Answer:

\huge{ \fbox{ \sf{x =  - 18}}}

Step-by-step explanation:

\text{4(7x + 3) =  - 3(2 - 9x)}

\text{Step \: 1 \:  : Distribute \: 4 \: through \: the \: parentheses}

\hookrightarrow{ \sf{28x + 12 =  - 3(2 - 9x)}}

\text{Step \: 2 \:  : Distribute \:  - 3 \: through \: the \: parentheses}

\hookrightarrow{ \sf{28x + 12 =  - 6 + 27x}}

\text{Step \: 3 \:  : Move \: 27x \: to \: left \: hand \: side \: and \: change \: its \: sign}

\hookrightarrow{ \sf{28x - 27x + 12 =  - 6}}

\text{Step \: 4 \:  : Move \: 12 \: to \: right \: hand \: side \: and \: change \: its \: sign}

\hookrightarrow{ \sf{28x - 27x =  - 6 - 12}}

\text{step \: 5 \:  : Collect \: like \: terms}

\text{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}

\hookrightarrow{ \sf{x =  - 6 - 12}}

\text{step \: 6 \:  : Calculate}

\text{ \underline{ Remember!}} :  \sf{ \: The \: negative \: integers \: are \: always \: added \: but \: posses \: the \: negative \: ( - ) \: sign.}

\hookrightarrow{ \boxed{ \sf{x =  - 18}}}

Hope I helped!

Best wishes ! :D

Answer: x=-18

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

Well it's hard to visually inspect this long text; let's look at it.

\begin{matrix} \textrm{Secs} & \textrm{GroupR} & \textrm{GroupS}  \\  45 & 1 & 0  \\ 50 & 2 & 1 \\ 55 & 1 & 1 \\ 60 & 2 & 2 \\ 65 & 1 & 0\\ 70 & 1 & 2 \\ 75 & 1 & 0 \\ 80 & 1 & 1 \\ 85 & 1 & 0 \\ 90 & 2 & 2 \\ 95 & 1 & 1 \\ 100 & 2 & 1 \\ 105 & 1 & 1 \\ 110 & 2 & 2 \\ 115 & 1 & 1 \\  120 & 2 & 1 \\ \end{matrix}

Based on visual inspection the averages look about the same.

Tell wether the relationship is a proportional relationship or not.
kondaur [170]
Although it is a straight line it does not pass through the origin or (0,0) so it is NOT a proportional relationship.

Find the solution of 5 times the square root of the quantity of x plus 7 equals negative 10, and determine if it is an extraneou
PilotLPTM [1.2K]
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3

Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
