Enter the value of a and b that complete the sum: 3/x + 5/x^2 = ax+b/x^2

Aleksandr [31]

Answer:

a= $\frac{3}{x^{2} }$

b=5

Step-by-step explanation:

we are given

$\frac{3}{x} }$ + $\frac{5}{x^{2} }$ =ax+ $\frac{b}{x^{2} }$

we will compare both sides of equaion

$\frac{b}{x^{2} }$ = $\frac{5}{x^{2} }$

comparing both sides we get

b=5

and

$\frac{3}{x} }$ =ax

a= $\frac{3}{x^{2} }$

hence

a= $\frac{3}{x^{2} }$

and b=5

Help with this question ??

NNADVOKAT [17]

Answer: 12 tables minimum, 15 max.

Step-by-step explanation:

If you substitute 14 in an inequality

200c + 500t >= 8800

200(14) + 500t and solve for t, you get t must be at least 12.

C +T cannot exceed 29

So figure 14 +12 =26 so they could sell up to 15 tables and not go over 29.

You will have to enter the t values 12,13,14,15
