Answer:

what kind of math is that?

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:

Step 1. Twice the difference of a number and 2

Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

[tex]2(n-2)[/tex]

Step 2. Twice the difference of a number and 2 is at most -27

[tex]2(n-2)\leq -27[/tex]

_________________________________________

So the mathematical form of the statement twice the difference of a number and 2 is at most -27 is:

[tex]\boxed{2(n-2)\leq -27}[/tex]

The right answer is Option B: 9/26

Step-by-step explanation:

Given equations are;

[tex]2x+\frac{4}{3}y=1[/tex]     Eqn 1

[tex]y-\frac{9}{13}x=9[/tex]     Eqn 2

For eliminating x, we will make the variables equal with opposite signs.

In Eqn 1;

We will multiply Eqn 1 by 9/26 to get +9/13x.

[tex]\frac{9}{26}(2x+\frac{4}{3}y=1)\\\\\frac{9}{13}x+\frac{6}{13}y=\frac{9}{26}[/tex]

Therefore;

We will multiply Eqn 1 by 9/26.

The right answer is Option B: 9/26

minimum value of the quadratic function f(x) = x² - 2x + 7 is at x=1 & is (1, 6).

Step-by-step explanation:

Here we have ,  f(x) = x² - 2x + 7 or [tex]f(x) = x^2 - 2x + 7[/tex] . We need to find the minimum value of f(x) for which we need to differentiate it one time and equate it to zero . Value of x at which first differentiation of f(x) is zero will be the minimum value of function  . Let's solve this:

[tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]\frac{df(x)}{dx} = \frac{d(x^2 - 2x + 7)}{dx}[/tex]

⇒ [tex]\frac{df(x)}{dx} = \frac{d(x^2)}{dx} - \frac{d(2x)}{dx} + \frac{d(7)}{dx}[/tex]

⇒ [tex]\frac{df(x)}{dx} = 2x-2 = 0[/tex]

⇒ [tex]2x-2 = 0[/tex]

⇒ [tex]x =1[/tex]

Now, value of function at x=1 is :

[tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(x) = x^2 - 2x + 7[/tex]

⇒ [tex]f(1) = 1^2 - 2(1) + 7[/tex]

⇒ [tex]f(1) = 8- 2[/tex]

⇒ [tex]f(1) = 6[/tex]

Therefore, minimum value of the quadratic function f(x) = x² - 2x + 7 is at x=1 & is (1, 6).

The minimum value of the quadratic function f(x) = x² - 2x + 7 is 6, which occurs at x = 1, as determined by finding the vertex of the parabola.

The minimum value of the quadratic function f(x) = x² - 2x + 7 can be determined by finding the vertex of the parabola represented by the function. This is because the graph of a quadratic function is a parabola, and if the coefficient of the x² term is positive, the parabola opens upwards and the vertex represents the minimum point.

To find the vertex, use the formula -b/2a to determine the x-coordinate of the vertex. For the function f(x), the value of 'a' is 1 and 'b' is -2. Substituting these values gives us the x-coordinate of the vertex as x = -(-2)/(2*1) = 1. Substituting x = 1 back into the function f(x), we get the y-coordinate of the vertex, which is the minimum value of the function: f(1) = (1)² - 2*(1) + 7 = 6.

Therefore, the minimum value of the quadratic function f(x) is 6, occurring at x = 1.

Answer:

490

Step-by-step explanation:

oh lord here we go again

get the area of all signs again

5 x 5 = 25

theres 2 of those squares so make that 50

8 x 5 = 40

theres 4 of those sides so 40 x 4 = 160

10 x 10 = 100

theres two of those so its 200

2 x 10 = 20

4 of these so 80

add all the final ones

50 + 160 + 200 + 80 = 490

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

[tex]\text{Amount of money saved}=8\times 100=\$800[/tex]

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

[tex]I=\frac{48}{8}=\$6[/tex]

So, in conclusion Harry did earn $6 in interest for every $100

Answer:

Equation for total number of balls = 8x+6x+5x =19x where x represent a single tennis ball.

Step-by-step explanation:

Given that Kayla has;

8 red tennis balls

6 green tennis balls

5 blue tennis balls

Let;

red tennis ball be r

green tennis balls be g

blue tennis balls be b

The total number of tennis balls is 8+5+6=19 balls

Multiplication is a repeated form of addition where ;

5*5*5 = 3*5= 5+5+5= 15

In this case, r+g+b=19 but r ,g and b are not repeated thus applying multiplication equation will not give the sum of the balls

However if you let a single ball to be represented by x then a single ball x will be multiplied by the number of balls in that category to get the total number of balls per color

For red balls= 8x

For green balls=6x

For blue balls=5x.

