It would be 1,300. When rounding, you'd need to look at the number to the right of the place you're rounding to. In this case, you're rounding to the hundreds place (the 2), so you look at the number to the right (7). To know if you round up or down use this:
Round down= 0-4
Round up= 5-9
You do this by converting to vertex form a(x - b)^2 + c where the axis of symmetry is x = b
the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one
x^2 - 6x - 1 = (x - 3)^2 -9-1
the last option is the correct one
First divide 3.5 by 2 which equals 1.75. Then do 1.75*3 which equals 5.25. So he drinks 5.25 liters in one hour.
Answer:
x=4
Step-by-step explanation:
3^(x-1)=27
=>3^(x-1)=3³
=>(x-1)=3
=>x=4
Answer:
y = -3x/2 +8
Step-by-step explanation:
3x+2y=16
1. Isolate the y variable by transposing 3x to the right side.
2y=-3x+16
2y/2=-3x/2+16/2
y=-3x/2+8
Final answer: y = -3x/2 +8
