Answer:

16 yellow flowers

Step-by-step explanation:

Pink: yellow\\6\:\::\:2\\\\Total\:ratio = 6+2 = 8\\\\48 \:pink\: flowers

First calculate total no of flowers

\frac{6}{8} \times x = 48\\\\\frac{6x}{8} =48\\\\Cross\:Multiply\\6x = 48\times 8\\6x = 384\\\\Divide\:both\:sides\:of\:the\:equation\:by\:6\\\frac{6x}{6} = \frac{384}{6} \\\\x = 64\\\\Total \:flowers = 64

Calculate no of yellow flowers

Total\:flowers-Pink\:flowers = Yellow\:flowers\\\\Yellow\:flowers = 64 - 48\\Yellow\:flowers =16

\bf \begin{array}{lccclll}
&\stackrel{lb}{amount}&\stackrel{lb}{price}&\stackrel{total}{price}\\
&------&------&------\\
\textit{plain popcorn}&p&3&3p\\
\textit{caramel popcorn}&c&2.2&2.2c\\
-------&------&------&------\\
mixture&10&2.5&25
\end{array}

so hmm whatever "p" and "c" are, we know that p + c = 10.

and we also know that 3p + 2.2c = 25

thus

\bf \begin{cases}
p+c=10\implies \boxed{c}=10-p\\
3p+2.2c=25\\
----------\\
3p+2.2\left(\boxed{10-p}  \right)=25
\end{cases}
\\\\\\
3p+22-2.2p=25\implies 3p-2.2p=25-22\implies 0.8p=3
\\\\\\
p=\cfrac{3}{0.8}\implies p=\cfrac{15}{4}\implies p=3.75

how much will it be needed for caramel popcorn?  well, c = 10 - p.

How do I solve this do we use the multiple choice
belka [17]

Answer:

  (C)  4|5 -2x| > 68

Step-by-step explanation:

You can solve each of the inequalities to see if their solutions match the given numbers, or you can start with the given numbers and see what sort of inequality you end up with.

If you plot the given "solution" on a number line, you find that the numbers -6 and 11 are the same distance from x=2.5. That distance is 8.5 units. (One way to deterimine this is to average -6 and 11, then subtract that average from 11 to find the distance.

So, we can write an inequality describing values of x that are more than 8.5 units from 2.5:

  |x -2.5| > 8.5

and it will have the solution x < -6 or x > 11.

Multiplying this by 2, it can become ...

   |2x -5| > 17

Of course, since the absolute value function doesn't care whether its argument is positive or negative, we can also write this as ...

   |5 -2x| > 17

This tells you right away which answer choice is appropriate. Further confirmation can be had by multiplying this by 4:

  4|5 -2x| > 68 . . . . . . matches selection C

Which statement best describes the effect of replacing the function f(x) = 2x − 2 with the function g(x) = 2x + 5?
umka21 [38]
<h2>Answer:</h2>

The  statement which best describes the effect of replacing the function f(x) with g(x) is:

               The graph shifts 7 units up.

<h2>Step-by-step explanation:</h2>

The function f(x) is given by :

f(x)=2x-2

The function f(x) is a linear function with positive slope.

and the function g(x) is given by:

g(x)=2x+5

The function g(x) is a linear function with same positive slope.

Also, we know that any transformation of the type:

f(x) → f(x)+k

is a translation transformation such that it if k>0 then it is a shift k units upwards and if k<0 then it is a shift k units downward.

Here we have:

g(x)=2x+5-2+2

i.e.

g(x)=2x-2+7

i.e.

g(x)=f(x)+7

Hence, the function g(x) is a translation of the function f(x) 7 units upward.

Every point is translated according to the rule ( x, y ) → ( x + 2, y - 6 )
L ( -1, 2 ) → L´ ( -1 + 2,  2 - 6 ) = ( 1, -4 )
