3: subtraction
4: division
5: subtraction
6: division (I think)
7: addition
8: subtraction
9: multiplication
10: addition
12: n/10
13: n+6
14: 9x(n-5)
15: 4n-1
16: 50+40h
Step-by-step explanation:
you said its easy so i assume you know how to do it
1st angle = 3x
2nd angle = x
3rd angle = 65 +x
3x + x +65+x = 180
5x+65 = 180
5x=115
x = 115/5 = 23
2nd angle = 23 degrees
1st angle = 23 x 3 = 69 degrees
3rd angle = 65 +23 = 88 degrees
Answer:
x=1 and y=−1
Step-by-step explanation:
Use substitution in order to solve this.
Answer:
<em>d) The equation of the standard parabola</em>
<em> x² = 6 y</em>
Step-by-step explanation:
The given directrix is y= -31.5
The equation of the parabola is of the form x² =4 a y
Given focus (0,1.5) , Here a= 1.5
The equation of the standard parabola
x² = 4 a y
x² = 4 (1.5)y
x² = 6 y
<u><em>Conclusion</em></u>:-
<em>The equation of the standard parabola</em>
<em> x² = 6 y</em>
