Answer:
a. (3,11) (4,15) (5,19) (6,23)
b. it's not proportional because b (from y=mx+b) is not 0
c. the equation is y = 4x - 1
d. graph the y-int (-1) on the y-intercept and then connect the points in a.
Step-by-step explanation:
C
All u have to do is add 23.5 to 23.5
Answer:


Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

For 0.4(20y+15)=x, we expand to get:


Divide through by 8

Therefore the system in slope-intercept form is:


You will have approximately $257 at the end of 8 years.
<span>zebra fish a then tetras fish (11 – a)
2.2a + 1.85(11 – a) = 22.80
2.2a + 20.35 – 1.85a = 22.80
0.35a = 2.45
a = 7 zebra and 11 – 7 = 4 neon fish
