<u>Given expression:</u>

(-3x^2+4x)+(2x^2-x-11)

To simplify the expression, it is needed to open the parentheses.

\implies (-3x^2+4x)+(2x^2-x-11)

\implies -3x^2+4x+2x^2-x-11

To further simplify the expression, let us combine like terms.

\implies -3x^2+4x+2x^2-x-11

\implies x^{2} (-3 + 2)+x(4-1)-11

Now, simplify the expression as needed.

\implies x^{2} (-3 + 2)+x(4-1)-11

\implies x^{2} (-1)+x(3)-11

Finally, open the parentheses to get the simplified form

\implies x^{2} (-1)+x(3)-11

\implies \boxed{\bold{-x^{2} +3x-11}}

\text{Therefore, the simplified expression is} \ \boxed{-x^{2} +3x-11}

Answer:

SolutioN :

\bf \: \star ( - 3x^{2}  + 4x) + (2 {x}^{2}  - x - 11)

\longrightarrow \bf \:  - 3 {x}^{2}  + 4x + 2 {x}^{2}  - x - 11

\longrightarrow \bf \:  - 3 {x}^{2}  + 2 {x}^{2}  + 4x - x - 11

\longrightarrow  \boxed{\bf \:  - {x}^{2}  + 3x - 11}

Step-by-step explanation:

First

since its follow the pattern Intercept Max... Intercept Min...

Its a positive sine graph

Asin(B(x-0))<0.25

A=1

B=2π/period

period From the graph = 2π

B=2π/2π

B=1

Sin(x)<0.25

I'd go with C.

When n is a factor of a number, all factors of n are also factors of the number
Eduardwww [97]
This would be True. For example. If your number is 24, and 'n' is 12 ( a factor of 24 )
your factors of 12 (12, 6, 4, 3, 2, 1) are also included in the factors of 24 (which are 24, 12, 6, 4, 3, 2, 1)

A bus driver pays all tolls, using only nickels and dimes, by throwing one coin at a time into the mechanical toll collector.
lutik1710 [3]

Answer: a) An = An-1 + An-2

b) 55ways

Step-by-step explanation:

a) a nickel is 5 cents and a dime is 10cent so a multiple of 5 cents is the possible way to pay the tolls in both choices.

Let An represents the number of possible ways the driver can pay a toll of 5n cents, so that

An = 5n cents

Case 1: Using a nickel for payment which is 5 cents, the number of ways given as;

An-1 = 5( n-1)

Case 2: using a dime which is two 5 cents, the number of ways is given as;

An-2 = 5(n-2)

Summing up the number of ways, we have

An = An-1 + An-2

From the relation,

If n= 0, Ao= 1

n =1, A1= 1

b) 45 cents paid in multiples of 5cents will give us 9 ways(A9)

From the relation, we have that

Ao = 1

A1 = 1

An =An-1 + An-2

Ao = 1

A1 = 1

A2 = A1+Ao = 1+1= 2

A3 = A2 + A1 = 3

A4 = A3+A2=5

A5=A4+A3=8

A6=A5+A4=13

A7 =A6+A5 = 21

A8= A7+A6= 34

A9= A8+A7= 55

So there are 55ways to pay 45cents.

Step-by-step explanation:

simplify the expression into like terms

so 5a-2b-3+2b-6a (add all a and b together)

this will make

-a-3

I know how to do the equivalent sorry :(
