Answer:
14 and 16
Step-by-step explanation:
your adding 2 to each each time, if your looking for the multiplied awnser its 224
There are 60 seconds in one minute, and 60/5=12, so the race car would travel 100 feet every 5 seconds 12 times in one minute. You can simply multiply 100 by 12 to get your answer.
100x12=1200
The race car travels 1,200 feet in one minute.
Answer:
2) no change to the graphs
3) x = 1.47, y = 4.71
coordinates at intersection = (1.47, 4.71)
Step-by-step explanation:
4x + 3y = 20
3x - 2y = -5
2) Declan's way:
8x + 6y = 40
9x - 6y = -15
No change in graphs
4x + 3y = 20, 3y = 20 - 4x multiply by 2: 6y = 40 - 8x
3x - 2y = -5, 2y = 3x + 5 multiply by 3: 6y = 9x + 15
then:
40 - 8x = 9x + 15
simplify:
add 8x to each side:
17x + 15 = 40
subtract 15 from each side:
17x = 25
x = 1.47
3y = 20 - 4x
substitute for x:
3y = 20 - 4(1.47)
reduce:
3y = 14.12
y = 4.71
