Write an expression to represent four more than the problem of three and a number z
kicyunya [14]

Answer:

If the "problem of 3 and a number z" is multiplying: 4+(3z)

If it's about adding: 4+(3+z)

Step-by-step explanation:

Scenario A: If it's 3 and z, then that means it's 3z, and we're adding 4, so it's 4+(3z) (make sure to put () around the 3z!)

Scenario B: If 3 and z is also 3+z, then the equation is 4+(3+z) (also use () on this too!)

Please help answer this
saul85 [17]

Answer:

Option D.

Step-by-step explanation:

The given inequality is y\le -2x-2.

To graph this inequality, we need to graph the corresponding linear equation;

y=-2x-2

The intercepts are (0,-2) and (-1,0).

Plot these two points and draw a solid straight line through them.

We then test the inequality with the point (0,0).

0\le -2(0)-2.

0\le -2.

This statement is false.

So we shade the lower half plane to obtain the graph in option D.
