Answer:
C
Step-by-step explanation:
Answer:
Below in BOLD.
Step-by-step explanation:
1. The discriminant D = b^2 - 4ac
= 3^2 - 4*5*(-7)
= 9 + 140
= 149.
Positive value so it has 2 real solutions.
2. D = (-12)^2 - 4 * 9 * 4
= 144 - 144
= 0.
So it has one real solution.
3. D = 2^2 - 4*1*3
= -8.
It is negative so there are No real solutions.
4. D = 4^2 - 4*2*10 = 16 - 80 = -64.
No solutions.
5. D = (-12)^2 - 4*3*(12)
= 144 - 144 = 0
So its the second choice.
Answer:
4y-9
Step-by-step explanation:
y is the number, 4 times the number = 4y
so 4y-9
Answer is 283
283 x 0.35 = 99.1
Hey!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To find the perpendicular line, of any given line goes like this...
if m (slope) of this given line is 1/3, than we know that the perpendicular line has a slope of -3
Now, to find the equation of this line, we need to find out where it crosses the y-axis... And because we are not given any specific points on where the perpendicular line crosses. We see that the point it pass the y-axis is 0
So... the perpendicular line of 1/3x+2 is -3x
