R; all quadratic functions are going to have *ALL REAL NUMBERS*.
Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
x and 65° are a linear pair and sum to 180°
x + 65° = 180° ( subtract 65° from both sides )
x = 115°
y and 65° are vertically opposite angles and are congruent , then
y = 65°
x and z are vertically opposite angles and are congruent , then
z = x = 115°
Answer:
1/3 part of 120 hours....
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 4)² + (y - 1)² = 34 ← is in standard form
with centre = (4, 1 ) and r² = 34 ⇒ r = → A
19+(-19)=0
Step-by-step explanation:
So first lets simplify this. We can use the method keep,change, change to do this. Keep the value of positive 19. Then change the + sign to - and the - sign to plus which gets us
19-(+19).
We can remove the +since we know its positive leaving 19-19 which is 0
