Answer:
The correct equation is D.) 6x - 7y = -11
Step-by-step explanation:
<u>Jessica has 5 cupcake cases left.</u>
<em>First, divide 50 into groups of five. Next, subtract two groups of five from 50. Third, divide the remaining cases into groups of six. Finally, subtract 5 groups of six from the remains from the last subtraction equation. </em>
Step-by-step explanation:
6 (x+5 )^2 +5(x+5)-4=0
let x+5= y
6y^2 + 5y - 4=0
6y^2 + 8y - 3y-4 =0
2y (3y+4) - 1 (3y+4)=0
(2y-1)(3y+4)=0
2y-1=0 or 3y+4=0
y=1/3 or -4/3
Recall that x+5=y
When y=1/3
x+5=1/3
x= -14/3
when y= -4/3
x+5=-4/3
x = -11/3
