-67 = d + -18 Add 18 to both sides
-49 = d Switch the sides to make it easier to read
d = -49
Answer:
its actually a geometric because there is exponential growth. if it was arithmetic there would be a linear line as the quantities would be proportional (growing at a particular rate/at equal intervals) and if it was arithmetic it wouldn't curve
<span> x^2+8x+12 = </span>(x + 6)(x + 2)
Answer:
k = ⅕
Step-by-step explanation:
The slope-intercept equation for a straight line is
y = mx + b, where
m = the slope and
b = the y-intercept
Data:
(3,4) = a point on the line
(3k,0) = x-intercept
(0,-5k) = y-intercept
Calculations:
1. Slope
m = (y₂ - y₁)/(x₂ - x₁) = (-5k - 0)/(0 - 3k) = -5/(-3) = ⁵/₃
This makes the equation
y = ⁵/₃x - 5k
2. k
Insert the value of the known point: (3,4)
4 = (⁵/₃)(3) - 5k
4 = 5 - 5k
-1 = -5k
k = ⅕
The figure below shows your graph passing through (3,4) with intercepts 3k and -5k on the x- and y-axes respectively
