Answer:
the gradients are the most important features.
Step-by-step explanation:
if the linear functions are parallel with different constants, they won't intercept. If they are parallel with an equal constant, they are the same function. Any linear functions with different gradients will always intercept

a line of symmetry will connect a vertex and a midpoint of an opposite side
it has 7-fold symmetry.
<u><em>Explanation</em></u><span><u><em>: </em></u>
A line of symmetry is a line that we can use to <u>"fold"</u> a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex.
Since there are 7 vertices, there will be 7 lines of reflection.</span></span>
Step-by-step explanation:
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
1. 40-22=18
2.18/40=.45
3.45=45%
Answer:
She typed 32 words in her letter
Step-by-step explanation:
Assume that the letter has x words
∵ She typed x words in her letter
∵ She misspelled 8 words
∵ She misspelled 25% of the words she typed
∴ She misspelled 25% of x
→ That means 8 is equivalent to 25% of x
∴ 25% of x = 8
∴ 25% × x = 8
→ Change 25% to decimal by divide it by 100
∵ 25% = 25 ÷ 100 = 0.25
∴ 0.25 × x = 8
∴ 0.25x = 8
→ Divide both sides by 0.25
∵
= ![\frac{8}{0.25}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B0.25%7D)
∴ x = 32
∵ x represents the number of words that she typed in the letter
∴ She typed 32 words in her letter
