Solve for x in the diagram below.

Answer:

Step-by-step explanation:

Cost of two tubes = $ 3.23

Regular price of one tube = $ 1.79

so, the cost of other tube = 3.23 - 1.79 = $ 1.44

Discount = 1.79 - 1.44 = $ 0.35

Answer:

The distributive property is to multiply the outside of a parenthesis by each term inside, for example:

[tex]x(y+z)=xy+xz[/tex]

this cannot be done with the trigonometric functions such as the sine.

An example of this:

let's prove that we don't get the correct result using the distributive property in the following expression:

[tex]sin (\pi+\pi/2)[/tex] ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]

We add the elements in the parentheses on the left side:

[tex]sin(3\pi/2)[/tex]  ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]

this are known values of the sine function:

[tex]sin(3\pi/2)=-1[/tex]

[tex]sin(\pi)=0[/tex]

[tex]sin(\pi/2)=1[/tex]

substituting these values we will get that:

-1  ≠ 0 +1

-1  ≠ 1

Thus we notice that we don't get the correct result using the distributive property.

The correct way to express the angle sum in the sine function is:

[tex]sin(a+b)=sin(a)cos(b)+sin(b)cos(a)[/tex]

As a is the inscribed angle, the answer is 100/2 = 50

Answer:

(n-2)(n+2)

Step-by-step explanation:

The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.

 (n^2 -4) = (n -2)(n +2)

Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...

 (n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2

This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).

If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).

Answer:

Rachel can make 3/6 out of 4/6 of the recipe.

Step-by-step explanation:

The amount of the recipe that Rachel can make is 1/2.

To determine how much of the recipe Rachel can make with 1/2 cup of yogurt, we need to find the fraction of the recipe that corresponds to that amount.

The recipe calls for 2/3 of a cup of yogurt, and Rachel has 1/2 cup. To compare these two amounts, we need to find a common denominator.

The least common denominator (LCD) for 3 and 2 is 6. To convert the fractions to have a denominator of 6, we multiply the numerator and denominator of 2/3 by 2, and the numerator and denominator of 1/2 by 3:

2/3 x 2/2 = 4/6

1/2 x 3/3 = 3/6

Now, we can see that Rachel has 3/6 cup of yogurt, which is equivalent to 1/2 cup. This means she has exactly half of the required amount.

Therefore, Rachel can make 1/2 of the recipe with the amount of yogurt she has.

Answer:

C) Dilation

Step-by-step explanation:

Rotation is simply rotating an object, therefore, the size and shape remain the same.

Translation is moving the object across the plane, and again, the size and shape will stay the same.

Reflection is reflecting a shape across a certain line. It will still keep its size and shape.

However, dilation is enlarging or shrinking a shape. This means that the shape will change size, but not shape. A dilation of a shape will be similar, but not congruent, to it.

Step-by-step explanation:

To know which numbers are solutions to the inequality, we will follow the steps below:

-3x -3 < 6

add 3 to both-side of the inequality

-3x -3 + 3 <6+3

-3x < 9

Divide both-side of the inequality by -3

-3x/-3 >9/-3

whenever we are dividing both-side of inequality by a negative number, the inequality sign will change

x > -3

all values of x that are greater than -3 will satisfy the inequality

They are 0, 2 and 4

check the solution:

for x=0

-3x -3 < 6

-3(0) -3 < 6

-3 < 6

for x = 2

-3x -3 < 6

-3(2) -3 < 6

 -6 -3 < 6

   -9< 6

for x = 4

-3x -3 < 6

-3(4)-3 < 6

-12-3 < 6

-15 < 6

Answer:

tanΘ = - [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

Given

cosΘ = [tex]\frac{7}{25}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]

The right triangle has sides 7, 24, 25 ← Pythagorean triplet

with adjacent = 7 and opposite = 24

Since position is in fourth quadrant then tanΘ < 0 , thus

tanΘ = - [tex]\frac{24}{7}[/tex]

