The answer is b
y=-2x+3
explanation:
m= slope
b= y intercept
the line intercepts with y at point 3, giving you y=mx+3. you get the -2x from the slope of the line that is going downhill at a slope of -2. the answer is y=-2x+3
Answer:
C. Undefined
Step-by-step explanation:
Any vertical line is going to have an undefined slope. Plug in any two points from that line, and the formula will give you an undefined number.
Hope this helps!
= A/x +B/(x -2) +C/(x -4)
To find A, multiply the expression by x and evaluate at x=0.
.. A = 24/((-2)*(-4)) = 3
To find B, multiply the expression by x-2 and evaluate at x=2.
.. B = (18*2^2 -68*2 +24)/(2*(2-4)) = -40/-4 = 10
To find C, multiply the expression by x-4 and evaluate at x=4.
.. C = (18*4^2 -68*4 +24)/(4(4 -2)) = 40/8 = 5
The partial fraction decomposition is
.. = 3/x +10/(x -2) +5/(x -4)

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
