I need help on these questions it’s a part of a common assessment.

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

      -7    -7

2x = 8

divide by 2 to isolate x

x = 4

2nd pic) y - 3 <= 6

y - 3 <= 6

  +3      +3

y <= 9

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

   -0.5         -0.5

x = x + 5.5

NO SOLUTION

4th pic)  5m + 10 <= 130

5m + 10 <= 130

      -10        -10

5m <= 120

divide by 5 to isolate the m

m <= 24

5th pic) 2c - 8 > 0

2c - 8 > 0

     +8   +8

2c > 8

divide by 2 to isolate the c

c > 4

12*c

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
