What is linear inequalities?

Linear inequality is an equation or expression that do not have a definite solution. Thus it consist of either of greater than, less than, greater than or equal to, less than or equal to etc.

In the given inequality question, we have;

8 is less than or equal to -3x +26

This can be expressed as;

8 ≤ -3x +26

so that collecting like terms,

8 - 26 ≤ -3x

-18 ≤ -3x

-18/ -3 ≤ x

6 ≤ x

Therefore, x ≥ 6.

Step-by-step explanation:

Yeah

Answer: \(y=-\frac{1}{2} x+4\)

Step-by-step explanation:

The given points are (2,3) and (-2,5). To find the equation, we should first find slope. To find slope, we use this formula \(y=\frac{y_2-y_1}{x_2-x_1}\).

\(y=\frac{5-3}{-2-2} =\frac{2}{-4}=-\frac{1}{2}\)

Now that we have the slope, we can plug in one of the points to find the y-intercept.

\(3=-\frac{1}{2} (2)+b\)          [multiply]

\(3=-1+b\)               [add both sides by 1]

\(b=4\)

Now we know the equation is \(y=-\frac{1}{2} x+4\).

Let y=f(x). To find the inverse of f, isolate x:

Let x=f^{-1](y). Then:

Evaluate the inverse of f at y=x:

Therefore, the rule of correspondence of the inverse of f is given by the expression:

If you examine the x point:

-1 became -1/5

That is , x coordinate divided by 5

If you examing the y point:

12 became 2 and 2/5, or 12/5

That is, y coordinate divided by 5

So, both the points are divided by 5, or hence, mutliplied by (1/5)th

Thus, the scale factor is:

The solution of the system of linear equations, is (1.167, 3.667).

Given that the system of linear equations, y = -2x+6 and y = 4x - 1, we need to find the solution for the same,

y = -2x+6............(i)

y = 4x - 1.......(ii)

Equating the equations since the LHS is same,

-2x+6 = 4x-1

6x = 7

x = 1.167

Put x = 1.16 to find the value of y,

y = 4(1.16)-1

y = 4.66-1

y = 3.667

Therefore, the solution of the system of linear equations, is (1.167, 3.667).

You can also find the solution using the graphical method,

Plot the equations in the graph, the point of the intersection of both the lines will be the solution of the system of linear equations, [attached]

Hence, the solution of the system of linear equations, is (1.167, 3.667).

Answer:

Answer for what?

Step-by-step explanation:

The coordinates of the point (4,4) after the transformation are given as follows:

(-1, 4).

The coordinates of the original point are given as follows:

(4,4).

The rule for a reflection over the y-axis is given as follows:

(x,y) -> (-x, y).

Meaning that the signal of the y-coordinate is changed.

Hence the coordinates of the reflected point are given as follows:

(-4,4).

As the signal of the original x-coordinate of 4 is changed.

The rule for a horizontal translation 3 units right is given as follows:

(x,y) -> (x + 3, y).

Hence the coordinates of the reflected and translated point are given as follows:

Answer:

initial speed (u)= 0m/s (at rest)

final speed (v)= 20m/s

time taken (t)= 2seconds

we have,

acceleration;a= (v-u)/t

=(20-0)/2

=10m/s²

Answer:

\(10\frac{m}{s^{2}}\)

Step-by-step explanation:

Let u = Initial speed \((\frac{m}{s})\)

     v = Final speed \((\frac{m}{s})\)

     t = time (seconds)

     a = Acceleration

According to this question:

\(u= 0 \frac{m}{s}\) (i.e starts at rest)

\(v = 20 \frac{m}{s}\)

\(t = 20s\)  

a = ?

\(a = \frac{v - u}{t}\)

  = \(\frac{20 \frac{m}{s} - 0\frac{m}{s}}{2s}\)

  = \(\frac{20\frac{m}{s}}{2s}\)

Acceleration= \(10\frac{m}{s^{2} }\)

0.63

Step-by-step explanation:

P(V or W) = P(V) + P(W) − P(V and W)

P(V or W) = 0.47 + 0.37 − 0.01

P(V or W) = 0.83

P(not W) = 1 − P(W)

P(not W) = 1 − 0.37

P(not W) = 0.63

a. the probability that the computer contains either a virus or a worm or both is 0.83

b. The probability that the computer does not contain a worm is 0.63.

(a)

The probability is

P(V or W) = P(V) + P(W) − P(V and W)

P(V or W) = 0.47 + 0.37 − 0.01

P(V or W) = 0.83

Freya should budget a maximum of $472.50 for housing expenses based on the guideline of spending 30% of her monthly income.

When budgeting for housing, it is generally recommended to allocate a certain percentage of your income towards housing expenses. The recommended percentage varies depending on factors such as location, personal financial goals, and individual circumstances.

