Answer:Yes, it is
Step-by-step explanation:
2^2+4(2)-12=0
4+8-12=0
12-12=0
0=0
Using the quadratic formula, the answers could be A B and D
Step-by-step explanation:
<u>Statement Reason </u>
∠5 and ∠7 are vertical angles Vertical angles theorem
m∠5 = m∠7 Definition of vertical angles
m∠5 = -2(3x - 4), m∠7 = 3(x - 3) - 1 Given
-2(3x - 4) = 3(x - 3) - 1 Substitution property of equality
-6x + 8 = 3x - 9 - 1 Distributive property
3x + 6x = 8 + 10 Addition property
9x = 18 Addition property
x = 18/9 Division property
x = 2 Proved
Answer:
( 1, -2)
step-by-step explanation:
- original coordinates of C: (4, -2)
if reflected over y-axis: use the formula: (x,y) → (-x,y)
- new coordinates: (-4, -2)
then if translated 5 units horizontally, there will be change in x axis:
- new coordinates: (-4+5, -2) → ( 1, -2)
