A. The master bolt was stolen.
Answer:
y= 7
Step-by-step explanation:
3y+7=28
subtract 7 from both sides
3y=21
divide each side by 3
y/3=21/3
y=7
Answer:
As the number of sides increases, the measures of the angles increase
see the explanation
Step-by-step explanation:
we know that
The measure of the interior angle in a regular polygon is equal to

where
n is the number of sides of the regular polygon
x is the measure of the interior angle in a regular polygon
we have that
<u><em>Examples</em></u>
<em>A triangle</em>
n=3 sides

<em>A square</em>
n=4 sides

<em>A pentagon</em>
n=5 sides

<em>A hexagon</em>
n=6 sides

so
n ----> 3,4,5,6...
x ----> 60°,90°,108°,120°,...
As the number of sides increases, the measures of the angles increase
The pattern is 
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x - 2y = - 3 into this form
Subtract x from both sides
- 2y = - x - 3 ( divide all terms by - 2 )
y =
x +
← in slope- intercept form
with m = 
• Parallel lines have equal slopes, thus
y =
x + c ← is the partial equation
To find c substitute (- 1, 2) into the partial equation
2 = -
+ c ⇒ c = 2 +
= 
y =
x +
← in slope- intercept form
Multiply through by 2
2y = x + 5 ( subtract 2y from both sides )
0 = x - 2y + 5 ( subtract 5 from both sides )
- 5 = x - 2y, thus
x - 2y = - 5 ← in standard form
