and y-intercepts is -1
Step-by-step
Answer:
Step-by-step explanation:
x² - 7x - 18 = 0
Product = -18
Sum = -7
Factors = 2 , (-9) {2*(-9) = -18 & 2 +(-9) = -7}
x² + 2x - 9x - 18 = 0
x(x + 2) - 9(x + 2) = 0
(x +2)(x - 9)= 0
x + 2 = 0 ; x - 9 = 0
x = -2 ; x = 9
x = -2 , 9
Sale price = 272000
Reduction percentage = 15%
Let the original price = x
Reduction = 15% of x
Original price - reduction price = Sale price
x - 15% of x = £272000
x = 3200 * 100
Original price = £320000
Answer:
(i) 7/10
(ii) 3/10
(iii) 1/5
(iv) Rs 40,000
Step-by-step explanation:
The fraction of the salary spent on food = 1/2
The fraction of the salary spent on rented house fee = 1/5
(i) The fraction spent for both food and rental fee = (1/2) + (1/5) = (5 + 2)/10 = 7/10
(ii) The remainder (rest) of the salary = 1 - 7/10 = 3/10
The fraction of the remainder spent for children's education = 1/3
The fraction of the total salary spent for the children's education = (1/3) × (3/10) = 1/10
(iii) The remaining portion deposited in the bank = 1 - (1/10 + 7/10)) = 2/10 = 1/5
(iv) The amount equal to portion of 1/5 of his salary deposited in the bank is Rs 8000
Let <em>x</em> represent his whole salary, we have;
(1/5) × x = Rs 8,000
x = 5 × Rs 8,000 = Rs 40,000
His whole salary is Rs 40,000.
