Answer:
5y - 2x = 0
Step-by-step explanation:
Equation of line is given by,
y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )
y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )
y = 2x /5
5y = 2x
5y - 2x = 0
This is the required equation.
Answer:
129
Step-by-step explanation:
278 - 149 = 129
Answer:
68.
Step-by-step explanation:
The common difference d = -19 - (-22) = 3
So the 31st term =
a31 = -22 + (31-1)3
= -22 + 90
= 90 - 22
= 68.
Answer:
see below
Step-by-step explanation:
The graph opens upward if the sign of the squared term is positive. If that sign is negative, the graph opens downward. The first three equations open upward; the last opens downward.
The line of symmetry is the value of x that makes the squared term zero. Here, that is x=5 for all equations.
<u>y=2/3(x-5)^2</u>: A, D
<u>y=1/2(x-5)^2</u>: A, D
<u>y=3/4(x-5)^2</u>: A, D
<u>y=-4(x-5)^2</u>: B, D
