Answer:

-1.5m + 4n is the equivalent expression

Step-by-step explanation:

To find the equivalent expression, we combine the like terms.

We are given the following expression:

m + 4n - 2.5m

Combining the like terms:

m - 2.5m + 4n

-1.5m + 4n is the equivalent expression

I need help ASAP. I'm not good with math.
bonufazy [111]

Given:

The increase in pressure P is the linear function of the depth d.

P(d)=0.445d+14.7

The cost of dinner is $300 and $10 per students.

To find:

The initial value and rate of change and their interpretation.

Find the cost function C where n is the number of students.

Solution:

The slope intercept form of a linear function is

f(x)=mx+b          ...(i)

where, m is rate of change and b is y-intercept or initial value.

We have,

P(d)=0.445d+14.7        ...(ii)

From (i) and (ii), we get

m=0.445,b=14.7

The initial value is 14.7. It means, the pressure at sea level is 14.7 pounds psi.

Rate of change is 0.445. It means, the pressure is increasing by 0.445 pounds psi for every feet.

The cost of dinner is $300 and $10 per students.

Let C(n) be the total cost for dinner and n be the number of students.

Fixed cost = $300

Additional cost for 1 student = $10

Additional cost for n student = $10n

Now,

Total cost = Fixed cost + Additional cost

C(n)=300+10n

Therefore, the required cost function is C(n)=300+10n.

If you multiply two decimals less than 1 can you predict whether the product will be less than or greater than either of the fac
ki77a [65]

I predict that the product will be less than either of the factors.

When you multiply two numbers less than ' 1 ', you are
calculating the size of a piece of a piece.  It winds up being
smaller than either of the pieces.
