Answer:

-19,-13,-7,-1

Step-by-step explanation:

First term (1):

f(1) = 6(1) - 25 = 6 - 25 = -19

Second term (2):

f(2) = 6(2) - 25 = 12 - 25 = -13

Third term (3):

f(3) = 6(3) - 25 = 18 - 25 = -7

Fourth term (4):

f(4) = 6(4) - 25 = 24 - 25 = -1

The first four terms are: -19,-13,-7,-1

3. Ahmed wants to buy a new carpet for his house. The cost of the carpet is $240. One day the carpet shop has a special offer of
Mamont248 [21]

Answer:

After using the offer the carpet would cost Ahmed $180.

Step-by-step explanation:

Given:

Cost of the carpet = $240

Discount percent = 25%

We need to find the cost of the carpet after discount.

Solution:

First we will find the Discount cost.

Now we know that;

Discount cost is equal to Discount percent multiplied by Cost of the carpet divided by 100.

framing in equation form we get;

Discount cost = \frac{25}{100}\times 240 = \$60

Now we will find the Cost of the carpet after discount.

Now we know that;

Cost of the carpet after discount is equal to Cost of the carpet minus Discount cost.

framing in equation form we get;

Cost of the carpet after discount = \$240-\$60= \$180

Hence After using the offer the carpet would cost Ahmed $180.

Solve the equation for x, where x is a real number (5 points): <br> 2x^2 + 7x - 9 = -3
Tanya [424]
Add 3 to both sides so that the equation becomes 2x^2 + 7x - 6 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                              x = [ -b ± √(b^2 - 4ac) ] / (2a)
                              x = [ -7 ± √(7^2 - 4(2)(-6)) ] / ( 2(2) )
                              x = [ -7 ± √(49 - (-48) ) ] / ( 4 )
                              x = [ -7 ± √(97) ] / ( 4)
                              x = [ -7 ± sqrt(97) ] / ( 4 )
                              x = -7/4 ± sqrt(97)/4
The answers are -7/4 + sqrt(97)/4 and -7/4 - sqrt(97)/4.
