Use the substitution method to solve each linear system. 4x - 3y = -13,-2x + y = 4

Contact [7]

Answer:

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

Step-by-step explanation:

Given the system of the equations

$\begin{bmatrix}4x-3y=-13\\ -2x+y=4\end{bmatrix}$

Isolate x for for 4x-3y=-13

$4x-3y=-13$

$4x=-13+3y$

Divide both sides by 4

$x=\frac{-13+3y}{4}$

substitute y=5

$x=\frac{-13+3\cdot \:5}{4}$

$x=\frac{1}{2}$

The solutions to the system of equations are:

$x=\frac{1}{2},\:y=5$

Certain clouds form when temperatures fall below -62c. What is the temperature in degrees Fahrenheit? Temperature is_ Greece Fah

Vadim26 [7]

Solution: The value of temperature is -79.6 degree fahrenheit.

Explanation:

The temperature is given in degree celsius and we have find the temperature in degree fahrenheit. The formula to convert the degree celcius in degree fahrenheit is given below,

$F=32+\frac{9}{5} C$

Where, F is temperature in degree fahrenheit and C is temperature in degree celsius.

Since it is given that the temperature is -62 degree celsius. So put $c=-62$ in the above formula.

$F=32+\frac{9}{5} (-62)$

$F=32+\frac{(-558)}{5}\\F=32-111.6\\F=79.6$

Hence the value of temperature is -79.6 degree fahrenheit.

The table below shows the typical hours worked by employees at a company. A new employee is offered an annual salary of $37,000.

Mademuasel [1]

Answer:

Salaried pay is preferable for a new employee

Step-by-step explanation:

As per table, hours worked per week:

0+ 8.5+ 9.5+ 7.5+ 8+ 8.5+ 4 = 46

Employee gets paid for 46 hours per week:

$40*14 + (46- 40)*$21 = $686

Average yearly salary would be:

$686/7*365 = $35770

Comparing with annual salary, we see:

$37000 > $35770

As we see, hourly employees get paid less, so the new employee should choose annual salary option
