stepan [7]3 years ago
3 0

Answer:

\fbox{ \huge{ \sf{ a =  - 8}}}

Step-by-step explanation:

\bigstar{ \sf{ \: 19 =  - 3a - 5}}

\tt{Step \: 1 \: } : Swap the sides of the equation

\longmapsto{ \sf{ - 3a - 5 = 19}}

\tt{Step \: 2 \: } : Move 5 to right hand side and change it's sign

\longmapsto{ \sf{ - 3a = 19 + 5}}

\tt{Step \: 3 \: } : Add the numbers : 19 and 5

\longmapsto{ \sf{ - 3a = 24}}

\tt{Step \: 4 \: } : Divide both sides by -3

\longmapsto{ \sf{ \frac{ - 3a}{ - 3}  =  \frac{24}{ - 3}}}

\tt{Step \: 4} : Calculate

\longmapsto{ \sf{a = -  8}}

\sf ∴ \: the \: value \: of \: a \: is \:  - 8.

Based on the table of values below, find the slope between points where x = 1 and where x = 4.
Andre45 [30]
\bf \begin{array}{llll}
x&\boxed{1}&3&\boxed{4}\\\\
y&\boxed{8}&6&\boxed{-1}
\end{array}\\\\
-------------------------------\\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ 1}}\quad ,&{{ 8}})\quad 
%   (c,d)
&({{ 4}}\quad ,&{{ -1}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-1-8}{4-1}\implies \cfrac{-9}{3}\implies -3

The owner of a sporting goods store in Phoenix, Arizona surveys her customers to determine the proportion of customers that play
BabaBlast [244]

Answer:

C

Step-by-step explanation:

This is a sample proportion where p^ represents the sample proportion.

If we have p^ = 0.6, it means about 60% of the sample are in agreement with or significant to the case study.

The case study here is 'customers that play racquetball' and p^ was 0.16.

This means that 16% of the customers of the sample said they play racquetball.

A function is created to represent the costs of living per person in the family. What restrictions would be made to the domain?
Nitella [24]

Let

x-------> the number of persons in the family

f(x)------> the function represent the cost of living

we know that

The domain of the function  would only include positive integers, because the number of persons can not be negative or a fraction

The range of the function would only include positive numbers, because the cost can not be negative

therefore

<u>the answer is the option B</u>

The domain would only include positive integers.
