Answer: The answer is b 100+(-500)
Step-by-step explanation: If you solve for the original and this answer, they will both equal -400
Answer:
Step-by-step explanation:
your starting point is -9 so if you find one of your points multiply that by 5 and you have found your y axis
The average speed would be 600 km/hr.
Step-by-step explanation:
Let the original speed be 'x'
Let the decreased speed be 'x-200'
Distance = 600 km
Time increased by 30 minutes
According to question, it becomes,
So, The average speed would be 600 km/hr.
7x^2+x+9 - (<span>3x^2+4x-5)
= </span>7x^2 + x + 9 - 3x^2 - 4x + 5
= 4x^2 - 3x + 14
Answer:
y = 10.5qt
x = 12 qt
Step-by-step explanation:
0.6x+ 0.36y = 22.5 * 0.2
0.06x + 0.36y = 4.5
x + y = 22.5
x = 22.5 - y
0.06(22.5 - y) + 0.36y = 4.5
1.35 - 0.06y + 0.36y = 4.5
0.3y = 4.5 - 1.35
0.3y = 3.15
y = 3.15 / 0.3
y = 10.5 qt
x = 22.5 - y
x = 22.5 - 10.5
x = 12 qt
