Answer:

31 1/2 inches on the map

Step-by-step explanation:

The scale is 1.5 inches to 4 miles

He went 84 miles

We can use proportions to solve

1.5 inches x inches

----------------- = ------------

4 miles 84 miles

Using cross products

1.5 * 84 = 4x

126 = 4x

Divide by 4

126/4 = 4x/4

31.5 =x

31 1/2 inches on the map

Which statement describes the behavior of the function f(x)=3x/4-x?

Oksana_A [137]

Answer:

The graph approaches –3 as x approaches infinity. Option a is correct.

Step-by-step explanation:

The given function is

$f(x)=\frac{3x}{4-x}$

We have to find value of function as x approaches infinity. Take limit both sides as x approaches to infinity.

$\lim_{x\rightarrow \infty}f(x)=\lim_{x\rightarrow \infty}\frac{3x}{4-x}$

Taking x common from the denominator.

$\lim_{x\rightarrow \infty}f(x)=\lim_{x\rightarrow \infty}\frac{3x}{x(\frac{4}{x}-1)}$

Cancel out common factor x.

$\lim_{x\rightarrow \infty}f(x)=\lim_{x\rightarrow \infty}\frac{3}{\frac{4}{x}-1}$

Apply limits.

$\lim_{x\rightarrow \infty}f(x)=\frac{3}{\frac{4}{\infty}-1}$

$\lim_{x\rightarrow \infty}f(x)=\frac{3}{0-1}$

$\lim_{x\rightarrow \infty}f(x)=-3$

Therefore the graph approaches –3 as x approaches infinity.

Solve for x: 3 − (2x − 5) < −4(x + 2)

Firdavs [7]

Answer:

A. x < -8 (first option)

Step-by-step explanation:

$3 - (2x - 5) < - 4(x + 2)$

$3 - 2x + 5 < - 4x - 8$

$8 - 2x < - 4x - 8$

$- 2x + 4x < - 8 - 8$

$2x < - 16$

$\boxed{\green{x < - 8}}$
