Answer:
9r³ + 2r⁴
Step-by-step explanation:
Step 1: Write expression
4r³ + 3r⁴ - (r⁴ - 5r³)
Step 2: Distribute negative
4r³ + 3r⁴ - r⁴ + 5r³
Step 3: Combine like terms
9r³ + 2r⁴
9514 1404 393
Answer:
y -8 = 1/5(x -3)
Step-by-step explanation:
The point-slope form of the equation of a line is ...
y -k = m(x -h) . . . . . . line through point (h, k) with slope m
The given equation y = 1/5(x +4) matches this form with m=1/5. The parallel line will have the same slope.
This means you want a line through point (3, 8) with slope 1/5. Putting these values in the point-slope form gives ...
y -8 = 1/5(x -3)
Well say you have 10% and you want to change it to a decimal. 10% is the same as 10/100 or 10 divided by 100 which makes us move the decimal to the left twice.
