To factor by a binomial, I like to use synthetic division (You can use long division but it is more work).


We are actually given a binomial because if -2 is a zero, the binomial is represented by (x- (-2)) or (x+2)

To use synthetic division,

-2 | 1  2  -9  -18
         -2   0   18
____________
      1  0  -9    0

Therefore, you know the constants of the equation which is equal to

1x^2 +0x -9x +0

x^2-9x

The full equation is equal to (x+2)(x^2-9x)

Write the slope- intercept form of the equation of the line passing through the point (3,5) and parallel to the line y=3x+6.
seropon [69]

Answer: The gradient of the line passing through is 3, thus the equation of the line becomes y=3x-4.

Step-by-step explanation: The parallel lines gradients that have similar gradients, so now we have the gradient of 3 because its similar to the other gradient. To get the equation of the line we use this equation: y=mx+c, we have to substitute the x and y to get the constant c.

5=3(3)+c

c= -4

y=3x+c

5. A new car is offered for lease for $291 per month for
Elodia [21]

Answer: B

$10,390.75

Step-by-step explanation:

Given that the lease = $291 per month

Lease pay = 291 × 24 = $6984

Time = 24 months

down payment = $458.

The lease allows for 12,000 miles per year and includes a $0.35 per mile charge for miles driven in excess of that amount. 

For the car to be driven a total of 32,425 miles. 

Excess = 32425 - 24000 = 8425 miles

Charges = 0.35 × 8425 = $2948.75

The cost for two years for this vehicle will be

2948.75 + 458 + 6984 = $10390.75

Some examples of additions with integers with 5 terms or more are:

  • 20 + 1 + 1 + 2 + 1= 25
  • 2 + 1 + 1 + 2 + 1= 7
  • 20 + 2 + 1 + 2 + 1= 26
  • 20 + 1 + 1 + 3 + 1= 26
  • 20 + 1 + 1 + 4 + 1= 27
  • 200 + 1 + 1 + 2 + 1= 205

<h3>What is an Integer?</h3>

In mathematics, an integer is a whole number that is used to represent a value and is not a fraction.

Furthermore, we can make the addition of integers as they would increment based on the number they are being incremented with and this has been shown above.
