Solve plzz
x − 1 ≤ 6

(a)x ≤ 5;

(b)x ≤ 7;

(c)x ≥ 7;

(d)x ≤ 7;

(D)x ≤ 7

Step-by-step explanation:

x − 1 ≤ 6

Add 1 to each side

x − 1+1 ≤ 6+1

x  ≤ 7

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
