Find the solution of the system of equations.
10a + 10y = 40
5x + 3y = 8
Using elimination

The slope and a point of a line are given then the equation of a line can be found. So the answer is true.

The equation of a line:

The equation of a line means an equation in x and y whose solution set is a line in the (x,y) plane. The most popular form in algebra is the "slope-intercept" form. y = mx + b. This in effect uses x as a parameter and writes y as a function of x: y = f(x) = mx+b.

Here we have to get to know if the slope and a point on a line are given then we can find the equation of a line or not.

Let us assume m is the slope of a line and (x1, y1) is the point on a line.

By this, we get the equation:

y- y1 = m( x - x1)

Therefore from the slope and a point on a line, we can find the equation of a line.

Step-by-step explanation:

if x = -2

= 9x² - 4x - 3

= 9 ( -2)² - 4 ( -2 ) - 3 [ x = -2 ]

= 9 × 4 + 8 - 3

= 36 + 8 - 3

= 44 - 3

= 41

Answer:

The absolute value of any number will always be positive meaning that if you start with a positive number the sum of its absolute value will not be zero. Although if you start out with a negative number the sum of its absolute value will be zero.

Step-by-step explanation:

Nikki is incorrect because: if you combine a number and its absolute value, it won't give you zero.

The absolute value of a number is the positive value of that number. i.e.:

If \(-a\) is a number, absolute value of \(-a\) is \(a\).

Thus:

Therefore, using 5 as an example:

Absolute value of positive 5 (5) = 5.

Combine positive 5 (+5) with its absolute value (5), that is:

5 + 5 = 10

Therefore, Nikki is wrong because if you combine a positive number with its absolute value, it won't give you zero.

Answer:

7/4, 9/4, 11/4, 13/4

Step-by-step explanation:

+ In an arithmetic sequence, to find the pattern you must subtract a term from the term after it to find the common difference.

3/4 subtracted from 5/4 is 2/4

1/4 subtracted from 3/4 is 2/4

+ So the common difference is 2/4 (Aka 1/2, but you want to keep the same denominator)

+ Therefore, between each new term, you add 2/4

1/4, 3/4, 5/4, 7/4, 9/4, 11/4, 13/4... and so on

Answer:

$160

Step-by-step explanation:

Diane sold some stuffs at a garage sale.

Let the total value of the money Diane made = x

She spent one-half of the money she made on a new bicycle.

Amount spent on a Bicycle = 1/2 × x = 1/2x

Next,

Amount left

= x - 1/2x = 1/2x

She spent one-half of what was left on a portable stereo.

Amount spent spent on Portable stereo

= 1/2 × 1/2x

= 1/4x

If Diane had $40.00 left,

Hence:

The fraction of what was left is calculated as:

= x - (1/2x + 1/4x)

= x - (3/4x)

= 1/4x

Hence:

1/4x = $40

We can find the value of x now.

1/4 × x = $40

x/4 = $40

x = $40 × 4

x = $160

Therefore, the amount she made from the garage sale is $160

Step-by-step explanation:

To retrieve the names of projects with an employee working more than 15 hours, you can use the following SQL query:

SELECT project.name FROM project

JOIN assignment ON project.id = assignment.project_id

JOIN employee ON assignment.employee_id = employee.id

WHERE assignment.hours > 15;

The query uses the SELECT statement to retrieve the name column from the project table. It performs joins with the assignment and employee tables using the appropriate foreign keys (project.id, assignment.project_id, assignment.employee_id, and employee.id). The JOIN keyword is used to combine the tables based on their relationships.

The WHERE clause specifies the condition assignment.hours > 15 to filter the assignments where an employee has worked more than 15 hours. Only the projects meeting this condition will be included in the result.

By executing this query, you will retrieve the names of projects that have at least one employee working more than 15 hours on them.

