Answer:
x=2,y=−1
Step-by-step explanation:
Solve for y in the first equation.
y=−9x/11+7/11
0=−2y+10−6x
Replace all occurrences of y with −9x/11+7/11 in each equation.
0=−48(x−2)11
y=−9x11+711
Solve for x in the first equation.
x=2
y=−9x/11+7/11
Replace all occurrences of x with 2 in each equation.
y=−1
x=2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(2,−1)
The result can be shown in multiple forms.
Point Form:
(2,−1)
Equation Form:
x=2,y=−1
Answer:
The answer is 72
First you find E=180-130=50
Then you add all the angles and subtract from 360
102+100+50=252
360-252=108
then you do 180-108=72
Angle four is 30° and angle 7 is 150! angle four equals 30° because a straight line equals 180, and 180-150=30. angle 7 is 150 through corresponding angles
B because distributive property goes like this:
a(b+c)
a(b)+a(c)
That's just an example though
