Answer:
-2(5x-7)
Step-by-step explanation:
Factor until each factor is linear
6x - 2 = x + 13
Subtract x
5x - 2 = 13
Add 2
5x = 15, x = 3
Solution: the number is 3
Y=2x+1
x is the input, so the 2x will make it twice the input, and the +1 will make it one more, therefore y(the output) is one more than twice the input :)
Vertex: (-2,-3)
axis of symmetry: x=-2
min: (-2,-3)
max: no max because it is a parabola tht opens up
Range: y > or equal to -3
