Answer:
31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.
Step-by-step explanation:
70=2.1n+3.7
70-3.7=2.1n
66.3=2.1n
66.3/2.1=n
31.57=n
Answer:Research measures include survey questions, interview questions, or constructed situations. When constructing interviews and surveys, it is important that the questions directly relate to the research questions.

Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (4, 8)
m = 
= 
Note the line crosses the y- axis at (0, 5) ⇒ c = 5
y = x + 5 ← equation in slope- intercept form
Answer:
- parent: y = x²
- transformed: y = -3x² +4
Step-by-step explanation:
You have correctly recognized that the function is quadratic, so has parent function y = x².
__
You may notice that the function drops by 3 units when x increases or decreases by 1 unit from the vertex. That factor (-3) is the vertical scale factor in the transformed function ...
f(x) = a(x -h)² +k
where "a" is the vertical scale factor and (h, k) is the location of the vertex of the transformed function.
We note that the graphed function has its vertex at (h, k) = (0, 4), so the complete transformed function with a=-3, h=0, k=4 is ...
f(x) = -3x² +4
