Step-by-step explanation:
Let U=universal set
C=students who drink coke
P = students who drink pepsi
<u>P = 2L + 2W</u>
Subtract 2L from each side: P - 2L = 2W
Divide each side by 2 : <em>(P - 2L) / 2 = W </em>
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
So multiply both sides by 5x to make 4/5x a whole number. So you get 4+5<-15x. So then simplifying you add 4 and 5. You get 9<-15x. So now divide both sides by -15 and switch the < to > because you’re multiplying by a negative. So then you get x<-9/15
