By solving the system of equations, and seeing in which quadrant is each solution, we conclude that:

Here we get the following system of equations:

x^2 - y = 7

y - 5x = -11

If we isolate the same variable in both of the equations, then we can equate them, so I will isolate "y" in both of the equations of the system.

y = x^2 - 7

y = -11 + 5x

Now we can write:

x^2 - 7 = -11 + 5x

So we have the quadratic equation, this can be rewritten as:

x^2 - 7 + 11 - 5x = 0

x^2 - 5x + 4 = 0

Using the Baskhara's formula (or the quadratic formula), we will get the two solutions for x.

[tex]x = \frac{5 \pm \sqrt{(-5)^2 - 4*1*(4)} }{2*1}[/tex]

The solutions are:

[tex]x = \frac{5 \pm \sqrt{(9} }{2} \\\\x = \frac{5 \pm 3}{2}[/tex]

So we get:

x = (5 + 3)/2 = 4

x = (5 - 3)/2 = 1

Evaluating the linear equation in these values of x:

y = -11 + 5*4 = -11 + 20 = 9

y = -11 + 5*1 = -6

So we get the coordinate pairs (4, 9) which is on the first quadrant because both values are positive, and (1, -6) which is on the fourth quadrant because the x-value is positive and the y-value is negative.

The perimeter of a square having area of 36[tex]cm^{2}[/tex] is equal to 24cm

Square of area A= 36[tex]cm^{2}[/tex]

We know that a square is a quadrilateral( a closed figure with four sides) with all 4 sides equal in length. Let the measure of one side of a square be x. from the formula to find out the area of a square we know that

Area of a square A = [tex]x^{2}[/tex]

∴From the data given in the problem

[tex]x^{2}[/tex] = 36

⇒x = √36

⇒x = 6

∴The measure of one side of a square = x cm = 6 cm

We know that the perimeter of a square = x+x+x+x = 4x

∴The perimeter of the given square = 4x = 4 × 6 = 24cm

Hence we get by solving as done above that for a square of area 36cm^2

the perimeter of the square is 24cm

Answer:

Step-by-step explanation:

try and split the shape into 2 rectangles to picture it .

The required equation that is perpendicular to the line y = -¾ x - 14 and goes through the point (0, 13) is 3x + 4y = 52 .

Given equation is y = - 3/4 - 14

this is of the form y = mx + c

on comparing, m= - 3/4

And the points given are x = 0 and y =13

thus as we know that the equation of the line is

y - y₁ = m ( x- x₁ )

On substituting the values mentioned above we see that

y - 13 = - 3/ 4 ( x - 0 )

4 y - 52 = - 3 x

and on rearranging we get :

3x + 4y = 52

Thus the required equation that is perpendicular to the line y = -¾ x - 14 and goes through the point (0, 13) is 3x + 4y = 52 .

Answer: x = [tex]\frac{ \sqrt{7}-5}{2}[/tex]

              x = [tex]\frac{ -\sqrt{7}-5}{2}[/tex]

Step-by-step explanation:

[tex](2x + 5)^{2} - 7 = 0[/tex]

Add 7 to both sides of the equation.

[tex](2x + 5)^{2} - 7 + 7= 0 + 7[/tex]

Subtracting 7 from itself leaves 0.

[tex](2x + 5)x^{2} =7[/tex]

Take the square root of both sides of the equation.

[tex]2x + 5 = \sqrt{7} \\2x + 5 = -\sqrt{7}[/tex]

Subtract 5 from both sides of the equation.

[tex]2x + 5 - 5 = \sqrt{7} - 5 \\2x + 5 - 5 = - \sqrt{7} - 5[/tex]

Subtracting 5 from itself leaves 0.

[tex]2x = \sqrt{7} - 5 \\2x = - \sqrt{7} - 5[/tex]

Subtract 5 from [tex]\sqrt{7}[/tex].

[tex]2x = \sqrt{7} - 5[/tex]

Subtract 5 from [tex]-\sqrt{7}[/tex].

[tex]2x = -\sqrt{7} - 5[/tex]

Divide both sides by 2.

[tex]\frac{2x}{2} =\frac{ \sqrt{7}-5}{2} \\\frac{2x}{2} =\frac{- \sqrt{7}-5}{2}[/tex]

Dividing by 2 undoes the multiplication by 2.

[tex]x=\frac{ \sqrt{7}-5}{2}\\x=\frac{ -\sqrt{7}-5}{2}[/tex]

There are 32 natural numbers less than 200 that are divisible by 4 but not 3.

According to the solution of the fractions. Hiroko cuts her string into 6 equal-size pieces.

A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces.​The numerator and denominator of positive common fractions are both natural integers. The denominator shows how many of the numerator's equal parts make up a unit or whole, while the numerator reflects the number of equal parts.

When a fraction is divided, it reciprocated i.e, denominator and numerator change their places. So, in given fraction-

4÷4/6=4×6/4

Step-by-step explanation:

A rise or a decline may be represented by an exponential function in either direction.

This is further explained below.

A)

The exponential function is represented as follows for fuel A:

f(x)=2.96(1.04)^x

A representation of an exponential function looks like this:

y=a b^x

Where b is the rate being calculated.

b=1.04

Since b (which is equivalent to 1.04) is bigger than 1, it follows that the price of gasoline A is going up.

B)

A representation of an exponential function may be seen in the table.

To get the cost of gasoline type B, just divide the current price by the price that was in effect just a moment ago.

Therefore, we have:

[tex]\begin{aligned}&b=\frac{3.41}{3.22} \\&b=1.06\end{aligned}[/tex]

1.06 is a higher number than 1.04, by way of comparison (the rate of fuel A).

Consequently, gasoline B had a bigger percentage shift in price than fuel A did.

Let's use the Bharkara Equation to find the roots:

So we get the roots x = 3 and x = -5. This are the point at which the graph changes its sign.

The quadratic term (the one multiplying x²) is 1, which is positive. Because of that, the parabola of the quadratic expression has a minimum vertex:

For the drawing, it can be seen that when x is between -5 and 3, the equation has a negative sign, while when x is lower than -5 or greater than 3 the expression has positive sign. We want the expression:

So, when it is greater than 0, meaning positive. Then, the set that solves the quadratic inequation is:

The two figures are not the same size because 6/3 twice less than 8/4.

A scale factor is defined as the factor that shows how much a figure is greater or smaller than the original size that it's been compared to.

This can be calculated by dividing the bigger sides by the smaller sides.
