If Lakita buys x boxes of water bottles, she will have y = 16x + 69 water bottles.

<span> Lakita has enough money to buy only up to 5 boxes of water bottles, so she can buy 0, 1, 2, 3, 4, or 5 boxes of water bottles. These are the only reasonable values for the domain. Substitute these values into the function rule to find the range values. </span>

Math <br><br><br> help pls!!<br><br> solve for x and y

Elan Coil [88]

Answer:

x = 7 , y= - 6

Step-by-step explanation:

4x = -2 - 5y ___(1)

4x= 10 - 3y ___(2)

so, now by simultaneous equations,

10 - 3y = - 2 - 5y

2y = -12

y = -6

if y = -6

then, 4x= 10 -3(-6)

4x =28

x = 7
