(C), because in a function you cannot repeat any of the x factors, in all A B and D you see that they repeat a number in the x, therefore the only answer choice left is C.

Answer:

The correct option is C.

Step-by-step explanation:

Consider the provided information.

A function is defined as a relation of input and output where each input has only one possible output or Each x value is associated with only one y value.

Now consider the provided tables

Option A has two y values for x = -15. i.e 16 and 22. Thus, this is not a function.

Option B has two y values for x = -3 i.e 16 and 15. Thus, this is not a function.

Option C has only one y values for each x value. Thus, this is a function.

Option D has two y values for x = -7 i.e 14 and 15. Thus, this is not a function.

Hence, the correct option is C.

Answer:

steeper

Step-by-step explanation:

y = mx + c where m is the slope and c is the y-intercept.

The slope has been changed from 2 to 4. The higher the slope, the steeper it is. Thus, the slope is steeper now.

what variable expression should you subtract from both sides of the equation so that you are left with no variables on the right
Scorpion4ik [409]

SOLUTION:

Step 1:

In this question, we are given the following:

Step 2:

The details of the solution are as follows:

What variable expression should you subtract from both sides of the equation so that you are left with no variables on the right-hand side?

The variable expression is: subtract 5x from both sides so that you are left with no variables on the right-hand side

\begin{gathered} 6x\text{ - 10 = 5x + 15} \\ \text{Subtract 5 x from both sides, we have that:} \\ 6x\text{ - 5x - 10 = 5x - 5x + 15} \\ x\text{ - 10 = 15} \\ \text{Now, add 10 to both sides, we have that:} \\ x\text{ - 10 + 10 = 15 + 10} \\ x\text{ = 25} \\ \text{check:} \\ 6x\text{ - 10 = 5x + 15} \\ \sin ce,\text{ x = 25 , we have that:} \\ 6(25)\text{ - 10 = 5(25) + 15 } \\ 150\text{ - 10 = 125+ 15= 140 ( COR}\R ECT) \end{gathered}

CONCLUSION:

The final answer is:

x\text{ = 25}

The radius of the front wheel of Paul's bike is 63cm. Paul goes for a cycle and travels 69.89km. How many full revolutions did P
Rudiy27

Answer: 17,649

Step-by-step explanation:

Given

The radius of the cycle is r=63\ cm

Distance traveled by Paul is 68.89\ km

Distance traveled by one complete revolution of wheel is equivalent to circumference of wheel i.e.

\Rightarrow 2\pi r\\\\\Rightarrow 2\times \dfrac{22}{7}\times 63\\\\\Rightarrow 396\ cm\ \text{or}\ \text{3.96}\ m

No of revolution made by wheel

\Rightarrow n=\dfrac{69.89\times 1000}{3.96}\\\\\Rightarrow n=17,648.9899\approx 17,649
