Answer:
Step-by-step explanation:
If a line is parallel to another it must have the same slope
The slope/intercept form of a line is y = mx + b where m is the slope and b the y intercept
The line y = 2x + 5 has slope 2
So the slope of the line that passes through (2,3) must also have the slope 2
We have
y = 2x + b; Substituting x =2, y =3 in this equation gives us
3 = 2 (2) + b or b = -1
Hence the equation of the line is
y = 2x -1
Cross-check
Substitute for x = 2 ==> y = 2(2) - 1 = 3 which is consistent
Answer:
3 tenths
Step-by-step explanation:
One candy bar
= 1 candy bar
= 1.0, or 10 tenths (one tenth is 0.1)
If Theo eats 0.7 of a candy bar, we know that
1.0 - 0.7 = 0.3
0.3 = 3 *0.1 (one tenth)
Therefore, the answer is 3 tenths.
Answer: (5) -5 > -18
Step-by-step explanation:
- <u>The farther the negative number is from 0, the smaller it becomes.</u>
- <u>Negative numbers will be smaller than positive numbers, since they're smaller than 0.</u>
-5 is 5 away from zero, making it larger than -18 since it's closer to 0, while -18 is 18 away from zero.
Answer:
There was 62.23% change in radius as the ion formed.
Step-by-step explanation:
Given
Radius of Aluminium 
atom = 143 pm
Radius of Aluminium 
atom = 54 pm
Change is the radius = Radius of Aluminium atom - Radius of Aluminium atom = 143 -54 = 89
Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium atom and multiply by 100 we get
% Change is the radius = 
Hence there was 62.23% change in radius as the ion formed.
