The best and most correct answer among the choices provided by your question is the second choice or letter B. The slope of line CD is undefined.

By two-point slope form:
m=(y2-y1)/(x2-x1)
m=(8+7)/(4-4)
m=15/0 (undefined)

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Give a direct proof that the sum an even integer and an odd integer is odd.

mina [271]

Even integer: 2 x a, where a is a natural number without 0;
Odd integer : 2 x b + 1 , where b is a natural number;
So, 2 x a + 2 x b+ 1 = 2 x ( a + b ) + 1, which is an odd integer.

Find the measure of Angle B A. 50° B. 55° C. 60° D. 65°

kondaur [170]

Option B. 55° is the correct answer

Step-by-step explanation:

"The sum of interior angles of a triangle is always 180°"

Given

m∠A=(3x+1)°

m∠B=(2x-1)°

m∠C = 40°

We know that

m∠A+m∠B+m∠C=180°

Putting the values of angles

$(3x+1) +(2x-1) +40 = 180\\3x+1+2x-1+40 = 180\\5x+40=180\\$

Subtracting 40 from both sides

$5x+40-40=180-40\\5x=140$

Dividing both sides by 5

$\frac{5x}{5} = \frac{140}{5}\\x=28$

We have to find Angle B,

m∠B = 2x-1 = 2(28)-1 = 56-1 = 55°

Hence,

m∠B=55°

Option B. 55° is the correct answer

A jewelry box is b2 inches long, 3c2 inches wide, and 2c1 inches tall. Which of the following are correct? Select ALL that apply

Mariulka [41]

9514 1404 393

Answer:

B, F

Step-by-step explanation:

The volume is the product of the dimensions:

V = LWH

V = (b^2)(3c^2)(2c^1) = (3·2)(b^2)(c^(2+1))

V = 6b^2·c^3 . . . . . matches B

For b=3 and c=2, the volume is ...

V = 6(3^2)(2^3) = 6(9)(8)

V = 432 . . . . cubic inches . . . . matches F
