Solve the system of equations graphicallySolution=?

BigorU [14]

The given system is

$\begin{cases}y=\frac{5}{2}x-8 \\ y=-\frac{1}{2}x-2\end{cases}$

Given that y = y, let's combine the equations

$\frac{5}{2}x-8=-\frac{1}{2}x-2$

Let's solve for x

$\begin{gathered} \frac{5}{2}x+\frac{1}{2}x=8-2 \\ \frac{6}{2}x=6 \\ 3x=6 \\ x=\frac{6}{3} \\ x=2 \end{gathered}$

Then, we find y

$y=-\frac{1}{2}x-2=-\frac{1}{2}\cdot2-2=-1-2=-3$

The solution is (2, -3).

The image below shows the solution graphically.

18 13/12 - 8 5/12 =
18 - 8 + 13/12 - 5/12 =
10 + 8/12 =
10 8/12 =

an adult blinks about 450 times in 30 minuets. a twelve year old blinks about 150 times in 15 minuets. how many more times does

Elena-2011 [213]

If an adult blinks 450 times in 30 minutes, then he will blink 900 times in 60 minutes.

A 12-year old blinks 150 times in 15 minutes, so he will blink (150 x 4) in 60 minutes, which comes out to: 600.

so 900-600

An adult blinks 300 times more in 60 minutes than a 12-year old.
