Solve the simultaneous equation y-2x+1=0 and 4x^2+3y^2-2xy=7

Lapatulllka [165]

The first equation is $y-2x+1=0$

$y=2x-1$ (Equation 1)

The second equation is $4x^{2}+3y^{2}-2xy=7$ (Equation 2)

Putting the value of x from equation 1 in equation 2.

we get,

$4x^{2}+3(2x-1)^{2}-2x(2x-1)=7$

$4x^{2}+3(4x^{2}+1-4x)-4x^{2}+2x=7$

by simplifying the given equation,

$12x^{2}-10x-4=0$

$6x^{2}-5x-2=0$

Using discriminant formula,

$D=b^{2}-4ac$

$D=25-4 \times 6 \times -2 = 73$

Now the formula for solution 'x' of quadratic equation is given by:

$x=\frac{-b+\sqrt{D}}{2a} and x=\frac{-b-\sqrt{D}}{2a}$

$x=\frac{5+\sqrt{73}}{12} and x=\frac{5-\sqrt{73}}{12}$

Hence, these are the required solutions.

Find the value of r so the line passes through each pair of points has the give slopes

Art [367]

Answer:

$r=64$

Step-by-step explanation:

First, let's start with what we have. If we use $y=mx+b$ here's what we can put in:

$y=-4x+b$

Then we can use one of the given points to find the y-intercept. Since the only complete one is (12,10), we'll use that.

$10=-4(12)+b\\10=-48+b\\58=b$

So now we have $y=-4x+58$ .

Now we can use our other point with the missing y-value and solve for y.

$r=-4(-2)+58\\r=64$

So the missing value is 64.

Hope this helps!
