Infinitely many solutions

Step-by-step explanation:

2y=14-2x

y=-x+7

Solving quadratic equations with complex solutions x2 + 4x + 8 = 0.
Daniel [21]

Answer:

\large\boxed{x=-2\pm2i}

Step-by-step explanation:

x^2+4x+8=0\qquad\text{subtract 8 from both sides}\\\\x^2+4x+8-8=0-8\\\\x^2+2(x)(2)=-8\qquad\text{add}\ 2^2\ \text{to both sides}\\\\x^2+2(x)(2)+2^2=-8+2^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+2)^2=-8+4\\\\(x+2)^2=-4\iff x+2=\pm\sqrt{-4}\\\\x+2=\pm\sqrt{(4)(-1)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\x+2=\pm\sqrt4\cdot\sqrt{-1}\qquad\text{use}\ \sqrt{-1}=i\\\\x+2=\pm2\cdot i\qquad\text{subtract 2 from both sides}\\\\x=-2\pm2i

At Centertown Middle School, 25% of the 124 students Mrs. Wade teaches buy their lunches in the cafeteria.
cluponka [151]

Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.

<u>Step-by-step explanation:</u>

It is given that,

The 25% of 124 students are taught to buy their lunches in cafeteria.

Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.

<u>To find the number of students who are capable to buy lunches in cafeteria:</u>

  • Replace the % symbol into the numeric form.
  • The % is represented by 1 ÷ 100.

The 25% of 124 students is written as,

⇒ 25×(1/100)×124

⇒ (1/4)×124

⇒ 31

The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
