Answer:
- (-3, 5), (4, 1), (-1, -5)
Step-by-step explanation:
270° counterclockwise rotation is same as 90° clockwise
<u>The rule is:</u>
<u>Given points:</u>
- A(-5, -3), B(-1, 4), C(5, -1)
<u>Translated points:</u>
- A' = (-3, 5)
- B' = (4, 1)
- C' = (-1, -5)
We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B. Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7. We can get B on its own by making the equation this:
Now, we plug this into our calculator to get:
B = 55°, so angle B is 55°.

Answer:
18/5
Step-by-step explanation:
Answer:
Domain is { x> -15}
Range is { y >5}
Step-by-step explanation:
The domain is the possible x values
x is greater than -15 (open circle)
Domain is { x ≥ -15}
The range is the possible y values
y is greater than 5 (open circle)
Range is { y >5}
X=7/3 and x=7/2
if you want the step-by-step then you just try to isolate x and it is pretty self-explanatory from there on. Hope this helped!
:P
