The slope is 5/2. You can find the slope by using y2-y1/x2-x1. 7-2/6-4= 5/2.

Answer:

  yes

Step-by-step explanation:

There are several ways to go at this.

My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.

Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

__

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.

  (((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0

The value of h(5) is zero, so x-5 is a factor of h(x).

25x+20y=455
x+y=20


20x+20y=400
-25x-20y=-455
-5x=-55
x=11
11+y=20
y=9

Solved it as well, sorry if I wasn't supposed to

Answer:

x = 10

Step-by-step explanation:

Use Pythagorean theorem to find the value of x

Focus only on one half of the triangle

if we slice the triangle in half, we get a right angle triangle

the base will now be 12/2 = 6

Pythagorean theorem says that a^2 + b^2 = c^2

plug 6 as a and 8 as b.

this should give you 100

now take the square root to find c (which equals x)

Ta-da!
