Answer: b and d
Step-by-step explanation:
Answer:
Sketch the following three graphs:
1) y = (x + 3)²
2) y = -(x + 3)²
3) y = x + 3
First two are parabolas with vertex at (-3,0)
Third one is a line which intersects both the parabolas as (-3,0)
The value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
<h3>System of equation</h3>
For a system of equation to have no solution, the expression on both sides must be different.
Given the system of equation
6x-5y=3 and
3x+ay=1
For the equations to have no solution, the a1/a2= b1/b2
Substitute
6/3 = -5/a
Cross multiply
2 = -5/a
a= -5/2
Hence the value of the constant a will the system of linear equations 6x-5y=3 and 3x+ay=1 have no solution is -5/2
