Create an equivalent system of equations using the sum of the system and the first equation

ohaa [14]

Answer:

$\large\boxed{A.\ \left\{\begin{array}{ccc}-3x+y=12\\-2x+4y=18\end{array}\right}$

Step-by-step explanation:

$\underline{+\left\{\begin{array}{ccc}-3x+y=12\\x+3y=6\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad-2x+4y=18\\\\\text{therefore}\\\\\left\{\begin{array}{ccc}-3x+y=12\\-2x+4y=18\end{array}\right$

Please answer the area please

Nata [24]

The area of a trapezoid is:

$A = \frac{a + b}{2} h$

A = area

a = base 1

b = base 2

h = height

Area = unknown

base 1 = 2.5

base 2 = 7.5

height = 2.5

^^^Plug these numbers into the formula!

$A = (\frac{2.5 + 7.5}{2} )(2.5)$

A = (10/2)(2.5)

A = (5)(2.5)

A = 12.5

Hope this helped!

F(1)=6;f(n)=f(n−1)−2

ch4aika [34]

Answer: f(7) = f(4) + 3(3) = 15 + 9 = 24

Step by Step Explanation:

f(1) = 6

f(n) = f(n-1) + 3

f(2) = f(1) + 3 = 6+3 = 9

f(3) = f(2) + 3 = 12

f(4) = f(3) + 3 = 15

Each term is 3 more than the previous one

Therefore to get from the 4th term to the 7th term you will add 3

For a total of 3 more times.

f(7) = f(4) + 3(3) = 15 + 9 = 24

Hope this helps

Please help me <br> I have to solve the triangle with the law of sines

Nikitich [7]

Check the picture below.

and since a triangle has a sum of 180° for all interior angles.

A = 180 - 39.34 - 25

A = 115.66

$\bf \cfrac{sin(25^o)}{44}=\cfrac{sin(A)}{a}\implies \cfrac{sin(25^o)}{44}=\cfrac{sin(115.66^o)}{a} \\\\\\ a\cdot sin(25^o)=44\cdot sin(115.66^o)\implies a=\cfrac{44\cdot sin(115.66^o)}{sin(25^o)} \\\\\\ a\approx 93.8452\implies \stackrel{\textit{rounded up}}{a = 93.85}$

make sure your calculator is in Degree mode.
