2.396 which is also a.
Answer:
2.396
Step-by-step explanation:
The units of measurement go like this:
Kilo, hecto, deca, unit, deci, centi, mili
When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right
If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters

Can somebody please help me out with this. We have to do it point slope form.
[tex]y - y_{1} = m( x - x_{1})[/tex]
Answers
Explanation:
The formula y - y1 = m(x - x1) is usually described as the 'point-slope form' for the equation of a line. It is useful because if you know one point on a certain line and the slope of that certain line, then you can define the line with this type of formula and, thus, find all the other points on that certain line.

Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8
Answers
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
-x+7=-0.5x^10 -4.5^10
am I getting ...!?
Answer:
(-1,6) and (-7,0)
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
times both sides by -2
2x-14=(x-3)^2-16
expand
2x-14=x^2-6x+9-16
add 14-2x to both sides
0=x^2-8x+7
factor
0=(x-7)(x-1)
set to zero
0=x-7
7=x
0=x-1
1=x
so find y
y=-x+7
y=-1+7
y=6
or
y=-7+7
y=0