Answer:

8 hairy dogs

Step-by-step explanation:

There are 15 dogs that are hairy or small

2 that are hairy and small

9 that are small

small - ( hairy and small) =just small

9 -2 = 7 small only dogs

Take the total dogs minus the small dogs minus the small and hairy dogs to find the hairy dogs

15 - 7 - 2 =6

There are 6 hairy dogs

2 small and hairy dogs

7 small dogs

total 15 dogs

If we want the total of the hairy dogs

2 small and hairy + 6 hairy = 8 hairy dogs

Answer:

Say the first car speed as r

Second car speed will be r-14

Since rate times time equal distance, we have

r + (r -14)2 = 300

2r -14 = 300/2

2r = 150+14

r = 164/2 = 82

Speed of slower car 82-14 = 68 km/hr

Answer:

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Step-by-step explanation:

This function is linear, which means that it increases at a steady rate and has the following form:

[tex]y(x) = a*x + b[/tex]

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Answer:

The adjusted balance is generally the most advantageous billing method for the cardholder since the financial charges are lower ($39.20 < $40.07). This happens because interest is only charged on the final monthly balance, and cardholders can decrease that balance during any day of the billing cycle.

Step-by-step explanation:

November 1: balance $2,835.63

November 12: $230 payment

November 12: $121.36 purchase

November 25: $25 payment

annual interest 17.65%

average daily  balance = {(11 x $2,835.63) + [13 x ($2,835.63 - $230 + $121.36)] +  [6 x ($2,835.63 - $230 + $121.36 - $25)]} 31 days = ($31,191.93 + $35,450.87 + $16,211.94) / 30 days = $82,854.74 / 30 days = $2,761.82

financial charge = ($2,761.82 x 30 x 17.65%) / 365 = $40.065 ≈ $40.07

adjusted balance = $2,835.63 - $230 + $121.36 - $25 = $2,701.99

financial charge = $2,701.99 x 17.65% x 30/365 = $39.197 ≈ $39.20

Answer:

The correct answer is y = -3x + 1.

Step-by-step Explanation:

First, you need to use the point slope formula to determine the slope. This is determined by the formula of the second y-coordinate (the y-coordinate in the second ordered pair) minus the first y-coordinate (the y-coordinate in the first ordered pair).

When subtracting the two values, you receive 7 - -5. You would use the KCC (keep, change, change) rule and keep positive 7, change the minus to addition, and turn negative 5 into positive 5. This gives you a value of 12.

Then, you use the same formula layout for the x-coordinates. Take the x-coordinate in the second ordered pair and subtract the x-coordinate in the first ordered pair to get -2 - 2 = -4.

Finally, to determine the slope, divide 12 and -4 to get -3.

Then, to get the y-intercept placed at the end, you will need to substitute the coordinate values from one of the ordered pairs into the equation y = -3x + b. I chose to use the first ordered pair, so:

-5 = -3(2) + b (Multiply the slope by x to earn the new value)

-5 = -6 + b (Add the -6 to the -5 to isolate the b)

1 = b (b = 1) (Learn that b = 1)

Your final equation will be y = -3x + 1.

Answer:

The equation is y = -3x + 1.

Step-by-step explanation:

First, you have to find the gradient of the equation using the formula :

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Let (x1,y1) be (-2,7),

Let (x2,y2) be (2,-5),

[tex]m = \frac{ - 5 - 7}{2 - ( - 2)} [/tex]

[tex]m = \frac{ - 12}{4} [/tex]

[tex]m = - 3[/tex]

Next, we have to use the slope-form equation y = mx + b where m is gradient and b is constant. So we have to find the value of c by substituing any coordinates into the equation :

[tex]y = - 3x + b[/tex]

Let x = 2,

Let y = -5,

[tex] - 5 = - 3(2) + b[/tex]

[tex] - 5 = - 6 + b[/tex]

[tex]b = 6 - 5[/tex]

[tex]b = 1[/tex]
