Step-by-step explanation:

The vertex of the function f(x) = x²+10 is (0,10). Correct option is (A).

Vertex form of equation is an alternate way of writing the equation of a parabola

The vertex form of an equation is
f(x)= a(x-h)²+k,

Here, h and k are constants

The given equation is,

f(x) = x²+10

To determine the vertex of the equation,

substitute x=0,

f(x)=0+10

f(x)=10

The vertex of the function f(x) is (0,10).

Answer:

There are 60 girls and 40 boys in the class.

Step-by-step explanation:

Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:

1 x 75 + 0 x 65 + 75

0.9 x 75 + 0.1 x 65 = 74

0.8 x 75 + 0.2 x 65 = 73

0.7 x 75 + 0.3 x 65 = 72

0.6 x 75 + 0.4 x 65 = 71

Thus, there are 60 girls and 40 boys in the class.

Answer:

For this case we can see the table as a set of ordered pairs.

We then have the following ordered pairs:

(-6, -7)

(-1,1)

(0, 9)

(3, -2)

Then, the domain of the function is represented by all the values of x.

We have then:

{x | x = –6, –1, 0, 3}

Answer:

{x | x = –6, –1, 0, 3}

Required

Solve:

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2[/tex]

Apply law of indices

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{4^3} * \frac{2^2}{3^2}[/tex]

Express 4 as 2^2

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{(2^2)^3} * \frac{2^2}{3^2}[/tex]

[tex](\frac{3}{4})^3 * (\frac{2}{3})^2 = \frac{3^3}{2^6} * \frac{2^2}{3^2}[/tex]

Express as a singe fraction

Answer:

y = -2x + 8

Step-by-step explanation:

(−6, 20) and (0, 8)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(8 - 20) / (0 - (-6))

Simplify the parentheses.

= (-12) / (6)

Simplify the fraction.

-12/6

= -2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.

8 = -2(0) + b

To find b, multiply the slope and the input of x(0)

8 = 0 + b

b = 8

Plug this into your standard equation.

y = -2x + 8

This is your equation.

Check this by plugging in the other point you have not checked yet (-6, 20).

y = -2x + 8

20 = -2(-6) + 8

20 = 12 + 8

20 = 20

Your equation is correct.

x = 4.5 + -0.5y

Step-by-step explanation:

The boundary line of the inequality is intersecting the x-axis at 4.5.

The given inequality is 4x + 2y < 18.

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Graph the inequality by finding the boundary line, and then shading the appropriate area.

Now, 4x + 2y < 18 can be written as y<−2x+9.

The boundary line of the inequality is given below.

The boundary line of the inequality is intersecting the x-axis at 4.5.
