y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5

y=4^x

OK, we'll go in steps.  First a reflection through the x axis, which negates y.

y = -4^x

Now a vertical scaling of 2/3

y = -\frac 2 3 \cdot 4^x

Now we shift seven units to the right,

y = -\frac 2 3 \cdot 4^{x+7}

Now down five,

y = -\frac 2 3 \cdot 4^{x+7} - 5

There it is.

Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice

How do I graph this?​
vfiekz [6]

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48

<h3>How to graph the inequalities?</h3>

The inequalities are given as:

x + 7y ≤ 49

6x + y ≤ 48

The domain and the range are:

x ≥ 0

y ≥ 0

This means that, we plot the inequalities x + 7y ≤ 49 and 6x + y ≤ 48 under the domain and the range x ≥ 0 and y ≥ 0

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48
