Answer: Yes they could.

Step-by-step explanation:

The two pairs of sides given are proportional: 3/7 : 9/21

The two triangles have the side:side ratio, meaning they are similar

Lynda cuts a piece of wood for a project. The first cut is shown and can be represented by the equation y=1/4x-5.The secend cut
Svetradugi [14.3K]

Since the second line is parallel to the first, it will have the same slope. The y-intercept of the new line is 4 (because of the coordinates given) so the equation of Lynda's second cut is y = 1/4x + 4 which is choice C

Solve the system y=x²-2 and x²+y=4.Illustrate graphically.
lawyer [7]

Answer:

Solution: (-\sqrt{3},1),(\sqrt{3},1)

Step-by-step explanation:

System of equation:

y=x^2-2\text{ and }x^2+y=4

Using substitution method.

y=x^2-2 substitute into x^2+y=4

x^2+x^2-2=4              (combine like term)

2x^2=4+2                   (Addition property of equality)

2x^2=6                       (division property of equality)

x^2=3                          (Taking square root)

x=\pm \sqrt{3}

Substitute x into  y=x^2-2

y=(\sqrt{3})^2-2

y=1

Solution: (-\sqrt{3},1),(\sqrt{3},1)

Now cross check the solution using graph.

Please find attachment for graph.
