The answer is B. Multiply both sides of the top equation by 2.
This is because if you multiply 3x by 2, you get 6x, and 6x is in the other equation, which makes the x-values equal
Answer:
(2,-4)
Step-by-step explanation:
When a point (x,y) is reflected across the y-axis, you need to change the sign of x. For example, if (-x,y) you need to take away the negative sign, which makes (x,y). Or, if the point is (x,y), you need to add a negative sign to the x, which makes (-x,y). So, if your point (-2, -4) is reflected across the y-axis, you need to take the negative sign off the -2, which makes (2,-4).
Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:
You should actually show congruency first
Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
Answer:
166
Step-by-step explanation:
If the four lines are tangent to the circle, know that:
NA = KA
AD = LD
LC = MC
MB = NB
The question stated that:
NA = 18 --> KA is also 18
BN = 11 --> MB is also 11
AD = 34 --> LD is also 34
BC = 31 --> MC is 20 (Because BC is BM + MC and BM is 11)
We can just add these numbers.
(18+18) + (11 + 11) + (20+20) + (34+34)
= 36 + 22 + 40 + 68
= 76 + 90
= 166
The perimeter of ABCD is 166.
