Solve the following system of equations and show all work. y = −x2 + 4 y = 2x + 1

Aneli [31]

Answer:

x=3/4,y=5/2

Step-by-step explanation:

y=-x^2+4,y=2x+1

substitute y=-x^2+4 as y for y=2x+1

2x+1=-x^2+4, x=3/4(isolate "x")

x=3/4

substitute x=3/4 for 2x+1=-x^2+4

y=2*3/4+1

y=5/2

x=3/4, y=5/2

hope this helps!

$\bf \begin{array}{llccll}
y=&1x^2&-6x&+9\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad discriminant\implies b^2-4ac$

so... what does that give you for the discriminant?

if it's a negative value, no solutions
if it's a positive value, two solutions
if it's 0, one solution
