Answer:
The answer is C
Step-by-step explanation:
OK, so you know the equation y = mx + b?
To find the slope, divide rise/run
Since the line is going down, that means the slope is negative.
See which y has x = 0
In this case it’s -1
so it has to be C
Answer:
B. AA similarity postulate
You have two crossed lines. They form a total of 4 angles. The x and 78 are straight across from each other. When that happens, the two angles are labeled as vertically opposite angles.
Vertically opposite angles are always equal
x = 78 <<<<<<<< answer
When f(x) = 4 then x = 2 (domain = 2, range = 4)
hope it helps
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
