Answer:
- We're provided : F ( x ) = x² - 7 & we're asked to evaluate F ( - 3 ).
- All you need to do is to assume the value of x as ( - 3 ).
- When x = ( - 3 ) ,
- Multiplying a negative integer by a negative integer gives a positive integer!
- Hence , F ( - 3 ) = <u>2</u><u> </u> .

Solve for x.
Distribute the Parenthesis.
Combine Like Terms.
Add 1338 to both sides.
Subtract 668x from both sides.
![[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x](https://tex.z-dn.net/?f=%5B%28668x%2B900%29%2B1338%5D-668x%3D%5B%28672x-1338%29%2B1338%5D-668x)
Simplify.
Divide both sides by 4.
Simplify.
Hope this helps.

Answer:
Mid-point:
Equation:
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.
To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB: =
=
=
Multiplying slopes that are perpendicular with each other always results in -1.
By the point slope form:
Plug in the coordinates of the mid-point:
Equation:
Answer:
There are 45 library books in the classroom.
Step-by-step explanation:
The problem says that Marvin, Latoya and Abdulla each read 3/7 of the library books in the classroom. If Latoya read 3/7 of the books, we can form a proportion to determine the number of total library books in the classroom.
To solve for 'x', we can either cross-multiply and divide, or we can multiply the denominator by the same factor as the numerator to get a product of 15. In this case, the same factor would be 5, so 7 x 5 = 35. If we cross-multiply:
3x = (15)(7) or x = 35.
