Because 1/2 and 1/4 are equal amounts, if that makes sense
Answer:
Linear graphs display as a straight line when plotted, hence the name linear
Step-by-step explanation:
Vertex: V=(-2,-3)=(h,k)→h=-2, k=-3
The parabola is horizontal, then its equation has the form:
x=a(y-k)^2+h
x=a(y-(-3))^2+(-2)
x=a(y+3)^2-2
When the y-value is -2, the x-value is -5:
-5=a(-2+3)^2-2
-5=a(1)^2-2
-5=a(1)-2
-5=a-2
-5+2=a-2+2
-3=a
a=-3
Answer: The coefficient of the squared term in the parabola's equation is a=-3
Answer: Option D. -3
Answer:
X= 8
Y= 130
(8, 130)

Complete Question
A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20
Answer:
$7
Step-by-step explanation:
From the question we are told that :
Any 4 entrees = $20,
And there is a discount of $2 per entree.
Let us represent the original average cost of entrees as = a
Hence, we have the algebraic expression
4(a - 2) = 20
4a - 8 = 20
4a = 20 + 8
4a = 28
Divide both sides by 4
4a/4 = 28/4
a = 7
Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.
