4. The equation is an exponential function where all y coordinates are above 4 (range is y>4), so for y=4 (answer D) there are no solutions. y=4 is the asymptote.

5. In a formula ax^2 + bx + c the discriminant is b^2-4ac. In this example the discriminant is 9-4*3*6 = -63. The fact that this value is negative reveals that this equation has no (real) solutions, only imaginary.

6. y=2x^2-x-5. Trial and error.

What is the equation of a line that has a slope of 2, and contains the point (4,6)?
Tems11 [23]

Answer:

y= 2x -2

Step-by-step explanation:

You would use point- slope formula. y-y = m(x-x). With your numbers it would end up looking like this ---->  y-6 = 2(x-4), then do the distributive property which then gives you ----> y-6 = 2x - 8, then subtract 6 on both sides and you get --->  y = 2x - 2. Hope this helped!!!!

William travels only on Saturdays and Sundays and has flown 1,020 miles this month. Jason travels every weekday and has flown 2,
Fantom [35]

Answer:

William

Step-by-step explanation:

There are 8 Saturday and Sunday in a month. William travels only on Saturdays and Sundays and has flown 1,020 miles this month. <em>He has travelled (1020/8) miles per day = 127.5 miles/day</em>

There are 30-8 = 22 weekdays in a month. Jason travels every weekday and has flown 2,200 miles this month. <em>It would mean that he travelled (2200/22) = 100 miles/day.</em>

It is very clear that no of miles travelled per day by William is more than the no of miles travelled per day by Jason for this month.
