Answer:
x=-2/5
Step-by-step explanation:
the answer is the last one
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.
Dividing both sides by x for the given values, k becomes 18/4 = 4.5
If that’s meant to be x^2 - 6x - 16
Then factorise to (x+2)(x-8)
So x intercepts are -2 and 8
Answer:
the answer is the first one
Step-by-step explanation:
39.99 rounded up is 40.00
19.99 rounded up is 20.00
40.00*0.05 = 2, 40-2 = 38
20.00*0.15 = 3, 20-3 = 17*.05 = 0.85, 17-0.85 = 16.15
38+16.15 = 54.15
