The graph intersects the x-axis at ( 1/2 , 0) .

A cartesian coordinate system, which uses signed distances between two fixed perpendicular oriented lines and the point measured in the same unit of length, uniquely identifies any point in a plane by a pair of numerical coordinates.

We know that at the x-axis the value of y is 0 .

Now substituting the value of y in the equation of the graph we get :

y = - 2x + 1

at y = 0 ,

0 = -2x + 1

or, -1 = -2 x

or, x =  1 / 2

Hence the co-ordinate of the point where the graph passes through x-axis is ( 1/2 , 0 ) .

The sequence of transformations that maps ∆ABC to ∆A′B′C′ is a reflection across the line y = x followed by a translation 10 units right and 4 units up.

A certain order of transformational occurrences is referred to as a transformational sequence. This indicates that more than one transformation is handled by a series of transformations, and the order in which they happen is important.

We are given that ΔA'B'C' exists formed after a sequence of transformations applied to ΔABC.

The first exists a reflection across a line and the second exists a translation.

The coordinates of point C exist (-4, -2). After reflection from the line y = x, the coordinates become (2, -4).

Also, the coordinates of point C' are (12, 0).

So, to get point C' from point C, we should add 10 units to the x-coordinate and 4 units to the y-coordinate.

The translation of 10 units right and 4 units up.

Therefore, the complete transformation is

The more likely event is (B) Enzo passes the test , the correct option is (B).

In the question ,

it is given that

the probability that Felipe will pass the test is 0.19

Converting 0.19 to percent , we get

0.19 = 0.19/100 = 19%

the probability that Enzo will pass the test is 1/4 ,

Converting 1/4 to percent , we get

1/4 = 1/4 * 100 = 100/4 =25%

hence , the probability of Felipe passing the test is 19% and the probability that Enzo passes the test is 25% ,

On comparing we see that 25% > 19% , which means Enzo has higher chance of passing the test than Felipe .

Therefore , the more likely event is (B) Enzo passes the test , the correct option is (B).

For the given quadratic function, we have that:

The x-intercepts of the function are the same as the zeros, that is, the values of x for which f(x) = 0.

For this problem, the function is defined as follows:

f(x) = -2x² - 4x.

Hence the x-intercepts are given as follows:

-2x² - 4x = 0

2x² + 4x = 0

2x(x + 2) = 0.

Hence:

The numeric value at x = -4 is calculated replacing each instance of x by -4, hence:

f(-4) = -2(-4)² - 4(-4) = -16.

We have to solve for x as follows:

-2x² - 4x = 2

2x² + 4x + 2 = 0

x² + 2x + 1 = 0

(x + 1)² = 0.

The rule that describes the composition transformation that maps ABCD to

A''B''C''D'' is the option;

Translation of negative 6 units x, 1 units y composition reflection across the x-axis.

The given coordinates of parallelogram ABCD are (3, 5), (6, 5), (4, 1), (1, 1)

The coordinates of the parallelogram A'B'C'D' are; A'(3, -5), B'(6, -5), C'(4, -1), D(1, -1)

The coordinates of the parallelogram A''B''C''D'' are;

D(-5, 0), C''(-2, 0), A''(-3, -4), B''(0, -4)

The image of the point (x, y), following a reflection about the x-axis is the point (x, -y)

The difference in the coordinates of the parallelogram ABCD and A'B'C'D'

is the change in the sign of the y-coordinates

Therefore, the transformation that gives the parallelogram A'B'C'D' from

the parallelogram ABCD is a reflection about the x-axis

The difference between the coordinates of the vertices of the

parallelogram A'B'C'D' and the parallelogram A''B''C''D'', is a change in the

x-value by (-6), and a change in the y-value by (+1)

Therefore, the parallelogram A''B''C''D'' can be obtained from parallelogram

A'B'C'D', by a translation of -6 units (left) in the x-direction and a translation

of 1 unit, x in the y-direction

The solution to the linear-quadratic system of equations are: [tex]\begin{pmatrix}x=1,\:&y=3\\ x=-5,\:&y=-3\end{pmatrix}[/tex].

The Standard form for a quadratic equation is  ax²+ bx + c=0, where: a, b and c are your respective coefficients. In the quadratic function, the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

To solve a quadratic function, you should find the discriminant: D=b²-4ac and then use this variable in the formula: [tex]x=\frac{-b\±\sqrt{\Delta} }{2a}[/tex].

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=4x+3. Where:

m= the slope. It can be calculated for Δy/Δx .

b= the constant term that represents the y-intercept.

The question asks the solution of the system the following equations

y=x²+5x-3 (1)

y=2+x      (2)

Firstly, you should subtract equation 1 and 2, as result, you have

y-y= x²+5x-3 -(2+x)

y-y= x²+5x-3 -2 -x

0= x² +4x -5

After that for finding x, you should  solve the equation  x² +4x -5=0. Then,

D=b²-4ac

D= 4²-4*1*(-5)

D=16+20

d=36

Thus,

[tex]x=\frac{-b\±\sqrt{\Delta} }{2a}= \frac{-4\±\sqrt{36} }{2*1}= \frac{-4\±\ 6 }{2}[/tex]. Therefore

x1=(-4-6)/2= -10/2=-5

x2= (-4+6)/2 = 2/2=1

7 1/5 divided by 8 in fraction form is 36 / 40 = 9/ 10 and in decimal form = 0.9

A fraction is a numerical expression expressing a portion of the whole. There are two parts: a numerator and a denominator. The denominator is the total number of pieces that make up the whole, while the numerator is the number of equally sized portions of the whole. For instance, in the percentage of 3/8 has a denominator of 8 and a numerator of 3.

We have been given that -

7 1/5 divided by 8

Rewrite as

(36/5) / 8

36 / 5×8

Multiplying 5 with 8 and we get

36 / 40

Follow these steps to convert an incorrect fraction to a mixed number: Subtract the denominator from the numerator. The quotient's whole number component should be written down. Write the leftover amount on top of the original denominator.

36/ 40 in decimal form = 0.9

0.9 = 0.9 × 10 /1 × 10

= 9 / 10

Hence, When 7 1/5 is divided by 8, the result is 36/40 (9/10) and 0.9 (in decimal notation).

Using a linear function, it is found that:

b. He can ride at most 15 miles without going over the limit.

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which the coefficients are described as follows:

For the context of this problem, the slope and the intercept are defined as follows:

Hence the cost function, considering x miles, is given as follows:

C(x) = 0.45x + 5.

He wanted to spend $12 or less on a beach bike rental, hence the inequality that models this situation is given by:

C(x) ≤ 12.

5 + 0.45x ≤ 12.

The inequality is solved similarly to an equality, isolating the variable and finding the range of values, hence the solution is found as follows:

0.45x ≤ 7

x ≤ 7/0.45

What is Pythagoras theorem ?

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The Pythagoras theorem's equation is as follows:

H² = P² + B²

The triangle's third side will be the following length:

Let x represent the triangle's third side's length.
