Complete the following statement.
Svetradugi [14.3K]

Answer:

if p ( x ) = x^2 + 7 x + 3 is divided by x + 4, the remainder is -9

Step-by-step explanation:

We need to find the remainder if p ( x ) = x^2 + 7 x + 3 is divided by x + 4

Dividing p ( x ) = x^2 + 7 x + 3 by x + 4

The division is shown in figure attached.

The remainder = -9

The quotient = x+3

So, if p ( x ) = x^2 + 7 x + 3 is divided by x + 4, the remainder is -9

So say we have the number: 54,321

The 5 would be worth 50,000 meaning it's in the ten thousands place.

The 4 would be worth 4,000 meaning it's in the thousands place.

.

The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

.

Hope that helps :)

Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per r
Maksim231197 [3]

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that ,

Total money he takes while going to the fair = $90

Money he spends to enter the fair = $5

Money he spends on food =$15

Total he spent now is given by

\$5+\$15=\$20

Now, he spend on rides at the fair i.e. 1.50 per ride .

Let the number of rides be x

So, cost incurred on rides = 1.5x

So, the spending money can be expressed as

20+1.50x

Now, remaining money left to him after spending on x rides too is

90-(1.50x+20)\\\\=90-1.50x-20\\\\=70-1.5x

Let f(x) denotes the function used to determine the money he has left over after rides .

So it becomes

f(x)=70-1.50x\\\\f(x)=-1.50x+70
