The number of packs of markers that Mr. Sowers can purchase is 6.

The maximum amount that Mr. Sowers can spend is $35. This means that the amount can either by $35 or less than $35. Thus, the inequality sign that would be used is the less than or equal to sign, ≤ .

total amount spent on the packet of markets ≤  budget

(cost of one packet x number of packets) ≤ $35

$5.49x ≤ $35

In order to determine the value of x, divide both sides of the equation by 5.49

x ≤ $35 / 5. 49

x ≤ 6.38

x ≤ 6

1. The biggest size of each brick that Hannah can be able to use is 32.

2. The value of x when there are now x cans stacked on a shelf that hold 36 cans when full is 22 cans.

From the information, Hannah needs to build two wall, one has a height of 1024 feet and the other of 672 feet and she has to use bricks of equal sizes for both wall. It should be noted that this implies that we've to calculate the highest common factor for 672 and 1024. This is 32.

2. The value of x will be:

= (36/2) + 4

= 18 + 4

= 22

Therefore, x is 22. This means that there are 22 cans.

Step-by-step explanation:

that only means we need to put the given values into every place, where the variable is used in the expression.

this is straight forward.

x² for x = -9 means

(-9)² = 81

you remember, a² = a×a.

and when a is negative, this is then the multiplication of a negative number with a negative number, and that result is positive.

so, a square operation always delivers a positive result for real numbers as input, no matter if the input was already positive or negative.

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).

The composition transformation that maps ABCD to A''B''C''D'' comprises

of two or more transformations that maps the image

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

The rate of change (m) = 9

The starting number (b) = 100

The equation is: y = 9x + 100

(0, 100) is the ordered pair for the starting number.

See the image for the graph of y = 9x + 100.

To create the equation of a line, we need to determine the following:

Y-intercept/starting value = b

Slope of the line/rate of change = m

The ordered pair of the y-intercept or starting value is represented as (0, b), where b is the value of y on the y-axis where the line intercepts the y-axis and x = 0 at this point.

These values can be substituted into y = mx + b, which represents the equation of the line in slope-intercept form.

From the information given, we have:

Y-intercept/starting value (b) = 100

Slope of the line/rate of change (m) = 9

To write the equation of the line, substitute m = 9 and b = 100 into y = mx + b:

y = 9x + 100

The ordered pair for the starting number would be: (0, 100).

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).

Pythagoras theorem - The length of the third side is 6.71unit

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.

9² = 6² + x²

81 = 36 + x²

x² = 45

x = 6.708

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 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
