The graph of f(x)=x2 is shown. Use the parabola tool to graph the function g(x)=(12x)2. To graph a parabola, first plot the vert
Talja [164]

Answer:

Pease check my assumptions.

Step-by-step explanation:

I will assume that f(x)=x2 is actually f(x) = x^2.

Same for g(x)=(12x)^2  [Is it g(x)=12x^2  ???]

See the attached image.

Note that (12x)^2 results in a narrower, steeper graph.   That's because (12x)^2 can be rewritten as 144x^2, so every value is multiplied by 144, compared to just x^2.

A collection of quarters and dimes is worth $12.40. There are 67 coins in all.
padilas [110]
Let:
x= quarters
y= dimes


x+y=67
and
.25x+.10y=12.40

x=67-y

.25(67-y)+.10y=12.40
16.75-.25y+10y=12.40
16.75-.15y=12.40
Lets rearrange this:
-.15y+16.75=12.40
        -16.75    -16.75
-.15y=-4.35
the negatives cancel out
.<u>15y</u>=<u>4.35
</u>.15<em /><em>     <u /></em>.15
y=29

Back to the original x=67-y
x=67-29
x=38

So,
x=38
y=29
