Hurryy i am begging for ive been stuck for an hour
sarah has $8 and wants to buy a combination of cupcakes and fudge to feed at least four siblings. each cupcake costs $2, and each piece of fudge costs $1. this system of inequalities models the scenario:

2x + y ≤ 8
x + y ≥ 4

part a: describe the graph of the system of inequalities, including shading and the types of lines graphed. provide a description of the solution set. (4 points)

part b: is the point (8, 10) included in the solution area for the system? justify your answer mathematically. (3 points)

part c: choose a point in the solution set and interpret what it means in terms of the real-world context. (3 points)

Step-by-step explanation:

(1,2)(2,7)

slope = (7 - 2) / (2 - 1) = 5/1 or just 5

y = mx + b

slope(m) = 5

use either of ur points (1,2)...x = 1 and y = 2

now we sub and find b, the y int

2 = 5(1) + b

2 = 5 + b

2 - 5 = b

-3 = b

so ur equation is : y = 5x + (-3)...or it can also be written as : y = 5x - 3

(1,2)(2,7)

slope = (7 - 2) / (2 - 1) = 5/1 or just 5

y = mx + b

slope(m) = 5

use either of ur points (1,2)...x = 1 and y = 2

now we sub and find b, the y int

2 = 5(1) + b

2 = 5 + b

2 - 5 = b

-3 = b

so ur equation is : y = 5x + (-3)...or it can also be written as : y = 5x - 3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

irrational, cannot
