Combine the like terms to create an equivalent expression: 5n+6+(-7n)

Answer:

-2n + 6

Step-by-step explanation:

To combine this expression, we simply put the like terms, the coefficient with the same variables, and constants together.

5n + 6 + (-7n)

So we can reorganize this:

(5n + -7n) + 6

==> (-2n) + 6

==> -2n + 6

So that is the equivalent expression with the combination of like terms.

Cheers.

Answer:

-2n +6

Step-by-step explanation:

The expression we are given is:

5n + 6 + (-7n)

We want to combine like terms. First, let's analyze each term.

5n ⇒ has a variable, "n"

5 ⇒ does not have a variable

-7n ⇒ also has a variable, "n"

The like terms in this case are 5n and -7n, since they both include a variable. Let's combine the like terms.

5n + 6 + (-7n)

(5n - 7n) +6

Subtract 7n from 5n.

(5-7) *n +6

(-2)*n +6

(-2n)+6

-2n + 6

There are no more like terms, so this is simplified as much as possible.

The expression 5n+6+(-7n) after combining the like terms is -2n+6.

The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?​Shown working out pl
8_murik_8 [283]

Let numbers be x and y

ATQ

  • x+y=49---(1)

  • x-y=9---(2)

Adding both

\\ \sf\longmapsto 2x=58

\\ \sf\longmapsto x=\dfrac{58}{2}

\\ \sf\longmapsto x=29

Now putting value in eq(2)

\\ \sf\longmapsto x-y=9

\\ \sf\longmapsto 29-9=y

\\ \sf\longmapsto y=20

Question 2*
lilavasa [31]

Answer:

The average rate of change between these times is 68 miles per hour

Step-by-step explanation:

Here, we are to determine the average rate of change between hour 2 and hour 7

The distance traveled at hour 2 is 140 miles

The distance traveled at hour 7 is 480 miles

So we can say we have two points and we want to know the rate of change between these points

Mathematically, we can represent the rate of change as Δ

Thus, between the two different times, we have;

Δ = (D7-D2)/(T7-T2)

where (T7,D7) = (7,480) and (T2,D2) = (2,140) represents the time and distance at hour 2 and hour 7 respectively

Now inputing the values into the equation, we have;

Δ = (480-140)/(7-2) = 340/5 = 68 miles/hour

In the xy-plane, the graph of function f(x) has zeros at −5, −2, and 2. Write the polynomial function.
Alona [7]

Answer:

f(x) = x^3 +5x^2-4x-20

Step-by-step explanation:

Given

Zeros: -5,-2,2

Required

The polynomial function

If a function has a, b and c as its zeros, the function is:

f(x) = (x - a)(x - b)(x - c)

So, we have:

Zeros: -5,-2,2

f(x) = (x - (-5))(x - (-2))(x - 2)

Open the inner brackets

f(x) = (x +5)(x +2)(x - 2)

Expand the difference of two squares

f(x) = (x +5)(x^2 - 4)

Expand

f(x) = x^3 +5x^2-4x-20
