1 ) 9 x + 18 > 9 x - 27
9 x - 9 x > - 27 - 18
0 * x > - 45
Always true
2 ) 6 x - 13 < 9 x - 12
6 x - 6 x < - 12 + 13
0 * x < 1
Always true
3 ) - 6 ( 2 x - 10 ) + 12 x ≤ 180
- 12 x + 60 + 12 x ≤ 180
0 * x ≤ 180 - 60
0 * x ≤ 120
Always true.

Answer:

Step-by-step explanation:

Alright, lets get started.

Lets find slope for both bikes one by one

For bike 1 :

There are two points on the graph of Bike 1, these two points are (2,3) and (4,6)

So the slope for bike 1 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 1 is : $\frac{6-3}{4-2}$

So the slope for bike 1 is : $\frac{3}{2}$

For bike 2 :

There are two points on the graph of Bike 2, these two points are (4,5) and (8,10)

So the slope for bike 2 is : $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

So the slope for bike 2 is : $\frac{10-5}{8-4}=\frac{5}{4}$

Hence Bike 1 will win the race as slope of line bike1 is greater than slope of line bike 2. So, answer is option D

Find the value of in the triangle shown below.

Vesnalui [34]

Step-by-step explanation:

in isoscles triangles two angles and lengths are equal .

two sides equal 3.5

so both of the angles are 55°

the sum of the angles in a triangle is 180°, so

x = 180° - 55° - 55°

x = 70° (Ans)
