Answer:
A.
Step-by-step explanation:
If x=5
5 + 10 is less than 25.
If x=15
15+10 is equal to 25
If x =20
20+10 is greater than 25
This inequality has NO SOLUTION:
PROOF:
3x + 1 < 2x - 2 < 5x +7
1st let's analyze the 1st inequality: 3x+1<2x-2
3x-2x <-2-1 Then x <-3
2nd let's analyze the 2nd inequality: 2x-2 < 5x+7
2x-5x < 7+2 Then -3x<9 OR 3x > - 9 and x> - 3
In the 1st we have x <-3 in the 2nd we have x > - 3 which is impossible

14/10 = 1.4 (10 %)
1.4/2= 0.7 (5%)
1.4 + 0.7 = 2.1 (15%)
14 - 2.1 = $11.9
Step-by-step explanation:
y + 2 = 1/4(x - 8)
y +2 =1/4x - 2
y = 1/4x - 4
