Answer:
So, y = 2x + 7;
Then, 2x = 4( 2x + 7 ) - 16;
2x = 8x + 28 - 16;
2x = 8x + 12;
- 6x = 12;
x = - 2;
Then, y = 2· (-2) + 7;
y = - 4 + 7;
y = 3.

Answer:
The triangles are congruent by SAS.
Step-by-step explanation:
The triangle have two congruent sides because it is given. The congruent angle is the angle at which they connect, these two angles are congruent because they are vertical angles.
Answer:
B.
Step-by-step explanation:
total chips = 6
chips not including yellow= 4
simplify 4/6 = 2/3
=(-4/5)^2 * -3/50
square -4/5 first; remember -4/5^2 is the same as -4/5 * -4/5
=(-4/5 * -4/5) * -3/50
multiply -4 numerators; multiply 5 denominators
=(-4 * -4)/(5 * 5) * -3/50
=16/25 * -3/50
multiply numerators 16 & -3; multiply denominators 25 & 50
=(16 * -3)/(25 * 50)
= -48/1250
simplify by 2
= -24/625 (or -0.0384)
ANSWER: -24/625 (or -0.0384)
Hope this helps! :)
