Answer:9
Step-by-step explanation:
4x4=16
16-7=9
Answer:
B
Step-by-step explanation:
B
x - 4 squared provides 2 real zeros that are the same. These two are not distinct.
The other two come from x^2 - 7x + 10 which has a discriminate of
sqrt(7^2 - 4*1*10) = sqrt(9) = +/- 3 leading to something real and different.
Answer:
54, when i saw it i had some trouble but now i understand it. Hope this helps!
First find the slope of the line segment joining the points.
Slope = ((-5)-7)/(1-(-3)) = -3
The slope of any perpendicular to the line is 1/3
Find the midpoint of the line segment by taking the average of the coordinates.
x-coord of midpoint = (-3+1)/2 = -1
y-coord of midpoint = (7-5)/2 = 1
Midpoint : (-1,1)
Point-slope equation for line of slope 1/3 that passes through (-1,1):
y-1 = (1/3)(x+1)
Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
