1. y = -x - 2...slope here is -1. A parallel line will have the same slope
y = mx + b
slope(m) = -1
(2,-2)...x = 2 and y = -2
now we sub and find b, the y int
-2 = -1(2) + b
-2 = -2 + b
-2 + 2 = b
0 = b
so ur parallel equation is : y = -x
=========================
2. -1 = -3/2(2) + b
-1 = -3 + b
-1 + 3 = b
2 = b
parallel equation is : y = -3/2x + 2
==========================
3. parallel equation is : x = 4
==========================
4. 3 = 1/2(-2) + b
3 = -1 + b
3 + 1 = b
4 = b
parallel equation is : y = 1/2x + 4
===========================
5. y + 0 = 2(x - 5)
y = 2x - 10 <== parallel line
============================
6. neither
============================
7. if ur second equation is : 2x + y = 7, then the lines are parallel
============================
8. neither
============================
9. sometimes
============================
10. never
Where is the picture ?? I don’t understand ok
I think x should equal -2 or -3
Answer:
∠D = ∠E = 46°
Step-by-step explanation:
∠D and ∠E are interior opposite angles.
∠D = ∠E
2(x + 8) = 3x + 1
2x + 16 = 3x + 1
x = 15°
∠D = 2(15 + 8) = 2 × 23 = 46°
∠E = 3× 15+ 1 = 45 + 1 = 46°
Answer: measure angle E= 88
