If rs =3x + 1, st = 2x- 2 ,and rt = 64,find the value of x
stealth61 [152]
             rs + st = rt     Plug in the values
3x + 1 + 2x - 2 = 64   Combine like terms (1 and -2)
       3x -1 + 2x = 64   Combine like terms (3x and 2x)
            -1 + 5x = 64   Add 1 to both sides
                  5x = 65   Divide both sides by 5
                    x = 13

A parking meter gives 30 minutes for each quarter and 6 minutes for each nickel
aleksley [76]

Answer:

B as we start with X intercept =0

Step-by-step explanation:

x= 10 x 6 = 60

(v= 1/6x = 6x x 10y) x= 60v

y=10

When x=0 then y = 0 when x= 10 we have 10 minutes each count

So the graph will go up by 10 to 60 on the x axis.

value of nickle=6  and units of 10 nickles have value of 60

But this is a measure of time using nickles for x.

and measure of quarters can then show a pattern of zero each time. y=mc+x = 0 when y=0 =  y=1x0+0 when x =6 and y=0

If the two lines below are perpendicular and the slope ofthe red line is -, what is the slope of the green line?51015-5-5-105
inysia [295]

If two lines are perpendicular, then the product of their slopes is -1:

m_r\cdot m_g=-1...(1)

From the problem, we identify:

m_r=-\frac{4}{3}\text{  \lparen the slope of the red line\rparen}

Then, using the equation (1), we calculate the slope of the green line:

\begin{gathered} -\frac{4}{3}\cdot m_g=-1 \\  \\ \therefore m_g=\frac{3}{4} \end{gathered}
