HELP PLEASE!!!!!!!! The graph shows the functions f(x), p(x), and g(x): Graph of function g of x is y is equal to 2 multiplied by 0.85 to the power of x. The straight line f of x joins ordered pairs minus 7, 3 and minus 3, minus 2 and is extended on both sides. The straight line p of x joins the ordered pairs 4, 1 and minus 3, minus 2 and is extended on both sides. Part A: What is the solution to the pair of equations represented by p(x) and f(x)? (3 points) Part B: Write any two solutions for f(x). (3 points) Part C: What is the solution to the equation p(x) = g(x)? Justify your answer. (4 points)

Post a screenshot, too tired to try to read that. Pic don't work. Use lightshot, or Snipping Tool (if you're on a windows comp)

OpenStudy (eriyalovesu):

will that work

OpenStudy (eriyalovesu):

is part a (-3,-2)

OpenStudy (agent0smith):

Part A: What is the solution to the pair of equations represented by p(x) and f(x)? Yes, (-3, -2) is where they intersect

OpenStudy (eriyalovesu):

yeah! okay now part b is asking for solutions which is where they intersect with the axis's right? if so wouldn't we have to write an equation for it?

OpenStudy (agent0smith):

B is asking for any two points that are on the line. Just pick two points.

OpenStudy (eriyalovesu):

kk and for part c?

OpenStudy (agent0smith):

Find where they intersect, but they only want the x-coordinate, not the y.

OpenStudy (eriyalovesu):

how do I do that?

OpenStudy (agent0smith):

The same way you did part A.

OpenStudy (eriyalovesu):

at 1,4 but that is the y- coordinate

OpenStudy (agent0smith):

What is the x-coordinate where the two lines touch?

OpenStudy (eriyalovesu):

idk

OpenStudy (agent0smith):

Find where the two lines intersect. You know how to do that.

OpenStudy (eriyalovesu):

the graph cuts off before they do unless its (1,4)

OpenStudy (agent0smith):

Points are always (x, y) not (y, x)

OpenStudy (eriyalovesu):

okay! knew that just had a blonde moment lol so its (4,1)

OpenStudy (agent0smith):

But p(x) = g(x) means they only want the x-value

OpenStudy (eriyalovesu):

so 4

OpenStudy (agent0smith):

Yep, good job :)

OpenStudy (eriyalovesu):

can you help me with one more problem?

OpenStudy (agent0smith):

okay

OpenStudy (eriyalovesu):

The coordinate plane below represents a city. Points A through F are schools in the city. graph of coordinate plane. Point A is at negative 3, negative 4. Point B is at negative 4, 3. Point C is at 2, 2. Point D is at 1, negative 2. Point E is at 5, negative 4. Point F is at 3, 4. Part A: Using the graph above, create a system of inequalities that only contain points C and F in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points) Part B: Explain how to verify that the points C and F are solutions to the system of inequalities created in Part A. (3 points) Part C: Natalie can only attend a school in her designated zone. Natalie's zone is defined by y < −2x + 2. Explain how you can identify the schools that Natalie is allowed to attend. (2 points)
