What is the opposite rational number of -3/2

Check the picture below.

Yes, the equation:

y = 8

describes a function.

A function is a relation that maps elements x into elements y, such that each element x is mapped into a single value of y.

In this case, we have the equation:

y = 8

So all our points are of the form (x, 8).

Notice that all the inputs x are mapped into a single output y = 8, then this relation is a function.

The rate that Joe’s distance from the start of the path is changing with respect to time, in yards per minute is; 1.91 yards per minute

We are given the equation that represents Joe’s distance from the start of the path as;

D = 4s²/(5s + 10)

where;

D is distance measured in yards.

s is the total number of steps Joe has taken.

When s = 200, we have;

D = 4(200²)/(5(200) + 10)

D = 158.4158 yards

We are old that the constant rate is;

s/t = 100 steps per minute

From conversion rates, we know that , we know that;

1 step = 0.83 yards

Thus; 100 steps per minute = 83 yards per minute

The point slope form of the equation of the line that passes through the points (6, -9) and (7, 1) is y - 1 = 10(x - 7)

Linear equation can be represented in different form such as point slope form, slope intercept from, standard form and general form.

The line passes through the points (6, -9) and (7, 1). The point slope form can be represented as follows:

y - y₁ = m(x - x₁)

The equation of the linear relationship in slope-intercept form is: y = 2/3x + 50/3.

The equation in slope-intercept form for a linear relationship can be expressed as y = mx + b, where the slope is m and the y-intercept is b.

Using two points on the graph, (20, 30) and (50, 50), find the slope:

Slope (m) = change in y / change in x = (50 - 30) / (50 - 20)

Slope (m) = 20/30

Slope (m) = 2/3.

Find the y-intercept (b) by substituting m = 2/3 and (x, y) = (20, 30) into y = mx + b:

30 = 2/3(20) + b

30 = 40/3 + b

30 - 40/3 = b

50/3 = b

b = 50/3

An absolute value function is a function in algebra where the variable is inside the absolute value bars. This function is also known as the modulus function and the most commonly used form of the absolute value function is f(x) = |x|, where x is a real number. Generally, we can represent the absolute value function as, f(x) = a |x - h| + k, where a represents how far the graph stretches vertically, h represents the horizontal shift and k represents the vertical shift from the graph of f(x) = |x|. If the value of 'a' is negative, the graph opens downwards and if it is positive, the graph opens upwards.

The value of x for which (-1, 4) and (x, -2) make a slope of m = 5/4 is - [tex]\frac{29}{5}[/tex]

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

equation of straight line is y = mx + c

when x = -1, y = 4, m = 5/4

so that

4 = -1(5/4) + c

c = 4 + 5/4

4 can be written as fraction as 16/4

c = 16/4 + 5/4

Adding the numerator

c = 12/4

at x = x, y = -2

substituting

-2 = x( 5/4) + 21/4

-2 = 5x/4 + 21/4

-2 = [tex]\frac{5x + 21}{4}[/tex]

cross multiplying

5x + 21 = -8

How to find the ages of a person ?

Consider the difference between the individual's birthdate and the present day: days = current day - birth date. Age = (years 365) + (months 31) + days should be replaced with these variations. The individual's age is expressed in days. To get the age in years, divide the outcome by 365.

Let present age of melody be y and her sister age be x

Four years ago  age of Melody be (y - 4) and her sister age be (x - 4)

After six years age of Melody be (y + 6) and her sister age be (x + 6)

∴ [tex]\frac{(x-4)}{4} = (y - 4)[/tex]

[tex]\frac{(x+6)}{2} = (y + 6)[/tex]

The equation becomes

x + 6 = 2y + 12

x = 2y +6  ⇒ (1)

x - 4 = 4y -16

x = 4y - 12 ⇒(2)

Solving (1) and (2)

x - 2y = 6

x - 4y = -12

  2y = 18

    y = 9

Substituting the value of y in eq(1)

x = 2*9 + 6

x = 18 +6

x = 24

Let xy be the two digit number.

x + y = 12

So y = 12 - x

Substitute 12-x for y:

10x + y = 5y - 6

10x + 12 - x = 5(12-x) - 6      [Substituted 12-x in place of y]

9x + 12 = 60 - 5x - 6
