Answer:

see explanation

Step-by-step explanation:

Substitute the given values of x into f : x → $\frac{3}{7}$ x + 4

x = - 14 → ( $\frac{3}{7}$ × - 14) + 4 = (3 × - 2) + 4 = - 6 + 4 = - 2

x = 28 → ( $\frac{3}{7}$ × 28) + 4 = (3 × 4) + 4 = 12 + 4 = 16

x = $\frac{7}{8}$ → ( $\frac{3}{7}$ × $\frac{7}{8}$ ) + 4 = $\frac{3}{8}$ + 4 = $\frac{3}{8}$ + $\frac{32}{8}$ = $\frac{35}{8}$

x = - $\frac{2}{9}$ → ( $\frac{3}{7}$ × - $\frac{2}{9}$ ) + 4 = ( $\frac{1}{7}$ × - $\frac{2}{3}$ ) + 4 = - $\frac{2}{21}$ + $\frac{84}{21}$ = $\frac{82}{21}$

Answer:

See below in bold.

Step-by-step explanation:

1. 3/7 * -14 + 4

= -6 + 4

= -2.

2. 3/7 * 28 + 4

= 12 + 4

= 16.

3 3/7 * 7/8 + 4

= 3/8 + 4

= 35/8 or 4 3/8.

4. 3/7 * -2/9 + 4

= -6/63 + 4

= -2/21 + 4

= -82/21 or -3 19/21.

Subtract and solve for "d":

3d = 18

d = 6 (# of dimes)

Identify the functions that are continuous on the set of real numbers and arrange them in ascending order of their limits as x t

Studentka2010 [4]

Answer:

g(x)<j(x)<k(x)<f(x)<m(x)<h(x)

Step-by-step explanation:

1. $f(x)=\frac{x^2+x-20}{x^2+4}$

The denominator of f is defined for all real values of x

Therefore, the function is continuous on the set of real numbers

$\lim_{x\rightarrow 5}\frac{x^2+x-20}{x^2+4}=\frac{25+5-20}{25+4}=\frac{10}{29}=0.345$

3. $h(x)=\frac{3x-5}{x^2-5x+7}$

$x^2-5x+7=0$

It cannot be factorize .

Therefore, it has no real values for which it is not defined .

Hence, function h is defined for all real values.

$\lim_{x\rightarrow 5}\frac{3x-5}{x^2-5x+7}=\frac{15-5}{25-25+7}=\frac{10}{7}=1.43$

2. $g(x)=\frac{x-17}{x^2+75}$

The denominator of g is defined for all real values of x.

Therefore, the function g is continuous on the set of real numbers

$\lim_{x\rightarrow 5}\frac{x-17}{x^2+75}=\frac{5-17}{25+75}=\frac{-12}{100}=-0.12$

4. $i(x)=\frac{x^2-9}{x-9}$

x-9=0

x=9

The function i is not defined for x=9

Therefore, the function i is not continuous on the set of real numbers.

5. $j(x)=\frac{4x^2-7x-65}{x^2+10}$

The denominator of j is defined for all real values of x.

Therefore, the function j is continuous on the set of real numbers.

$\lim_{x\rightarrow 5}\frac{4x^2-7x-65}{x^2+10}=\frac{100-35-65}{25+10}=0$

6. $k(x)=\frac{x+1}{x^2+x+29}$

$x^2+x+29=0$

It cannot be factorize .

Therefore, it has no real values for which it is not defined .

Hence, function k is defined for all real values.

$\lim_{x\rightarrow 5}\frac{x+1}{x^2+x+29}=\frac{5+1}{25+5+29}=\frac{6}{59}=0.102$

7. $l(x)=\frac{5x-1}{x^2-9x+8}$

$x^2-9x+8=0$

$x^2-8x-x+8=0$

$x(x-8)-1(x-8)=0$

$(x-8)(x-1)=0$

$x=8,1$

The function is not defined for x=8 and x=1

Hence, function l is not defined for all real values.

8. $m(x)=\frac{x^2+5x-24}{x^2+11}$

The denominator of m is defined for all real values of x.

Therefore, the function m is continuous on the set of real numbers.

$\lim_{x\rightarrow 5}\frac{x^2+5x-24}{x^2+11}=\frac{25+25-24}{25+11}=\frac{26}{36}=\frac{13}{18}=0.722$

g(x)<j(x)<k(x)<f(x)<m(x)<h(x)

Answer:

$x\geq -\frac{15}{2}$

Step-by-step explanation:

add 4 on both sides

leaves you with 15 on the right side

you then divide by negative 2
