Answer:  The required equation of the line is y=-\dfrac{5}{2}x-1.

Step-by-step explanation:  We are given to find the equation of the line that is parallel to the following line and passes through the point (-2, 4) :

5x+2y=12~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

the slope-intercept form of the equation of a straight line is given by

y=mx+c,

where m is the slope of the line.

From equation (i), we have

5x+2y=12\\\\\Rightarrow 2y=-5x+12\\\\\Rightarrow y=-\dfrac{5}{2}x+6.

So, the slope of line (i) is given by

m=-\dfrac{5}{2}.

We know that the slopes of two parallel lines are equal. So, the slope of the new line will be

m=-\dfrac{5}{2}.

Since the line passes through the point (-2, 4), so its equation will be

y-4=m(x-(-2))\\\\\\\Rightarrow  y-4=-\dfrac{5}{2}(x+2)\\\\\\\Rightarrow y-4=-\dfrac{5}{2}x-5+4\\\\\\\Rightarrow y=-\dfrac{5}{2}x-1.

Thus, the required equation of the line is y=-\dfrac{5}{2}x-1.

Solve x2 – 7x = –13.
aleksklad [387]

we have

x^{2} -7x=-13

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2} -7x+3.5^{2}=-13+3.5^{2}

x^{2} -7x+12.25=-13+12.25

x^{2} -7x+12.25=-0.75

Rewrite as perfect squares

(x-3.5)^{2}=-0.75

remember that

i=\sqrt{-1}

Square root both sides

(x-3.5)=(+/-)\sqrt{-0.75}

(x-3.5)=(+/-)\sqrt{-1*0.75}

(x-3.5)=(+/-)\sqrt{0.75}i

x1=3.5+\sqrt{0.75}i

x2=3.5-\sqrt{0.75}i

Simplify

\sqrt{0.75}=\frac{\sqrt{3}}{2}

x1=3.5+\frac{\sqrt{3}}{2}i

x2=3.5-\frac{\sqrt{3}}{2}i

therefore

<u>the answer is</u>

x1=3.5+\frac{\sqrt{3}}{2}i

x2=3.5-\frac{\sqrt{3}}{2}i
