Answer:
The answer to your question is Ф = 45°
Step-by-step explanation:
Data
A (1, 4)
B (-1, 2)
Process
1.- Find the slope of the line
formula
m =
Substitution
m =
Slope definition, is the steepness of a line and also is the tangent of the angle of the line.
tangent Ф = slope
tangent Ф = 1
Ф = tangent⁻¹ 1
Ф = 45°
Step-by-step explanation:
° put the value of x at the place of x to get y , put value of y to get x.
° x = -4
y = -2x + 3
y = -2(-4) + 3
y = 8 + 3 = 11
° x = -1
y = -2(-1)+3
y = 2 + 3
y = 5
• y = 3
y = -2x + 3
3 = -2x + 3
0 = -2x
x = 0
• y = -3
-3 = -2x + 3
-6 = -2x
x = 3

Kindly check explanation
Step-by-step explanation:
Given the sound model:
s = 10│x - 4│+ 50
x = measure of music played ; s = sound level I. Decibel
Number measure at which sound level = 80
Plugging values into the equation:
80 = 10│x - 4│+ 50
Subtract 50 from Both sides so as to eliminate the 50 on the right hand side
80 - 50= 10│x - 4│+ 50 -50
30 = 10 |x - 4| + 0
Divide through by 10 so as to isolate the absolute inequality expression
3 = |x - 4|
Eliminate the absolute value sign
±3 = x - 4
Hence,
x = - 3 + 4 = 1
x = 3 + 4 = 7
Hence, x = 1 ; x = 7
