Answer:
=-5ab
Step-by-step explanation:
Rewrite: -15 as 3*5
Rewrite: -5 *2*2 as 1*5
Rewrite: 10 *3 as 6*5
=6* 5ab +4 *5ab +3ab
Factor out common term 5ab
=5ab(6-4-3)
=-5ab
1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)
2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
Answer: 15 pounds of potatoes.
Step-by-step explanation:
Kevin will perform basic multiplication to find how many potatoes he needs for all of the guests. Since each person requires 2 1/2 pound of potatoes and there are a total of 6 guests, multiplying these two values will find the pounds of potatoes that are needed for all of the guests.
2 1/2 * 6 = 15 pounds of potatoes
Therefore, Kevin needs 15 pounds of potatoes to make potato casserole for everyone at the dinner party.
