Answer:
Just factorize the given plynomials.
Step-by-step explanation:
like in first example 7x+49
7(x+7)
Slope of f(x)
Slope of g(x)
PART A)
The slopes of f(x) and g(x) are the same.
PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b
y = 4x - 1
The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.
90 + 20x + 10x = 180
30x = 90
x = 3
So 5 pounds=12.5
divide 12.5 by 5 to get dollars per pound
$2.5 per pouind
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
