Answer:
Rectangular Cuboid
Step-by-step explanation:
A rectangular cuboid has 4 faces that are rectangles and 2 faces that are squares. Since a square is a rectangle, this shape is technically built of 6 rectangles and is creates a 3-dimensional shape. Hence, we have the prism, rectangular cuboid.
Given the function, f(x) = 8x + 7:
Since it is a linear function, it doesn’t have any constraints or undefined points. Thus, the <em><u>domain</u></em> is all real numbers as x-values.
Domain: interval notation: (-∞, ∞)
Set notation: {x | x ∈ R}
The same goes for the <u><em>range</em></u>: all real numbers are valid as outputs (y-values).
Range: interval notation: (-∞, ∞)
Set notation: {y | y ∈ R}

Marcario should use 4 pounds of macadamia nuts and 8 pounds of almonds.
Explanation
given
cost of macadamia nuts per pound=$9
cost of almond nuts per pound=$5.25
cost of the mixture per pound=$6.5
total pounds of the mixture to be made=12
let the pounds of macadamia nuts=x
pounds of almond nuts=y
total pounds of nuts=x+y=12
solving (1) and (2)
x=4
y=8
Match the points up with the given equation to find your answer
