The diagram shows two straight lines. Both lines intersect at point A. У y = 4x A х A y = -2 Identify the coordinates of point A

Semmy [17]

Answer:

Point $A$ is at $(-1/2,\, -2)$ .

Step-by-step explanation:

The intersection $(x,\, y)$ of two lines in a plane could be found by solving a linear system of two unknowns ( $x$ and $y$ ) and two equations (one for each line.)

In this question, the equation of the two lines are $y = 4\, x$ and $y = -2$ , respectively. The corresponding system of equations would be:

$\left\lbrace \begin{aligned} & y = 4\, x \\ & y = -2\end{aligned} \right.$ .

Solve this system for $x$ and $y$ :

$y = (-2)$ .
Substitute $y = (-2)$ into the first equation and solve for $x\!$ : $x = (-1/2)$ .

Therefore:

$\left\lbrace \begin{aligned} & x = -\frac{1}{2} \\ & y = -2\end{aligned} \right.$ .

Thus, the coordinates of this intersection $(x,\, y)$ would be $(-1/2,\, -2)$ .

Sylvia had a small box. She filled it with 64 triangle pattern blocks. She said "The volume of this box is 64 cubic units." Do y

Advocard [28]

Answer:

I do not agree with Sylvia

Step-by-step explanation:

Given

1 small box

64 triangle pattern blocks

Required

Is she right?

From the question, we understand that she fills the box with 64 blocks.

For the fact that she did this; it does not mean that the volume of the small box is 64 cubic units (even if she filled the box completely and the triangle pattern blocks are identical)

The reason for this is that, the volume of each box may not be 1 cubic unit.

So, first she needs to determine the volume of each pattern block, then multiply by 64. If the result is 64, then the volume of the box is 64 cubic units.

Since, it is not stated, we will not make any assumptions.

Hence, I do not agree with Sylvia.