Total number of balls = 8x+6x+5x =19x where x represent a single tennis ball.

To find the total number of tennis balls Kayla has, she needs to add the number of each color of balls together, not multiply. When she adds 8 red, 6 green, and 5 blue balls, she gets 19 tennis balls in total.

In this case, Kayla doesn't need to use a multiplication equation to find out the total number of tennis balls she has. Rather, she just needs to add the numbers together. Kayla has 8 red tennis balls, 6 green tennis balls, and 5 blue tennis balls. So, to figure out how many tennis balls she has in total, she simply adds these numbers together: 8 + 6 + 5 = 19 tennis balls in total.

To prove ABCD is a rhombus, showing that all sides of parallelogram ABCD are equal in length would suffice.

If ABCD is a parallelogram, to prove that it is a rhombus, a statement that would suffice is that all four sides of the parallelogram are of equal length.

This is because a rhombus is defined as a parallelogram with four congruent sides. If any one of its diagonals bisects an angle of the parallelogram, or its diagonals are perpendicular, or its diagonals are of the same length, these conditions would not exclusively prove it to be a rhombus, although they are properties of a rhombus. However, the definition of a rhombus centers on the equality of all sides.

Equal adjacent angles would not necessarily mean that all sides are equal, which is a requirement for a rhombus.

The correct option is (B).

To prove that a parallelogram is a rhombus, you need to show that all four sides are of equal length. A parallelogram has opposite sides that are equal and parallel, but for it to be a rhombus, every side must be equal in length to every other side.

The statement options you might have in your image could be something like:

a. Diagonals are perpendicular (AC ⊥ BD)

b. Adjacent angles are equal (∠ABC ≅ ∠CDA)

c. One pair of opposite sides are equal (AB ≅ CD)

d. Diagonals are equal (AC ≅ BD)

From these options:

- Option a: If the diagonals are perpendicular, it's an indication that the parallelogram could be a rhombus, but it's not conclusive proof because a rectangle also has perpendicular diagonals.

- Option b: Equal adjacent angles would not necessarily mean that all sides are equal, which is a requirement for a rhombus.

- Option c: Having one pair of opposite sides that are equal is already a property of a parallelogram and does not prove it's a rhombus.

- Option d: Equal diagonals would be a property of a rectangle, not necessarily a rhombus.

The conclusive proof that a parallelogram is a rhombus would be if you can show that all sides are of equal length (not provided in the typical options above), or if the diagonals are perpendicular and bisect each other into equal segments. This latter property is unique to a rhombus among parallelograms. If this were one of the choices, it would be the correct answer.

Since I can't see the options, please review them and look for the one that indicates all four sides are of equal length or that the diagonals bisect each other into equal segments and are perpendicular. That would be the correct choice to prove the parallelogram is a rhombus.

Answer:

Step-by-step explanation:

Answer:

y = 9

Step-by-step explanation:

Calculate the slope m of line k using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, 8) and (x₂, y₂ ) = (2, y)

m = [tex]\frac{y-8}{2-5}[/tex] = [tex]\frac{y-8}{-3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]

The slope of line l is m = 3, thus slope of line k is

m = - [tex]\frac{1}{3}[/tex]

Equating the 2 slopes for line k

[tex]\frac{y-8}{-3}[/tex] = - [tex]\frac{1}{3}[/tex] ( multiply both sides by - 3 )

y - 8 = 1 ( add 8 to both sides )

y = 9

To find the value of y, we can use the fact that the slopes of Perpendicular lines are negative reciprocals of each other. Using the given information and equations, we can solve for y.

To determine the value of y, we can use the fact that the slopes of perpendicular lines are negative reciprocals of each other. Since line l has a slope of 3, the slope of line k would be -1/3. We can use the slope-intercept form, y = mx + b, to find the equation of line k.

Substituting the coordinates (5, 8) and the slope -1/3 into the equation, we can solve for y.

Using the point-slope form, y - y1 = m(x - x1), where (x1, y1) is the given point (2, y). We can rearrange this equation to get y = mx + b form, substitute the values, and solve for y to find the value of y.
