Answer:
y = mx+b is the equation for slope-intercept form
Step-by-step explanation:
m=slope
x=independent variable
y= y-intercept
If two lines are parallel to each other, then they have the same slope, but different y-intercepts.
So any y-intercept works basically
You could do y=2/5x+2 if you wanted or y=2/5x-7 or something like that
Hope this helped.
Answer:
1
Step-by-step explanation:
Let x represent the number. The given relation is ...
x² +(x+3)² = 17
2x² +6x +9 = 17 . . . . simplify
x² +3x -4 = 0 . . . . . . subtract 17 and divide by 2
(x +4)(x -1) = 0 . . . . . factor
The solutions make these factors zero: -4 and +1. The positive solution is 1.
The number is 1.
Answer:
![y=2sin[\frac{\pi}{4}(x+3) ]-5](https://tex.z-dn.net/?f=y%3D2sin%5B%5Cfrac%7B%5Cpi%7D%7B4%7D%28x%2B3%29%20%5D-5)
Step-by-step explanation:
The standard form for a sinusoidal function is given by:
y = Asin[B(x - C)] + D
Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation
Given:
A = 2, D = -5 (down), C = -3 (left).
8 = 2π/B; B = π/4
Therefore:
Answer:
the difference in elevation is 18.5 m
the elevation of submarine is -7.75m
so elevation of helicopter is = - 7.75 + 18.5
=10.75m
thus elevation of helicopter is 10.75 m
