Answer:


Step-by-step explanation:

I take it that the question is What is the value of x.

... Every triangle has a measure of 180o so that is what is on the right side of the equation.

... the Vertex of an isosceles triangle has a unique value. There is only one angle with a measure of 42.

... The Base angles are equal. And there are 2 of them.

Equation

2x + 3 + 2x + 3 + 42 = 180o      

Solution

Combine like terms

2x + 2x + 3 + 3 + 42 = 180  Show the like terms as 1 term for the xs and 1 for the pure numbers on the left.

4x + 48 = 180   Subtract 48 from both sides

4x = 180 - 48    combine

4x = 132            Divide by 4

4x/4 = 132/4

x = 33

Answer

x = 33

2x + 3 = 2*33 + 3 = 69

So the three angles are

69 + 69 + 42

Check

69 + 69 + 42

138 + 42

180 as it should.

Please help answer this

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.
