We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:
-2x + y = 1
y = 1 + 2x
4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3
y= 1 + 2(-1/3)
y = 1/3
Answer:
The function of this equation is: ![F(n)=\frac{1}{4}n^4-\frac{1}{3}n^3+n+C](https://tex.z-dn.net/?f=F%28n%29%3D%5Cfrac%7B1%7D%7B4%7Dn%5E4-%5Cfrac%7B1%7D%7B3%7Dn%5E3%2Bn%2BC)
Step-by-step explanation:
I think 70 because playing on a varsity, i think, means to play both sports. So I added 10 to the number of students that play basket ball, which is also equal to the number of students that like tennis.
im not sure
A). 12 ÷ $7.20 = about $1.67 per muffin
b). 8 ÷ $4.40 = about $1.81 per muffin
c). 6 ÷ $4.50 = about $1.33 per muffin
type C costs the least per muffin
It’s an isosceles triangle so it’s 4
