Which of the following is a solution to the equation y = 3x - 1 ?

Korvikt [17]

One way of determining the answer is by substituting the values to the equation. It is done as follows:

A. (4,1)
y = 3x - 1
1 = 3(4) - 1 = 11 -------> not equal

B. (2,5)
y = 3x - 1
5 = 3(2) - 1 = 5 --------> equal

C. (4,3)
y = 3x - 1
3 = 3(4) -1 --------------> not equal

D. (0, -3)
y = 3x - 1
-3 = 3(0) -1 = -1 ---------> not equal

Help pleaseee Im trying to get an A in class

likoan [24]

Answer:

191

Step-by-step explanation:

Sorry it's sideways. I drew a box chart for this. First, fill in what you know: the number of white and black beads Ally has. Then, calculate how many black beads Betty has (Ally's number, 59, minus 35.) 59-35 = 24.

They tell you the total number of beads is 346. Add up Ally's total to get 131, then subtract that from 346. That's Betty's total beads, 215.

Last, subtract the 24 black beads Betty has from the 215 total to get 191.
