the answer is b ots is not a ot c for sure

Answer:

A. Y = 144/x

Step-by-step explanation:

Inversely means y = 1/x

If y = 48, when x = 3

so 144/3 = 48

Therefore the answer is A

If the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

A relation is a function if it has only One y-value for each x-value.

If y varies inversely with x, it means that y is inversely proportional to x, or y=k/x, where k is a constant of proportionality.

To find k, we can use the given values of y and x:

y = k/x

48 = k/3

k = 144

Now that we know k, we can write the function that represents the relationship between x and y:

y = 144/x

Therefore, if the  value of y varies inversely with x then the function Y= 144/x represents the relationship between x and y if y = 48 when x = 3

Step-by-step explanation:

Answer:

r = 8

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to 3

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (r, 6)

m = [tex]\frac{6+6}{r-4}[/tex] = [tex]\frac{12}{r-4}[/tex] , then

[tex]\frac{12}{r-4}[/tex] = 3 ( multiply both sides by (r - 4))

12 = 3(r - 4) ← divide both sides by 3

4 = r - 4 ( add 4 to both sides )

8 = r

[tex]5^{12}[/tex]

Step-by-step explanation:

Lets say there's a number 'x' and there's an expression [tex](x^a)^b[/tex] where 'a' & 'b' are also numbers , the simplified form of the expression is [tex]x^{a \times b}[/tex].

So ,

[tex](5^4)^3 = 5^{4 \times 3} = 5^{12}[/tex]

Answer:

All the measurements are correct

Step-by-step explanation:

What we have here are right triangles

For right triangles, the square of the hypotenuse (the side facing the right angle) equals the sum of the squares of the two other sides

Starting from the left;

a) 13^2 = 12^2 + 5^2

169 = 144 + 25

169 = 169

This triangle is valid

b) 25^2 = 24^2 + 7^2

625 = 576 + 49

625 = 625

This triangle is valid

c) 5^2 = 3^2 + 2^2

25 = 9 + 16

25 = 25

Answer:

In first case it is (8+6) whole divided by 2 that is 8/2+6/2 where u will get the answer 7.

in next case it is (8/6) then divided by 2

which will be 8/6*1/2.

(while converting from division to multiplication remember to take the reciprocal of the number after division sign in this 2 will become 1/2)

so and will be 8/12. 2/3 will be the answer....

Answer:

30 degrees.

Step-by-step explanation:

A triangle has 180 degrees. The two base angles are 75 degrees each. The third angle is x

75 + 75 + x = 180          Combine like terms on the left

150 + x = 180                Subtract 150 from both sides.

-150         -150

x = 30

The third angle is 30 degrees.

Answer:

10 by 3

Step-by-step explanation:

When 4 by 3 water is sufficient to water 2 by 5 of the plants so the water i.e. required to water all the plants is 10 by 3

As here we multiply both the fractions by reciprocal the second fraction

So the water i.e. needed to water all plants is 10 by 3

Answer:

The slope of the line is 1

Step-by-step explanation:

Missing part of question

(a) (-3, 4) and (5, 4)

(b) (4, 5) and (4, -3).

Answer:

(a) (-3, 4) and (5, 4)

Zero slope

Horizontal line

(b) (4, 5) and (4, -3).

Undefined slope

Vertical line

Step-by-step explanation:

Solving (a): (-3, 4) and (5, 4)

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives

[tex]m = \frac{4-4}{5 - -3}[/tex]

[tex]m = \frac{0}{8}[/tex]

[tex]m = 0[/tex]

This line has a slope of zero.

When slope equals 0, then the line is horizontal

Solving (b): (4, 5) and (4, -3)

Slope (m) is calculated as:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives

[tex]m = \frac{5--3}{4-4}[/tex]

[tex]m = \frac{8}{0}[/tex]

m = undefined

This line has an undefined slope.

When the slope of a line is undefined, then the line is vertical

Answer:

x=8/3

Step-by-step explanation:

2(3-(2x+4))-5(x-7)=3x+1 (first distribute)

-9x+33=3x+1 (subtract 33 from both sides)

-9x=3x-32 (subtract 3x from both sides)

-12x =-32 (divide both sides by -12)

x=8/3
