Answer:

y = 3x - 2

Step-by-step explanation:

Use the point-slope equation since we are given a point that the line passes through and its slope:

y - y1 = m(x - x1)

(-2, -8), m = 3

Substitute these values into the equation.

y - (-8) = 3(x - (-2))
y + 8 = 3(x + 2)
y + 8 = 3x + 6
y = 3x - 2

The equation of the line that passes through the point (-2, -8) and has a slope of 3 is y = 3x - 2.

Answer:

x - 231 ≤ 459

Step-by-step explanation:

Given:

Elevation ranges below sea level = 228 ft

Elevation ranges above sea level = 690 ft

Elevation = x

Computation:

Ideal range = [690-228] / 2 = 231

Tolerance range = [690+228] / 2 = 459

So,

x - 231 ≤ 459

Help me plz The formula K=59(F−32)+273.15 converts temperatures from Fahrenheit F to Kelvin K.

quester [9]

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

$k = 59(f - 32) + 273.15$

Subtract the sides of the equation minus -273.15

$k - 273.15 = 59(f - 32)$

Divided the sides of the equation by 59

$\frac{k - 273.15}{59} = \frac{59}{59} (f - 32) \\$

$\frac{k - 273.15}{59} = f - 32 \\$

Subtract the sides of the equation plus 32

$\frac{k - 273.15}{59} + 32 = f \\$

And we're done.

Thanks for watching buddy good luck.
