D : y = ax + b
a = (-8 + 7) / (-9+ 1) = 1/8
D : y = (1/8)*x + b
-7= (1/8)*(-1 ) + b
b = (1/8)*(-1 ) + 7 = -55/8
D : y = (1/8)*x - (55/8)
Answer:
d=7/2
Step-by-step explanation:
3/4d-1/2=3/8+1/2d
multiply all by 8, to make them into whole numbers (makes it easier)
6d-4=3+4d
move terms
6-d-4d=2d
3+4=7
7=2d
d=7/2
Answer:
∠AXC = 46°
∠BXC = 23°
Step-by-step explanation:
If XB is the angle bisector of ∠AXC then XB bisects ∠AXC t at X. Hence;
∠AXC = ∠AXB+∠BXC and ∠AXB= ∠BXC
The equation becomes
∠AXC = ∠AXB+∠AXB
∠AXC = 2∠AXB
Given
m∠AXB=23°
Substitute the given angle into the expression above to get ∠AXC since we are not told what to find but we can as well find ∠AXC
∠AXC =2(23)
∠AXC = 46°
<em>Also note that since ∠AXB= ∠BXC,</em> <em>then ∠BXC will be 23°</em>
For number 2 the correct answer is 3, number 3 the correct answer is 1/8, for number 7 the correct answer is 8/63, for number 4 the correct answer is 2/15, and the correct answer for number 8 is 25/78.
