Answer:

Transversal/Parallel/Perpendicular

Step-by-step explanation:

What types of lines intersect and are coplanar?

Coplanar Lines

Three types of lines that are coplanar are parallel lines, perpendicular lines, and transversals. These all exist in a single plane, unlike skew lines (which exist in multiple planes). Any two lines in a plane must necessarily either be parallel or intersect.

Step-by-step explanation:

Answer:

-8x + 12

Step-by-step explanation:

It is asking us to simplify.  Therefore, we multiply the terms. -4(2x - 3) =

- 8x + 12

Answer:

-8× + 12

Step-by-step explanation:

-4x (2x - 3) simplify

Apply the distributive property

-4 (2x) - 4 × -3

multiply 2 by -4

-8x -4 × -3

multiply -4 by -3

= -8x + 12

54

Step-by-step explanation:

180-72=108

108/2=54

Answer:

The expression for Simon's age in terms of the variable m would indicate that Simon's age is equal to four times Marcie's age plus 3:

s=4m+3 (1)

Also, you know that the sum of their ages is 58, which is:

s+m=58 (2)

You can replace (1) in (2) and solve for m to find Marcie's age:

4m+3+m=58

5m=58-3

5m=55

m=55/5

m=11

Finally, you can replace m in (1) to find Simon's age:

s=4(11)+3

s=44+3

s=47

According to this, Marcie is 11 years old and Simon is 47 years old.

Given:

The population of continent of South America in 2010 is 395, 280, 204.

To find:

The closest estimate of this number.

Solution:

We have,

[tex]Population = 395, 280, 204[/tex]

The approximate value of this number is

[tex]Population \approx 400, 000, 000[/tex]

The scientific form of this value is

[tex]Population = 4\times 10^8[/tex]

Therefore, the correct option is C.

[tex].....................part \: 1. \: a.......................... \\\boxed{ Perimeter} \\ the \: perimeter \: of \: a \: triangle \: is \: given \: by \to\\ \boxed{p} = a + b + c........ \\ were \: \\ a \: b \: and \: c \: are \: the \: sides \: \: of \:the \: triangle \: when : \\ a = su = \: ?\\ b = ut = 8 \: units\\ c = ts = 14 \: units\\ to \: find \: su \: we \: apply \: pythagorean \: rule\: \to \: \\ (su) {}^{2} = {(ut)}^{2} + {(ts)}^{2} \\ su = \sqrt{ {8}^{2} + {14}^{2} } \\ su = 2 \sqrt{65} \\ hence : \\ \boxed{p} = 8 + 14 + 2 \sqrt{65} \\ p = 22 + 2 \sqrt{65} \\\boxed{p= 38 .12\: units}\\ \\ .......................part \: 1. \: b....................... \\ \boxed{Area} \\ the \: area \: of \: a \: triangle \: is \: given \: by : \\ A = \frac{1}{2} bc \\ hence : \\ A = \frac{1}{2} \times 8 \times 14 \\ \boxed{ A = 56\: {units}^{2}}[/tex]

Note.......I took care of part 1 only......cos handling both questions on here will be much on me

or.......you can set part 2 as a different question......but applying the same methods for the triangle will definitly work for the rectangle.

Answer:

[tex](x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )[/tex]

Step-by-step explanation:

Given

[tex]\left(\frac{x_1+\:x_2}{2},\:\:\frac{y_{1\:}+y_2}{2}\right)\:=\:\left(x_m,\:y_m\right)[/tex]

Required

Determine x2, y2

Start by splitting the expression

[tex]x_m = \left(\frac{x_1+\:x_2}{2})[/tex] and [tex]y_m = (\frac{y_{1\:}+y_2}{2})[/tex]

Solving for x2 in [tex]x_m = \left(\frac{x_1+\:x_2}{2})[/tex]

Multiply through by 2

[tex]2 * x_m = \frac{x_1 + x_2}{2} * 2[/tex]

[tex]2x_m = x_1 + x_2[/tex]

Make x2 the subject;

[tex]x_2 = 2x_m - x_1[/tex]

Similarly:

[tex]y_m = (\frac{y_{1\:}+y_2}{2})[/tex]

Multiply through by 2

[tex]2 * y_m = \frac{y_1 + y_2}{2} * 2[/tex]

[tex]2y_m = y_1 + y_2[/tex]

Make y2 the subject;

[tex]y_2 = 2y_m - y_1[/tex]

Hence:

[tex](x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )[/tex]

Answer:

Sub to SZ Lexrn if that does not show search up shiyo on vr and first vid is them please help out , thx bye . If you do it cmt and ill make a post for yall for 100 points

Step-by-step explanation:

Please, srry for sp

Answer:

The answer is c

4 multiples : 4 8 12 16 20 24 28 32 36 40 44 48

6 multiples: 6 12 18 24 30 36 42 48

what they dont have in comman 4,8,16,20,28, 32,40,44,

dock = 90°

boat = 40°

Thus the other angle equal 50°

I call that angle JJ

So ; JJ = 50°

_________________________________

According to the case of the Sine :

[tex] \frac{rope}{ \sin(50) } = \frac{25.17}{ \sin(40) } \\ [/tex]

[tex] \frac{rope}{ \cos(40) } = \frac{25.17}{0.643} \\ [/tex]

[tex] \frac{rope}{0.766} = \frac{25.17}{0.643} \\ [/tex]

[tex]rope = 0.766 \times \frac{25.17}{0.643} [/tex]

[tex]rope = 0.766 \times 39.14[/tex]

[tex]rope = 30.37[/tex]

[tex]rope = 30[/tex]

And we're done...

Answer:

b y= 3x+6 is the ans but not sure

Answer:

point m,

Step-by-step explanation:

if you reflect across the x axis then its the same point but in the negatives for y.

sry if its wrong I havent done these in a while

Answer:

M is the answer

Step-by-step explanation:

If you count the space between c and the x axis its 5 spaces so just do that on the other side and double check to make sure too.

Answer:

24

Step-by-step explanation:

what is the smallest number which is a multiple of both 8 and 12? so, an multiple of 8 must have 2 as a factor at least 3 times. Similarly, multiples of 12 have at least two 2's and one 3. so we need 2x2x2x3 or 24 if every factor is to be included.

I'm not the best at explaining but you can search google to get the better Idea.

(btw this is for the fist question)

Answer: can you explain what you mean because its just numbers

Answer:

28

Step-by-step explanation:

12 - c - 12 = -16 - 12

-C = -28

-C divided by -1 = -28 divided by -1

c = 28
