To solve this question we must understand the concept of indices.
What are Indices?Indices in mathematics show the power to which an expression or variable is raised.
Here, the correct format of the equation given in the question as follows:
[tex]\mathbf{2 \sqrt[3]{3x +2}} \mathbf{= \sqrt[3]{4x -9} }[/tex]
[tex]2(3x+2)^{1/3} = (4x -9)^{1/3} \\ \\ (6x + 4)^{1/3} =(4x -9)^{1/3}[/tex]
Multiply the power of both sides by 3
(6x + 4) =(4x -9)
6x - 4x = -9 + 4
2x = -5
x = -5/2

A rectangular plot of land is 90 ft long and 105 ft wide. On a map, the length is 3.6 in. Identify the width on the map.
Answers
Answer:
4.2 in
Step-by-step explanation:
90÷3.6 = 25
The plot of land is 25 times bigger than the map's scale. You have to divide 105 by 25 to get the same scale as the length (3.6 in.)
105÷25 = 4.2

The ratio of taxis to buses to bikes
is 12:5:18.
How many buses are there if there
are 72 bikes?
Answers
Answer:
20 buses
Step-by-step explanation:
Using the given ratio, we can see that for every 12 taxis, there are 5 buses and 18 bikes.
To get from 18 bikes to 72 bikes, we multiply by 4. Therefore, to figure out the number of buses, we multiply it by 4.
5 * 4 = 20

Find values for a and b for which x = 4 is a solution of the equation shown.
ax + 4 = 5x + b
Answers
The values of a and be for which x = 4 is a solution of the equation shown.
ax + 4 = 5x + b are infinitely many
The given equation is:
ax + 4 = 5x + b
To find the values of a and b in the equation at x = 4, substitute x = 4 into the equation
4a + 4 = 5(4) + b
4a + 4 = 20 + b
Collect like terms
4a - b = 20 - 4
4a - b = 16
Since there are two unknowns in just a single equation, the equation has more than 1 solution.
The values of a and be for which x = 4 is a solution of the equation shown.
ax + 4 = 5x + b are infinitely many

Both graphs have a y-intercept of (0,1) and y=6^x is steeper
Step-by-step explanation:
Plug in 0 for x to find the y-intercept. THey would both be raised to the 0th power meaning both y's equal 1. So, they both have the y-intercept of (0,1).
y=6^x is steeper becuase when you graph it, you can see it is. Also of course 6 is higher than 3.
