Answer:
B. 1
Step-by-step explanation:
The slope is calculated by taking the difference in the y-coordinates of two points and dividing that by the difference in the x-coordinates of those two points.
Here, we have (6, -12) and (15, -3).
The difference in the y-coordinates is:
15 - 6 = 9
The difference in the x-coordinates is:
-3 - (-12) = -3 + 12 = 9
Divide 9 by 9:
9/9 = 1
The slope is thus 1, and the answer is B.
Standard form is when the polynomial is from the largest exponet to the smallest exponet. The answer is D
Answer:
x = 67°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x , that is
x = 180° - (38 + 75)° = 180° - 113° = 67°
Step-by-step explanation:
First term (a) = 21
common difference (d) = 14-21= -7
general equation for nth term = a+(n-1)d
The 38th term of the AP= 21+(38-1)(-7)
= 21+(37)(-7)
= 21 −259= −238
