<span>A parallelogram can be divided into two congruent triapezoids. The area of each trapezoid is one-half the area of the parallelogram. The two parallel sides of atrapezoid are its bases. If we call the longer side b1 and the shorter side b2, then the base of the parallelogram is b1+b2</span>

A bottle of water costs $1.50. Explain how you would make a graph of four ordered pairs to model the total cost of the water in

Vanyuwa [196]

Total cost = 1.50 per bottle
y = 1.50x
If x = 1, y = $ 1.50 (1,1.5)
If x = 2, y = $ 3.00 (2,3)
If x = 3, y = $ 4.50 (3, 4.5)
If x = 4, y = $ 6.00 (4, 6)
There are your 4 sets of ordered pairs to graph.
You could continue with more x-values to get more ordered pairs.

A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 40% off clearan

Hatshy [7]

Answer: He would pay 45% of the original price.

Step-by-step explanation:

Since we have given that

Let the original price of item be 'x'

Rate mark down by 25%

Amount of marked down would be

$\dfrac{25}{100}\times x\\\\=0.25x$

Amount after marked down becomes

$x-0.25x\\\\=0.75x$

Additional clearance items by 40% off

Amount of additional off is given by

$\dfrac{40}{100}\times 0.75x\\\\=0.4\times 0.75x\\\\=0.3x$

After additional off, the amount becomes,

$0.75x-0.3x\\\\=0.45x$

Hence, he would pay 45% of the original price.

What are the zeros of the function y = x2 + 10x – 171, and why?

vagabundo [1.1K]

To find the zeros, you have to factor the equation.
y=(x+19)(x-9)
This is because 19*-9=-171 and 19-9=10.
Now to make x=0, you have to make the equation
x+19=0
and x-9=0
To solve, isolate x on both equations.
This makes x=-19 and x=9.
