Substitute (–5, 0.5) into x – 4y = –7 to get .

lesya [120]

Answer:

-7

Step-by-step explanation:

Coordinates are listed as (x,y) so x = -5 and y = .5

If you substitute the numbers in place of the letters, you get:

(-5) - 4(.5) = -7

-5 - 2 = -7

-7 = -7

Name the property of equality that justifies the statement: if a+b=c, then a=c-b

SashulF [63]

1. a = b means a is equal to b.
2. a ≠ b means a does not equal b.Operations1. Addition: If a = b then a + c = b + c.2. Subtraction: If a = b then a – c = b– c.
3. Multiplication: If a = b then ac = bc.
4. Division: If a = b and c ≠ 0 then a/c = b/c.

Help me plz I would really appreciate it!

Given,
$x = \frac{7}{9} \: \: \: y = \frac{5}{6} \\ \\ - 2y + x \\ = - 2( \frac{5}{6} ) + \frac{7}{9} \\ = - \frac{5}{3} + \frac{7}{9} \\ = \frac{ - 15 + 7}{9} \\ = \frac{ - 8}{9}$

Hope you could get an idea from here.

Please answer soon I need this answer very quickly for math. Thank you!

Kazeer [188]

a. First five terms: 9,13,17,21,25

b. Sum of first 25 terms = 1425

c. The given sequence is an arithmetic sequence because the common difference between two consecutive terms is same.

Further explanation:

Given

Formula of sequence

$a_n=4n+5$

1. First 5 terms:

For first 5 terms, we have to put n=1,2,...5,

So,

$For\ n=1\\a_1=4(1)+5\\=4+5\\=9\\For\ n=2\\a_2=4(2)+5\\=8+5\\=13\\For n=3\\a_3=4(3)+5\\=12+5\\=17\\For\ n=4\\a_4= 4(4)+5\\=16+5\\=21\\For\ n=5\\a_5=4(5)+5\\=20+5\\=25\\First\ 5\ terms\ are: 9,13,17,21,25$
