Charlie gathered data about the time it takes him to complete a crossword puzzle and the number of clues in the puzzle. He used

a graphing tool to organize the data in a scatter plot and find the line of best fit.
He found the relationship between the number of clues, x, and the time required to complete the puzzle, y, is modeled by the equation y = 0.376x + 15.48, and the correlation coefficient for the data is 0.219.

Could the line of best fit be used to make reliable predictions about the time it takes Charlie to complete a crossword puzzle?

How do I solve 34-5x+2(x-2)=15
LenKa [72]
34-5x+2(x-2)=15      1st get rid of () by distributing the 2.
34-5x+2x-4=15         Now collect like terms.
30-3x=15                  Get -3x by itself by subtracting 30 in both sides.
-3x=-15                     You want X by itself so divide by -3 on both sides.
x=5

The equation 3x+4=5x-4 has the solution set {4}. explain why the equation (3x+4)+4=5x-4)+4 also has the solution set {4}
cestrela7 [59]
Notice that the terms in parentheses on both sides of the equation are added to 4.

(3x + 4) + 4 = (5x - 4) + 4


So we can set the equation as.

3x + 4 = 5x - 4


Subtract 3x on both sides of equation.

4 = 2x - 4


Add 4 on both sides of equation.

8 = 2x


Divide both sides of equation by 2.

4 = x


4 is the only value that satisfies the statement.
