Answer:
£120
Step-by-step explanation:
If the phone has been discounted by 35%, then it is now 65% of the original price (as 100 - 35 = 65).
Divide the discounted price by 65 to find the amount per 1%, then multiply by 100 to get the original price.
(78 ÷ 65) x 100 = £120
Answer:
k = 11
Step-by-step explanation:
What the factor theorem is telling us is that if x + 1 is a factor of 2x - kx²-8x + 5 then when x = - 1 is put into the equation, the result will be 0. That's because x +1 = 0 when x = - 1
f(-1) = 2(-1) - k(-1)^2 - 8(-1) + 5
f(-1) = -2 - k(1) + 8 + 5 = 0
-k*(1) + 11 = 0
-k = -11
k = 11
