4. What is the solution of the system of equations?<br> y=-2x+5<br> y=-2x+20
Norma-Jean [14]

The system of equation, y = -2x + 5 and y = -2x + 20, have no solution.

<h3>How to Find the Solution of a System of Equations?</h3>

The solution to a system of equations is the ordered pair of x and y that makes both equations true.

Given the system of equations,

y = -2x + 5 --> equation 1

y = -2x + 20 --> equation 2

Subtract to eliminate variable "y"

0 = 0 + 25

0 = 25 [this is not true]

Therefore, no solution exist for the system of equations.

Thus, we can conclude that, the system of equation, y = -2x + 5 and y = -2x + 20, have no solution.

Solve.<br> x^2+9x+2=0<br> thanks!
shtirl [24]
Step one:
ALWAYS set equation equal to zero, which in this case has already been done for us.

Step two:
Figure out what formula you need to use in order to solve in this case I'd use the Quadratic formula.

a=1
b=9
c=2

Quadratic formula:
x =  \frac{ - b +  -  \sqrt{(b) ^{2}  - 4(a)(c)} }{2(a)}
Then you would plug in the information.
x = \frac{ - 9+  -  \sqrt{(9) {}^{2} - 4(1)(2) } }{2(1)}
The solve for what is underneath the square root ONLY.
x =  \frac{ - 9 +  -  \sqrt{73} }{2}
Since you cannot solve this any further, your final two answers are...
x =   \frac{ - 9 +  \sqrt{73} }{2}
x =   \frac{ - 9 -  \sqrt{73} }{2}
