Answer:
Both the answers will be B
If it was physics or math try to solve all problems you have and try to search for more questions to solve the more you solve the more you will gain marks ,if it was a subject that needs to memorize write down the things you forget on nots and read them in the morning .. do not forget to take a break whenever you lose your passion just believe in yourself you can do it
Answer:
x = y/2 - 1/2
Step-by-step explanation:
you can use the slope-intercept form of a line first, then change to terms of 'x'
y = mx + b where 'm' is the slope and 'b' is the y-intercept
if we use two points on the line, such as (-1, -1) (0, 1), we can find the slope
m = 1-(-1) / 0-(-1)
m = 2/1
b = 1
Slope-Intercept form: y = 2x + 1
in terms of 'x':
2x = y - 1
x = y/2 - 1/2
Answer:
Step-by-step explanation:
29.11
The discriminant of equation ax^2+bx+c = 0 is b^2-4ac.
Here b = 12, a = -4, c = -9 so discriminatn is
b^2-4ac = 12^2-4(-4)(-9) = 144 - 144 = 0.
The discrimant is 0. This tells us that there is only 1 x-intercept for this quadratic
