Answer:
Can you be more specific of what you are looking for please? i just entered it into the calc but what are you looking for as the answer?
Answer:
f(x) = (x - 4)² - 13
Step-by-step explanation:
Given
f(x) = x² - 8x + 3
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
f(x) = x² + 2(- 4)x + 16 - 16 + 3 = (x - 4)² - 13
Yes, they are.
You're not changing anything fundamental about them. They're just flipped expressions.
Answer:
Option B. 1 : 3
Step-by-step explanation:
There are two triangles shown in the picture attached ΔABC and ΔCD.
In these triangles sides AB and DE are parallel and BC is transverse line so ∠ABC = ∠EDC (corresponding angles)
Similarly AC is transverse to parallel lines AB and DE, so ∠BAC = ∠DEC (corresponding angles)
∠ACB is common in both the triangles.
Therefore ΔABC and ΔDEC are similar.
We know in similar triangles corresponding sides are in the same ratio.


Therefore ratio of y and 12 is equal to 3 : 1
Or ratio of 12 to y is 1 : 3
Option B is the answer.
Answer:
∠F = 50°
Step-by-step explanation:
The sum of all three angles in a triangle = 180°
∠F = 180° - 30° - 100° = 50°
