Answer:
<em>40°, 60°, 80°</em>
Step-by-step explanation:
Answer:
The equation is:
f(x) = Ix + 3I - 2
Step-by-step explanation:
For a function like:
f(x) = Ix - kI + c
k is the x-value where the vertex is, and c is the y-value where the vertex is.
In the graph we can see that the vertex is in the point (-3, -2)
then:
x-value = -3 = k
y-value = -2 = c
Replacing those in the equation for the function:
f(x) = Ix - (-3)I - 2
f(x) = Ix + 3I - 2
Answer:
-31/9
Step-by-step explanation:
Bring -5/9 to other side
-4 is also written as -3 9/9
-3 9/9 + 5/9 = x
-3 4/9 = x
