Answer:

8) answer=5 9)answer=15

Step-by-step explanation:

all you have to do is replace in the following formula

\sqrt{(x2-x1)^{2}+ (y2-y1)^{2}} =d

Where

X1: is the first number of the first point

Y1: is the second number of the first point

X2:  is the first number of the second point

Y2: is the second number of the second point

you replace in the formula and solve

Gave needs 60 liters of 40% acid solution he currently has 20% solution and 50% solution how many liters of each does he need to
Rudiy27
\bf \begin{array}{lccclll}
&amount&concentration&
\begin{array}{llll}
concentration\\
amount
\end{array}\\
&-----&-------&-------\\
\textit{20\% sol'n}&x&0.20&0.20x\\
\textit{50\% sol'n}&y&0.50&0.50y\\
-----&-----&-------&-------\\
mixture&60&0.40&(60)(0.40)
\end{array}

notice above...  we use the decimal format for the percentage, thus 20% is really just 20/100, 40% is 40/100 and so on.

so.. whatever "x" and "y" amounts are, we know they have to add  up to 60 Liters, that is x+y = 60

and whatever the concentration amount of each is, it must add up to (60)(0.40), that is 0.20x+0.50y=(60)(0.40)

thus    \bf \begin{cases}
x+y=60\implies \boxed{y}=60-x\\\\
0.20x+0.50y=(60)(0.40)\\
----------\\
0.20x+0.50\left( \boxed{60-x} \right)=(60)(0.40)
\end{cases}

solve for "x", to see how much of the 20% solution will be needed

what about "y"?  well, y = 60 - x

What kind of shift does the graph have? y = -sin (x-1) from y = sin(x)

\bf \qquad \qquad \qquad \qquad \textit{function transformations}

\left. \qquad  \right. if\ \frac{{{  C}}}{{{  B}}}\textit{ is positive, to the left}\\\\

\bf \bullet \textit{vertical shift by }{{  D}}\\

\left. \qquad  \right. \frac{\pi }{{{  B}}}\ for\ tan(\theta),\ cot(\theta)

now, with that template in mind, let's see

\bf \begin{array}{lllll}
y=&-1sin(&1x&-1)&+0\\
&A&B&C&D
\end{array}
\\\\\\
\textit{horizontal shift of }\cfrac{C}{B}\implies \cfrac{-1}{1}\implies -1
\\\\\\
\textit{A is negative, so is flipped upside-down}

The lines below are parallel. If the slope of the green line is –3, what is the slope of the red line?
Fed [463]
The slope of the red line should be -3 as well since they are parallel lines
