Answer:
Domain should be [-4, 5] if that is what the second x variable is.
Range should be [3, -5]
yes with brackets because it is closed

Answer:
Correct answer: m∠A = 52°
Step-by-step explanation:
Given:
m∠A = 9 x - 2 = ?
m∠B = 16 x
m∠C = 5 x + 2
The sum of the inner angles in a triangle is 180 degrees
m∠A + m∠B + m∠C = 180°
9 x - 2 + 16 x + 5 x + 2 = 180
30 · x = 180
x = 180 / 30 = 6°
x =6°
m∠A = 9 x - 2 = 9 · 6 - 2 = 54 - 2 = 52°
m∠A = 52°

answer:
-1
work:
y = mx+ b
so we can tell that the Y intercept is 1, so we can plug that in. ( + b is the y-intercept)
y = mx + 1
plug in some values to find the slope.
(-1, 2)
2 = -m + 1
- 1 - 1
1 = -1m
/-1 /-1
-1 = m
the slope is -1.
i hope this helps! :D
Answer:
r = 19.0
s = 17.7
Step-by-step explanation:
In the given right triangle ABC,
Measure of Hypotenuse (AC) = 26
m(∠CAB) = 43°
By applying sine rule in the given triangle,
sin(43)° = 
sin(43)° = 
s = 26[sin(43)°]
s = 17.73
s ≈ 17.7
Similarly, by applying cosine rule in the given triangle,
cos(43)° = 
= 
r = 26[cos(43)°]
r = 19.02
r ≈`19.0
9/10 is greater than 11/15
