Answer:

a. m<CBA = m<DBA because of the definition of an angle bisector (angle bisector cuts the angle in half) We are also told that segment BD and Segment BC are congruent.

We don't know if segment AC and AD are congruent so we can't say those angles (the other two) are congruent.

b. point A and B will stay fixed because they are colinear to segment AB (on the same line)

c. Those two are needed because If those are true we can prove that they are congruent by SAS (Side Angle Side)

d. the reflection an prove that the lines and angles are congruent.

The expressions p-0.15p can be can be used to calculate the final cost of an item that has a price of p and is discounted 15%. W

lora16 [44]

Answer:

The original cost is $19.55

Step-by-step explanation:

What we want to do here is calculate the final cost, given the original price

What we have to do here is to substitute the value of $23 for p

This we have as;

23-0.15(23)

= 23-3.45

= $19.55

HELP ASAP 40 POINTS

AleksandrR [38]

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

$r=a_2-a_1$

$r=-12-(-8)$

$r=-12+8$

$r=-4$

The nth term of an AP is

$a_n=a+(n-1)d$

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

$a_n=-8+(n-1)(-4)$

$a_n=-8-4n+4$

$a_n=-4-4n$

Putting n=52, we get

$a_{52}=-4-4(52)$

$a_{52}=-4-208$

$a_{52}=-212$

Therefore, the equation for the nth term of the given sequence is $a_n=-4-4n$ and the 52nd term of the sequence is -212.

Yuri [45]

If the length is 32 and the ratio is 3:4, you'd do 32 ÷ 4 = 8. The answer is 3 × 8, which is 24 inches. I hope this helps!

Write an equation of the line that passes through the given point and is (a) parallel and (b)

viktelen [127]

Answer:

parallel line: y=-3x+14

perpendicular line: y=1/3x +2/3

Step-by-step explanation:

For the parallel line, use the point-slope formula to find the equation of the parallel line (since the slope is the same as the given line and the point (4,2) is given. For the perpendicular line, use the opposite reciprocal of the slope of the given line and use the point-slope formula again. The point-slope formula is Y-Y1=m(X-X1)
