Answer:
x= −7/5
Step-by-step explanation:
Step 1: Distribute and combine like terms
3(x−6)−8x=−2+5(2x+1)
(3)(x)+(3)(−6)+−8x=−2+(5)(2x)+(5)(1)(Distribute)
3x+−18+−8x=−2+10x+5
(3x+−8x)+(−18)=(10x)+(−2+5)(Combine Like Terms)
−5x+−18=10x+3
−5x−18=10x+3
Step 2: Subtract 10x from both sides.
−5x−18−10x=10x+3−10x
−15x−18=3
Step 3: Add 18 to both sides.
−15x−18+18=3+18
−15x=21
Step 4: Divide both sides by -15.
Hope this helps! :)
Polynomials in the fourth degree are called quartic equations. In solving the roots of polynomials, there are techniques available. For quadratic equations, you use the quadratic formula. For cubic equations, you use the scientific calculator. But for quartic equations and higher, it is very complex. The method is very lengthy and can get very messy because you introduce a lot variables. So, I suggest you do the easiest method to estimate the roots.
Graph the equation by plotting arbitrary points. The graph looks like that in the figure. The points at which the curve passes the x-axis are the solution which are encircled in red.In approximation, the rational roots or zero's are
-3.73, -1, -0.28 and 2.
The final answer is:
7x120=840
Answer:
<h2>J. <u>42 </u>= <u> x </u></h2><h2> 57 100</h2>
Step-by-step explanation:
last year won 57 games
this year won 15 games
the difference is 57 - 15 = 42,
this means it drops 42 / 57 = 0.73 (100%) ≈ 73%
therefore, the percentage decrease from the given choices is: J
<u>42 </u>= <u> x </u>
57 100
The answer is 4. 76 divided by 19 is 4. 19 is the only number that can go into 19. hope this helps :)
