Sam has $400 in his bank account and plans to save $25 per week. Zoe has $250 in her bank account and plans to save $75 per week

Say x is the number of weeks until their money is equal. Then, we can set up an equation.

400 + 25x = 250 + 75x

Subtract 250 from both sides

150 + 25x = 75x

Subtract 25x from both sides

150 = 50x

Divide by 50 on both sides

3 = x

That means the answer is 3 weeks.

Use the Quadratic Formula to find the exact solutions of x2 + 7x - 4 = 0.

Answer:

The solution of equation $x^2+7x-4=0$ is 0.53,-7.53.

Step-by-step explanation:

Given : Quadratic equation $x^2+7x-4=0$

To find : The solution of equation ?

Solution :

The solution of the quadratic equation $ax^2+bx+c=0$ is $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, a=1, b=7 and c=-4.

Substitute the values,

$x=\frac{-7\pm\sqrt{7^2-4(1)(-4)}}{2(1)}$

$x=\frac{-7\pm\sqrt{65}}{2}$

$x=\frac{-7+\sqrt{65}}{2},\frac{-7-\sqrt{65}}{2}$

$x=0.53,-7.53$

Therefore, the solution of equation $x^2+7x-4=0$ is 0.53,-7.53.
