1) we find out the equation of the line
point-slope form; we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀)
In this case:
point: (4,5)
slope: 6
Therefore:
y-5=6(x-4)
y-5=6x-24
y=6x-24+5
y=6x-19 (slope-intercepted form)
2)we find out "y" when x=24
if x=24; then
y=6(24)-19=144-19=125
Answer: y=125
Answer:
y = .025x +20
The y intercept is the value when x = o, or the starting value. In this case, it is the temperature in degrees F at a depth of 0 meters.
Step-by-step explanation:
We have a point a (0,20) and a point at (2 , 20.05)
We can find the slope from
m = (y2-y1)/(x2-x1)
= (20.05-20)/(2-0)
= .05/2
=.025
One of the points (0,20) is the y intercept since x=0
We can use the slope intercept form of the equation
y= mx+b
y = .025x +20
The y intercept is the value when x = o, or the starting value. In this case, it is the temperature in degrees F at a depth of 0 meters.
Answer:
Step-by-step explanation:
y+2x-3+4x^2+3x-5y
Combine terms
4x^2-4y+5x-3
g(7-h) +3
Now g = 5 and h=2, So lets plug the values
5(7-2) +3
= 5(5) +3
= 25 + 3
= 28
Answer:
Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:
write f(x) as y (since that's what it represents)
Swap x and y
Square both sides
Add 1 to both sides
So this gives you the equation:
