9. If a person bikes 0.24 miles in 1 minute, how far can they bike in 45 minutes?
10. A test car went 64 miles on 2 gallons in the morning, 16 miles on ½ gallon at noon, and 32 miles on 1 gallon at 5 pm. Is the relationship a proportional relationship?
please answer properly and show or tell me all your work
Answer:
9. 10.8 miles
10. Yes
Step-by-step explanation:
To solve number 9 I multipled 0.24 x 45 to find the distance the biker can bike in 45 minutes.
Number 10 is yes because the numbers continue proportionaly. If you work it out, you can see that each half gallon takes the car 16 miles. The distances went 16 miles for 1/2 gallon, 32 miles for 1 gallon, would go 48 miles for 1 1/2 gallons, and went 64 miles for 2 gallons.
Hope it helps!

Given:
The graph of a quadratic function [tex]y=x^2-4x+3[/tex].
To find:
(a) The coordinates of the turning point.
(b) The roots of the equation [tex]y=x^2-4x+3[/tex]
Solution:
(a)
From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.
The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.
Therefore, the coordinates of the turning point are (2,-1).
(b)
The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.
From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.
Therefore, the roots of the given equation are 1 and 3.

4r + 10 = -26
What is the answer
Answer:
r = - 9
Step-by-step explanation:
Given
4r + 10 = - 26 ( subtract 10 from both sides )
4r = - 36 ( divide both sides by 4 )
r = - 9
Need help with question 2please due in 10mins
Answer:
x 1 2 6 12 25
f(x) 22 34 82 154 310
f(3)= 46 means that in the third month, the online magazine provider will charge a total of $46.00
Step-by-step explanation:
For finding the missing f(x) values:
Plug in the x-values that are given into the original equation: f(x)= 12x + 10
ex: f(1)= 12(1) + 10 => 22
For finding the missing x value, set the original equation to the given f(x) value
ex: 34 = 12x + 10 => 2

All of the following could be rewritten as an addition problem of two integers with the same sign except _____.
-9 - (-12)
-9 - 12
-12 - 9
12 - (-9)
Answer:
Answer is - 9 + 12 because they have different signs in front of each integer. (if that is what the question means)
Step-by-step explanation:
Negative sign x negative sign = positive sign
-9 - (-12) = -9 + 12
-9 - 12
-12 - 9 = -9 - 12
12 - (-9) = 12 + 9 = 9 + 12
Complete the sentence by using always sometimes or never a parallelogram is a trapezoid
Answer:
Parallelogram is never a trapezoid
Step-by-step explanation:
Given
Shapes: Parallelogram and Trapezoid
Required
Compare both shapes
The properties for comparison of both shapes are:
In a parallelogram: It has 4 sides and opposite sides are parallel.
In a trapezoid: It has 4 sides, 2 of which are parallel while the other two are not.
Hence, the word that completes the sentence is never.

Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?
A 2
B 6
C 8
D 10
Answer:
6 miles.
Step-by-step explanation:
To solve this problem, lets make an equation in slope-intercept form (y = mx + b)
The initial fee is $6. This is our y-intercept (b) as it is unchanging.
Our slope (m) would be $3, as it changes value per mile, which will be represented by x.
$24 was the total fare, so this is our y.
We have:
24 = 3x + 6
Subtract 6 from both sides.
24 - 6 = 3x + 6 - 6
We get:
18 = 3x
Divide by 3 on both sides.
18/3 = 3x/3
We get:
6 = x
So, Mike traveled 6 miles.

Sports of the 25 baseball players on the baltimore orioles 2005 roster, 17 threw right handed, 12 were over 30 years old, and 9 both threw right handed and were over 30 years old. How many players on the team neither threw right handed nor were over 30 years old?
Answer: 5
Step-by-step explanation:
Let R be the event that players threw right-handed.
Let O be the event that players were over 30 years old.
Given: Total players = 25
n(R) = 17 , n(O) = 12 , n(R and O)=9
According to the probability formula,
n(R or O) = n(R)+n(O)-n(R and O)
⇒ n(R or O) =17+12-9
⇒ n(R or O) = 20
Now , n(neither R nor O) = Total - n(R or O)
= 25-20
=5
Hence, the number of players on the team neither threw right-handed nor were over 30 years old = 5
