M1= 5 , M2=1

Explanation:

12-3m-4-5/m=0
8-3m-5/m=0
(8-3m-5/m=0) * m
8m-3m^2-5=0
8m-3m^2=5
m(8-3m)=5
m1=5
m2=> (8-3m)=5
3m=3
m2= 1

Answer:

m=1\\m=\frac{5}{3}

Step-by-step explanation:

12 - 3m = 4 + \frac{5}{m}

8=\frac{5}{m} +3m

Multiply the whole thing by m

8m = 5 +3m^{2}

3m^{2} -8m + 5 = 0

(3m^{2} -3m) + (-5m +5)

3m(m-1)-5(m-1)=0

3m-5=1\\m-1=0

m=1\\m=\frac{5}{3}

Identify the solution and graph of the given inequality. 34 > 3(2 − x)
zloy xaker [14]

Answer:

x > 28/3

Step-by-step explanation:

34 > 3(2 − x)

simplify the bracket

34 > 6 -3x

combine the like terms

34 - 6 > 3x

28 > 3x

divide by 3

x > 28/3

Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.

It is in slope intercept form; y = mx + b

where mx is the slope and b is the y-intercept;

x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times

And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.

Hope this helps!

Good luck.

58. Graph the function y=x^2+3x-18. How many real roots does the function have?
Airida [17]

9514 1404 393

Answer:

  58. 2 real roots; see attached for a graph

  59. -6, 3

Step-by-step explanation:

58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.

__

59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
