10 points!!! Please answer 8 and 9 and hurry
lilavasa [31]

Answer:

Step-by-step explanation:

since EG bisects angle DEF

31 = x + 15

31 - 15 = x

x = 16 degree

6x - 4 = 56

6x = 56 + 4

x = 60/6

x = 10

Quick help: Explain how to solve the following system of equations. What is the solution to the system?
romanna [79]
-3x - 4y - 2z = 0
x + 3y + 2z = 1

-2x - y = 1

-4x - 4y - 2z = 10
3x + 4y +2z= 0

-x = 10. x = -10

-2(-10) - y = 1
20 - y = 1
-y = -19
y = 19

-10 + 3(19) + 2z = 1
-10 + 57 + 2z = 1
47 + 2z = 1
2z = -46
z= -23

check: 2(-10)+2(19)-23=-5
-20+38-23=-5
-43+38=-5
-5=-5

Sketch the curve represented by the parametric equations (indicate the orientation of the curve), and write the corresponding re
raketka [301]

Answer:

(See explanation below for further details).

Step-by-step explanation:

Let be a parametric curve represented by x = 3\cdot t - 5 and y = 5\cdot t + 1, where t is the parametric variable.

The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.

t = \frac{x+5}{3} and t = \frac{y-1}{5}

\frac{x+5}{3} = \frac{y-1}{5}

5\cdot (x+5) = 3\cdot (y-1)

5\cdot x +25 = 3\cdot y - 3

5\cdot x -3\cdot y = -28

The parametric equations represents a linear function (first-order polynomial).
