The answer is -1 , because when you add a negative number to a positive number the negative number will subtract , and vise versa.
A rational number<span> is a </span>number<span> that </span>can be written<span> as a </span>ratio<span>. That means it </span>can be written<span> as a fraction, in which both the numerator (the </span>number<span> on top) and the denominator (the </span>number<span> on the bottom) are whole </span>numbers<span>. The </span>number<span> 8 is </span>a rational number<span> because it </span>can be written<span> as the fraction 8/</span>1<span>.</span>
Answer:
Option (A)
Step-by-step explanation:
By applying the theorem angle theorem in the given triangle,
Sum of exterior angle of a triangle is equal to the sum of opposite interior angles of the triangle.
Therefore, 130° = y° + y°
130° = 2y°
y = 
y = 65°
Therefore, measure of interior angles 'y' of the given triangle will be 65°.
Option (A) will be the answer.
Answer:
x = - 
Step-by-step explanation:
Given a quadratic equation in standard form , that is
y = ax² + bx + c = 0 ; a ≠ 0
Then the x- coordinate of the vertex is
= - 
x² + bx + c = 0 ← is in standard form
with a = 1, b = b, thus
= -
