Answer:
y = -1 x = 4
Step-by-step explanation:
(X+3y=1) 5 Multiply this equation by 5 to cancel out the x
-5x+4y=-24
-5x + 4y= -24
+ 5x + 15y = 5 Add both equations together
19y = -19 Divide both sides by 19
y = -1
Plug -1 for y into one of the equations
x + 3(-1) = 1 Multiply 3(-1)
x - 3 = 1
+ 3 + 3 Add 3 to both sides
x = 4

Isolate the n. First, multiply 8 to both sides
40(8) = (-5n/8)(8)
40(8) = -5n
Multiply.
320 = -5n
Isolate the n. Note the equal sign. What you do to one side, you do to the other. Divide -5 from both sides
(320)/-5 = (-5n)/-5
n = 320/-5
n = -64
-64 is your answer for n

Answer:
The inverse of h(x) is 
Step-by-step explanation:
* Lets explain how to make the inverse of a function
- To find the inverse of a function we switch x and y and then solve
for new y
- You can make it with these steps
# write g(x) = y
# switch x and y
# solve for y
# write y as 
* Lets solve the problem
∵ 
# Step 1
∴ 
# Step 2
∴ 
# Step 3
∵
- Multiply each side by 5
∴ 5x = 2y + 6
- Subtract 6 from both sides
∴ 5x - 6 = 2y
- Divide both sides by 2
∴ 
# Step 4
∴ 
Answer:
1. predicted attendance: 141.35
2. residual: 18.65
Step-by-step explanation:
1. Predicted attendance is ...
y = -5.9·5 +170.85 = 141.35
__
2. As the problem statement tells you, ...
actual value - predicted value = residual
160 - 141.35 = 18.65 . . . the residual
