Write in 0 and 0 at the top:  this indicates that if there are zero pennies, the height of the tower is 0.  This is the point (0,0).  Another point is (4, 28):  a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
            4cm - 0 cm
    m = ----------------- = (1/7) (cm/penny)
            28 - 0

The equation we need, relating # of pennies to height of tower, is 

       t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.

A function has x-intercept 3 and y-intercept 2. Which of the functions below could be this function?
Sergeeva-Olga [200]

we are given

x-intercept is 3

so,

a=3

y-intercept is 2

b=2

now, we can intercept formula of line

\frac{x}{a} +\frac{y}{b}=1

now, we can plug

a=3 and b=2

\frac{x}{3} +\frac{y}{2}=1

now, we will get rid of denominators

so, we can multiply both sides by 6

6*\frac{x}{3} +6*\frac{y}{2}=6*1

2x +3y=6

we can also write it as

3y-6=-2x

so, option-D..................Answer

a sign for a museum is shaped like a parallelogram. the base of the sign is 20 feet, and the area is 500 square feet. what is th
Lina20 [59]
Since 500 is the area, and 20 is the length, divide 500 by 20. Your answer is a decimal. (0.04) therefore, you have to make it into a whole number. So move the decimal to the right two times. So 4 is your height.
