-7,3. if you use slide and divide
andreyandreev [35.5K]3 years ago

Answer:

(-7 , 3)

Step-by-step explanation:

3x^2 + 12x = 63 //Subtract 63 on both sides.

3x^2 + 12x - 63 = 0 //Common factor 3.

3(x^2 + 4x - 21) = 0 //Divide both sides by 3.

(x^2 + 7x - 3x - 21) = 0

x(x + 7) - 3(x + 7) = 0

(x + 7) (x - 3) = 0

x = -7 and 3

Solution: (-7, 3)

Oduvanchick [21]
<span>So we want to know what is the value of the car after three years if the car depricates in value for 48% and we know that the initial value of the car is 43900$. So if the price depricates for 48%, that means the new value is 52% of the initial value so: 43900$*0.52=22828$. So C is the correct answer.</span>

jarptica [38.1K]

Answer:

Total amount pay for dinner = Rs 1,014

Step-by-step explanation:

Given:

Amount pay for food = Rs 900

Percentage of sales tax = 1%

Percentage of trip payment = 15%

Find:

Total amount pay for dinner

Computation:

Amount pay for sales tax = Amount pay for food x Percentage of sales tax

Amount pay for sales tax = 900 x 1%

Amount pay for sales tax = 900 x 0.01

Amount pay for sales tax = Rs 9

Amount pay for trip = Amount pay for food x Percentage of trip payment

Amount pay for trip = 900 x 15%

Amount pay for trip = 900 x 0.15

Amount pay for trip = Rs 105

Total amount pay for dinner = Amount pay for food + Amount pay for sales tax + Amount pay for trip  

Total amount pay for dinner = 900 + 105 + 9

Total amount pay for dinner = Rs 1,014
