Answer:
C. 0
Step-by-step explanation:
–4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac if >0 we have 2 real solutions
=0 we have 1 real solutions
<0 we have 2 imaginary solutions
a = -4, b =3 c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions
Step-by-step explanation:
Slope of line ST = Slope of line PQ = -3.
y = -3x + c
When x = 3, y = -1
=> (-1) = -3(3) + c, c = 8
Therefore the equation of line ST is y = -3x + 8 and the y-intercept is 8.
Answer:
D (2, 1)
Step-by-step explanation:
Fir an in-detailed representation, image below
- Started with plotting the given center (yellow)
- From the center: go 5 units up, down, right and left (light blue)
- You will have 5 points plotted now
- connect the light blue dots to form a circle (red, not to scale!)
- Now, locate every choice point, which one is on the red line?
- D!!!!!

The angles of a triangle always equal 180.
You do 180 - 80 - 45. X = 45.
