1 answer:
miss Akunina [59]2 years ago
5 0

\\ \tt\longmapsto y=\sqrt{-x^2+px+q}

  • Put(3,10)

\\ \tt\longmapsto y^2=-x^2+px+q

\\ \tt\longmapsto 10^2=-(3^)2+3p+q

\\ \tt\longmapsto 100=-9+3p+q

\\ \tt\longmapsto 3p+q=109

  • Use hit and trial method.

Let p,q be (27,28)

Apply

\\ \tt\longmapsto 3(27)+28=81+28=109

Twice the difference of x and 5 is -33
Elden [556K]
2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.

Find the slope and the y-intercept of the line <br> Y=-5/4x+8
insens350 [35]

Explanation: This is a linear equation because it's written in slope-intercept form or <em>y = mx + b</em> where the multiplier or the coefficient of the x-term represents the slope of the line and the<em> b</em> represents the constant term.

So the slope will be the coefficient of the <em>x-term</em> which means the number that is in front of the <em>x</em> which in this case is -5/4.

The y-intercept is the constant term which is +8
