20x + 5y = 15
-20x -20x
5y = -20x + 15
/5 /5 /5
y = -4x + 3
Answer:
(3, 6) (3, 6) (3, 6) (3, 6)
Answer:
A
Step-by-step explanation:
If you follow the dotted lines and bring all the lines together,
angle8 = angle4 (corresponding angles)
angle8 = angle5 (vertically opposite angles)
angle5 = angle1 (corresponding angles)
Therefore, angle8 is basically the same as angles 1 and 4
Thus,
127+127=254
Given the equation <span>-4a/a+4=12/a-11, for sure we need to the solution for a.
</span><span>-4a/a+4=12/a-11
</span>-3a + 4 = 12/a - 11
-3a -12/a = -11 - 4
3a + 12 / a = 15
(3a^2 + 12) / a = 15
3a^2 + 12 = 15a
<span>3a^2 - 15a + 12 = 0
</span>
In order to get a , we need to find the roots.
(3a - 3) (a - 4) = 0
3a - 3 = 0 --> a = 1
a - 4 = 0 -- > a = 4
So the possible solutions for a are 1 and 4.
