Answer:

The answer will be [tex]\sqrt[3]{15}[/tex]

The required radical expression ∛15 is equivalent to the given expression [tex](15)^{1/3}[/tex].

Any expression that contains a radical symbol is considered a radical expression. To find the square roots, cubic roots, and higher, radical symbols are used. For example, √7, √6, and √11 are in the radial form.

The expression is given in the question, as follows:

[tex](15)^{1/3}[/tex]

We have to determine the equivalent expression in radical form​.

As per the question, we have

[tex](15)^{1/3}[/tex]

This can be also written as:

∛15

Thus, the radical expression ∛15 is equivalent to the given expression.

Answer: X = 7.

Step-by-step explanation: Move all terms that don't contain x to the right side and solve.

I'll go step-by-step.

1. Add 5 to both sides. 6x-(5+5)=37+5

2. Simplify 6x=42

3. Divide both sides by 6.   [tex]\frac{6x}{6} =\frac{42}{6}[/tex]

4. Then simplify/Divide. 42 / 6 = 7  

That's how you get 7!

X = 7

Hey there!

6x - 5 = 37

ADD 5 to BOTH SIDES

6x - 5 + 5 = 37 + 5

CANCEL out: -5 + 5 because it gives you 0

KEEP: 37 + 5 because it help solve for the x-value

NEW EQUATION: 6x = 5 + 37

SIMPLIFY IT!

6x = 42

DIVIDE 6 to BOTH SIDES

6x/6 = 42/6

CANCEL out: 6/6 because it give you 1

KEEP: 42/6 because it gives you the x-value

NEW EQUATION: x = 42/6

SIMPLIFY IT!

x = 7

Therefore, your answer is: x = 7

Answer:

a. decrease

b. recklessly

c. increase

Step-by-step explanation:

Suppose the large number of auto accidents in a small town results in new legislation that requires all citizens of the town to install new anti-lock brakes on their cars. These new brakes cut the time it takes a car to stop by 50%, allowing drivers to avoid collisions with other cars and pedestrians more easily. The new brakes decrease the probability that a vehicle will collide with another vehicle but also give drivers an incentive to drive more recklessly which could potentially increase the number of car accidents.

Because the new brakes cut the time it takes a car to stop by 50%, allowing drivers to avoid collision easily, drivers may become confident and drive recklessly which could potentially increase the number of car accidents

Step-by-step explanation:

Jace, who is exploring a cave that is 10 meters below the surface of the water is at - 10 meters.

Elevation of - 10 meters means we have to go down 10 meters.

According to the given question the surface of the water is at an elevation 0 meters, which person is located at an elevation of -10 meters.

- 10 meters means below 10 meters of the surface of the water.

Reading through options we observe that Jace, who is exploring a cave that is 10 meters below the surface of the water is -10 meter below the surface of water because, Water level it at 0 and the cave is below 10 meter to that so an expression can be formed as

0 - 10 = -10.

Answer:

B option is right

Step-by-step explanation:

These 3 will form a 3d system.

The correct option is A) parallel.

When two lines are perpendicular to the same line, they are parallel to each other.

In this case, a is perpendicular to b, and b is perpendicular to c. Therefore, a and c are parallel to each other.

To understand this, consider a scenario where a, b, and c represent three different lines:

Line a is perpendicular to line b.

Line b is perpendicular to line c.

Since line a is perpendicular to line b, it forms a right angle with line b. Similarly, line b is perpendicular to line c, forming a right angle with line c.

Now, imagine that line a and line c are not parallel.

In that case, they would intersect at some point, and we would have two perpendicular lines (a and b) intersecting at a third perpendicular line (b and c), which is not possible.

So, to maintain the condition that both a and b are perpendicular to the same line (b), we can conclude that a and c must be parallel to each other.

Hence, the correct option is A) parallel.

Answer:

Step-by-step explanation:

1. (10x + 3) + (-4x -2) --> sum means to add.

2. Combine like terms --> 10x - 4x = 6x; 3 - 2 = 1.

3. 6x + 1

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=\frac{3x+2}{2x-1}[/tex]

at x₁ = a,

[tex]f\left(x_1\right)=f\left(a\right)=\frac{3a+2}{2a-1}[/tex]

at x₂ = a+h,

[tex]f\left(x_2\right)=f\left(a+h\right)=\frac{3\left(a+h\right)+2}{2\left(a+h\right)-1}[/tex]

Using the formula to determine the average rate of change

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      [tex]=\:\frac{\frac{3\left(a+h\right)+2}{2\left(a+h\right)-1}-\frac{3a+2}{2a-1}}{a+h-a}\:\:\:\:\:\:\:[/tex]

as a+h-a = h, so    

                      [tex]=\frac{\frac{3\left(h+a\right)+2}{2\left(h+a\right)-1}-\frac{3a+2}{2a-1}}{h}[/tex]

Thus, the everarge rate of chnage:  [tex]\frac{\frac{3\left(h+a\right)+2}{2\left(h+a\right)-1}-\frac{3a+2}{2a-1}}{h}[/tex]

We can further simplify such as:

[tex]=\frac{\frac{3\left(h+a\right)+2}{2\left(h+a\right)-1}-\frac{3a+2}{2a-1}}{h}[/tex]

[tex]=\frac{-\frac{7h}{\left(2a-1\right)\left(2\left(h+a\right)-1\right)}}{h}[/tex]

[tex]=-\frac{\frac{7h}{\left(2a-1\right)\left(2\left(h+a\right)-1\right)}}{h}[/tex]

[tex]=-\frac{7h}{\left(2a-1\right)\left(2\left(h+a\right)-1\right)h}[/tex]

Cancel the common factor h

[tex]=-\frac{7}{\left(2a-1\right)\left(2\left(h+a\right)-1\right)}[/tex]
