Just add all the sides - as it's a rectangle the opposite sides are the same. Also i think you mixed up the length with the width of the rectangle.

The point-slope form:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - the point

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (5, 4) and (2, -2). Substitute:

$m=\dfrac{-2-4}{2-5}=\dfrac{-6}{-3}=2$

$y-4=2(x-5)$ - point-slope form

$y-4=2x-10$ add 4 to both sides

$y=2x-6$ - slope-intercept form

$y=2x-6$ subtract 2x from both sides

$-2x+y=-6$ change the signs

$2x-y=6$ - standard form

-------------------------------------------------------------------

From the table we have two points (1, 3) and (2, 7). SubstituteL

$m=\dfrac{7-3}{2-1}=\dfrac{4}{1}=4$

$y-3=4(x-1)$ - point-slope form

$y-3=4x-4$ add 3 to both sides

$y=4x-1$ - slope-intercept form

$y=4x-1$ subtract 4x from both sides

$-4x+y=-1$ change the signs

$4x-y=1$ - standard form

Jason has $0.37 worth of pennies and nickels. He has a total of 13 pennies and nickels altogether. Determine the number of penni

fredd [130]

Answer: Jason has 7 pennies and 6 nickels.

Step-by-step explanation:

Let be "p" the number of pennies that Jason has and "n" the number of nickels that Jason has.

Set up a system of equations:

$\left \{ {p+n=13} \atop {0.01p+0.05n=0.37}} \right.$

You can use the Elimination Method. Multiply the first equation by -0.01 and add both equations:

$\left \{ {-0.01p-0.01n=-0.13} \atop {0.01p+0.05n=0.37 }} \right.\\................................\\0.04n=0.24\\\\n=6$

Susbtitute this value into the first equation and solve for "p":

$p+6=13\\\\p=13-6\\\\p=7$
