2(3x-1)=8x-20
SIMPLY
6x-2=8x-20
SUBTRACT 6x ON BOTH SIDES
-2=2x-20
ADD 20 TO BOTH SIDES
18=2x
DIVIDE 2 ON BOTH SIDES
X=9
SUBSTITUTE
3(9)-1
27-1
26
BC=26
The answer is A.
You can get this by modeling the function. It's slope and y intercept will yield the equation y = -.5x +1.5. Then you can try the ordered pairs in that, all of which work.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = -1x - 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = -1(-3) - 4
- Multiply: f(-3) = 3 - 4
- Subtract: f(-3) = -1
Answer:
given us,
mass= 25g
density= 5 g/ cm2
here,
volume = mass/ density
= 25g/ 5g cm2
= 5cm2
Step-by-step explanation:
cm2 is the square
