\huge\text{Hey there!}

\huge\textbf{Equation: }

\mathbf{\dfrac{2x - 20}{3} = 2x}

\huge\textbf{SIMPLIFY IT or DISTRIBUTE:}

\mathbf{\dfrac{2}{3}x - \dfrac{20}{3} = 2x}

\huge\textbf{SUBTRACT 2x to BOTH SIDES:}

\mathbf{\dfrac{2}{3}x - \dfrac{20}{3} - 2x = 2x - 2x}

\huge\textbf{SIMPLIFY IT!}

\mathbf{- \dfrac{4}{3}x - \dfrac{20}{3} = 0}

\huge\textbf{ADD }\boxed{\rm{\bf \dfrac{20}{3}}}\huge\textbf{ to BOTH SIDES:}

\mathbf{-\dfrac{4}{3}x - \dfrac{20}{3} + \dfrac{20}{3} = 0 +  \dfrac{20}{3}}

\huge\textbf{SIMPLIFY IT!}

\mathbf{-\dfrac{4}{3}x = \dfrac{20}{3}}

\huge\textbf{MULTIPLY }\boxed{\rm \bf {\dfrac{3}{-4}}}\huge\textbf{ to BOTH SIDES:}

\mathbf{\dfrac{3}{-4}\times\dfrac{-4}{3}x = \dfrac{3}{-4}\times\dfrac{20}{3}}

\huge\textbf{SIMPLIFY IT!}

\mathbf{x = -5}

\huge\text{Therefore, your answer should be: \boxed{\mathsf{x = -5}}}\huge\chekmark

\huge\text{Good luck on your assignment \& enjoy your day!}

\large\displaystyle\text{$\begin{gathered}\sf \frac{2x-20}{3}=2x  \end{gathered}$}

Multiply both sides of the equation by 3.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20=6x \end{gathered}$}

Subtract 6x on both sides.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20-6x=0 \end{gathered}$}

Combine 2x and −6x to get −4x.

\large\displaystyle\text{$\begin{gathered}\sf -4x-20=0 \end{gathered}$}

Add 20 to both sides. Any value plus zero results in its same value.

\large\displaystyle\text{$\begin{gathered}\sf -4x=20 \end{gathered}$}

Divide both sides by −4.

\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{-4}  \end{gathered}$}

Divide 20 by −4 to get −5.

\large\displaystyle\text{$\begin{gathered}\sf x=-5 \ \ \to \ \ \ Answer \end{gathered}$}

Answer:

y = 0

Step-by-step explanation:

The given sinusoidal equation is y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right)

The general form of the sin function is presented as follows;

y = A·sin(B·(x - C)) + D

Where;

A = The amplitude

The period, T = 2·π/B

The frequency, f = B/2·π

C = The horizontal shift

D = The vertical shift

By comparison with the given sine function, we have;

The amplitude, A = 2

The frequency, f = B/2·π = π/2/(2·π) = 1/4

The frequency, f = 1/4 Hz

C = The horizontal shift = 3/(π/2) = 6/π

The vertical shift, D = 0

Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right), is therefore, the line;

y = 0.

PLS help question 9 and 10 or u can do only 9 it’s due tmrw
SCORPION-xisa [38]

Answer:

im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.

Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile.
Lerok [7]

Answer: 5 + 0.5m

Step-by-step explanation:

Let the number of miles be represented by m.

Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:

= 5 + 0.5m

For example if the number of miles taken is 100miles, the amount charged will be:

= 5 + 0.5m

= 5 + 0.5(100)

= 5 + 50

= $55

Trevon and his friends are going on a road trip that is 594 7/25 miles long. If they have 89 37/100 miles until their destinatio
Alenkinab [10]

Answer: 504.91 miles

Step-by-step explanation:

From the question, we are told that Trevon and his friends are going on a road trip that is 594 7/25 miles long and that they have 89 37/100 miles to reach their destination. To know how far that they've already traveled, we subtract 89 37/100 from 594 7/25.

= 594 7/25 - 89 37/100

Since the answer should be in decimal, we can change the fractions to decimal.

= 594 7/25 - 89 37/100

= [594 +(7/25 × 100)] - [89 + (37/100 × 100)]

= (594 + 0.28) - (89 + 0.37)

= 594.28 - 89.37

= 504.91 miles

They've already travelled 504.91 miles
