Evaluate: -1/4 + 17 + (4/5)+ 1/4 + 13 + (-4/5)

Answer:

-1 i believe because that is the only x intercept. i apologize if this is wrong

Step-by-step explanation:

Answer:

So first you have to do 12-2 since it's in parenthesis. It is 10. 5+4 is 9, and 9 times 10 is 90. 3 squared is 9, then you divide 90 by 9. The answer is 10.

I have no idea??? I'm 3rd grade.

Answer:

7 / 1

Step-by-step explanation:

0.¯7 = 0.7777.....

10x = 7.7777.....

9x = 0.7777.....

(-) (-)

___________

1x = 7

x = 7 / 1

Simplified fraction = 7 / 1.

Answer:

Your Answer Would be the 3rd Option.

Step-by-step explanation:

The Initial Value is : 4. All you have to do is look for when the x = 0

ROC: 1/2. Minutes =x, Inches= Y. To find ROC, take

Y2 - Y1

----------

X2 - Y1

Replacing those with numbers:

5 - 4

-------

2 - 0

Your ROC is 1/2 .

Equation:

y= 1/2x + 4

Know that The 4 is the initial value, so it's always in that spot. Your ROC is always Next to the x, which also means it's the slope.

Answer: C. It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.

Step-by-step explanation:

The option that is true concerning hull fouling from commercial shipping and recreational boating is; C: It is difficult to prevent since ship hulls begin, conduct, and end voyages in water.

Hull fouling is a phenomenon that arises due to the accumulation of marine growth that leads to reduction in speed of the vessel, increase in the bunker consumption and also the accumulation of more cleaning costs.

Now, this marine growth such as water hyacinths and others are very hard to prevent because the ship lull is not something that can be brought to land before movement as it starts and ends it's journey inside the water.

Thus, the correct option is C.

The line that has a constant of proportionality of 5 between y and x is: line A.

The constant of proportionality of a proportional relationship is found using the formula:

Constant of proportionality, k = y/x, where (x, y) is any point on the proportional graph.

Find the constant of proportionality for line A using a point, (1, 5):

Constant of proportionality, k = y/x = 5/1 = 5

Find the constant of proportionality for line B using a point, (3, 5):

Constant of proportionality, k = y/x = 5/3

Find the constant of proportionality for line C using a point, (3, 2):

Constant of proportionality, k = y/x = 2/3

Therefore, the line that has a constant of proportionality of 5 between y and x is: line A.

We can write the information we know as ordered pairs.  The independent variable, or x, in this case would be the amount of time, and the dependent variable, or y, would be the amount of money.  This is because the amount of money charged changes depending on the amount of time.  This gives us the ordered pairs (3, 26) and (5, 42).  Using the formula for slope we have:

.  A slope of 8 tells us that the hourly rental is $8.  We can use this to back up and see what the rental fee is.  When renting the kayak for 3 hours, Jake paid 26.  We know that it costs $8 per hour; 8(3) = 24.  This leaves us 26-24=$2 for the rental fee.  The equation would then be

y = 8x + 2.

Writing this as a function would be f(x) = 8x + 2.

To graph this, we would label the x-axis as time (hours) and the y-axis as money (dollars).  We would go up to the y-intercept, 2, and plot our point.  (The y-intercept is 2 because in the form y=mx+b, b is the y-intercept; that's where our 2 is.)  From here, we know the slope is 8=8/1, so we would go up 8 and over 1 to the right to plot our next point.  Then we would draw our line between these two points.

The value of y when x= 4

Step two:

substitute the value of x in the expression to get y

After 4 years the depth will increase by 42.8 in

Answer:

No solution

Infinitely many solutions

One solution

Step-by-step explanation:

The first expression:

           -2(3x  - 1) = -6x -1

  Expand the parentheses;

           -6x + 2  = -6x -1

             -6x + (-6x) = -1 -2

                 0 = -3

This problem has no solutions

Second expression:

          2(3x-1) = 6x -2

  Expand the parentheses;

          6x - 2  = 6x -2

           6x -6x = -2 + 2

             0 = 0

This problem has infinitely many solutions

Third expression:

2(3x - 1) = -6x -2

    Expand the parentheses;

       6x -2 = -6x - 2

        6x + 6x = -2 + 2

           12x = 0

               x  = 0

This equation has only one solution
