Answer:
[-11/5,∞)
Step-by-step explanation:
1. Add 4 to both sides: 7x-4+4≥-15+2x+4
2. Simplify: 7x≥2x-11
3. Subtract 2x from both sides: 7x-2x≥2x-11-2x
4. Simplify: 5x≥-11
5. Divide both sides by 5: 5x/5≥-11/5
6. Simplify: -11/5
Answer:
y = 2/3x-8
Step-by-step explanation:
in the equation y = mx+b, m = slope and b = y-intercept. all you have to do is plug the numbers in!!
3 + 5 = 8
8 - 5 = 3
3 - 3 = 0
Supplementary angles: sum of the angles measure to be 180º
180º-A= B
Plug in...
180º-80º= 100º
So, angle B must be 100 degrees.
Answer:
x+3
Step-by-step explanation:
sqrt(x^2+6x+9)
factor
We know this is a perfect square trinomial
sqrt(( x+3)^2)
Taking the square root of a square
x+3
