8x2 + 15x + 7 = 0 factors to
(8x + 7) (x + 1) = 0
Therefore the 2 linear equations are:
1. 8x + 7 = 0
Thus 8x = -7
x = -0.875
and
2. x + 1 = 0
Thus x = -1
Inconsistent linear equations in two variables.
When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
Two equations: a linear one in y and a quadratic in x.
Yes, because neither variable has an exponent different from ' 1 '.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.

a=5: c=4
One option is "cannot exist". The equation is linear and linear equations do not have vertices.
Yes, because neither variable has an exponent different from ' 1 '.
A "system of equations" implies that there is more than one equation.
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
It's one of the simplest linear equations in 'x' that can be written. Its solution is [ x = -5 ].
It is perpendicular to a family of other linear equations: of the form 4y = x + c
y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
It is a single equation of direct proportionality. It cannot be solved since that would require two linear equations.
