Answer:
y = 3x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 9 ← is in slope- intercept form
with slope m = 3
• Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (2, - 2) into the partial equation
- 2 = 6 + c ⇒ c = - 2 - 6 = - 8
y = 3x - 8 ← equation of parallel line
Answer:
y = 1/20 x + 5
Step-by-step explanation:
Let the height of the sand dune after x years be represented by the equation
y = mx+c where;
m is the rate at which the hills is eroding
c is the height of the dunes above the sea
If The hill is eroding at a rate of 1 foot per 20 years,then the rate of eroding per year will be;
1foot = 20years
m = 1year
Cross multiply
20m = 1
m = 1/20 foot/yr...
c = 5foot
Substitute into the formula:
y = 1/20 x + 5
Hence the equation that represent the situation is y = 1/20 x + 5

Step-by-step explanation:
Detailed explanation and calculation is shown in the image below.
Answer:
Step-by-step explanation:
The square root property requires a quantity squared by itself on one side of the equation. The only quantity squared is x, so divide both sides by 2 before applying the square root property.
The x variable should be isolated on one side of the equation. The x variable is squared so before performing the square root property where we take the square root of both sides, we divide both sides by 2, then take the square root of both sides.
Dividing both sides by 2.
Taking the square root of both sides.
3-5y= 2x
-5y= 2x-3
y= (-2/5)x + 3/5
y + 2 = (-2/5)(x + 3)
y + 2 = (-2/5)x - (6/5)
y + 10/5 = (-2/5)x - 6/5
y = (-2/5)x - 16/5 is the answer
