Answer:
-1, -2
Step-by-step explanation:
Since multiplication by 0 will result in 0, any value of x resulting in 0
(-1+1)(-1+2)=0
0x1=0
(-2+1)(-2+2)=0
-1x0=0
Answer:
X= -1 or X= -3 . Probably the first one
Step-by-step explanation:
Answer:
x = - 6 or x = 2
Step-by-step explanation:
The absolute value function always returns a positive value. However, the expression inside can be positive or negative.
Given
| 2x + 4 | - 1 = 7 ( add 1 to both sides )
| 2x + 4 | = 8, thus
2x + 4 = 8 ( subtract 4 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
OR
-(2x + 4) = 8
- 2x - 4 = 8 ( add 4 to both sides )
- 2x = 12 ( divide both sides by - 2 )
x = - 6
As a check
Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.
x = 2 → | 4 + 4 | - 1 = | 8 | - 1 = 8 - 1 = 7 ← True
x = - 6 → | - 12 + 4 | - 1 = | - 8 | - 1 = 8 - 1 = 7 ← True
Hence the solutions are x = - 6 or x = 2
Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2
Answer:
Option D.) 236 degrees
Step-by-step explanation:
Angle GFE is half of the central angle. Measure of central angle is congruent to it's intersecting arc, therefore;
<em>2 * ∠GFE = Arc GE (?)</em>
2 * 118 = Arc GE (?)
<u>236 = Arc GE (?)</u>
Hope this helps!
