The radical equation among the following equations will be  7√ x = 14 as it is the only equation that has a radical variable that is √ x.

A radical equation is an equation which has at least one variable to be put on in a radical form.

In this question, we have only one kind of variable which is x. So, we will only analyze that variable only.

Now, we need to find the equation where x is in the radical form.

The radical form can be expressed with square root symbol.

The option with √ x would be only 7√ x = 14.

Therefore, the radical equation among the following equations will be  7√ x = 14 as it is the only equation that has a radical variable that is √ x.

Answer:

So, the triangles cannot be proven congruent

Step-by-step explanation:

Congruence Theorems

Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.

The triangles shown in the figure have two clear congruent angles as marked in red color. The third angles located at point P is also congruent because they are vertical angles or opposite angles.

Being all three angles of the same measure, it proves both triangles are similar, but not necessarily congruent. The side lengths may be of the same measure, but they could also be proportional.

So, the triangles cannot be proven congruent

function i dont know im looking for the same answer but im pretty sure his salary is going to be 41,960 if you multiply the raise by 6 and 43,520 if you multiply the salary by 7

Step-by-step explanation:

The required Joe's salary will be represented by y = 32600 + 1560(x - 2001) and his salary in the year will be $41,960.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let Joe's salary after x years be y,
According to the question,
y = 32600 + 1560(x - 2001)

Now,
For year x = 2007
Joes income,
y = 32600 + 1560(2007 - 2001)
y = 32600 + 1560(6)
y = $41,960

Thus, the required Joe's salary will be represented by y = 32600 + 1560(x - 2001) and his salary in the year will be $41,960.

The perimeter of a rhombus with vertices p(-2, -3) ,Q(1,1) ,R(4,-3),S(1,-7). is 20 units

A rhombus is a quadrilateral that has all its sides equal to each other.

The rhombus has 4 sides and all it sides are equal.

Therefore,

perimeter of a rhombus = 4l

where

Therefore,

using p(-2, -3) ,Q(1,1)

l = √(1 + 3)² + (1 + 2)²

l = √4² + 3²

l = √16 + 9

l = √25

l = 5 units

Therefore,

perimeter of the rhombus = 4(5) = 20 units

The pay at each bank for the given month is $56.5 to Bank A and $47.5 to Bank B.

For the statement based question first of all try to find out that what is given in the statement and what we have to find out. Now, try to form the statements in the mathematical notation and then solve the equations by performing certain mathematical and algebra operations according to need.

In the question statement,

It is given that total number of transactions are 35 in a given month and pay for 2 banks are given to us. we need to calculate the total payout of transactions for both the banks.

Bank A charge $25 monthly fee on a checking the accounts, plus

$ 0.90 for each transaction.

As Charmaine makes 35 transactions.

Total charges of bank A= $25 + (0.9)35

Total charges  of bank A= $25+31.5 = $56.5

Also,

Bank B charge $30 monthly fee on a checking the accounts, plus

$ 0.50 for the each transaction.

Total charges of bank B= $30 + (0.5)35

Total charges of bank B= $30+17.5

Total charges of bank B= $47.5

The difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n

Given,

The two expressions are:

a = 3n³ + 4n² - 9

b = -2n³ + 4n - 9

We have to find a - b:

That is,

(3n³ + 4n² - 9) - ( -2n³ + 4n - 9)

Open the bracket and multiply (-) with the terms.

That is,

3n³ + 4n² - 9 + 2n³ - 4n + 9

Now solve the expression:

We get,

3n³ + 4n² + 2n³ - 4n

Add 3n³ and 2n²

Then,

5n³ + 4n² -4n

Therefore, the difference between 3n³ + 4n² - 9 and -2n³ + 4n - 9 is 5n³ + 4n² - 4n

Answer: he works 37 hours in job A, and 22 hours in job B.

Step-by-step explanation:

Let's define the variables:

A = number of hours that he works at Job A

B  = number of hours that he works at Job B.

We know that he works a total of 59hr per week, then we have:

A + B = 59

And we also know that he makes $494 in one week, then we have the equation:

A*$8 + B*$9 = $494.

Then we have the system of equations:

A + B = 59

A*$8 + B*$9 = $494

To solve this with an augmented matrix, we need to turn these equations into a matrix, where we only write the coefficients as follows:

[tex]\left[\begin{array}{cccc}1&1&I&59\\8&9&I&494\end{array}\right][/tex]

(The I's should represent a line for the augmented matrix, that line separates the values of the coefficients to the right value of each equation)

The first column represents the A coefficients, the second column represents the B coefficients.

To solve this, we want to get something of the form:

[tex]\left[\begin{array}{cccc}1&0&I&x\\0&1&I&y\end{array}\right][/tex]

Where x and y are our solutions.

To do it we can just do: Column 2 - 8*column 1, this will get us to:

[tex]\left[\begin{array}{cccc}1&1&I&59\\8 - 8*1&9 - 8*1&I&494 - 8*59\end{array}\right][/tex]

=

[tex]\left[\begin{array}{cccc}1&1&I&59\\0&1&I&22\end{array}\right][/tex]

Now we can do: Column1 - column2, to get

[tex]\left[\begin{array}{cccc}1 - 0&1 - 1&I&59 - 22\\0&1&I&22\end{array}\right][/tex]

[tex]\left[\begin{array}{cccc}1&0&I&37\\0&1&I&22\end{array}\right][/tex]

Then the solutions are:

1*A =37

1*B = 22

This means that he works 37 hours in job A, and 22 hours in job B.

The maximum walking speed of the Giraffe is 1.41 times greater than the maximum walking speed of the Hippopotamus

From the question, we are to determine how much greater the maximum walking speed of Giraffe is to that of Hippopotamus

From the give information,

The maximum walking speed, S, is given by

S = √gL

Where g = 32ft/sec
and L is the length of the animal's leg

Thus,

For a Giraffe with a leg length of 6 feet

S = √32×6

S = √192

S = 13.856 ft/sec

For a Hippopotamus with a leg length of 3 feet

S = √32×3

S = √96

S = 9.798 ft/sec

Now, we will determine how many times greater 13.856 is than 9.798

13.856/9.798 = 1.41

Hence, the maximum walking speed of the Giraffe is 1.41 times greater than the maximum walking speed of the Hippopotamus
