Let x be the price of each pen and y be the price of each pencil. From the given, the equations that are described are,
                            6x + 8y = 8.50
                             4x + 4y = 5
Solving for x and y simultaneously gives an answer of x = 0.75 and y = 0.5. 

Thus, each pen costs $0.75 and each pencil costs $0.50.

A line has a slope of 3/2. It passes through the point (4,5). Give the coordinates of three other points on this line
svet-max [94.6K]
Well...The slop is the (Rise/Run) which means (change in y direction / change in x direction)....

Now, imagine if you catch the tip of the line and you move 3 steps in
 y-direction..then you move 2 steps in the x-direction...this is what the slop means....

now the question gives you the point (4,5)=4(x coordinate) & 5(y coordinate)
so draw the x-y axis then
-put the point 4,5 on the graph
-move by the slop value (3 steps in y) then (2 steps in x)
-repeat this 3 times and every time ,record the (x,y) values that you get.

Which expression is equivalent to (5^-2)(5^-1)
nadya68 [22]
The rule for multiplying similar bases with exponents:

(a^b)(a^c)=a^(b+c)

In this case we have:

(5^-2)(5^-1)

5^(-2-1)

5^(-3)

The rule for negative exponents:

a^(-b)=1/(a^b)

So in this case:

5^(-3) is equal to 

1/(5^3)

1/125
