Answer:
Step-by-step explanation:
Given the equations
solving the system of the equation by elimination method
solve 45y=5 for y:
solve for x:
Add 36 to both sides
A graphing calculator shows two solutions:
(x, y) =
(-2, 0) or (-1, -10)
Vertex of f(x)=x^2-x+2 is:
(0.5,1.75)
Hey there!
Notice in the image, <em>I</em> is in between Q and C and QC is made up of QI and IC.
Knowing this, you can conclude that QI+IC=QC
Since you know that QI=3x-13 and IC=2x-12, you can add these two expressions together to get QC:
(3x-13)+(2x-12)
5x-25
Therefore, QC is 5x-25.
