Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
Its choice A
Answer:
y=x^2
Step-by-step explanation:
Answer:
π radians
Step-by-step explanation:
The angle subtended at the centre by an arc, has the same measure as the arc subtending it, then
angle subtended = measure of arc = π radians
