Answer:
A. The system has no solutions
Step-by-step explanation:
Step 1: Check to see if the 2 lines share 1 slope
slope of blue line =
slope of red line =
Step 2: Realize that lines with the same slope never touch
We know lines with the same slope are parallel to each other so they won't collide
Step 3: Know what the question is asking you
When they ask for solutions to the system of equations they are asking you to find out where they intersect
Step 4: Find answer
Because we know this is a parallel line they will never intersect causing this system to never have an answer or solution
Therefore the answer is A. The system has no solutions
Answer:
3. 15 Cubes
4. 60 ft per sec , 180 ft
5. 58 yards per min
6. $7.50, $18.00
Step-by-step explanation:
3. Number of Cubes in 7 bowls = 35
Number of Cubes in 1 bowls =
Number of Cubes in 3 bowls =
4. Distance ran by Zebra = 420 ft
Time taken = 7 seconds
Speed = =60 ft per sec
Hence
Distance = speed x time
Distance covered in 30 seconds = 60 x 30 = 180 Ft
5. Distance travelled = 870 yards
Time taken = 15 mins
Speed = yards per min
6. Cost of 3 pounds of apple = $4.50
Cost of 1 pounds of apple = =$1.50
Cost of 5 pounds of apple = 5 x $1.50 =$7.50
Cost of 12 pounds of apple = 12 x $1.50 =$18.00
