Answer:
X = 8
Step-by-step explanation:
Since the shape is a parallelogram the opposite sides are equal
The equation is:
Solve:
- 6 + 10 = 2x -10 + 10
- 16 = 2x
- 2x = 16
- Divide by 2 on both sides
- <u>x = 8</u>
Check:
- 2(8) - 10 = 6
- 16 - 10 = 6
- 6 = 6
- CD = BE
- 6 = 6
Answer:
last option
Step-by-step explanation:
imagine a number line

-2.34 would be found somewhere over there
If <em>h(x)</em> is the inverse of <em>f(x)</em>, then by definition of inverse function, we have
<em>f(h(x))</em> = <em>x</em>
By definition of <em>f(x)</em>, composing <em>f</em> with <em>h</em> gives
<em>f(h(x))</em> = 2 <em>h(x)</em> - 10
Solve for <em>h(x)</em> :
<em>x</em> = 2 <em>h(x)</em> - 10
2 <em>h(x)</em> = <em>x</em> + 10
<em>h(x)</em> = (<em>x</em> + 10)/2
<em>h(x)</em> = <em>x</em>/2 + 5
So... whichever option most closely resembles this is the correct one. It's hard to tell exactly which one that would be.
Answer:
In step 3
4m = 4 + 4n
-4m = -32 -8n. (step 2)
If you add -4m, 4m you end up with
-4m+4m=-32 -8n + 4n +4
In step 3. the 4 was not added
continuing to solve 4n=-28, n=-7
