5y = 2x - 7
y = 2/5x - 7/5
Slope = -5/2 (perpendicular)
Slope int. = y = mx + b
Y = -5/2x + b
-3 = -5/2(2) + b
-3 = -5 + b, b = 2
Solution: y = -5/2x + 2

Help me please!! This is timed and I’m stuck
zhuklara [117]

Let's solve

\\ \sf\longmapsto 2x^2+7x-15=0

\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{7^2-4(2)(-15)}}{2(2)}

\\ \sf\longmapsto x=\dfrac{-7\pm\sqrt{169}}{4}

\\ \sf\longmapsto x=\dfrac{-7\pm13}{4}

\\ \sf\longmapsto x=\dfrac{-7+13}{4}\:or \:\dfrac{-7-13}{4}

\\ \sf\longmapsto x=\dfrac{6}{4}\:or\:\dfrac{-20}{4}

\\ \sf\longmapsto x=\dfrac{3}{2}\:or -5

Subtract

\\ \sf\longmapsto 3/2-(-5)=3/2+5=13/2

Cos17=73/y please tell me what y equals
dusya [7]
If you are doing division, you should be able to turn the equation around as a fact family, making it multiplication. All you need to do is 17x73=y.
y=1241
