Complete question :

A lake near the Arctic Circle is covered by a 3 meter thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After four weeks, she is only 1.6 m thick. Let S(t) denote the ice sheet's thickness S (measured in meters) as a function of time t (measured in weeks). Write the function's formula

Answer:

S(t) = 3 - 0.3t

Step-by-step explanation:

Given that:

Initial thickness = 3m

Assume the rate of decrease is constant

Thickness after 4 weeks = 1.6 m

To obtain a function for the scenario described above :

We can observe that the function is a linear function, given that rate of decrease per week is constant :

To obtain the rate of decrease :

Change after 4 weeks :

(Initial thickness - thickness after 4 weeks) / number of weeks

(3m - 1.6m) / 4

= 1.2m / 4

= 0.3 m per week

General form of a linear function :

y = mx + c

m = rate of change per unit

Hence, our function becomes ;

S(t) = 3 - 0.3t

Answer:

f(x) = 1/3x + 1

Step-by-step explanation:

slope-intercept form is

f(x) = mx + b

so just put the points in and you have:

f(x) = 1/3x + 1

also b stands for the y-intercept so if you look at your point (9,1) than your y-intercept would be 1.

The point (5, 13) is a solution to the system

The system of equations is given as:

[tex]y = 4x - 7[/tex]

[tex]2x + y = 23[/tex]

The solution is given as: (5,13)

To determine if the coordinate point is a solution of the system of equations, we have to substitute the x and y values in the equations.

So, we have:

[tex]y = 4x - 7[/tex]

[tex]13 = 4 \times 5 - 7[/tex]

[tex]13 = 13[/tex]

[tex]2x + y = 23[/tex]

[tex]2 \times 5 + 13 = 23[/tex]

[tex]10+ 13 = 23[/tex]

[tex]23 = 23[/tex]

The above equations are true.

Hence, the point (5, 13) is a solution to the system

Answer:

-8

Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.

how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Step-by-step explanation:took it on edge!

Answer:

y = 1/2x + 1

Step-by-step explanation:

slope-intercept form: y = mx + b

If you have a slope of 1/2, m = 1/2

y = 1/2x + b

To find b, plug in the known point.

4 = 1/2(6) + b

Solve.

4 = 3 + b

b = 1

Plug b into your equation.

y = 1/2x + 1

Answer:

X = 6

Step-by-step explanation:

17 - 5 = 12

12/2 = 6

hope this helps...

Answer:

6

Step-by-step explanation:

Find x

Try to get x by itself

2x + 5 = 17

subtract 5 on both sides

2×+5(-5)=17(-5)

by subtracting 5 from its opposite, it turns to 0

now we are left with

2x=12

Next we need to divide

2x is like 2(x) which is multiplication

the inverse is division

when we divide, whatever u do to one side u do to the other

2x/2=12/2

×=12/2

we finally got x by itself

we can break 12/2 even further by dividing and you'd get

×= 6
