Answer:
C) x – 2). 2 ... -2x ≤ 2. ⇔ x ≥ -1. Tập nghiệm S = {x | x ≥ -1}. Bài 2. Gọi x (km) là quãng đường
Step-by-step explanation:
1) If <span>2x > 50 , then x > 25. Draw a circle at x=25 and then extend a ray in the positive x direction away from x = 25.
2) If x + 6 < 32, subtract 6 from both sides, obtaining x < 26.
Draw a cirlce at x=26 and extend a ray from that x to the left.</span>
F = 4
if f(x)=11, you must always try and get x alone, so f = (11+5)/4, and this simplifies to 4.
Answer:
Simplifying
9x + 7 = 5x + -3
Reorder the terms:
7 + 9x = 5x + -3
Reorder the terms:
7 + 9x = -3 + 5x
Solving
7 + 9x = -3 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
7 + 9x + -5x = -3 + 5x + -5x
Combine like terms: 9x + -5x = 4x
7 + 4x = -3 + 5x + -5x
Combine like terms: 5x + -5x = 0
7 + 4x = -3 + 0
7 + 4x = -3
Add '-7' to each side of the equation.
7 + -7 + 4x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + 4x = -3 + -7
4x = -3 + -7
Combine like terms: -3 + -7 = -10
4x = -10
Divide each side by '4'.
x = -2.5
Simplifying
x = -2.5
make me brainiest plz!!!
Step-by-step explanation:
Answer:
7/6
It's 7/6 because 6/6 make up a whole which is the 1 in 1 1/6
then there is that left over 1/6 to make it 7/6
