Answer 1

Answer:

D(5, 4), E(14, 7), M(9.5, 5.5)

Step-by-step explanation:

As AD = 1/4AB and DE ║ AC, the ratio CE/CB = 1/4, or CE = 1/4CB

Find the coordinates of D:

x = 1 + 1/4(17 - 1) = 1 + 4 = 5y = 5 + 1/4(1 - 5) = 5 - 1 = 4

Find the coordinates of E:

x = 13 + 1/4(17 - 13) = 13 + 1 = 14y = 9 + 1/4(1 - 9) = 9 - 2 = 7

Find the coordinates of the midpoint M of DE:

x = (5 + 14)/2 = 19/2 = 9.5y = (4 + 7)/2 = 11/2 = 5.5

Original line: y = -5/6x - 1

A line that is parallel to the original will have the same slope. To find the new y-intercept, we'll take the original line, plug in the given point, and solve for b.

y = -5/6x + b

-2 = -5/6(5) + b

-2 = -25/6 + b

b = 13/6

Parallel Line: y = -5/6x + 13/6

A line that is perpendicular to the original will have the opposite reciprocal slope. To find the new y-intercept, we'll take our perpendicular slope, plug in the given point, and solve for b.

y = 6/5x + b

-2 = 6/5(5) + b

-2 = 6 + b

b = -8

Perpendicular Line: y = 6/5x - 8

According to above diagram :

RT = RS + ST

that is :

[tex]2x + 75 = 4x + 107 + 12[/tex]

[tex]2x - 4x = 119 - 75[/tex]

[tex] - 2x = 44[/tex]

[tex]x = - 22[/tex]

now, RT = 2x + 75

[tex](2 \times - 22) + 75[/tex]

[tex] - 44 + 75[/tex]

[tex]31[/tex]

hence , RT = 31 units

Answer:

RT = 31

Solve for x:

[tex]x=-22[/tex]

Step-by-step explanation:

==>> The sum of the line is RST

[tex]4x+107+12=RST[/tex]

==>> Since [tex]RST = 2x + 75[/tex], the equation will newly become [tex]4x+107+12=2x+75[/tex]

--

To find [tex]4x+107[/tex], we need to find the x.

==>> [tex]x=-22[/tex]

-- Lets check our work

==>> [tex]4(-22) = -88[/tex]

[tex]-88 + 107 = 19 [RS = 19][/tex]

[tex]RS + ST = 19 + 12 =[/tex] 31

Find the equation of a line parallel to y=2x-4 that contains the points (1,-1)

Answers

Answer:

y=2x-3

Step-by-step explanation:

refer to picture plz

Answer:

the desired equation is y = 2x - 3

Step-by-step explanation:

Parallel lines have the same slope.  Thus, a new line parallel to y = 2x - 4 has the slope 2.  

Find the equation of the new line by writing out the slope-intercept form

y = mx + b.  Substitute -1 for y and 1 for x:

-1 = 2(1) + b, which yields b = -3

Then the desired equation is y = 2x - 3

divide 0.63512 by 13.6​

Answers

Answer:

21.413

Step-by-step explanation:

Change the divisor 0.63512 to a whole number by moving the decimal point 5 places to the right. Then move the decimal point in the dividend the same, 5 places to the right.

We then have the equations:

1360000 ÷ 63512 = 21.413

and therefore:

13.6 ÷ 0.63512 = 21.413

Both calculated to 3 decimal places.

Find the value of x. Find the measures of the two supplementary angles

Answers

Answer:

x = 32

<1 = 102 degrees

Step-by-step explanation:

3x + 6 + 2x + 14 = 180

5x + 20 = 180

5x = 180 - 20

x = 160/5

x = 32

Answers

Answer:

[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]

Step-by-step explanation:

Basically, x is 2 times smaller than y, or

y is 2 times larger than x.

For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8

Another example:

When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6

I don't know which one you're looking for, but try putting in

=====================================================

Explanation:

Parallel lines always have equal slopes, but different y intercepts. For example, the two lines y = 3x+5 and y = 3x+7 have a slope of 3. Refer to y = mx+b where m is the slope. Parallel lines never intersect.

