Answer:

First choice: 08:25

Step-by-step explanation:

Squared Clock is 5 minutes slower than the round clock
since the round clock is 10 minutes behind actual time, square clod is 15 minutes behind actual time

Time on square clock = 8:05
So actual time = 8:05 + 15 = 8:20

Rectangular clock is 5 minutes ahead of actual time
So time on rectangular clock is 8:20 + 05 = 8:25

Answer: First choice: 08:25

Let:

y=2x+18 (1)

4x+5y=20 (2)

replace (1) into (2)

4x+5(2x+18)=20

Using distributive property:

4x+10x+90=20

Add like terms:

(4x+10x)+90=20

14x+90=20

subtract 90 from both sides:

14x+90-90=20-90

14x=-70

Divide both sides by 14:

14x/14=-70/14

x=-5

Finally, replace the value of x into (1)

y=2(-5)+18

y=-10+18

y=8

Let:

2x+2y=6 (1)

3x-5y=25 (2)

From (1) let's solve for x:

subtract 2y from both sides:

2x+2y-2y=6-2y

2x=6-2y

Divide both sides by 2:

x=(6-2y)/2

x=3-y (3)

Replace (3) into (2)

3(3-y)-5y=25

Using distributive property:

9-3y-5y=25

Add like terms:

9+(-3y-5y)=25

9-8y=25

subtract 9 from both sides:

9-8y-9=25-9

-8y=16

Divide both sides by -8:

(-8y)/(-8)=(16)/(-8)

y=-2

Finally, replace the value of y into (3)

x=3-(-2)

x=3+2

x=5

f(x-1) + 2 translates f(x) 1 unit to the right and 2 units up. Then, the graph of the new function is:

f(x) = x^2

To translate the function 2 units down (along the y axis) subtract 2

F(x) = x^2 -2

To translate the function 3 units to the right (along the x-axis) subtract 3 units inside the parentheses.

f(x) = (x-3)^2 - 2

In order to graph the functiom we need to identify the parent function and the vertical and horizontal shifts that might be done to the function.

In this case we see that the parent function is a cubic function since the greater degree is 3

this means that f(x) is a transformation of g(x)

then

the horizontal shifts since there is sum inside the parentheses the shift will be 1 unit to the left.

the vertical shift will be 1 unit up since there is a sum outside the parentheses.

and finally since there is a - it means that the function is reflected over the x-axis

the parent function will be the red line and the function #15 is the blue line.

In order to find points we can tabulate the values for given xs' and construct the graph.

Start by making a table like this:

now since the function is given we can replace x with the values and find y

then after tabulating values should look like this

Now looking at the graph on the blue function we can see that the function is decreasing until reaching x=-1, however after that the function will continue to decrease but at a different rate, which means that over the interval

the function will be decreasing

cosecant = hypotenuse / opposite side

Angle = 7pi/4

Answer:

5 cups of flour.

Step-by-step explanation:

I know the wording of the problem may be confusing at first, but if you look at it a little bit, it's just multiplication and division.

To start,

12 biscuits require 2 cups of flour,

meaning that 6 biscuits (half of the original) only require 1 cup.

(12/2 = 6)

Next,

We need to find how much flour is in 30 biscuits.

We know that 1 cup is in 6 biscuits, and if you were to find how much was in 30 biscuits, you would just need to divide 30 by 6.

(30/6 = 5)

5 cups of flour would be your answer.

To put it mathematically,

(12/2 = 6), (30/6 = 5)

Answer:

11

Step-by-step explanation:

The answer would be 11, because when you add 5 and 6 together, you get 11. Pretend you had 5 cookies, and you got 6 more.

5 Cookies- O,O,O,O,O

6 More Cookies- O,O,O,O,O,O

If you add the cookies up, you get 11.

To round to the nearest tenth, we must round it to the nearest hundredth first, we have

B. The probability of randomly select the correct access code on the first try:

C. The probability of not selecting the correct access code on the first try :

Answer:

3, 8

Step-by-step explanation:

Let's make the first integer x and the second integer y.

