Determine the solution to the system of equations graphed below and explain your reasoning in complete sentences.

Anarel [89]

Answer:

(0, -3)

Step-by-step explanation:

The solution to the system of equations is the point at which they intersect. The problem statement tells you that point is (x, y) = (0, -3).

Often, for a system defined using functional notation, we don't care about the value of the function. We only care about the value of x where the functions have the same value. That is ...

the solution to f(x) = g(x) is x = 0.

Center (-15,11) radius 2

kodGreya [7K]

Answer:

$(x+15)^2+(y-11)^2=4$

Step-by-step explanation:

The question is

How do you write an equation for a circle with center (-15,11) and radius 2?

we know that

The equation of a circle in center radius form is given by

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

where

(h,k) is the center of the circle

r is the radius of the circle

substitute the given vales

$(x+15)^2+(y-11)^2=2^2$

$(x+15)^2+(y-11)^2=4$

If f(5)= 3, write an ordered pair that must be on the graph of y = f(x + 1) + 2

vlabodo [156]

f(5) = 3 means (5,3) is on the graph of f.

On the new graph, y = f(x+1) + 2, what do the +1 and +2 do?

Things inside the function notation inpact the x-values, since that's where x sits.

This outside the f(x) notation impact the y-values, since those are done after you've evaluated the function.

"+1" on the inside shifts every point to the left 1 unit. (Inside changes are almost always opposite from what it looks like it would do.)

"+2" on the outside will shift every point up by 2 units.

So what do you get if you take (5,3) and shift it left 1 and up 2?
