A) x=1,-13
B) x= -1 +- square root of 21 dvided by 10
C) x= 3 +- i square root of 7 divided by 2
D) x= 1 +- i square root of 11 divided by 4
From the point-slope formula, we have:
where m is the slope, (x_0,y_0) are known points.
In this case, we have the slope and two points, we can substitute in the formula to get:
therefore, a=3
Note: you can also find a if you use the slope formula.
<1 = <2
vertical angles (congruent)
<3 = <2
corresponding angles (congruent)
so that: <1 = <2 = <3 = 112 degree
Answer:
72
Step-by-step explanation:
8 times 9 equals 72
4 + 3/5 = 23/5 and
2 + 1/3 = 7/3 get a common denominator = 15 ....so....
23/5 = 69/15 and
7/3 = 35/15
So
69/15 - 35/15 =
34/15
