Match the following real numbers with the proper combination of number types on the right.

Please help me with these 19 and 20 and tell me what you use to get the answer

ss7ja [257]

36 + h = 75...subtract 36 from both sides
h = 75 - 36
h = 39

-176 = h + (-219)
-176 = h - 219....add 219 to both sides
219 - 176 = h
43 = h

Factoring , <br> a² +4a - 5

givi [52]

the factors of the term $a^2+4a-5$ are $(a-1)(a+5)$

Step-by-step explanation:

We need to find factors of the term: $a^2+4a-5$

For finding factors:

We need to break the middle term such that their product is equal to product of first and last term and their sum is equal to middle term

Breaking the middle term and finding factors:

$a^2+4a-5$

$=a^2+5a-a-5$

$=a(a+5)-1(a+5)$

$=(a-1)(a+5)$

So, the factors of the term $a^2+4a-5$ are $(a-1)(a+5)$

At what point is the function y=(x+3)/(x^(2)-7x+12) continuous

nika2105 [10]

If a function is defined as

$h(x)=\dfrac{f(x)}{g(x)}$

where both $f(x),g(x)$ are continuous functions, then $h(x)$ is also continuous where defined, i.e. where $g(x)\neq0$

So, in your case, this function is continous everywhere, except where

$x^2-7x+12=0$

To solve this equation, we can use the formula $x^2-sx+p=0$

It means that, if the leading terms is 1, then the x coefficient is the opposite of the sum of the roots, and the constant term is the product of the roots.

So, we're looking for two terms whose sum is 7, and whose product is 12. These numbers are easily found to be 3 and 4.

So, this function is continuous for every real number different than 3 or 4.

HOOK is a word that has horizontal line symmetry since it is made up of letters that each have horizontal line symmetry. Can you

storchak [24]

Another word that has horizontal line symmetry is "book" and it is possible to form words with vertical line symmetry.

<h3>What is horizontal line symmetry in letters?</h3>

This implies that by dividing the letter in half using a horizontal line both sides would be the same. Lettters with horizontal line symmetry include:

H
K
O
E
B
C

<h3>What are some words with these symmetry?</h3>

Hood
Book
Cook
Bee

<h3>Are words with vertical line symmetry possible?</h3>

Yes, they are because there are many letters that have this symmetry such as V, T, A, O, M, I, H. For example you can create the words:

Hi
Mum
Hit
