-41^2

Mathematics
1 answer:
Irina-Kira [14]4 years ago
6 0

Answer:

Step-by-step explanation:

I'm going to take a leap here and say that the -41^2 should be a -41t^2 and that the expression should look like this:

-41t^2-13t+ 9

A term is a combination of variables and numbers separated by either a plus or a minus from another combination of variables and numbers. We have 3 terms: -41t^2 is one; -13t is another; 9 is the last. So this is a trinomial.

The degree of a polynomial is equal to the degree of the highest degree'd term. Since the leading term has a power of 2 and that's the highest degree of all the terms, this is a second degree polynomial, or a quadratic, to be more specific.

3 times the sum of 5 and 4 is subtracted from 30<br><br><br>Please help me I am confused ​
Zolol [24]

Answer:

- 3

Step-by-step explanation:

3 times the sum of 5 and 4 is subtracted from 30

i.e.,

3 × (5 + 4) - 30

3 × 9 - 30

27 - 30 = - 3

Thus, 3 times the sum of 5 and 4 is subtracted from 30 is equal to -3

Molly's basic cell phone plan charges $35.99 for service plus $0.21 per minute beyond the included 250 minutes in the plan. How
Ilia_Sergeevich [38]
The answer is $84.29

Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)

Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29

Solve the system of equations by substitution x+y=18, y=5x
Artyom0805 [142]

Answer:

(3, 15 )

Step-by-step explanation:

Given the 2 equations

x + y = 18 → (1)

y = 5x → (2)

Substitute y = 5x into (1)

x + 5x = 18

6x = 18 ( divide both sides by 6 )

x = 3

Substitute x = 3 into (2) for corresponding value of y

y = 5(3) = 15

Solution is (3, 15 )
