Answer:
10/13 ≤ x < 18/13
Step-by-step explanation:
-1 ≤ 13x - 11 < 7
If a ≤ u < b then a ≤ u and u < b
⇒ -1 ≤ 13x - 11 and 13x - 11 < 7
-1 ≤ 13x - 11
Add 11 to both sides: 10 ≤ 13x
Divide both sides by 13: 10/13 ≤ x
13x - 11 < 7
Add 11 to both sides: 13x < 18
Divide both sides by 13: x < 18/13
Combine the intervals
10/13 ≤ x < 18/13
Answer:
x=70
Step-by-step explanation:
angles of a triangle are always 180
180-40=140
140=2x
divide both sides by 2
70=x
Answer:
parallel = same slope (-2x)
so it's y=-2x + b
let's find b by plugging in 1 for x and 3 for y (the coordinates)
3 = -2*1 + b
3 = -2 + b
5 = b
there you have it:
y = -2x +5
brainliest would really be appropriated (possible when someone else also leaves an answer)
x = 18
The value "18" from the data set makes the equation true.
x + ( x + 1 ) + ( x + 2 ) = 57
18 + ( 18 + 1 ) + ( 18 + 2 ) = 57
18 + 19 + 20 = 57
57 = 57
