1) -x + 4 = -2x - 6
Add(2x)
x+4=-6
Subtract(4)
x = -10
<u>Check your work</u>
-(-10)+4=-2(-10) - 6
10+4=-2(-10) - 6
14=-2(-10)
14=20 - 6
14=14
Correct :)
2) 4R - 4 = 3R + 10
Add 4
4R=3R+14
Subtract 3R
R = 14
<u>Check your work</u>
4(14)-4=3(14)+10
56-4=3(14)+10
52=3(14)+10
52=42+10
52=52
Correct :)
3) 2Y - 3 = Y - 4
Add 3
2Y = Y - 1
Subtract Y
Y = -1
<u>Check your work</u>
2(-1)-3=-1-4
-2-3=-1-4
-5=-5
Correct :)

<span>The general form of quadratic equation with real
coefficients and leading coefficient 1, has x = -bi as a root
=> x = <u>-b + </u></span><u>√ b^2 – 4 ac</u><span>
2a
It is also written as:
=> ax^2 + bx + c = 0
Quadratic equation involves unknown numbers which is x, the numbers which a, b
and c are called coeffecients.
There are also quadratic factorization where you factor the polynomial give to
be able to get the value of the equation.</span>
Answer:
1 possibility is there for the the position of the fourth vertex.
Step-by-step explanation:
11/8 if I'm not wrong
...
Corresponding sides must be proportional and corresponding angles are congruent.
