BabaBlast [244]

Answer:

x=7, x=3

Step-by-step explanation:

$x^{2} -8x+14=2x-7$

$x^{2} -8x-2x+14+7=0$

$x^{2} -10x+21=0$

$\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}$

$x=$ $\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

positive

$x=\frac{-\left(-10\right)+\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}$

$x=7$

negative

$x=\frac{-\left(-10\right)-\sqrt{\left(-10\right)^2-4\cdot \:1\cdot \:21}}{2\cdot \:1}$

$x=3$

Write an equation for the line described. Give the answer in standard form. through (2,6), m= -5

LiRa [457]

9514 1404 393

Answer:

5x +y = 16

Step-by-step explanation:

Given a point and slope, it often works well to start with the point-slope form of the equation for a line:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Your point and slope make this ...

y -6 = -5(x -2)

y -6 = -5x +10 . . . . . . eliminate parentheses

5x +y = 16 . . . . . . . . . add 5x+6 to both sides; your standard form equation
