The answe is on the link i put below it’s a file! hopefully it helps
the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
to calculate m use the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 1) and (x₂, y₂) = (1 1/2, 2 )
m = = =
using (a, b) = (- 4, - 1), then
y + 1 = (x + 4)
All of the obtuse angles in your problem is 150 degrees. So if x is an obtuse angle you also get 150 degrees. All the acute angles are 30 degrees.
Answer:
x ≤ 4.9
Step-by-step explanation:
5x +1/2≤ 25
Multiply each side by 2 to get rid of the fractions
2(5x +1/2)≤ 25*2
10x +1 ≤ 50
Subtract 1 from each side
10x+1-1 ≤50-1
10x ≤ 49
Divide by 10 on each side
10x/10 ≤ 49/10
x ≤ 4.9
