just like the previous one, we sum the sides to get the perimeter.

1/5 (or 20%) of $1,200 is $240
$1,200 - $240 = $960
The cost of a $1,200 washing machine after a discount of 1/5 (20%) is $960
Answer:
x >_ 1
Step-by-step explanation:
Solving an inequality is a lot like solving an equation. Just pretend the inequality symbol is an equal sign!
(also i wont be using the _ or equal to symbol because I'm too lazy, so you'll get >_ or <_ for those, sorry)
8 + 4x >_ 12
-8 -8
4x >_ 4
/4 /4
x >_ 1
I think it's the second one on the top, because the dotted one is actually inside the bigger one and you can get a clear representation of the sizes.
Answer:
The V-shaped graph opens downward, and its vertex lies at (1, 12).
Step-by-step explanation:
- first, plot the graph of f(x),
- take some 5 random negative and positive x values and then find corresponding f[x] values.plot f(x) on y-axis. now, plot these points on the graph and finally join all the points. this gives u the required graph.
- I have plotted the graph and uploaded it.
refer it.
- by seeing the graph, we can easily say that,The V-shaped graph opens downward, and its vertex lies at (1, 12).
