△ABC and △CDE similar right triangles. The coordinates of all the vertices are integers.
A. The slope of AC¯¯¯¯¯ is less than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
B. The slope of AC¯¯¯¯¯ is greater than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
C. The slope of AC¯¯¯¯¯ is equal to the slope of CE¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for AC¯¯¯¯¯ as for CE¯¯¯¯¯
D. The relationship between the slope of AC¯¯¯¯¯ and the slope of CE¯¯¯¯¯ cannot be determined, because the triangles are congruent.

Answers

Answer:

C.) The slopes are equal

Step-by-step explanation:

Since both of the triangles are similar right triangles they have the same slope, in order for triangles to be similar, you must be able to make them look the same. In this case triangle, CDE is a down-scaled version of triangle ABC meaning if you just multiplay all the vertices by the same (and correct) number it will make a triangle the same as ABC, therefore the triangles have equal slopes.

C I believe it’s the one that makes more sense

1) 7= 1+ 2p 2) -3p + 5= 8

Answers

P=3 and p=-1
First you subtract the number without a variable to the other side, so subtract one from seven, and subtract five from eight. After that just divide to make p by its self and you get the answer!!

Answer:

p=3 and p=-1

Step-by-step explanation:

1) 7=1+2p

Subtract 1 on both sides to isolate x.

7=1+2p

-1 -1

6=2p

Divide both sides by 2.

6=2p

/2 /2

3=p

2) -3p+5=8

Subtract 5 on both sides to isolate x.

-3p+5=8

-5 -5

-3p=3

Divide both sides by -3.

-3p=3

/-3 /-3

p=-1

Answers

1/a^2+a+1 put in fraction form

Answer:

1/36

Step-by-step explanation:

notice the first equation is the second equation squared.

For instance, look at the numerator: a squared is a^2

Look at the denominator: a^2 squared is a^4 and so on.

So if the second equation is 1/6, then you need to square it to have it equal the second equation: (1/6)^2 = 1/36

19 3/5 as a decimal SHOW YOUR WORK ALSO PLS!!!!

Answers

Answer:

19 3/5 = 19.6 decmial.

Step-by-step explanation:

Simplify the following:

19 + 3/5

Put 19 + 3/5 over the common denominator 5. 19 + 3/5 = (5×19)/5 + 3/5:

(5×19)/5 + 3/5

5×19 = 95:

95/5 + 3/5

95/5 + 3/5 = (95 + 3)/5:

(95 + 3)/5

95 + 3 = 98:

Answer: 98/5 = convert to decimal 19.6

Check:

Convert to a mixed number:

98/5

Divide 98 by 5:

5 | 9 | 8

5 goes into 9 at most one time:

| 1 | |

5 | 9 | 8 |

- | 5 | |

| 4 | 8 |

5 goes into 48 at most 9 times:

| 1 | 9 |

5 | 9 | 8 |

- | 5 | |

| 4 | 8 |

- | 4 | 5 |

| | 3 |

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:

| 1 | 9 | (quotient)

5 | 9 | 8 |

- | 5 | |

| 4 | 8 |

- | 4 | 5 |

| | 3 | (remainder)

The quotient of 98/5 is 19 with remainder 3, so:

Today, about 10 percent of children ages 6 or 7 begin developing signs of puberty, a condition known as precocious puberty.In the early 1900s, girls typically began menstruating at age 17. Today, girls typically begin around age 12. This trend has been attributed to the growing number of overweight children and a greater exposure to pollutants. Exposure to phthalates, artificial chemicals found in plastics, has also been cited as a cause. These chemicals disrupt the endocrine system by mimicking hormones in the body.Early puberty can have many negative side effects, including an increased risk of certain types of cancer, such as breast cancer. Children are often emotionally unprepared for the physical changes taking place in their bodies.
