Answer:

x = [tex]\frac{5}{7}[/tex] , y = - [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

Given 2 equal matrices then the corresponding elements in each matrix are equal, then

2x + y = 1 → (1)

x - 3y = 2 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate y

6x + 3y = 3 → (3)

Add (2) and (3) term by term to eliminate y

7x + 0 = 5

7x = 5 ( divide both sides by 7 )

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

Substitute this value into (1) and evaluate for y

[tex]\frac{10}{7}[/tex] + y = 1 ( subtract [tex]\frac{10}{7}[/tex] from both sides )

y = [tex]\frac{7}{7}[/tex] - [tex]\frac{10}{7}[/tex] = - [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

We cannot but partial balls so we need  whole number of balls.

we can use units to easily visualze the issue.

56 $/ball and we have $198.98. We need balls so we do

198.98 / 56 = 3.55

We can at most buy 3  balls.

EXTRA: 56 * 3 = 168

will have 30.98 leftover

Answer:

The answer is 6

Answer:

d = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₉ = 16 , then

- 12 + 8d = 16 ( add 12 to both sides )

8d = 28 ( divide both sides by 8 )

d = [tex]\frac{28}{8}[/tex] = [tex]\frac{7}{2}[/tex]

Answer:

If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.

SEE THE IMAGE FOR SOLUTION

The coordinates of endpoint V is (7, -27) if one endpoint is U(3,5) and the midpoint of UV is (5, -11)

Midpoint of a line is a point that divides any line into two equal parts.

The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as:

[tex]M(X, Y)= (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )[/tex]

Given the following

midpoint of UV = (5, -11)

U = (3, 5)

Get the other coordinate x2 and y2

Based on the formula above:

[tex]X = \frac{x_1+x_2}{2}\\5=\frac{3+x_2}{2}\\10 = 3 + x_2\\x_2 = 10-3\\x_2 = 7[/tex]

Get the other coordinate x2

[tex]Y = \frac{y_1+y_2}{2}\\-11=\frac{5+y_2}{2}\\-22 = 5 + y_2\\y_2 = -22-5\\y_2 = -27[/tex]

This shows that the coordinates of endpoint V is (7, -27)

Answer:

g= -4

Step-by-step explanation:

1. Remove the parentheses by multiplying 5 by 10 and 9 by 2 so that would be 10g + 50= 2g + 18

2. Move the terms by their correct side. Constants to the right and variables to the left so that would be 10g - 2g = 18 - 50

3. Now do 10 - 2 and 18 - 50 so the results will be 8g = -32

4. Divide both sides of the equation by 8 so 32÷8.

5. The result is g= -4

Answer:

g = - 4

Step-by-step explanation:

Given

10(g + 5) = 2(g + 9) ← divide both sides by 2 )

5(g + 5) = g + 9 , that is

5g + 25 = g + 9 ( subtract g from both sides )

4g + 25 = 9 ( subtract 25 from both sides )

4g = - 16 ( divide both sides by 4 )

g = - 4

Answer: 8 units

Step-by-step explanation:

To find the distance between 2 points, we want to use the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given the 2 points, all we have to do is plug them in.

[tex]d=\sqrt{(7-(-1))^2+(8-8)^2}[/tex]      [parenthesis]

[tex]d=\sqrt{(8)^2+(0)^2}[/tex]                        [exponent]

[tex]d=\sqrt{64+0}[/tex]                               [add]

[tex]d=\sqrt{64}[/tex]                                     [square root]

[tex]d=8[/tex]

Now, we know the distance is 8 units.

Answer:

7 quaters and 19 dimes

Step-by-step explanation:

Let say x the numbers of quaters,

2*x+5 the numbers of dimes

In cents,: 25*x+10*(2x+5)=365

25x+20x+50=365

45x=365-50

45x=315

x=7

Number of quaters: 7

Number of dimes: 2*7+5=19

Proof:

7*25+10*19=365

Using it's concept for the difference between points, the absolute value inequality |x - y| < 10 represents when Erik wins the game, and the inequality |x - y| ≥ 10 represents when Nina wins the game.

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers to greater than 10, then Nita wins. Use what you know about inequalities and absolute values to better understand the game.

The absolute function is defined by:

It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.

For this problem, we have that:

The difference between these two numbers is:

|x - y|.

Erik wins if the difference is less than 10, hence:

|x - y| < 10.

Hence:

Using it's concept for the difference between points, the absolute value inequality |x - y| < 10 represents when Erik wins the game, and the inequality |x - y| ≥ 10 represents when Nina wins the game.
