Let's say you have the equation

5x + 3y = 11

You are asked to test the ordered pair (1, 2) to see if it is a solution of the equation. A solution of the equation will make the equation a true statement. The ordered pair (1, 2) has 1 as its x-coordinate and 2 as its y-coordinate.
Substitute 1 for x and 2 for y in the equation. Then work it out to see if it is a true statement.

5x + 3y = 11

5(1) + 3(2) = 11

5 + 6 = 11

11 = 11

Since 11 = 11 is a true statement, the ordered pair (1, 3) is a solution of the equation.

The points (-7,-1) and (-8,6) fall on a particular line. What is its equation in point-slope form?
Arisa [49]

Answer:

y - 6 = -7(x + 8)

Step-by-step explanation:

Slope: m = (y2-y1)/(x2-x1) = (6 - -1)/(-8 - -7) = (6 + 1)/(-8 + 7) = 7/-1 = -7

Point-slope form: y - 6 = -7(x - -8)

=> y - 6 = -7(x + 8)

10.) A soccer team plays 104 tournaments in two
Gala2k [10]

Answer:

A. The Number of Lost games = 154 Games

B. Number of games won is greater than the number of games lost.

Step-by-step explanation:

A. how many games did they lose in both years?

Total Number of games = 104 tournaments x 3 Games in each tournament

Total Number of games = 312 Games

The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year

The No. of Lost games = 312 - 55 - 103

The No. of Lost games = 154 Games

B. Is the number of games won greater than the number of games lost?

Total Number of Games won = 158 Games

Total Number of Games lost = 154 Games

Hence, Total Number of Games won is greater than the Total Number of Games lost.
