This is a guess, so if it's not right, I completely apologize.
I suppose the answer is C) The 1st angle is a right angle; definition of _|_.
Answer:
no solution
Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
I'd use synthetic div. here, with 2 as my divisor:
________________
2 / 1 -11 18
2 -18
----------------------------
1 -9 0
Note that the coefficients of the missing factor are given here and are 1 and -9. Thus, (x-9) is the missing factor.
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2
Answer:
x = 2
Step-by-step explanation:
Given that:
Your score = 5
We have to find scores of opposite team let it be x
According to given conditions:
Opponents score: (1/2)x+ 4 = 5
By simplifying:
subtract 4 from both sides:
(1/2)x + 4 -4 = 5-4
(1/2)x = 1
Multiply both sides by 2 we get
2*(1/2)x = 1*2
x = 2
Proof:
(1/2)x+ 4 = 5
Put x= 2
(1/2)*2 +4 =5
1 +4 =5
5=5
Hence proved
I hope it will help you!
