Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that
5 packs of chicken and 6 packs of beef for $94.25.
This means that
We have to solve the following system:
I will use the addition method, multiplying the first equation by -2, and adding to the second
-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And
Each pack of chicken costs $8 and each pack of beef costs $9.24.
A leg of a right triangle can never be greater then the hypotenuse
this formula will tell you if it's a valid right triangle
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.
THE STEPS:
ANSWER:
A
to calculate the slope m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, - 2 ) and (x₂, y₂ ) = (- 1, - 5 )
m = = = → A