Answer:

7.5 laps

Step-by-step explanation:

First, you wanna figure out how many yards is in one lap

to do this, you would multiply 100 and 4 (four because there's four equal sides  in one lap)

100 x 4 = 400

You know their speed is 5 yards per second, so you wanna find out how many seconds they will be running

to do this, you multiply 60 (sixty because there's sixty seconds in one minute) and 10 (ten because that's the given amount of minutes)

60 x 10 = 600 seconds

now to found out how much they will run in 10 minutes you will multiply 600 by 5

600 x 5 = 3000 yards

now to find how many laps this is, you can divide 3000 yards by 400 yards

3000 ÷ 400 = 7.5 laps

Let:

M = Total money = $20.56

Ca= Cost of the apple = 79 cents = $0.79

Cg = Cost of the granola bar = $1.76

Ms = Total money spent

Mr = Remaining money

So, the total money spent will be:

Ms = Ca + Cg = $0.79 + $1.76 = $2.55

And the remaining money will be:

Mr = M - Ms = $20.56 - $2.55 =$18.01

The nurse should infuse argatroban at a rate of approximately 42.41 ml/hr.

To calculate the infusion rate of argatroban in ml/hr, we need to convert the weight of the patient from pounds to kilograms and then use the ordered dose to determine the infusion rate. Here are the steps:

1. Convert patient weight from pounds to kilograms:

  187 lbs * (1 kg / 2.2046 lbs) = 84.82 kg (rounded to two decimal places)

2. Calculate the total dose per minute:

  2 mcg/kg/min * 84.82 kg = 169.64 mcg/min

3. Convert the total dose from micrograms to milligrams:

  169.64 mcg/min * (1 mg / 1000 mcg) = 0.16964 mg/min

4. Determine the infusion rate in ml/hr:

  Since the pharmacy provided argatroban in a concentration of 100 mg/250 ml, we can set up a proportion:

  0.16964 mg/min * (250 ml / 100 mg) * (60 min / 1 hr) = 42.41 ml/hr (rounded to two decimal places)

Therefore, the nurse should infuse argatroban at a rate of approximately 42.41 ml/hr to provide the desired dose for JK.

The alternate format for writing exponents is with logarithms. A number appears base-based logarithm is approximately equivalent to another number. A logarithm performs exponentiation's exact opposite function.

1. Rule of product: According to this rule, adding the individual logarithms of two logarithmic values results in the multiplication of those values.

\(Log_b (mn)= log_b m + log_b n\)

2. Rule of division: The difference between each logarithm is equivalent to the division of two logarithmic values.

\(Log_b \left(\frac{m}{n}\right)= log_b m - log_b n\)

3. The Power/Exponential Rule: According to the exponential rule, the exponent times the logarithm of m's logarithm is equivalent to m's logarithm with a reasonable exponent.

\(Log_b (m^n) = n log_b m\)

4. A new fundamental rule:

\(Log_b m =\frac{log_a m}{log_a b}\)

5. Rule of the base swap:

\(log_b (a) = \frac{1}{log_a (b)}\)

Answer:

Step-by-step explanation:

The product of a negative two and a positive three is equal to negative six (-6).

The direction vector of l is <2, 5, 3>, so the projection of the vector from (0, 0, 0) to (x, y, z) onto this direction vector is:

proj<0, 0, 0>(2, 5, 3)/||<2, 5, 3>||^2 * <2, 5, 3> = <0, 0, 0>

To find a point on the line l that is parallel to it, we simply need to choose any value of t and plug it into the parametric equations. Let's choose t = 1, then we have:

x = 5 + 2(1) = 7

y = 5(1) - 4 = 1

z = 3 + 3(1) = 6

So P = (7, 1, 6) is a point on the line l that is parallel to it.

To find a point Q at which the line and l are perpendicular, we need to find the point on l that is closest to the given point (0, 0, 0). This can be done by finding the projection of the vector from (0, 0, 0) to a point on l onto the direction vector of l. The direction vector of l is <2, 5, 3>, so the projection of the vector from (0, 0, 0) to (x, y, z) onto this direction vector is:

proj<0, 0, 0>(2, 5, 3)/||<2, 5, 3>||^2 * <2, 5, 3> = <0, 0, 0>
