<span>To determine whether (−1,4) is a solution to the equation 3x+8y=29, substitute ...-1... for x and ...4... and for y.
In a pair of values like (-1, 4), the first coordinate, or entry, occupied by -1 always represents x.
Similarly, the second coordinate occupied by 4 represents y.
Answer: </span>substitute ...-1... for x and ...4... and for y.
Answer:
oh god i uh-
Step-by-step explanation:
L & C represent the number of days Alfred should water the lawn and wash his car respectively.
Each time he waters, there is 59 gallons used, and each time he washes car, 28 gallons used.
59L + 28C = 175 <the aim he set for himself>
59 gallons × L will then be the total amount of water he uses for watering lawn in a week.
28 gallons × C will then be the total amount of water he uses to wash his car every week.
The expression / answer : 59L + 28C = 175
Hope this helps! :)
