When it says f(x) and x is replaced with a number, it just means replace the x in the equation with that number.

(Simpler) Way to solve using the graph:
Go to where x = -4 (4 spaces right of the center) and look above and below it for the line. Wherever the line is, is the answer. So f(-4) = 2 because when x is -4, the y value is 2.

Example of solving with an equation:
f(3) = 2
f(3) = 2(3)
f(3) = 6

You create an equation for the line, than substitute -4 in to the equation.

Answer:

(x - 5)^2 + (y - 7)^2 = 13^2

or

(x - 5)^2 + (y - 7)^2 = 169

Step-by-step explanation:

Well, the center origin of the circle is given (h,k) =  (5,7).

We have to find our radius as they gave us a point. from origin to the edge of the circle.

Using the formula: (x - h)^2 + (y - k)^2 = r^2

Plug in our (h,k) = (5,7) and (x,y) =  (10,19) to solve for radius.

(x - h)^2 + (y - k)^2 = r^2

(10 - (5))^2 + (19 - (7)^2 = r^2

(5)^2 + (12)^2 = r^2

25 + 144  = r^2

r^2 = 169

r = 13

Which expression uses the associative property to make it easier to evaluate? (50points)
Naily [24]

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

Step-by-step explanation:

Given expression is:

8.(\frac{1}{4}.\frac{3}{5})

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

a.(b.c) = (a.b).c

So applying the associative property on given expression

8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}

Hence,

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

If x is a number that satisfies 4x+3=18, can x be equal to 3? explain.
Akimi4 [234]
The answer is no. because is you substitute the value 3 in for x into the equation and solve you get,

4(3)+3=18 which says 12+3=18 15=18 and that is an untrue statement. 
Hope this helps explain the concept so you understand! Any questions feel free to ask! Please rate if I helped you! thank you so much!!
