Answer:

undefined

Step-by-step explanation:

4 - 9 = x - 2

-5 = x - 2

-3 = x

this is a vertical line (parallel to the y-axis) at x = -3.

that means the slope of this line is "undefined". or some would call it "infinite".

as the slope is the ratio of y/x describing how many units y changes, when x changes a certain amount of units.

now the change of x for this line is constant 0.

so, we have a slope y/0, which is undefined.

If f(x)=8-10x and g(x)=5x+4, what is he value of (fg)(-2)

Lana71 [14]

Answer:

168

Step-by-step explanation:

We would like to multiply these two expressions together and then substitute -2 in for x to solve.

f(x) * g(x) = (8 - 10x) * (5x + 4)

We will use FOIL (first, outer, inner last):

(8 - 10x) * (5x + 4) = 8 * 5x + 8 * 4 + (-10x) * 5x + (-10x) * 4

Combining terms, we get:

f(x) * g(x) = 32 - 50x²

Plug -2 in for x:

32 - 50 * (-2)² = 32 - 50 * 4 = 32 - 200 = -168

The answer is thus 168.

ANSWER QUICK PLEASE If f(x) = |x – 5| + 3, find f(2).

Ivanshal [37]

Answer:

SO if f(x)= |x-5|+3 then F(2)= 6

Step-by-step explanation:

These signs | | mean that it is an absolute value equation. SO that means any negative will automatically change to positive values and positive values will stay at positive values. You are supposed to substitute 2 in for x and if you do 2-5 then that is negative 3 but it changes to positive 3 and add three and then f(2)= 6

What is 710,200 written in word form

Julli [10]

For this case we have the following number:
710200
We are going to decompose this number as the sum of three numbers:
 $710200 = 700000 + 10000 + 200
$
 Let's now write each number:
70000: seven hundred thousand
10000: ten thousand
200: two hundred
Therefore, the complete expression is:
Seven hundred ten thousand two hundred
Answer:
Seven hundred ten thousand two hundred
