Answer:
a = 2, b = 1 and c = 10
Step-by-step explanation:
The given equation is 2x² + x + 10 = 0 ...(1)
The general form of a quadratic equation is given by :
ax²+bx+c=0 ...(2)
We need to find the values of a,b and c in the given equation.
Comparing equation (1) and (2),
a = 2, b = 1 and c = 10
Answer:
The found values are:
A = 1/3
B = -8/3
Step-by-step explanation:
We know that general equation is given by:
y = mx + c
where m is the slope and c is a constant.
x + 3y = -5
y = -(1/3)x - 1/3(5)
Slop of the equation is -(1/3). As parallel line have same slope substitute it in the first equation:
Ax + By = 3
By = -Ax - 3
By = (1/3)x - 3
Hence, A = 1/3
Substitute point (-7,2) into the equation:
B(2) = (1/3)(-7) -3
B(2) = -7/3 - 3
B(2) = -16/3
B = -16/6
B = -8/3
Answer:
yes
Step-by-step explanation:
on a graph, if you need it to be proportional, it has to start at (0,0)
if you need it to not be proportional, it can start anywhere except (0,0)
