Answer:
Step-by-step explanation:
Neptune is about 2,700,000,000 miles from Earth.
Mercury is about 135,000,000 miles from Earth.
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. The power is the number of decimal places you move.
1) 2,700,000,000 = 2.7 x 
135,000,000 = 1.35 x 
2)
You can see there is only one extra 0 on top, the rest will cancel so you have:
It's 20x farther to Neptune from Earth, than it is to Mercury from Earth.
Hello! And thank you for your question!
First we are going to expand the equation:
<span>−2<span>m^<span><span>2</span><span></span></span></span>−2mn+8m−10m+10n+nm+4<span>n<span><span>^2</span><span></span></span></span>−5n
Then we are going to combine like terms:
</span><span><span>−2<span>m<span><span>^2</span><span></span></span></span>+(−2mn+mn)+(8m−10m)+(10n−5n)+4<span>n<span><span>^2</span><span></span></span></span></span>

Then finally, simplify:
−2<span>m<span><span>^2</span><span></span></span></span>−mn−2m+5n+4<span>n<span>^<span>2

Answer: B. 3x+ 2y = 12
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m represents the slope of the line.
c represents the y intercept
The equation of the given line is
3x + 2y = 4
2y = -3x + 4
Dividing through by 2, it becomes
y = - 3x/2 + 2
Comparing with the slope intercept form, slope = - 3/2
If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (6, - 3) is - 3/2
To determine the y intercept, we would substitute m = - 3/2, x = 6 and y = -3 into y = mx + c. It becomes
- 3 = - 3/2 × 6 + c
- 3 = - 9 + c
c = - 3 + 9
c = 6
The equation becomes
y = -3x/2 + 6
Cross multiplying by 2, it becomes
2y = - 3x + 12
3x + 2y = 12
Answer:
i think the answer would be 8 2/5
Step-by-step explanation:
but i also need to know what the other uestions are saying
Answer:
False
Step-by-step explanation:
The angle between a tangent and radius is right.
Use the converse theorem of Pythagoras to determine.
If the square on the longest side is equal to the sum of the squares on the other two sides then the triangle is right and the segment is a tangent.
longest side = 13.1 ⇒ 13.1² = 171.61
11.3² + 6.65² = 127.69 + 44.2225 = 171.9125
Since 171.61 ≠ 171.9125 the line is not a tangent
