If X:Y = 4:5 and x+y=144, then the values of x and y respectively are
A= 74 and 70
B= 70 and 74
C= 80 and 64
D= 64 and 80​

Answer:

y= -2x +2

Step-by-step explanation:

The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.

To find the value of m, use the gradient formula below:

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]

[tex]m = \frac{6 + 4}{ - 5} [/tex]

[tex]m = \frac{10}{ - 5} [/tex]

m= -2

Substitute m= -2 into the equation:

y= -2x +c

To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).

y= -2x +c

When x= 3, y= -4,

-4= -2(3) +c

-4= -6 +c

c= -4 +6

c= 2

Thus, the equation of the line is y= -2x +2.

Answer:

9 cm

Step-by-step explanation:

r = 3cm

Volume of cone = 27π cm³

[tex]\frac{1}{3}\pi r^{2}h=27\pi \\\\\frac{1}{3}*\pi *3*3*h=27\pi \\[/tex]

                   h   = [tex]\frac{27\pi *3}{\pi *3*3}\\[/tex]

take 17(2) for booth sides.

Which you will get 34.

58-34=24

Now you know that the remainder is the two vertical sides.

Step-by-step explanation:

Answer: $5

Step-by-step explanation:

Let the small candy be represented by x.

The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x

The large candy was $5 more than the medium candy. This will be: = 2x + 5

Since Jason spent a total of $30 on

candy, the cost of the small candy will be:

x + 2x + 2x + 5 = 30

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/5

x= 5

The small candy cost $5

Answer: 45

Step-by-step explanation:

59 + 76= 135

180-135= 45

Answer:

m∠1 = 45 degrees

Step-by-step explanation:

All triangles have the interior angle of 180

to find the missing angle, take the known angles and add them together:

76 + 59 = 135

then take the sum and subtract it from 180:

180 - 135 = 45

Answer:

£ 5400

Step-by-step explanation:

P = £ 7500

r = 12% = 0.12

t = 6 years

Simple Interest = P*r*t

                         = 7500 * 0.12 * 6

                         = £ 5400

Answer:

Not a function

Step-by-step explanation:

there's two 9's

Answer:

Part A: B) 3

Part B: $40

4. -1

7. 5x + 6y

8. Part A: y = 20x

8. Part B: $300

9. e > 12000 pounds

Step-by-step explanation:

Part A: x = 5t + 5

20 = 5t +5

15 = 5t

t = 3

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

4. 24 - 5^2

24 - (5*5)

24 - 25 = -1

7. 2x + 4y + 5 + 2y - 5 + 3x

2x + 3x = 5x

4y + 2y = 6y

5 + (-5) = 0

5x + 6y

8. Part A:

Total = y

Lawns = x

Amount = $20

so y = 20x

8. Part B:

y = 20x

y = 20(15)

y = 300

9. The elephant weighs more than 12000 pounds

Elephant = e

Answer:

x = 70°

Step-by-step explanation:

the interior angle which is supplemental to 140° is 40°

the sum of the interior angles of any triangle is 180°

so:

180° = 40° + 2x

subtract 40° from each side of the equation:

2x = 140°

x = 70°

Answer:

x  <= 8 ... you can buy a max of 8 fishes

6 books or more per month.

Step-by-step explanation:

Given the information provided, we can create the following inequality which multiplies the cost per fish ($7) by the number of fish we can buy (x) and it has to be less than or equal to $56

7x <= 56

We can now solve this inequality by isolating x

7x <= 56  ... divide 7 on both sides

x  <= 8   ... you can buy a max of 8 fishes

-----------------------------------------------------------------------------------------------------------------

13x > 68  ... divide both sides by 13

x > 5.23

Since the number of books needs to be a whole number then we round this decimal up to 6. Meaning that you must read 6 books or more per month.

Answer:

38% of the beads are red

Step-by-step explanation:

Given

Slope (m1) = 4

As it is said that the lines are perpendicular so we have

m1 * m2 = - 1

4 * m2 = - 1

m2 = - 1/4

The slope of the line perpendicular to line m is

- 1/4

Hope it will help :)❤

Answer:

The slope of the perpendicular line is -1/4

Step-by-step explanation:

Perpendicular lines have slopes that multiply to -1

Let the slope of the perpendicular line have sloe p

m*p = -1

4 * p = -1

Divide each side by 4

p = -1/4

The slope of the perpendicular line is -1/4
