Answer:

the answer is -5/2

Step-by-step explanation:

go down 5 and over 2 till you get to the point if you go down to the y val you will get ten and the x will be 4 and y goes on top so -10/4= -5/2

2a + 4b + c =5 x =-2 a - 4b = -6 y=1

cricket20 [7]

There is no solution ,a+c=-10;b-c=15;a-2b+c=-5 No solution System of Linear Equations entered : [1] 2a+c=-10 [2] b-c=15 [3] a-2b+c=-5 Equations Simplified or Rearranged : [1] 2a + c = -10 [2] - c + b = 15 [3] a + c - 2b = -5 Solve by Substitution :

// Solve equation [3] for the variable c

[3] c = -a + 2b - 5

// Plug this in for variable c in equation [1]

[1] 2a + (-a +2?-5) = -10 [1] a = -5

// Plug this in for variable c in equation [2]

[2] - (-? +2b-5) + b = 15 [2] - b = 10

// Solve equation [2] for the variable ?

[2] ? = b + 10

// Plug this in for variable ? in equation [1]

[1] (? +10) = -5 [1] 0 = -15 => NO solution No solution

Es The measure of an interior angle of a regular polygon is 120°. What is the measurb of each exterior angle? The polygon has

Troyanec [42]

The measure of each exterior angle is 60° and the polygon has 6 sides ⇒ 4th answer

Step-by-step explanation:

In a regular n-side polygon:

All sides are equal in lengths
All angles are equal in measure
The measure of each interior angle = $\frac{(n-2)*180}{n}$
The measure of each exterior angle = $\frac{360}{n}$
The sum of interior angle and exterior angle at a vertex is 180°

∵ The measure of an interior angle of a regular polygon is 120°

∵ The sum of interior angle and exterior angle at a vertex = 180°

∴ The measure of each exterior angle = 180 - 120

∴ The measure of each exterior angle = 60°

∵ The measure of each exterior angle = $\frac{360}{n}$

- Substitute the measure of the exterior angle by 60

∴ $60=\frac{360}{n}$

- By using cross multiplication

∴ 60 n = 360

- Divide both sides by 60

∴ n = 6

∴ The polygon has 6 sides

The measure of each exterior angle is 60° and the polygon has 6 sides

How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18 2

Elena L [17]

Answer:

$4x + 20 - 5 = 0 \\ 4x + 15 = 0 \\ 4x = - 15 \\ x = - \frac{15}{4}$

Step-by-step explanation:

$8x + 18 = 0 \\ 8x = - 18 \\ x = - \frac{18}{8} \\ x = - \frac{9}{4}$
