Bicyclists in a 10-mile race were surveyed about their finishing times in minutes (f) and the number of previous races they had

competed in (n). There was a negative linear relationship between f and n that is best modeled by the equation f=−0.45n+43.6 .
Which statement is true?


The model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 43.6 minutes.

The model predicts that the average finishing time for a race is 43.6 minutes

The model predicts that for each additional race a bicyclist has competed in, the finishing time decreases by about 0.45 minutes.

The model predicts that the finishing time for a bicyclist who has competed in 43.6 previous races is about 0.45 minutes less than his finishing time in his first race.

what is the equation in slope form of the line that is parallel to the given line and passes through the point (-3,1)​
viktelen [127]

Answer:

D

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate the slope of the given line using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 4) and (x₂, y₂ ) = (2, 2) ← 2 points on the line

m = \frac{2+4}{2+2} = \frac{6}{4} = \frac{3}{2}

Parallel lines have equal slopes and using (a, b) = (- 3, 1), then

y - 1 = \frac{3}{2}(x - (- 3)), that is

y - 1 = \frac{3}{2}(x + 3) ← in point- slope form

What is the simplest form of the expression 6x(x − 4) − 16x2 − (9x − 1)
Sedbober [7]
Use distributie property which is
a(b+c)=ab+ac
therefor
6x(x-4)=6x^2-24x

distribute the negative 1 infroont of the (9x-1)
-1(9x-1)=-9x+1
now we have

6x^2-24x-16x^2-9x+1
gropu like terms
6x^2-16x^2-24x-9x+1
add like terms
-10x^2-33x+1 is simplest form

On a number line, what is the distance between -29 and 100? A) 29 B) 71 C) 81 D) 129
shusha [124]

-29 is 29 bars away from 0. 100 is 100 bars away from 0.

29 + 100 = 129

So the distance between -29 and 100 is 129. The answer is D.
