equation l (green line)

 Plot the point (0, -2)

 Starting from this point plot the point (1, -4), this point comes from the slope.

-Graph the equation ll (blue line)

 Plot the point (0, 4)

 Plot the point (1, 2) starting from the previous point.

-The solution is the point where the lines cross. This point is (-1, 2)

What is the area of the triangle?<br>PLSSS help me
AveGali [126]

Answer:

The area of the triangle is A=6 \:units^2.

Step-by-step explanation:

The area <em>A</em> of a triangle is given by the formula A=\frac{1}{2} bh where <em>b</em> is the base and <em>h</em> is the height of the triangle.

From the graph, we can see that the base is 3 units and the height is 4 units. Therefore, the area of the triangle is

A=\frac{1}{2} \cdot3\cdot 4=\frac{12}{2}=6 \:units^2
