Josiah and his children went into a bakery where they sell cupcakes for $4.50 each and cookies for $1.25 each. Josiah has $45 to spend and must buy a minimum of 12 cupcakes and cookies altogether. Also, he must buy a minimum of 20 cookies. If xx represents the number of cupcakes purchased and yy represents the number of cookies purchased, write and solve a system of inequalities graphically and determine one possible solution.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

i cant answer this, theres no table. sorry man

step-by-step explanation:

b

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
