What are the prices per cheese stick?
Answer:
y = - x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)
m = = = - , hence
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 9, 6), then
6 = 3 + c ⇒ c = 6 - 3 = 3
y = - x + 3 ← in slope- intercept form
Answer:
Yes
Step-by-step explanation:
The line is pointing up therefore the slope will be positive
Answer:
x=5
Step-by-step explanation:
First combine like terms
8x-8=4x+12
Move -8 over to the other side, it becomes +8
8x=4x+20
Now subtract 4x from 8x
4x=20
Now divide
20÷4=5
x=5
16, 64
8 isn’t a perfect square because no whole number can be multiplied by itself twice to get 8. You can multiply 4 and 4 together and get 16z. You can multiply 8 and 8 together to get 64.
