\bf \begin{array}{lccclll}
&\stackrel{lbs}{amount}&\stackrel{unit}{cost}&\stackrel{total}{value}\\
&------&------&------\\
Raisins&11&2.30&25.3\\
Peanuts&p&4.50&4.5p\\
------&------&------&------\\
mixture&m&3.29&3.29m
\end{array}

we know that, the mixture amount is the sum of 11 + p, or 11 + p = m.

we also know that, the total value is also a sum of 25.3 + 4.5p = 3.29m.

\bf \begin{cases}
11+p=\boxed{m}\\
25.3+4.5p=3.29m\\
----------\\
25.3+4.5p=3.29\left( \boxed{11+p} \right)
\end{cases}
\\\\\\
25.3+4.5p=36.19+3.29p\implies 1.21p=10.89\implies p=\cfrac{10.89}{1.21}
\\\\\\
p=\stackrel{lbs}{9}

Write the word sentence as an inequality, 3 less than a number t is at most 7
AlexFokin [52]
"3 less than a number t is at most 7"

"3 less than a number t" --> t - 3
"is at most" --> \leq
"7" --> 7

put this together and we get:
t - 3 \leq 7

Help me find the answer to this piecewise problem!! 20 Points !!!!
MrRissso [65]

Answer:

So we have x+3 if -3<=x<=-1

and                5   if   -1<=x<=1

Step-by-step explanation:

The one piece from -1 to 1 is horizontal so the line is in the form of y=a number.  It goes through 5 on the y-axis so the equation there is y=5.

From -3 to -1, that is a line with positive slope (since that part is increasing).

Slope=rise/run

We see from the filled in dot to the unfilled in dot that the rise is 2 and the run is 2 so the slope is 2/2=1.

So if we did extend this line where we go at on the y-axis?  It would go through 3 because starting from the unfilled dot and rising 1 and running 1 will get us to the 3 on the y-axis.

The equation of a line in slope-intercept form is y=mx+b.

We have m=1 and b=3 so the equation is y=1x+3 or just y=x+3.

So we have x+3 if -3<=x<=-1

and                5   if   -1<=x<=1
