What is the value of 2/3(x-6)-Y when x = 9 and y = 5/6?

Answers

Replace x and y with the given values:

2/3(9-6) - 5/6

Simplify:

2/3(3) - 5/6

Multiply:

2 - 5/6

Subtract:

1 1/6

Answer 1 and 1/6

The required simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

To find the value, substitute the given values of x and y into the expression:

2/3(x - 6) - y

= 2/3(9 - 6) - 5/6

= 2/3(3) - 5/6

= 2 - 5/6

To subtract fractions, you need a common denominator:

= 12/6 - 5/6

= 7/6

Therefore, the simplified value of 2/3(x-6)-Y when x = 9 and y = 5/6 is 7/6.

Consider the function shown. How can you restrict the domain so that f(x) has an inverse? What is the equation of the inverse function?

Answers

The correct option is D f⁻¹(x) = 2 + √(x + 2).

What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The inverse function of a function f in mathematics is a function that reverses the operation of f.

The given function is f(x) = 1 / (2 + √(x + 2)). The inverse function of the given function is,

f⁻¹(x) = 2 + √( x + 2).

Therefore, the correct option is D f⁻¹(x) = 2 + √( x + 2 ).

equation of line M is Y=5/8x+1 . Line N is perpendicular to M. What is the slope of line N?

Answers

Step-by-step explanation:

the slope of a line is always the factor of x in the equation. in our case here : 5/8.

the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).

the perpendicular slope (crosses the original line in a right angle = 90 degrees) turns x and y upside-down and flips the sign.

so, in our case, it is -8/5.

Choose the correct item from each drop-down menu to factor the trinomial 3x2 + 13x – 10 by grouping.

Answers

The factors of the given trinomial are (3x-2)(x+5).

What is trinomial?

Trinomial is a polynomial having 3 terms. At least one variable and one operation (addition, subtraction, multiplication, division) must be present in an algebraic expression.

Given is a trinomial 3x²+13x-10, we need to factorize it,

So,

= 3x²+13x-10

To factorize a trinomial, we do find the product of the product of a and c (ax²+bx-c) and find its two factors so that we can add or subtract so that we can find the middle term (b) of the trinomial,

Here,

a = 3, c = 10

a × c = 30

Now,

15 and 2 are the factors of the 30, also 15 - 12 = 13 which is the middle term of the trinomial,

Therefore,

3x²+13x-10 = 3x²+15x-2x-10

= 3x(x+5)-2(x+5)

= (3x-2)(x+5)

Hence, the factors of the given trinomial are (3x-2)(x+5).

The graph of a function is shown on the grid.
Which ordered pair best represents the location of the y-intercept?

Answers

Answer:

y-intercept = (0, -2)

Step-by-step explanation:

The y-intercept is the y-coordinate of the point (0, b) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at your graph, it shows that the line crosses at point (0, -2).

Therefore, the correct answer is (0, -2).
