Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
The fish, the fishing pole and the water surface are all in equivalent ratio, and the fish is 21 feet from the hook
<h3>How to determine the distance between the fish and the hook?</h3>
To do this, we make use of the following equivalent ratio
3 : 12.6 = 5 : x
Where x represents the distance between the fish and the hook
Express the ratio as a fraction
12.6/3 = x/5
Multiply both sides by 5
x = 5 * 12.6/3
Evaluate
x = 21
Hence, the fish is 21 feet from the hook

Answer:
Step-by-step explanation:
the 2nd line can be rewritten as y < x-3
So, any value that is less than both 4x+4 and x-3 will work
Pick any value you want for x, and figure y possibilities
x=0; x-3=-3, 4x+4=4, so y<-3 ... (0,-5) will work

It's easier if you know 1 minutes = ... miles
If, 80 minutes = 8 miles
Then, 1 minute = 0.1 mile
Therefore 210 minutes = 210 . 0.1 miles = 21 miles

Step-by-step explanation:
A recipe for sparkling grape juice calls for 1.5 quarts of sparkling water and 3/4 quart of grape juice.
The ratio of sparkling water to grape juice is
So, to make 100 quarts of punch you need x quarts of grape juice and 2x quarts of sparkling water.
Hence,
