The unit rate for each situation is $5.00 for 1 pound, $8 for 1 pound, $65 for 1 pound, $2 for 1 pound, $18 for 1 pound, $108 for 1 pound

What is unit rate and how to compute it?

Unit rate is the rate for 1 unit and to compute the unit rate we divide the total price by the total number of elements

We are given certain price we have to find there unit rate

a) $45 for 9 pound

Divide both sides by 9 to find the unit rate

we get $5 for 1 pound

a) $24 for 3 pound

Divide both sides by 3 to find the unit rate

we get $8 for 1 pound

a) $390 for 6 pound

Divide both sides by 6 to find the unit rate

we get $65 for 1 pound

a) $42 for 21 pound

Divide both sides by 21 to find the unit rate

we get $2 for 1 pound

a) $180 for 10 pound

Divide both sides by 10 to find the unit rate

we get $18 for 1 pound

a) $864 for 8 pound

Divide both sides by 8 to find the unit rate

we get $108 for 1 pound

Hence the unit rates are for each situation is $5.00 for 1 pound, $8 for 1 pound, $65 for 1 pound, $2 for 1 pound, $18 for 1 pound, $108 for 1 pound

3) Thus, the answer is 6

For the given system of equations 4x + 6y=24 and 2x + 3y=8, there is no solution exists.

For the given system of equation,

4x + 6y =24  ......eq 1

and 2x + 3y = 8 ..... eq2

use elimination method.

Multiply eq 2 with 2 and subtract from eq 1.

0 = 16

But 0 ≠ 16, the system of equation becomes untrue.

As, the values o f the variables x and y are getting cancelled. So, the there is no solution existed for the given system.

Also,the ratio of 4x/2x = 2 and 6y/3y = 2 is same thus, no solution is possible for the system.

Now, when the we triple each side of the first equation 4x+6y=24, we have 12x+18y=72.

The new system 12x+18y=72 and 2x+3y=8

Then, also 12x/2x = 6 and 18y/3y = 6 is also same. Then, also the system of equation does not have any solution of the system.

Answer:

The answer should be x=2.6

Step-by-step explanation:

9x-9=3x+7

-first you should move the numbers so you can get all your x values on one side and all your regular numbers on the other like this

9x-3x=7+9

-What i basically did was i passed the 3x from the right side to the left side of the equation, since in adding the 3x originaly, when i pass it to the left side itll be subtracting. then i passed my -9 to the right side of my equation, since i was subtracting originaly ill have to now switch it to adding

-after you do this you are going to want to want to combine like terms

6x=16

-then you are going to want to devide on both sides so you can get x alone

x=2.6

∠GJI ≅ ∠LKF is proved below.

If two shapes are similar in size and shape, they are congruent. We can also state that if two shapes are congruent, then their mirror images are identical. If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent, or to be in the relation of congruence.

line 1 = y = 5/3 x - 6

Find the slope of the line by comaring it with y = mx+ b

m= 5/3

Line 2

Write the equation in the form y =mx +b and find the slope m

10x - 6y = 8

6y = 10x - 8

Divide through by 6

y = 10/6 x - 8/6

y = 5/3 x - 4/3

m= 5/3

Line 3

3y = 5x + 7

Also write in the form y =mx + b and find the slope m

y = 5/3 x + 7/3

m = 5/3

The number of children's tickets sold is 13750.

Let the number of children be x and the number of adults be y.

The total number of attendance at the amusement park is 25,000.

So we have an equation

x + y = 25000 ......(i)

The cost for children is $15 and the cost for adults is $35, and the total money earned by the park is $600,000.

So we have another equation,

15x + 35y = 600,000

3x + 7y = 120,000 ......(ii)

Multiplying equation (i) with 3 we get

3x + 3y = 75000

3x + 7y = 120,000

Now subtract both the equation we have,

4y = 45000

y = 11250

Now put the value of y in equation (i) we get

x + 11250 = 25000

x = 13750

Where x is the number of children's tickets sold.

Therefore the number of children's tickets sold is 13750.

Part A: The vertex, domain, and range of the function g(x) = |x-5|  is

( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).

Part B: The function f(x) = |x| is vertically shifted by 3 units to get the function h(x) = |x| + 3. The y - coordinate of the vertex is shifted by 3 units.

In Part A:

The given function is;

g(x) = | x - 5 |.

Now, The x - coordinate of the vertex will be:

x - 5 = 0

x = 5

Therefore, the y- coordinate of the vertex will be:

y = g(x) = | x - 5 |

y = g(7) = | 5 - 5|

y = 0

So, The vertex of the absolute function is ( 5, 0 ).

Since, All real numbers fall under the expression's domain, with the exception of cases where it is undefined. In this case, the phrase is defined even if there is no real number.

Hence, In Interval Notation the domain is;

⇒ ( - ∞ , ∞ )

And, The set of all legitimate y values is the range.

Hence, In Interval Notation the range is:

⇒ [0, ∞ )

Now, In Part B:

Function h(x) = |x| + 3 is the transformed version of the parent function

f(x) = |x|.

For the parent function f(x) = |x|, the vertex is ( 0, 0).

Since, The range of an absolute function in the form c( | ax + b | ) + k is

f(x) ≥ k.

Therefore, The range of the function f(x) = |x| is f(x) ≥ 0 and in interval notation is [ 0, ∞ ).

For the transformed function h(x) = |x| + 3.

The vertex of the function is ( 0, 3 ).

The range of function is h(x) ≥ 3 and in interval notation is [3, ∞ ).

Hence, the y coordinate of the vertex is transformed by 3 from f (x) to h(x).

So, Part A: The vertex, domain, and range of the function g(x) = |x-7|  is  

( 5, 0 ), ( - ∞ , ∞ ) and [0, ∞ ).

Part B: The function f(x) = |x| is vertically shifted by 2 units to get the function h(x) = |x| + 3. The y coordinate of the vertex is shifted by 3 units.

P=Present amount=$4739

r=interest rate = 0.051

n=number of compounding periods =12

The test statistic for the anova is an F test and it is said to be positively skewed which would be to the right of the F test statistic.

This is the term that is used to refer to the short form of the term that says analysis of variance.

The ANOVA is used to show the variation that would be in existence of a group of observations.

The F test is known to be positively skewed at all times. So we would have it that the P value would have to be to the right and not to the left in the ANOVA hypothesis.

Given data:

Draw the points on the graph paper as shown below.

Answer:

B. The graph is incorrect and the line should go through the point (3, 13.5)

Step-by-step explanation:

The equation is y = 4.5x

y = the y-axis/dependent variable

x = the x-axis/independent variable

4.5 x 1 = 4.5

4.5 x 2 = 9

4.5 x 3 = 13.5

Therefore the written ordered pairs would look like this.

(1, 4.5)

(2, 9)

(3, 13.5)

In the graph, (3, 13.5) is graphed as (13.5, 3) making the graph incorrect.

The statement which is true about the graph shown is that: the graph is incorrect and the line should go through the point (3, 13.5).

Generally speaking, the graph of any linear function is always modeled by a straight line and it indicates a proportional relationship because it starts from the origin (0, 0).

Mathematically, a proportional relationship can be represented or modeled by the following linear equation:

y = kx

Where:

At data point (4.5, 4.5), we have:

y = 4.5x

y = 4.5(4.5)

y = 20.25 (incorrect).

At data point (3, 13.5), we have:

y = 4.5x

y = 4.5(3)

y = 13.35 (correct).

Therefore, we can logically deduce that this graph is incorrect because its line didn't pass through the data point (3, 13.5).
