Answer:

x=43

Step-by-step explanation:

Given equation:

25=5(3x-4)^{\frac13}

Divide both sides by 5:

\implies 5=(3x-4)^{\frac13}

Cube both sides:

\implies 5^3=((3x-4)^{\frac13})^3

\implies 125=(3x-4)^{\frac33}

\implies 125=(3x-4)^1

\implies 125=3x-4

Add 4 to both sides:

\implies 129=3x

Divide both sides by 3:

\implies x=43

Answer:

<u>x = 43</u>

Step-by-step explanation:

  • 25 = 5∛(3x - 4)
  • On cubing the entire expression :
  • 15625 = 125(3x - 4)
  • 3x - 4 = 125
  • 3x = 129
  • <u>x = 43</u>

Determine if the function is linear or nonlinear . EXPLAIN​
nordsb [41]

Answer:

it is not linear

Step-by-step explanation:

Linear function means that same increments in x yield uniform increments in y.

First 2 lines: x grows from -5 to 0, so increment in x is 5. For said interval, y grows from 3 to 7, so increment in y is 4.

Then, x grows from 0 to 5, so increment in x is again 5. Now, for the same increase of x, y grows from 7 to 10, so increment now in y is 3.

In the first "5" interval of x, y grew 4, and in the second "5" interval of x y grew 3 ⇒ it is not linear.

The function would have been linear, if last y value had been 11.

Answer:

x=17/4

Step-by-step explanation:

(x-3)/(x+2)=1/5

cross product

1(x+2)=5(x-3)

x+2=5x-15

5x-x-15=2

4x-15=2

4x=2+15

4x=17

x=17/4

At the park, 4/7 of the children are boys. if there are 8 boys at the park, how many are girls?
Oksana_A [137]
There are 4/7 boys, so there are 3/7 girls.

Let the total number of children be x.

4/7x = 8
1/7x = 8 ÷ 4
1/7x = 2
3/7x = 2 x 3
3/7x = 6

There are 6 girls.

What is the rate of change ?
postnew [5]
The rate of change is also called the slope
 the formula foe the rate of change is (y2-y1) / (x2-x1)

x1 = -3
x2 = 6
y1 = 14
y2 = -1
 rate of change = (-1 - 14) / (6- (-3)
= -15 / 9
= -5/3
