X - (-2) = 21 <== ur equation
x + 2 = 21
x = 21 - 2
x = 19
Answer:
The slope of the graph is 5, and the y-intercept is (0, -3).
Step-by-step explanation:
Let's start by finding the y-intercept.
The y-intercept is the point where the line intercepts the y-axis.
Looking at the graph, we can determine that the y-intercept is (0, -3).
The slope of a graph can be found using two points on the line.
Let's use (0, -3) and (1, 2):

Therefore the slope of the graph is 5, and the y-intercept is (0, -3).
5x^2 + 7
the coefficient is 5
the variable is x

Answer:
x = 4/5
y = 1/2
Step-by-step explanation:
Answer:
The next three terms are 54, 162, 486
Step-by-step explanation:
Exponential sequences you multiply to find the next term
6 x 3 = 18 (to find the next term you can multiply the previous term by 3)
18 x 3 = 54
54 x 3 = 162
162 x 3 = 486
