I think the question here is to clean up this expression and simplify it.

-- Eliminate the first set of parentheses:

                 3 (8z - 1) = 24z - 3

-- Eliminate the second set of parentheses:

                -6 (5 + 3z) = -30 - 18z

-- Now write the whole thing without the parentheses:

                24z - 3    + 10    - 30 - 18z

-- Add up all the z's:

                24z - 18z  =  6z

-- Add up all the plain old numbers:

                 -3 + 10 - 30 = -23

-- Write the z's and plain old numbers together:

                     6z - 23

And that's exactly the same thing as the whole ugly mess
that we started out with in the question.

A hot air balloon hovers 75 feet above the ground. The balloon is tethered to the ground
DIA [1.3K]

Angle of elevation is 37°

<u>Step-by-step explanation:</u>

As we have the opposite side 75 ft to the angle and the hypotenuse 125 ft, we can find the sine value as,

sin θ = opp/ hyp

       = 75/125

     = 0.6

θ = sin⁻¹ (0.6) = 36.9°≈ 37°

So angle of elevation is 37°.

What is the slope-intercept equation of the line that includes (0,7) and (3,10)?
maksim [4K]

\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{10}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{10-7}{3-0}\implies \cfrac{3}{3}\implies 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-7=1(x-0)\implies y-7=x\implies y=x+7
