The answer is 3.1 because 4 is under 5
-7+3x+7x = 7x+5
10x-7 = 7x+5
-7x -7x
3x-7 = 5
+7 +7
3x = 12
x=4
Answer:
D) 82 units
Step-by-step explanation:
ΔBCD ≅ ΔEFG
In congruent triangles, corresponding parts are congruent
BD = EG
4x - 9 = 2x + 15
4x - 9 -2x = 15
2x - 9 = 15
2x = 15 +9
2x = 24
x = 24/2
x = 12
EG = 2x + 15 = 2*12 + 15
= 24 + 15
EG = 39 units
FE = CB = 17 units
Perimeter of ΔEFG = FE + EG + GF
= 17 + 39 + 26
= 82 units
Answer:
Step-by-step explanation:
Given: graph
To find:the inequality
Solution:
Equation of a line passing through points 
is given by 
Take 
So,equation of line is evaluated as follows:
As per the graph,inequality is
Here, use sign < and not 
as line in the graph is dotted that is points on the line are excluded.
