First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
Answer:
Parent Function: y = x^2
Vertex: (1,3)
Axis of Symmetry: x = 1
Y-Intercept(s): (0,1)
X-Intercept(s): (1−√62,0),(1+√62,0)
Step-by-step explanation:
hope this helps! =)
Answer:

Step-by-step explanation:

Distribute.

Add 5x and subtract 15 on both sides.


Multiply -1 on both sides.

Answer:
False
Step-by-step explanation:
1+16=17
14+2=16
17 does not = 16
