Answer:

\boxed {x = -75}

Step-by-step explanation:

Solve for the value of x:

\frac{1}{3}x + 2 = \frac{1}{5}x - 8

-Take \frac{1}{5}x and subtract it from \frac{1}{3}x:

\frac{1}{3}x + 2 - \frac{1}{5}x = \frac{1}{5}x - \frac{1}{5}x - 8

\frac{2}{15}x + 2 = -8

-Subtract 2 to both sides:

\frac{2}{15}x + 2 - 2 = -8 - 2

\frac{2}{15}x = -10

-Multiply both sides by \frac{15}{2}, which is the reciprocal of \frac{2}{15}.

x = -10 \times (\frac{15}{2})

x = \frac{-10 \times 15}{2}

x = \frac{-150}{2}

-Divide -150 by 2:

x = \frac{-150}{2}

\boxed {x = -75}

So, the value of x is -75.

Which statements apply to the expression
bagirrra123 [75]

Answer:

A, C, D, F

Step-by-step explanation:

Given the expression : (3/5)³

Recall :

a^b where, a = base ; b = exponent

In ; (3/5)^3

Base = 3/5 ; exponent = 3

Similarly ;

a^b = a in b places

(3/5)^3 = (3/5) * (3/5) * (3/5)

(3/5) * (3/5) * (3/5) = (3*3*3) / (5*5*5) = 27/125

Hence, A, C, D and F are all correct

Given the function g(x) = (5 - x)^3 , what is the value of g(2)?
11111nata11111 [884]

Answer:

g(2) = 27 is the answer.

Step-by-step explanation:

If the function is g(x) = (5 - x)³

By expanding (5 - x)³ = 5³-3.5²x + 15x² -x³

g(x) = 125 - 75x + 15x² - x³

Now g(2) = 125 - 75×2 + 15×(2)² - 2³

        g(2) = 125 - 150 + 60 - 8

               = -25 + 60 - 8

              = 35 - 8 = 27

Or directly putting the value x = 2 in g(x) we get

g(2) = (5 - 2)³ = 3³ = 27

Therefore g(2) = 27 is the answer.

HELP! I am confused since the -5 was added, so would it be the slope or would -7 be the slope?
In-s [12.5K]

Answer:

slope = 35; y-intercept = -45

Step-by-step explanation:

Function f(x) is written in the slope-intercept form, y = mx + b.

f(x) = -7x + 9

You compare it with

f(x) = mx + b, and you see that m, the slope, is -7, and b, the y-intercept is 9.

Now we deal with function h(x).

h(x) = -5(-7x + 9)

This is not written in the y = mx + b form, but we can put it in that form by distributing the -5.

h(x) = 35x - 45

Now, h(x) is written in the y = mx + b form. We see clearly that m = 35, so the slope of function h is 35. We also see that b, the y-intercept is -45.

Answer: slope = 35; y-intercept = -45
