felix is a car mechanic. he can fix 2 motorcycles and 3 cars in 170 minutes. he can fix 1 motorcycle and 5 cars in 225 minutes.
vekshin1

Answer:

2x+3y=170.......1

1x+5y=225.......2

multiplying equation 2 by 2 and subtracting eq.1 &2

2x+3y-2x-10x=170-225

-7x=-55

x=55/7

55/7+5y=225

5y=225-55/7

y=1520/(7×5)=304/7

I got a maths equation which i don't really get how to work out, the question is : solve 4x^2+x-3=0
Maru [420]

The solutions for the given equation 4x^2+x-3=0 are x = -1 and x = 3/4. Using the quadratic formula, the solutions for the given equation are calculated.

<h3>What is the quadratic formula?</h3>

The formula which is used to calculate the roots(solutions) of the quadratic equation in the form ax^2+bx+c=0 is

x = [- b ± \sqrt{b^2-4ac}]/2a

<h3>Calculation:</h3>

The given equation is 4x^2+x-3=0

In comparison with the standard form of quadratic equation ax^2+bx+c=0,

we get, a = 4, b = 1 and c = -3

So, solving the given equation using the quadratic formula,

x = [- b ± \sqrt{b^2-4ac}]/2a

  = [- 1 ± \sqrt{1-4(4)(-3)}]/2(4)

  = [-1 ± \sqrt{49}]/8

  = (-1 ± 7)/8

Thus, x =  (-1 + 7)/8 = 3/4 and x = (-1-7)/8 = -8/8 = -1

Therefore, the solutions of the given equation are x = -1 and x = 3/4.
