Answer:

The graph in the attached figure

The point  (-1,4)  represent a solution

Step-by-step explanation:

we have

x> -2----> inequality A

y\leq 2x+7 ----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities

The point  (-1,4)  represent a solution

If y varies directly as x and z and y=4 when x=6 and z=1 find y when x=7 and z=4
yawa3891 [41]

<u>Answer-</u>

<em>The value of y is \dfrac{56}{3} when x=7 and z=4.</em>

<u>Solution-</u>

As given in the question, y is directly proportional to x, so

y\propto x   -----------------1

And also y is directly proportional to z, so

y\propto z   -----------------2

Combining equation 1 and 2,

\Rightarrow y\propto x.z

\Rightarrow y=k.x.z

Where,

k = proportionality constant

When x=6 and z=1, y=4. Putting theses values,

\Rightarrow 4=k\times 6\times 1

\Rightarrow 4=6k

\Rightarrow k=\dfrac{4}{6}

\Rightarrow k=\dfrac{2}{3}

Now, we have to find the value of y, when x=7 and z=4

\Rightarrow y=\dfrac{2}{3}\times 7\times 4

\Rightarrow y=\dfrac{56}{3}

Therefore, the value of y is \dfrac{56}{3} when x=7 and z=4.
