Answer:
3.62
Step-by-step explanation:
Let
x = cost of cereal
y = cost of milk
5x + 2y = 31.24
x = $4.80
Substitute into the equation
5x + 2y = 31.24
5(4.80) + 2y = 31.24
24 + 2y = 31.24
2y = 31.24 - 24
2y = 7.24
y = 7.24 / 2
y = $3.62
Therefore,
1 gallon of milk cost $3.62
Answer: Your question is written f(x) = -2*(-3+3)+1. I'll assume you need the answer for just the one value of x (-3)? If so, f(-3) = 1.
Step-by-step explanation:
f(x) = -2*(-3+3)+1
f(x) = -2*(0)+1
f(x) = 1
Other values x for the equation f(x) = -2*(x+3)+1:
-2 is -1
1 is -7
3 is -11

Step-by-step explanation:
Given is perpendicular to then Δ ABC is right
Given =
Then using Pythagoras' identity in the right triangle
² + ² = (5 )² , that is
2 ² = 50 ( divide both sides by 2 )
² = 25 ( take the square root of both sides )
= 5
