8^2=8x8=16 then you add 4 and subtract 12 which will get you 56. correct me if i’m wrong.
Answer:
C. x = 3, y = 2
Step-by-step explanation:
If both triangles are congruent by the HL Theorem, then their hypotenuse and a corresponding leg would be equal to each other.
Thus:
x + 3 = 3y (eqn. 1) => equal hypotenuse
Also,
x = y + 1 (eqn. 2) => equal legs
✔️Substitute x = y + 1 into eqn. 1 to find y.
x + 3 = 3y (eqn. 1)
(y + 1) + 3 = 3y
y + 1 + 3 = 3y
y + 4 = 3y
y + 4 - y = 3y - y
4 = 2y
Divide both sides by 2
4/2 = 2y/2
2 = y
y = 2
✔️ Substitute y = 2 into eqn. 2 to find x.
x = y + 1 (eqn. 2)
x = 2 + 1
x = 3
Answer:
Only A and C are functions.
Step-by-step explanation:
X-values cannot repeat in the case of functions.
The exterior angle is supplementary to the adjacent angle (they form a linear pair) and is the sum of the two angles in the triangle that are not adjacent to it. For example, in number 2, the exterior angle is 28+40=68 degrees. You can use the other method to check. 68 degrees is supposed to be in a linear pair with 112 degrees, which it is. So the answer to number 2 would be 68 degrees.

Answer: 250 cameras; $10,000 spent; 15,000 made
Step-by-step explanation:
1) FInd the profit. 60-40=20. This means that they make a profit of $20 per camera.
2) How many cameras to break even? 5000/20=250. The answer is 250 cameras!
3) How much money has been spent? 40x250= $10000 spent.
4) How much money has been made? 60x250= $15000 made.
