Line A goes through (-6. 7) and has a y-intercept of -3. Line B is perpendicular to Line A and goes
through (-8,3). Write an equation in slope-intercept form for Line B.
this is for a study guide(not graded) thanks!
You can't find slope intercept form because it is perpendicular so the equation is x= -8

You are calculating how many seats there are at Camp Nou in Barcelona, Spain. You count that there are 3,300 rows. Each row has 30 seats. How many seats are there in the whole stadium?
Answer:
This should be a simple math problem if I didn`t miss understand anything the answer should be 99000
Step-by-step explanation:
99000 I think
Answer:
99,000
Step-by-step explanation:
If there are 30 seats in each row, you must multiply 30 by the number of rows there is. There are 3300 rows. Therefore, the answer to 3300 x 30 would be 99000.

write the factors of the following expression x3 (2a‐6)+x2 (2a-6)
Given:
The expression is
[tex]x^3(2x-6)+x^2(2x-6)[/tex]
To find:
The factors of the given expression.
Solution:
We have,
[tex]x^3(2x-6)+x^2(2x-6)[/tex]
First taking [tex](2x-6)[/tex] common, the given expression can be written as
[tex]=(2x-6)(x^3+x^2)[/tex]
Taking [tex]x^2[/tex] common from [tex](x^3+x^2)[/tex], we get
[tex]=x^2(2x-6)(x+1)[/tex]
Therefore, the factors of the given expression are [tex]x^2(2x-6)(x+1)[/tex].

You are testing two scales for accuracy by weighing two different objects.
Use the drop-down menus to complete the statements about the scales' accuracy.
Answer:
This is because the object on the 1st scale weighs (more) than the object on second scale, each pound of error results in a (lesser) percent error. The first scale was (10) pounds off the second scale,was (3) pounds off, so 1st scale was (10)% off 2nd scale was (12)% off.
Answer:
Because the object on Scale 1 weighs more than the object on Scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and Scale 2 was 3 pounds off, so Scale 1 was 10% off and Scale 2 was 12% off.

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there
Answer:
60,949,324,800
Step-by-step explanation:
We solve the above question using Permutation formula
The formula for Permutation =
nPr = n!/(n - r)!
Total Amount in a Set (n) = 20 persons
Amount in each Sub-Set (r) = 9 batting order
Hence:
20P9 = 20!/(20 - 9)!
= 60,949,324,800
Therefore, the different batting orders they would have are: 60,949,324,800

Step-by-step explanation:
log (x2 - 1) - log (2x + 2) = 0
Answer:
x=3
Step-by-step explanation:
log (x^2 - 1) - log (2x + 2) = 0
Add log (2x + 2) to each side
log (x^2 - 1) = log (2x + 2)
Since the logs with the same base are equal the x^2 -1 must equal 2x+2
x^2 -1 = 2x+2
Subtract 2x+2 from each side
x^2 -1 -2x-2 = 2x+2 -2x-2
x^2 -2x-3 = 0
Factor
What number multiplies to -3 and adds to -2
-3 *1 =-3
-3+1 =-2
(x-3) (x+1) =0
Using the zero product property
x-3 =0 x+1 =0
x=3 x=-1
Check to see if solutions are valid
x = -1
log ((-1)^2 - 1) - log (2*-1 + 2) = 0
log(0) - log 0 = 0
Log 0 is undefined x =-1 not a valid solution
x = 3
log ((3)^2 - 1) - log (2*3 + 2) = 0
log(8) - log 8 = 0
valid
