The inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.

<h3>What is inequality?</h3>

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let's assume that the number would be x

The sum of a number and -4 is at least 8

According to the given question, translate the phrase into an algebraic form :

x - 4 ≥ 8

Add 4 both sides of the above inequality,

x - 4 + 4 ≥ 8 + 4

x ≥ 12

Therefore, the inequality x - 4 ≥ 8 represents the sentence " the sum of a number and -4 is at least 8" and the solution of the inequality is the value of variable x is x ≥ 12.

If (x/100-1)(x/100+1)=kx^2-1 k=

Artist 52 [7]

(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001

The latte is covered with a milk foam heart is covering 55 square cm of the coffee, then what is the area of the coffee NOT cove

Marysya12 [62]

Answer:

Step-by-step explanation:

The latte is what covered the coffee, Caffe latte is a coffee drink made with espresso and steamed milk, and this latte do form heart on the coffee, then we are told that the area of the latte heart is 55cm²

Then, space where latte is not form has a diameter 4cm

Then the radius is diameter divided by 2

r=d/2

r=4/2 =2

Then area of the circle which for the surface for the coffee is πr²

A=πr²

A=3.142×2²

A=12.568cm².

Area of coffee not covered is

55-12.568=42.432cm²

What is the linear function equation represented by the graph?<br><br><br> f(x)=______________

Katen [24]

The linear function equation represented by the graph is $\boxed{y = - \frac{1}{2}x + 1}.$

Further explanation:

The linear equation with slope $m$ and intercept $c$ is given as follows.

$\boxed{y = mx + c}$

The formula for slope of line with points $\left( {{x_1},{y_1}} \right)$ and $\left( {{x_2},{y_2}} \right)$ can be expressed as,

$\boxed{m = \frac{{{y_2} - {y_1}}}{{{x_2} - {x_1}}}}$

Given:

Explanation:

From the graph it has been observed that the line passes through the points $\left( {0,1} \right)$ and $\left( {2,0} \right).$

The line intersect y-axis at $\left( {0,1} \right).$

Therefore, the y-intercept is 1.

The line the line passes through the points $\left( {0,1} \right)$ and $\left( {2,0} \right).$

The slope can be obtained as follows,

$\begin{aligned}m&=\frac{{0 - 1}}{{2 - 0}}\\&= \frac{{ - 1}}{2}\\\end{aligned}$

The slope of the line is $- \dfrac{1}{2}.$

Substitute $- \dfrac{1}{2}$ for m and 1 for c in equation $y = mx + c$ to obtain the equation of the line.

$y = - \dfrac{1}{2}x + 1$

The linear function equation represented by the graph is $\boxed{y = - \frac{1}{2}x + 1}.$
