Parallel lines will never touch each other while perpendicular forms like an X shape. The slope for the parallel is the same while the perpendicular is a negative reciprocal. (Ex for negative reciprocal. 2/4=4/2)

The Frosty Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On a hot summer day, the shop sold 8 more sundaes than
sineoko [7]

Answer:

The number of sundaes sold are 36.

Step-by-step explanation:

<em>The cost of each sundae is $2 and the cost of each banana splits is $3.</em>

<em>The number of sundae sold be "x" and banana split be "y".</em>

Thus, the total amount spent is,

= 2x+3y

The total amount spent is given to be $156. Thus,

156 = 2x+3y

It is also given that, the shop sold 8 more sundaes than banana splits. In equation form,

x = y+8

y = x-8,

Inserting this value of y in above equation, we get,

156 = 2x+3(x-8) =  5x-24

180 = 5x

Thus, x = 36 = number of sundae sold.

Rama09 [41]

Hello,


if y≠0 then


ay^2-[-5y-y(-7y-9)]-[-y(15y+4)]=0\\\\ay^2-[-5y+7y^2+9y]-[-15y^2-4y]=0\\\\ay^2+5y-7y^2-9y+15y^2+4y=0\\\\ay^2+8y^2=0\\\\(a+8)y^2=0\\\\a=-8\\\\\\