Now, you take the information given and convert it into a system of equations:

xy = 24

x = 5y - 7

y = 24 / x

Now, we substitute:

(5y - 7) · y = 24

Distribute y

5y² - 7y = 24

Rearrange it into a quadratic equation:

ax² + bx + c = 0

5y² - y - 24 = 0

Use the quadratic formula (shown in image) and plug in the values:

x = (- (7) ± [tex]\sqrt{(-7^})^{2} -4(5)(-24)}[/tex] ) / 2(5)

[tex]\sqrt{(-7)^{2} -4(5)(-24)}[/tex] = [tex]\sqrt{49 - (-480)} = \sqrt{529} = 23[/tex]

Remember that ± means there are two y values

[tex]x = \frac{7+23}{10} = \frac{30}{10} = 3[/tex]

and

[tex]x = \frac{7-23}{10} = \frac{-16}{10} = -1.6[/tex]

Since y must be an integer, we know that y = 3

Now, plug in y:

5(3) - y = 24

15 - y = 24

- y = -24

y = 8

Let's check to see if we are right:

5y - 7 = 5(3) - 7 = 15 - 7 = 8

It works!

We are asked to find the value of b that makes quadrilateral RSTU a parallelogram.​

We know from the properties of a parallelogram that the opposite angles are always equal.

Let us equate the angles and solve the equation for b.

Similarly,

Given the line shown in the figure passes through the points (-3, -4) and (1, 2)

We will write the equation of the line.

First, we will find the slope of the line using the following formula:

Substitute with the given points:

The equation of the line in point-slope form will be as follows:

Convert tot he slope-intercept form, so, the equation will be:

Now, we will check the options to see the correct equations.

So, the answer will be, we will select the options:

A. y+4 = 1.5 (x+3)

B. y = 1.5x + 0.5

C. y - 2 = 1.5 (x - 1)

For 9 of games is the cost of these plans the same.

Moving the variables to one side of the equation and the numeric portion to the other allows us to solve a linear equation with one variable. As an illustration, the equation x - 1 = 5 - 2x can be resolved by transferring the numerical components to the right side of the equation while leaving the variables on the left. Therefore, we receive x + 2x = 5 + 1. Thus, 3x Equals 6. As a result, x = 2. The formula for a two-variable linear equation is Ax + By + C = 0, where A and B are the coefficients, C is a constant term, and x and y are the two independent variables, each with a degree of 1. A linear equation involving two variables, for illustration, is 7x + 9y + 4 = 0.

Consequently, you would multiply $9.45 and $4.45 by the same number (I selected 9 because there are only one or two possible answers), then add $85 to the result for the $4.45 amount.

9.45 x 9

= 85.05

4.45 x 9

= 40.05 +85

= 125.05

The three transformations—rotations, reflections, and translations—can be combined to produce congruent shapes. The truth is that any pair of congruent shapes can be matched to one another by combining one or more of these three transformations.

Explain transformations.

A point, line, or geometric figure has four different transformations that can be applied to alter its appearance. While the term "Image" refers to the position and final shape of the object, "Pre-Image" refers to the object's shape before transformation.

Given Information

The size and shape of the figures are preserved during stiff transformations, as we already know (reflections, translations, and rotations). Always in harmony with one another is the pre-image.

These transformational skills are all possessed by Matt:

Reflection

The reason a reflection maintains its original form Comparable locations between the pre-image and the picture remain apart from the line of reflection.

Rotations as a Transformation of Congruence

When a figure rotates, it twists. Despite being the same size and shape, the figurine appears to have toppled over. A clock is an excellent example of how the globe rotates in reality. Every hour or every day, the connecting arms of a clock revolve around its axis. The degree of a rotation determines what kind of rotation it is; popular rotations include 90, 180, and 270 degrees. Before spinning around completely and going back to where it started, the figure rotates 360 degrees. the clockwise or counterclockwise direction in which a rotation is made. This data can be used to determine the degree, amount, a revolution's speed and direction.

Congruence translational transformation

When an object or shape is transferred from one location to another without altering its size, shape, or orientation, we refer to the transfer as a movement. A translation, often known as a slide, involves moving every point on an object or shape uniformly and in one direction.
