Answer:
y = 3x + 6
Step-by-step explanation:
The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.
<h3>y = 2x + 4</h3>
when x = -3, y = 2(-3) + 4 = -6 + 4 = -2
when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0
when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2
when x = -0, y = 2(0) + 4 = 0 + 4 = 4
<h3>y = 3x + 6</h3>
when x = -3, y = 3(-3) + 6 = -9 + 6 = -3
when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0
when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3
when x = -0, y = 3(0) + 6 = 0 + 6 = 6
The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)
This is same as the results from the function y = 3x + 6
Answer:
see below
Step-by-step explanation:
2+7 = 9
9+7 = 16
16+7 = 23
We are adding 7 each time
an = a1+ 7(n-1) where an is the nth term a1 is the first term and n is the term number
an = 2 + 7n - 7
an = 7n -5
or
an+1 = an +7
The scatter plot showing data gathered and line of best fit is attached below :
Answer:
69
Step-by-step explanation:
Given the regression model :
y = 1.73x + 0.0924
Where,
y = number of pink flowers
x = Red flowers
Slope = 1.73
Intercept = 0.0924
The number of pink flower that are predicted to bloom on a shrub of 40 red flowers :
Put x = 40 and calculate the value of y
y = 1.73(40) + 0.0924
y = 69.2 + 0.0924
y = 69.2924
Number of pink flowers = 69
