Answer:

Step-by-step explanation:

Given expression is,

$\lim_{m \to \infty} \frac{4m^2-6m+1}{3m^2+5m+7}$

By dividing denominator and numerator of the given fraction by m²,

$\lim_{m \to \infty} \frac{\frac{4m^2-6m+1}{m^2} }{\frac{3m^2+5m+7}{m^2} }$

= $\lim_{m \to \infty} \frac{4-\frac{6}{m} +\frac{1}{m^2} }{3+\frac{5}{m} +\frac{7}{m^2} }$

We know that $\lim_{n \to \infty} \frac{1}{n}=0$

$\lim_{m \to \infty} \frac{4-\frac{6}{m} +\frac{1}{m^2} }{3+\frac{5}{m} +\frac{7}{m^2} }=\frac{4-0+0}{3+0+0}$

$=\frac{4}{3}$

Therefore, We can evaluate the limit of the expression by substituting ∞ in for m.

If one redskin and 4 golden roughs cost $1.65, whereas 2 redskins and 3 golden roughs cost $1.55, how much does each type or swe

Bas_tet [7]

Answer:

Redskins cost $0.25 and golden roughs cost $0.35.

Step-by-step explanation:

Let r be the cost of a redskin and g the cost of golden roughs. So we have the system of equations:

r + 4g = 1.65

2r + 3g = 1.55

Multiply the first equation by -2:

-2r - 8g = -3.30

Adding this to the second equation:

-5g = -1.75

g = 0.35.

Now substitute this into the first equation:

r + 4*0.35 = 1.65

r = 1.65 - 1.40

r = 0.25.
