Answer: The answer is zero/0 That is because an opposite of a positive integer would be a negative.
An example is-
3 >>> its opposite is -3,
3 + -3 = 0
(−1, −2) and (3, 10).
y +__ = __(x + 1)
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
C. 50
Step-by-step explanation:
We are given ΔABC with an altitude BD as shown in the figure.
As it is known that,
'When an altitude is drawn from a right angle of a triangle, then all the three triangles are congruent.'
So, we get that ΔABC ≅ ΔABD ≅ CBD.
Since, the triangles are congruent, their corresponding sides and angles will be congruent.
Moreover, the ratio of the sides will be equal.
So, we get from ΔABC ≅ ΔABD,
i.e.
i.e.
i.e.
i.e.
i.e. z = 50.
Hence, the value of z is 50.
