Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° <em>- equation</em>
7x-1 + 7x+8 + 5x+2 = 180° <em>- "distribute"</em>
19x - 1 + 8 + 2 = 180°<em> - combine the x terms</em>
19x + 9 = 180° <em>- combine the integer terms</em>
19x = 171 <em>- subtract 9 form both sides</em>
x = 9 <em>- divide both sides by 19</em>
Answer:
c) y= -3x + 3
Step-by-step explanation:
Given equation
y= 1/3x+6
Here slope m1 = 1/3
We know that the slope of perpendicular lines
m1*m2 = -1
slope of perpendicular line m2 = -1/m1
= -1/ (1/3)
m2 = -3
Also the line passes through (2, -3)
equation of line is given by y = mx+b
y= -3
x= 2
m2 = -3
Applying above values to the equation of line,
-3 = (-3*2)+b
b=3
Hence equation of perpendicular line is y = -3x + 3
Answer:
This is so easy
Let me explain:
first lets find out (f+g)(x)=-x+3x+5+x^2+2x=
x^2+4x+5 this is the equation of a parabola because we have x^2
so only the first graph shows us a parabola
which remains the right one.
