Please help me, it’s a math question

Mathematics
1 answer:
Mandarinka [93]3 years ago
4 0

Answer:

Step-by-step explanation:

Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.

It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.

The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.

Plz help me with this . its says determine if it's linear or not linear .explain ur decisison.​
sergey [27]

Answer:

I say that d) is linear because I found the common difference of +2 in the y which makes the line of a graph straight.

And c) is non linear because there is no sequence so if you create a line out of this table, the line of a graph will not be straight.
