Answer:

=−24a−6

Step-by-step explanation:

Let's simplify step-by-step.

−3a−3(7a+2)

Distribute:

=−3a+(−3)(7a)+(−3)(2)

=−3a+−21a+−6

Combine Like Terms:

=−3a+−21a+−6

=(−3a+−21a)+(−6)

=−24a+−6

Examine the following system of inequalities.

Answer:

Dotted linear inequality shaded above passes through (0, 4) and (4, 0). Solid exponential inequality shaded below passes through (negative 2,2) & (0,5)

Step-by-step explanation:

we have

$y > -x+4$ ----> inequality A

The solution of the inequality A is the shaded area above the dotted line $y=-x+4$

The dotted line passes through the points (0,4) and (4,0) (y and x-intercepts)

and

$y \leq -(1/2)^{x} +6$ -----> inequality B

The solution of the inequality B is the shaded area above the solid line $y=-(1/2)^{x} +6$

The solid line passes through the points (0,5) and (-2,2)

therefore

The solution of the system of inequalities is the shaded area between the dotted line and the solid line

see the attached figure
