Answer: m<DCB= 50 degrees
Step-by-step explanation:
120= (15x+5)+(22x+4)
120= 37x+9
111= 37x
x=3
15(3)+5
45+5=
50
Ronald’s monthly income = $100,482/12 = $8373.50
Don’t know what the second question is asking
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

----> equation A
This is the equation of a vertical parabola open downward
The vertex is the point (0,7)

----> equation B
This is the equation of a circle with center at (0,0) and radius equal to 7 units
The y-intercepts of the circle are the points (0,7) and (0,-7)
therefore
The graph in the attached figure
You would first subtract 5*8 from 168 which would leave it at 128 then divided it by 8 and then you'll end up with 16 so each tree cost 16$
By evaluating the linear function in x = 7 we conclude that:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>
<h3>
</h3><h3>
Which statement about f(7) is true?</h3>
Here we have the linear function f(x)= 10 - 0.5*x, it represents the amount of money remaining after x songs are played on the jukebox.
Then, that function evaluated in 7 is:
f(7) = 10 - 0.5*7 = 10 - 3.5 = 6.5
This means that after you play 7 songs, the amount of money remaining is $6.5
From this we can see that the correct option is:
<em>"The value of f(7) is 6.50, and it represents $6.50 remaining after playing 7 songs."</em>
