Solve the system y = -x + 7 and y = 0.5(x - 3)^2
ddd [48]

Answer:

x=-1;\ y=8\\x=5;\ y=2

Step-by-step explanation:

You can make both equations equal and solve for the variable x, as you can see below:

-x+7=0.5(x-3)^2

Keep on mind that:

(a-b)^2=a^2-2ab+b^2

Then:

-x+7=0.5(x-3)^2\\-x+7=0.5(x^2-2(x)(3)+3^2)\\-x+7=0.5x^{2}-3x+4.5\\0=0.5x^2-2x-2.5

Apply the quadratic formula:

x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-2)+/-\sqrt{(-2)^2-4(0.5)(-2.5)}}{2(0.5)}\\x=-1\\x=5

Substitute each value into one of the originl equations to find y, then:

y=-(-1)+7=8\\y=-5+7=2
