Which is the domain of the function shown in the graph?
A. x ≤ 3
B. -∞ < x < ∞ ( ✔ )
C. x > 0
D. x ≥ 3
The answer is 9.3 or 9 over 3 meaning going up 9 and over 3 leaving this to be an isosceles acute triangle
Answer:
x = 106
Step-by-step explanation:
The angle with a measure of 106 degrees and the angle labeled "x" are opposite exterior angles
Opposite exterior angles are congruent
Hence, x = 106
Since both equations are solved for y, use substitution.
y = 2x + 3
y = -x - 5
2x + 3 = -x - 5
3x + 3 = -5
3x = -8
x = -8/3
Now substitute -8/3 in for x in the original first equation, and solve for y.
y = 2x + 3
y = 2(-8/3) + 3
y = -16/3 + 9/3
y = -7/3
Solution: (-8/3, -7/3)
