Tell whether the function y = 5x − 2 is linear.
Answer:
Step-by-step explanation:
Yes, it is a linear equation
Answer:
Yes, it is Linear
Step-by-step explanation:
This is the answer because A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

9. A water pail in your backyard has a small hole in it. You notice that it has drained a total of 3.5 liters in 4 days. What is the average change in water volume each day?
10. The price of one share of ABC Company declined a total of $45.75 in 5 days. What was the average change in the price of one share per day?
11. To avoid a storm, a passenger-jet pilot descended 0.44 miles in 0.8 minutes. What was the plane’s average change of altitude per minute?
Answer: 9-11 below
Step-by-step explanation:
9. Well, we're given that the hole drains color(red)(3.5color(white)(l)"L" in color(green)(4color(white)(l)"d", so we can write the rate as
(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d"))
Now we perform this division, and afterward the denominator will be 1 and thus it will tell us the number of liters drained per day:
(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" ")|)
Therefore, color(blue)(0.875color(white)(l)"liters" are drained every day on average.
10. $
9.25
decrease per day
Explanation:
We can divide the total price decrease by the number of days it took to reach that decrease to find the average decrease per day:
$
45.75

9.25
decrease per day
11. The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute

Which expression is equivalent to: (x +9)(x+3)
a. x2 + 6x + 6
b. x2+27x+12
c. x2+ 12x+27
d. x2+ 12x + 12
Answer:
c
Step-by-step explanation:
x*x=x^2
x*9=9x
x*3=3x
9x+3x=12x
9x3=27
x^2+12x+27
Answer:
C
Step-by-step explanation:
To solve use the FOIL method, First, Outside, Inside, Last. This means to multiply the first terms, the ones on the outsides, the ones on the insides, and finally the last ones.
First, multiply x*x= [tex]x^{2}[/tex]
Then, multiply x*3= 3x
Next, multiply 9*x= 9x
Finally, multiply 9*3= 27
To simplify put all of the products together, [tex]x^{2}[/tex]+3x+9x+27, then add like terms [tex]x^{2}[/tex]+12x+27, so the answer is C.

Factor and find the zeros k^2+7k+12
Answer:
(k+3)(k+4)
The zeros are -3 and -4
Step-by-step explanation:
k2+7k+12
The middle number is 7 and the last number is 12.
This means we need two numbers that:
Add together to get 7
Multiply together to get 12
to fit in this equation (k+_)(k+_)
in this equation, it would be 3 and 4
3+4 = 7
3*4 = 12
Now we fill in the blanks to get
(k+3)(k+4)
To get the zeros, use the equations
k+3=0 and k+4=0
You end up with
k=-3 and k=-4

John is stuck downtown Atlanta and has used is cell phone to order an Uber. The pick up fee is $20 with an additional charge of 0.25 cents per mile driven. Which equation below could be used to find out the total cost for a 30 mile trip? What is the total cost of the 30 mile trip?

Step-by-step explanation:
Given that :
Cost of Uber :
Pick up fee = $25
Additional charge = 0.25 cent per mile driven
Cost of 30 mile trip :
Pickup fee + (additional charge * number of miles)
$25 + (0.25 * 30)
25 + 7.5
= $32.5

Answer:
x= -p+q+y
Step-by-step explanation:
-x on each side
y-x=p-q
-y on each side
-x=p-q-y
÷everything on both sides by ‐1
We have to divide by -1 because x can't be negative
x = -p+q+y

Use your answer from part 1 to solve the following problem.
A scale drawing of a rectangular park is 5 inches wide and 7 inches long. The actual park is 250 yards long. What is the area of the actual park?
someone please anwser ASAP its due today
Answer:
Part 1
If the actual park is 250 yards LONG, I think it means that its LENGTH is also 250 yards
Part 2
It's a proportion:
5=x
7=250
5*250:7=178.6 yards
The area is 178.6 yards wide and 250 yards long
