A:
p = 8n - 30
170.00 = 8n - 30 add 30 to each side
200.00 = 8n divide by 8
25 = n 25 items were bought.
B:
The profite would decrese
8(25) - 40
200 - 40
160 original was 170 but it decreased by 10$
hope this helped :)
There is a thing that you can do on there to find the answers all u do is crtl u then scroll all the way down
Answer:
65
All the other numbers if you add up their digits it is 8.
1 + 7 = 8
2 + 6 = 8
4 + 4 = 8
6 + 5 = 11
26
Is only number divisible by 13.
44 is only divisible by 11
Step-by-step explanation:
Answer: a real number
Step-by-step explanation:
you technically can't have negative of anything in real life so that makes -5 not a real number.
Answer:
y = -
x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
= - ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = -
x + 3 ← equation of line
