Answer:

(-11, -8)

Step-by-step explanation:

Reflection across the x-axis changes the sign of the y-coordinate.

For X(-11, 8), the reflected point is X'(-11, -8). (matches the last choice)

The answer=>

For this,we need to know what's Middle splitting method

In order to factorize x² + bx + c we have to find numbers p and q such that p + q = b and pq = c. After finding p and q, we split the middle term in the quadratic as px + qx and get desired factors by grouping the terms.

Step-by-step explanation:

$9x {}^{2} - 24x + 16 \\ = > 9x {}^{2} - 12x - 12x + 16 \\ = > 3x(3x - 4) - 4(3x - 4) \\ = > (3x - 4)(3x - 4) \\ so... \\ x = eitherway \: 4$

Alpha= Beta = 4

1. Using your straightedge, draw a reference line, if one is not provided.
2. Copy the side of the square onto the reference line, starting at a point labeled A'.
3. Construct a perpendicular at point B' to the line through ab2.
4. Place your compass point at B', and copy the side of the square onto the perpendicular b'g. Label the end of the segment copy as point C.
5. With your compass still set at a span representing AB, place the compass point at C and swing an arc to the left.
6. Holding this same span, place the compass point at A' and swing an arc intersecting with the previous arc. Label the point of intersection as D.
7. Connect points A' to D, D to C, and C to B' to form a square.

What is the median of 0.8, 1.0, 2.7, 2.8, 3.1, 13.3

tresset_1 [31]

Answer:

$2.75$

Step-by-step explanation:

Step 1: Determine the median

$0.8, 1.0, 2.7, 2.8, 3.1, 13.3$

The median of a set is the middle of the set. In this instance, we have 6 numbers so we don't have a number directly in the set representing the median. Instead, we need to find the average or middle between the 3rd and 4th number. So we take 2.7 and 2.8, add them together to get 5.5 and then we divide by 2 to get 2.75 which is our median.

Answer: $2.75$
