⊕image below!
Which system of equations has a solution of approximately (0.6, –0.8)?
x + 2 y = - 1 and 3 x + y = 1
x - 2 y = 1 and 3 x + y = 1
x -2 y = 1 and 3 x -y = -1
x + 2 y = - 1 and 3 x-y = -1
Answers
Answer:
x + 2 y = - 1 and 3 x + y = 1
Step-by-step explanation:
See the graph attached.
From this graph, it is clear that the green line and the Purple line intersect each other at an approximate point (0.6, -0.8).
Now, the green line passes through the x-intercept (-1,0) and y-intercept (0,-0.5).
Therefore, the equation of the green line will be
⇒ x + 2y = - 1
Therefore, the first combination or the fourth combination will be the answer.
Again, the purple line passes through the point (0,1) and has a negative slope.
So, the equation of purple line will be 3x + y = 1 {Since it has negative slope}
Therefore, the first combination will be the answer.
Answer:
x + 2 y = - 1 and 3 x + y = 1

The molten material before it reaches the surface is called magma.
Before lava reaches the surface, the molten material is referred to as magma. Magma is a mixture of molten rock, dissolved gases, and crystals that is found beneath the Earth's surface within the Earth's crust and upper mantle. It is generated by the melting of solid rock due to high temperatures and/or changes in pressure. Once magma reaches the Earth's surface, it is then called lava. Therefore, the correct answer is b. magma.

Answer:
140 deg
Step-by-step explanation:
The sum of the measures of the interior angles of an n-gon is
(n - 2)180
In a 9-gon, there are 9 sides, so n = 9.
The sum of the measures of the interior angles of a 9-gon is
(n - 2)180 =
= (9 - 2)(180)
= 7(180)
= 1260
A regular polygon has congruent interior angles. A 9-gon has 9 congruent interior angles. The measure of each interior angle is the sum of the measures of the interior angles divided by the number of angles.
1260/9 = 140
