Answer 1

Answer:

1) y = -1.5x - 1     ||   2) y = -1.5x + 1    ||  3. D ( 2 , -8 )

Step-by-step explanation:

1)

two coordinates: ( 0 , -1 ) , ( 2 , -4 )

slope = ( y2-y1 )÷(x2-x1) = (-4--1)÷(2-0) = -1.5

then find equation using: y - y1 = m ( x - x1 )

                                        : y - - 1 = -1.5 ( x - 0 )

                                        : y = -1.5x - 1

2)

two coordinates: ( 0 , 1 ) , ( -2 , 4 )

slope = ( 4 - 1) ÷ (-2-0) = -1.5

Find equation using y = mx +b ........where m is slope and b is y-intercept

y = -1.5x + 1

3)

y + 8 = 3(x -2 )

y = 3x -14  ..........main equation in slope intercept form.

A)

y = 3(-2)-14

y = -20 .therefore option A is incorrect

B)

y = 3(8)-14

y = 10 .therefore option B is incorrect

C)

y = 3(-8)-14

y = -38.therefore option C is incorrect

D)

y = 3(2)-14

y = 6 -14

y = -8 . therefore it matches and is correct answer.

the line crosses D( 2 , -8 )

Answer 2

As per your questions,

IMAGE 1 :-

The equation is

[tex]y = - \frac{3}{2}x - 1[/tex]

(Explanation attached as 1st image. Check it!)

IMAGE 2 :-

The equation is

[tex]y = - \frac{3}{2}x + 1 [/tex]

(Explanation attached as 2nd image. Check it!)

IMAGE 3 :-

When the point is (2,-8)

[tex]y + 8 = 3(x - 2)[/tex]

[tex] = > - 8 + (- 8) = 3 \times (2 - 2)[/tex]

[tex] = > 0 = 0[/tex]

Therefore, (2,-8) is true.

So, the answer is the option (2,-8)

HCF and LCM Questions

Responses:

6. (i) 27

(ii) 4 rose stalks, 3 lily stalks, and 2 orchid stalks

7. After 18 minutes

8. (i) May 7th

(ii) Every 12 days

How can the HCF and LCM be used to find the right responses?

6. The number of stalks of roses = 108

Number of stalks of lilies = 81

Number of stalks of orchids = 54

(i) The largest number of baskets that can be packed is given by the

Highest Common Factor, GCF , or HCF,  of  108, 81, and 54, which is

found as follows;

54 = 2 × 27

81 = 3 × 27

108 = 4 × 27

Therefore;

The HCF of 108, 81, and 54 is 27

Which gives;

The largest number of baskets that can be packed = 27

(ii) From the above factors, we have;

Number of rose stalks per basket = 4Number of lilies per basket = 3Number of orchids per basket = 2

7. Length of the circular path = 1 km. = 1,000 m.

Time Lixin takes to walk one round = 18 minutes = 1,080 seconds

Time Khairul takes to run one round = 360 seconds

Time Devi takes to cycle 2 rounds = 4 minutes

Therefore;

Time Devi takes to complete 1 round = [tex]\frac{4}{2}[/tex] = 2 minutes = 120 seconds

Required:

The time at which the three of them will next meet at the starting point

Solution:

The time at which they meet at the starting point is given as the lowest

common multiple, LCM of 1,080, 360, and 120, which is given as

follows.

1,080 = 360 × 3

1,080 = 120 × 9

1,080 = 1,080 × 1

Therefore;

The LCM of 1,080, 360, and 120 is 1,080

The time they will next meet at the starting point is after 1,080 seconds which is 18 minutes

8. The days off of Nora = Every 4 days

Days off for Amirah = Every 6 days

Nora's last day of = 29 April

Amirah's last day off = 1 May

(i) The next time they will both have the same day off is given as follows;

6·x = 2 + 4·x

2·x = 2

x = 1

Therefore, the next time Amirah has a day off, which is 1 May + 6 days = 7 May, they will both have the same day off.

They will both have the same day off on May 7

(ii) The number of days that it will take for them to have the same day off is given by the HCF of 4 and 6, which is every 12 days.

What is 80% of 60? Help meeeee

Answer:

48

Step-by-step explanation:

Divide 60 by 100 to get 1% of 60.

0.6

Multiply 0.6 by 80 to get 80%

48

48 is 80% of 60.

Answer:[tex]48[/tex]

Step-by-step explanation:

What is 80% of 60?

To get the answer,

First, convert the percentage to decimal form. How? Change the percent sign to decimal point. Then, move the decimal point two (2) places towards the left side of 80. It looks like this:

[tex]80 / 80.[/tex]

[tex]80. 80[/tex] decimal point moves two places to the left

Therefore, 80% is equal to 80 .

Then, let's solve!

Multiply  60 by  0.80 to get the answer.

60x0.80=48

From here, we get to know that the 80% of 60 is 48.

What is X equal to? It’s not 180 -.-

Answers

Answer:

x = 163

Step-by-step explanation:

(x-5)+22= 180

x = 143

hope this helps!!!

Answer:

x = 163

Step-by-step explanation:

It is 180 and there is no doubt in it. a straight line always measures 180 and this is a straight line not even curved

to find the value of x

x - 5 + 22 = 180

x + 17 = 180

x = 180 - 17

x = 163

we can even cross check

163 - 5 + 22

158 + 22

= 180

if the line wasn't 180 I wouldn't able to cross- check

c) Work out the size of angle z.​

Answers

Answer:

see explanation

Step-by-step explanation:

x = 65° ( vertically opposite angles )

y = 71° ( alternate angles )

The sum of the 3 angles in a triangle = 180° , then

x + y + z = 180° , that is

65° + 71° + z = 180°

136° + z = 180° ( subtract 136° from both sides )

z = 44°

So x = 65°, y = 71° , z = 44°

what is -7+4m+10=15-2m=

Answers

Answer:

m=2

Step-by-step explanation:

Add the numbers

-7+4m+10=15-2m

3+4m=15-2m

Rearrange terms

3+4m=15-2m

4m+3=15-2m

Rearrange terms

4m+3=15-2m

4m+3=-2m+15

Subtract 3 from both sides of the equation

4m+3=-2m+15

4m+3-3=-2m+15-3

Simplify

4m=-2m+12

Add 2m to both sides of the equation

4m=-2m+12

4m+2m=-2m+12+2m

Simplify

6m=12

Divide both sides of the equation by the same term

6m = 12

6m/6 = 12/6

Simplify

m = 2

Henry David Thoreau was a writer and philosopher. He was a major figure in the transcendentalist movement. Transcendentalists feel a deep connection to nature. They believe people connect directly with God and are born with innate goodness. For two years, Thoreau lived in a small cabin he built in the woods. He felt people should live closer to nature instead of relying on material wealth. Solitude is an essay from his book Walden; of, Life in the Woods. This is a delicious evening, when the whole body is one sense, and imbibes delight through every pore. I go and come with a strange liberty in Nature, a part of herself. As I walk along the stony shore of the pond in my shirt sleeves, though it is cool as well as cloudy and windy, and I see nothing special to attract me, all the elements are unusually congenial to me. The bullfrogs trump to usher in the night, and the note of the whippoorwill is borne on the rippling wind from over the water. Sympathy with the fluttering alder and poplar leaves almost takes away my breath; yet, like the lake, my serenity is rippled but not ruffled. These small waves raised by the evening wind are as remote from storm as the smooth reflecting surface. Though it is now dark, the wind still blows and roars in the wood, the waves still dash, and some creatures lull the rest with their notes. The repose is never complete. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear.
