Answer:

Undefined

Step-by-step explanation:

There is no slope it's a vertical line, think of a snowboarder, a horizontal line is y=0, this is zero fun, but going straight down a cliff, he would be yelling undefined.

Solve the equation. Then check your solution.4- 3/5(3a+4)=7A. -7.4B. -6C. 3D. -3

Evgesh-ka [11]

Answer: a = -3

Explanations:

The given equation is:

$4\text{ - }\frac{3}{5}(3a+4)\text{ = 7}$

This can be re-written as:

$4-\frac{3(3a+4)}{5}=7$

Collect like terms:

$\begin{gathered} -\frac{3(3a+4)}{5}=\text{ 7 - 4} \\ -\frac{3(3a+4)}{5}=\text{ 3} \end{gathered}$

Cross multiply:

$\begin{gathered} -3(3a+4)\text{ = 3}\times5 \\ -3(3a+4)=\text{ 15} \\ \text{Expand the bracket} \\ -9a\text{ - 12 = 15} \\ \text{Collect like terms} \\ -9a\text{ = 15 + 12} \\ -9a\text{ = 27} \\ \text{Divide both sides by -9} \\ \frac{-9a}{-9}=\frac{27}{-9} \\ a\text{ = -3} \end{gathered}$

To verify if the solution is correct, substitute a = -3 into the question given. If the Right Hand Side equals the Left Hand Side, then the solution is correct.

$\begin{gathered} 4-\frac{3(3a+4)}{5}=\text{ 7} \\ \text{Substitute a = }-3 \\ 4\text{ - }\frac{3(3(-3)+4)}{5}\text{ = 7} \\ 4\text{ - }\frac{3(-9+4)}{5}\text{ = 7} \\ 4\text{ - }\frac{3(-5)}{5}\text{ = 7} \\ 4\text{ - }\frac{-15}{5}=\text{ 7} \\ 4-(-3)=7 \\ 4+3=7 \\ 7=7 \end{gathered}$

Since the Left Hand Side = Right Hand Side = 7, the solution a = -3 is correct

11 Yesterday 170 guests at a hotel called for room service, and 255 guests did not call for room

-Dominant- [34]

Answer:

The percentage of the guests at this hotel called for room service yesterday is 40%

Step-by-step explanation:

We are given

total number of guests called for room services =170

total number of guests did not called for room services =255

now, we can find total number of guests

Total number of guests =(total number of guests called for room services)+(total number of guests did not called for room services)

so,

total number of guests is

=170+255

=425

now, we can find percentage

percentage of the guests at this hotel called for room service yesterday is

So,

The percentage of the guests at this hotel called for room service yesterday is 40%
