A drill is used to dig down into the earth. After 2 hours, the drill is 12 meters below the surface. After 5 hours, the drill is 30 meters below the surface. Which equation represents the depth of the drill in meters, y, after ​x hours of drilling?A line passes through the origin and (4, 5). Which point is also on the line?

Answers

Answer 1
Answer:
6y = x
Step-by-step explanation:
All that equation is saying is that for every 1 hour drilled (x), 6 meters (y) are drilled.
y = distance in meters
x = time
12y = 2x
12y/2 = 2x/2
6y = x
30y = 5x
30y/5 = 5x/5
6y = x

Lmk if I’m wrong

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal.

Answers

Answer:

x = 50

Step-by-step explanation:

the angle next to x is 65 so the angle on the oposite side will also be 65.

a straight line = 180

so 180 - 65 -65 = 50

x = 50

James used substitution to solve this system of equations. Which could be the result of his first step
2x+3y=12
y=x+1.5
A..y=2x+3y+1.5
B.2x+3(x+1.5)=12
C.2x+3x+1.5=12
D.y=2x+3y

Answers

the answer would be B. :)
B, it's B because the system gives you what Y equals and so you need to substitute (x+1.5) for the y in your equation. From there solve to get- 2x+3x+4.5=12. From here you will want to add like terms, 2x+3x= 5x. Your new equation should look like this- 5x+4.5=12. From here solve for x.

30x+ 600 ≥ 1,500

Answers

Answer:

x ≥ 30

Step-by-step explanation:

30*30 = 900 and when we add 600 to that, we get 1,500 which is the lowest possible number for the left side of the equation to equal. If x equals anything above 30, then it will automatically equal a number greater than 1,500 when added to 600.

(sorry this is confusing, I'm not very good at explaining things. I hope it helped anyway)

Answer:

x > 30

Step-by-step explanation:

replace > with=

30x +600=1500

take 600 to the other side

30x=1500-600

30x=900

x=30

therefore x > 30
