Answer:
Description
Step-by-step explanation:
a. 2 solutions
b. 2 imaginary solutions
c. If the discriminant is positive, then it will have 2 real solutions as the square root of a positive number always equals a positive number. If the discriminant is negative, the quadratic equation will have 2 imaginary solutions, as the square root of a negative number is always imaginary. If the discriminant equals 0, it will have only 1 real solution.
If they drove a total of 5,300 miles in 2 days, and on the second day they drove 10 more miles then the 1st day.
5,300 ÷ 2 = 2,650
they drove 10 miles less on the first day
2,650 - 10 = 2,640
They drove 2,640 miles on the first day.
Hope this helps. :)
Answer:
a. y = 3.
b. y = -2.
Step-by-step explanation:
a. Parallel to y = 0 means parallel to the x- axis ( y = 0 is the x axis). The equation will be of the form y = something.
As it passes through the point (-3,3) it must therefore be y = 3.
b. Perpendicular to x = 0 means perpendicular to the y axis so the equation will be y = -2 (because it passes through (5, -2).
