You subtract and devide i beleve. hope iu helped sorry if wrong.
Answer:
y = -2x - 1
Step-by-step explanation:
the ? mark part or the first [] is the slope
the slope is rise / run
the "rise" is 2 down
the "run" is 1 left
so
-2 / 1 is the slope
the y intercept is -1 as the line touches the y axis at -1
so
y = -2x - 1
is your answer
Answer:
-7x/6
Step-by-step explanation:
x/2-5x/3
Taking LCM
3x/6-10x/6
(3x-10x)/6
-7x/6
Answer:
3, 5, 7, 7, 8
Step-by-step explanation:
3, 5, 7, 7, 8
the mean = (3+5+7+7+8)/5 = 30/5= 6
the mode = 7
Answer:
∡ZA = 66°
Step-by-step explanation:
Suplementary angles sum 180°
ZA + ZB = 180°
then:
(2x - 14)° + (3x-6)° = 180°
2x + 3x - 14 - 6 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40
then:
∡ZA = (2x - 14)
∡ZA = (2*40 - 14)
∡ZA = (80-14)
∡ZA = 66°