-----------

For perpendicular lines, the two slopes always multiply to -1 assuming neither line is vertical nor horizontal. Consider the two linear equations

y = (1/2)x+5

y = -2x-7

The slopes 1/2 and -2 multiply to -1 which is enough to show that they are perpendicular lines. The two lines meet at a 90 degree angle.

To go from one slope to the other, we apply the negative reciprocal. That means we...

flip the fractionflip the sign

Applying the first step to 1/2 gets us 2/1 or 2. Then changing the sign has us go from 2 to -2. This process can be reversed.

-----------

For some of these equations, you'll need to rearrange things into either point-slope form or slope intercept form. This will allow you to read off the slope.

Point slope form is y-y1 = m(x-x1)

Slope intercept form is y = mx+b

For either case, all we care about is the variable m.

I'll show how problem 14 transforms into slope intercept form

x+2y = 14

2y = -x+14

y = (-x+14)/2

y = (-x/2) + (14/2)

y = (-1/2)x + 7

We see that m = -1/2 here. Anything parallel to this will have the same slope. The perpendicular slope is 2 after applying the negative reciprocal operation. Problems 13, 15, 16, 17, and 18 are going to follow similar steps.

The table shows the cost of movie tickets based on the number of tickets purchased. PLEASE HELP ME

Number of Tickets Cost

2 $17.00

3 $25.50

4 $34.00

5 $42.50

Based on this proportional relationship, find the constant of proportionality (r). Using the value for r, enter an equation that will calculate the cost (y) of x movie tickets in the form of y=rx. The answer is not y=8.5 Please help the one who gives me the correct answer will get brainliest

Answers

The proportional relationship is given by y = 8.5x

Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.

Let x represent the movie tickets and y represent the cost.

Since x and y are proportional, hence:

y ∝ x

y = rx

Where r is the constant of proportionality.

From the table to find x, when y = 17, x = 2, hence:

17 = 2r

r = 8,5

y = 8.5x

The proportional relationship is given by y = 8.5x

They both seem to really care for their kids and want whats best for them. Their parents are trying to teach them to be happier with themselves. American food traditions for Christmas Eve are more leaned towards roast turkey, ham, sweet potatoes, etc. But traditional Chinese foods are usually dumplings, huoshao, rice, fish, etc. Amys parents invite her crushes family over to Christmas Eve dinner, making Amy worried that her crush, Robert might judge her over her families poor manners and the food theyll have served. However Amys mother doesnt want her to feel the need to change just for some boy or to act like somebody shes not. She talks about how Amy could try acting and looking American on the outside but inside should always be Chinese, as she says but inside you must always be Chinese. In my mothers garden Kaitlyn is embarrassed over the fact she lives in poverty so she tries her best to hide it from everybody at school. Her mother decided to go back to college to get a degree, knowing thatll help her get a better job in education so she can get her and her daughters out of poverty housing. Her mother starts a garden so they have A little something to hold onto from their past lifes before poverty and her divorce. Shes also described to be a very honest person my mother is radically honest, one of the few people I know who is in capable of lying. Amys mother is a good role model because shes trying to teach Amy that its okay to be different and have other traditions. She tells Amy you must be proud you are different and your only shame is to have shame. Although Amy doesnt realize it at the time, her mother just wants her to be happy with herself. And Kaitlyns mother is a good role model because shes getting a better education so she can get her family out of poverty and hopefully back to being middle-class, she did not want us to stay in this housing project forever. Well shes also inspiring younger kids to help work on a little garden to lighten things up around there. Although some people may disagree, thanking their parents are bad role models. From Amys mother inviting Robert and his family over, while also making a very strange menu it embarrassed Amy because she liked Robert and didnt want him to think low of her. Tell her mother knew she liked rapper and probably just wanted to get to know him and his family. Or as Kaitlyns mom breaks the rules by keeping a computer even though poverty doesnt allow it. But she only kept it because its helpful for her and she didnt want to just throw it away.
