Answer:

x = 1, y = 3

Step-by-step explanation:

Given:

x - y = -2

2x + y = 5

First, add y on both sides for the first equation.

x = y - 2

Then, plug in x into the second equation.

2(y -2) + y = 5

2y - 4 + y = 5

3y = 9

y = 3.

Next, now that you've found y, plug it into either the first or second equation to solve for x. I'll be using the second equation.

2x + 3 = 5

2x = 2

x = 1.

Ans: x = 1, y = 3

Answer:

AGIB

Step-by-step explanation:

I solved it eh.

Pretty simple honestly.

But school ends!

Each side and each area were calculated using the Pythagoras theorem.

The Pythagoras theorem states that, in a right triangle, the sum of squares of shorter sides is equal to the square of the hypotenuse.

So, using the Pythagoras theorem

[tex]TU^2=175^2-79^2[/tex]

[tex]TU^2=24384[/tex]

[tex]TU=156.15[/tex]

So, the corresponding area of the rectangle = 156.15*79 =12335.85 square units.

Similarly, [tex]GH = \sqrt{207^{2}-98^2 }[/tex]

[tex]GH=182.33[/tex]

So, the corresponding area of the triangle = 0.5*182.33*98 = 8934.27 square units.

Thus, each side and each area were calculated using the Pythagoras theorem.

By satisfying all the four criteria, the quadrilateral with the vertices A(x, y) = (-5, 0), B(x, y) = (5, 0), C(x, y) = (-3, 4) and D(x, y) = (3, 4) is an isosceles trapezoid.

Based on vectorial expressions, an isosceles trapezoid satisfies the following properties:

(i) [tex]\overrightarrow{CD} = k \cdot \overrightarrow{AB}[/tex], for k ∈ [tex]\mathbb{R}[/tex]    

(ii) AB ≠ CD    

(iii) [tex]\overrightarrow{AC} \neq \overrightarrow {BD}[/tex]  

(iv) AC = BD

Now we proceed to prove each property:

Requisite I

(3 - (-3), 4 - 4) = (6, 0)

(5 - (-5), 0 - 0) = (10, 0)

(6, 0) = (5/3) · (10, 0)

Requisite II

AB = 6, CD = 10

AB ≠ CD

Requisite III

[tex]\overrightarrow{AC} = (2, 4)[/tex]

[tex]\overrightarrow{BD} = (-2, 4)[/tex]

[tex]\overrightarrow{AC} \neq \overrightarrow {BD}[/tex]

Requisite IV

[tex]AC = \sqrt{[-3-(-5)]^{2}+(4-0)^{2}}[/tex]

[tex]AC = \sqrt{2^{2}+4^{2}}[/tex]

[tex]AC = 2\sqrt{5}[/tex]

[tex]BD = \sqrt{(3-5)^{2}+(4-0)^{2}}[/tex]

[tex]BD = \sqrt{(-2)^{2}+4^{2}}[/tex]

[tex]BD = 2\sqrt{5}[/tex]

AC = BD

The figure with the entire quadrilateral is shown below. Therefore, the quadrilateral with the vertices A(x, y) = (-5, 0), B(x, y) = (5, 0), C(x, y) = (-3, 4) and D(x, y) = (3, 4) is an isosceles trapezoid.

Answer:

C and D

Step-by-step explanation:

Both have a 2/3 chance of success, and are completed 7 times :)

let me know if you need more explanation

Options (C) and (D) are same as Diego predictions.

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

Diego predicts that his basketball team has two third probability of winning each of their next seven games.

The probability of winning = [tex]\frac{2}{3}[/tex]

We need to choose from the option, which has the same probability as above.

Option A:

Put the number 0 through 7 in a bag pick a number from the back.

Here, the probability = [tex]\frac{1}{8}[/tex] and the process is done for one time only.

So, this option is not same as above.

Option B:

Will a standard number cube 7 times count the number of twos.

Here, the probability = [tex]\frac{1}{6}[/tex]

So, the option is not same as above.

Option C:

Roll a standard number cube 7 times count how many of ones to threes and fours.

Here, the probability = [tex]\frac{4}{6}[/tex]

⇒ [tex]\frac{2}{3}[/tex]

So the option is same as above.

Option D:

Marcus spinner with 12 equally sized sections right when on four of the sections spin the spinner seven times and count the number of times it ends on the win.

Here, the probability = [tex]\frac{8}{12}[/tex]

⇒ [tex]\frac{2}{3}[/tex]

So the option is same as above.

Option E:

Put 10 white chips and fiber chips in a bag draw a chip from the bag record its results and put it back in the bag do the seven times and count the total number of white chips drawn.

Here, number of fiber chips is not given.

So, we could not predict the probability for this option.

Hence we can conclude that options (C) and (D) are same as Diego predictions.

Step-by-step explanation:

An equation is formed of two equal expressions. The graph can be used to solve the equation 2x-1=x+2 is the Top right one.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The two of the given equations can be written as,

y = 2ˣ - 1

y = x + 2

If the two equations are now when plotted on the graph, it will be like the one shown below. Hence, the graph can be used to solve the equation 2x-1=x+2 is the Top right one.

Answer:

y = 8x + 25

Step-by-step explanation:

Using the coordinates (10, 105) and (20, 185)

The standard linear equation is expressed as y = mx+c

m is the slope

c is the intercept

m = 185 - 105/20-10

m = 80/10

m = 8

Get the y-intercept

Since y = mx+c

105 = 8(10) + c

105 = 80 + c

c = 105 - 80

c = 25

Get the required equation

Recall that y = mx+c

y = 8x + 25

Hence the required equation is y = 8x + 25

Answer:

G = (-5,-5)

Step-by-step explanation:

d = sqrt (x^2 - x^1)^2 + (y^2 - y^1)^2

Let's use the coordinate pairs: (6,4) and (6,-5).

Input.

d = sqrt (6 - 6)^2 + (-5 - 4)^2

Solve.

d = sqrt 0 + (-9)^2

d = sqrt 0 + 81

d = sqrt 81

d = 9

Count 9 places back from (6, -5) , then you will arrive at (-5,-5).

Thus, the fourth vertex of the rectangle "EFGH" is (-5,-5) for G.
