Answers

it’s a linear function so,

y = mx+b

b is 0.

m is rise/run, which is 6/3, which is 2.

so

y=2x


hope this helps!

Answer:

y = 2x

Step-by-step explanation:

the equation of proportional relationships are in the form y = mx, where m is the slope.

this means you need to solve the slope.

to find the slope, find 2 random points and do change in y divided by change in x.

for example, (3, 6) and (0, 0)

this would be (6 - 0)/(3 - 0) = 2

this means m = 2

so the equation is y = 2x

A special machine is used at a construction site to dig holes. A hole is dug to a depth of 4.75 feet when the machine hits rock. The progress slows to 3/5 feet per hour of digging. The depth of the hole must be at least 12 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the machine must continue at its present rate to complete the hole on schedule? Select from the drop-down menus to correctly complete the statement.

Answers

Answer: 12 h ; 45 m

Step-by-step explanation:

*Important: From what I can see in this image, this appears to be a test. If this is the case, please do not cheat. In any case, here is the explanation.

What we know:

Progress has been made to 4.75Rate of digging is 3/5 mphDepth must be at least 12 1/2We need to find the minimum amount of time the machine works

How to solve:

By setting up an algebraic equation, we can solve this.

Process:

Set up equation                            4.75 + 3/5x = 12 1/2Convert                                          19/4 + 3/5x = 12 1/2

                                                                95/20 + 12/20x = 250/20

Subtract                                           -95/20                 -95/20

                                                                               12/20x= 155/20

Isolate x via division                                       /(12/20) /(12/20)+Simplify                                                          

                                                                                         x= 12 11/20

Convert                                                                    12 h 33 m

Solution: 12 ; 45

The minimum amount of time taken by the machine will be 12 hours and 55 minutes.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

An exceptional machine is utilized at a building site to dig openings. An opening is dug to a profundity of 4.75 feet when the machine hits the rock. The advancement eases back to 3/5 feet each hour of digging. The profundity of the opening should be no less than 12 ¹/₂ feet before the day's over to remain on time.

Convert the mixed fraction number into a decimal number.

12 ¹/₂ feet = 12.5 feet

Let 'x' be the time. Then the equation is given as,

(3/5)x = 12.5 - 4.75

Simplify the equation, then we have

(3/5)x = 12.5 - 4.75

(3/5)x = 7.75

x = 12.9167

x = 12 + 0.9167 x 60

x = 12 hours and 55 minutes

The base measure of time taken by the machine will be 12 hours and 55 minutes.
