Well you have to make the powers line up so we know r^4 is the highest and you work your way down so
0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r
So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)
R^4-5r^3-8r^2
That's your answer
Answer:
x = - 4
Step-by-step explanation:
Given
r(x) = - 5x - 1 and r(x) = 19, then equating the right sides gives
- 5x - 1 = 19 ( add 1 to both sides )
- 5x = 20 ( divide both sides by - 5 )
x = - 4
Answer:
z>1
Step-by-step explanation:
the symbol that is used for greater than is: >
Answer :135
Answer reasoning : since X equals five you add 5+4 for the parentheses then 3×5 then multiply the 9 and the 15.
2 lines intersect at (1,2)
so answer is Yes.
(1,2) is the solution to the system.