A common guideline is to spend no more than 30% of your monthly income on housing expenses. To determine the maximum amount Freya should budget for housing, we can calculate 30% of her monthly income:

Maximum housing budget = 30% of $1575

Maximum housing budget = 0.30 × $1575

Maximum housing budget = $472.50

Therefore, Freya should budget a maximum of $472.50 for housing expenses based on the guideline of spending 30% of her monthly income.

Answer:

See below for proof.

Step-by-step explanation:

Rearrange the given equation into a quadratic with terms in y:

\(\implies x^2=y^2+a\left(\dfrac{x-y}{a}\right)^2\)

\(\implies y^2+a\left(\dfrac{(x-y)^2}{a^2}\right)-x^2=0\)

\(\implies y^2+\dfrac{(x-y)^2}{a}-x^2=0\)

\(\implies y^2+\dfrac{x^2}{a}-\dfrac{2xy}{a}+\dfrac{y^2}{a}-x^2=0\)

\(\implies y^2+\dfrac{y^2}{a}-\dfrac{2xy}{a}+\dfrac{x^2}{a}-x^2=0\)

\(\implies \left(1+\dfrac{1}{a}\right)y^2-\left(\dfrac{2x}{a}\right)y+\left(\dfrac{x^2}{a}-x^2\right)=0\)

\(\boxed{\begin{minipage}{3.6 cm}\underline{Quadratic Formula}\\\\$x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$\\\\when $ax^2+bx+c=0$ \\\end{minipage}}\)

Therefore, comparing the quadratic:

\(a=\left(1+\dfrac{1}{a}\right)\)

\(b=\left(-\dfrac{2x}{a}\right)\)

\(c=\left(\dfrac{x^2}{a}-x^2\right)\)

Substitute the values of a, b and c into the formula:

\(\implies y=\dfrac{-\left(-\dfrac{2x}{a}\right) \pm \sqrt{\left(-\dfrac{2x}{a}\right)^2-4\left(1+\dfrac{1}{a}\right)\left(\dfrac{x^2}{a}-x^2\right)}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm \sqrt{\dfrac{4x^2}{a^2}-4\left(\dfrac{a+1}{a}\right)\left(\dfrac{x^2-ax^2}{a}\right)}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm \sqrt{\dfrac{4x^2}{a^2}-\dfrac{4(a+1)(x^2-ax^2)}{a^2}}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm \sqrt{\dfrac{4x^2}{a^2}-\dfrac{4x^2-4a^2x^2}{a^2}}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm \sqrt{\dfrac{4x^2}{a^2}-\dfrac{4x^2}{a^2}+\dfrac{4a^2x^2}{a^2}}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm \sqrt{4x^2}}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{2x}{a} \pm2x}{2\left(1+\dfrac{1}{a}\right)}\)

\(\implies y=\dfrac{\dfrac{x}{a} \pm x}{1+\dfrac{1}{a}}\)

\(\implies y=x\left[\dfrac{\dfrac{1}{a} \pm 1}{1+\dfrac{1}{a}}\right]\)

Case 1

\(\implies y=x\left[\dfrac{\dfrac{1}{a}-1 }{1+\dfrac{1}{a}}\right]\)

Add and subtract 1 from the numerator:

\(\implies y=x\left[\dfrac{1+\dfrac{1}{a}-1-1 }{1+\dfrac{1}{a}}\right]\)

\(\implies y=x\left[\dfrac{1+\dfrac{1}{a}-2 }{1+\dfrac{1}{a}}\right]\)

\(\implies y=x\left[\dfrac{1+\dfrac{1}{a}}{1+\dfrac{1}{a}} -\dfrac{2}{1+\dfrac{1}{a}}\right]\)

\(\implies y=x\left[1 -\dfrac{2}{1+\dfrac{1}{a}}\right]\)

Case 2

\(\implies y=x\left[\dfrac{\dfrac{1}{a}+1 }{1+\dfrac{1}{a}}\right]\)

\(\implies y=x\)

Answer:

(4k+5)+ (6k+10) = 115

Exterior angle of a triangle is equal to the sum of two opposite interior angles

10k=15=115

10k= 100

k = 100/10

k = 10

Step-by-step explanation:

Answer:

k = 10

Step-by-step explanation:

The 3rd angle that's not defined in the equation is supplementary to 115, so the angle is 180-115 = 65.

We can solve for the equation 65+(4k+5)+(6k+10)=180 -> 65+4k+5+6k+10=180 -> 10k+80 = 180 -> 10k = 100 -> k = 10.

To double-check(optional), we can plug k back into the equation, so 65 + 4*10 + 5 + 6*10 + 10 = 180 -> 100 + 65 + 5 + 10 = 180 -> 180 = 180, so we can confirm that k = 10.
