Answer:

No solution, D

Step-by-step explanation:

If you rewrite the second one to be the y=mx+b form then you get

8x-14= -2y

Divide by -2 and get

-4x+7=y

Because the slopes are the same the lines will never intersect which means there is no solution

2x – 5 > 3 or 11 – 3x > -2

IRISSAK [1]

Answer:

x > 4 and x <3

Step-by-step explanation:

Given the system of inequalities

2x – 5 > 3 or 11 – 3x > -2

for 2x – 5 > 3

2x > 3+5

2x>8

x>8/2

x> 4

For 11-3x > -2

-3x > 2-11

-3x > -9

x < -9/-3

x<3

hence the result will be x > 4 and x <3

An air-filled rubber ball has a diameter of 6 in. If the air pressure within the ball is increased until the diameter becomes 7

Yakvenalex [24]

we are given

An air-filled rubber ball

$d_0=6in$

$d=7in$

we can use formula of the average normal strain in the rubber

$\delta =\frac{\pi d - \pi d_0}{\pi d_0}$

now, we can plug values

and we get

$\delta =\frac{\pi*7 - \pi*6}{\pi* 6}$

$\delta =0.16667in/in$ ...........Answer
