Answer:
n = 5
Step-by-step explanation:
3n + 8 = 23
- 8 - 8 Subtract 8 from both sides
3n = 15
n = 5 Divide both sides by 3
Answer:
a. Chart (attached)
b. and c. graph attached
Step-by-step explanation:
a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.
So, when x=0, 
when x=20, 
when x=40, 
b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)
c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
Obtuse and isosceles
Isosceles means that at least two of the sides are congruent or equal.
Obtuse means that one angle of the triangle is greater than 90 degrees.
So, your answer is D and E
:)))
It is a negative graph and if you take the peak- the y intercept, it gives you the value of b. make that value negative and you should get your answer. i also put my answer in the comments if you wanted it, but you said you didn’t so..
