-1.1. You have to add -2.5 and -3 which gives you -5.5. When you divide -5.5 over 5 that gives you -1.1.
D, because the will not intersect i believe
I think it is the first one: Different bar widths.
Step 1: Pick any two points
The points are represented as (x1,y1), (x2,y2).
where x1= -4, y1= -8, x2= 0, y2= 4
Step 2: Write out the formula of the equation to use
Step 3: Substituting the values and to get the equation
The equation that represents the graph is y= 3x+4.
Option A is the correct answer.
Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x + 7)² - 9 ← is in vertex form
with h = - 7 and k = - 9
vertex = (- 7, - 9 )
