Answer:
5.7% decrease
Step-by-step explanation:
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!

y=-1/2x(x-8)
Show steps to put in vertex form
Answer:
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0
Step-by-step explanation:
y = -1/2x(x-8) (distributive property of equality)
y = -1/2x^2 + 4x + 0
Vertex form : y = ax2 + bx + c
There is no C so you can also represent that by putting a zero so,
y = -1/2x^2 +4x + 0,
Which is the same as,
y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0

A biker can travel 8 miles in one hour. How long will it take him to travel 32 miles?
Create a table. Highlight the unit rate. State your answer clearly with a label.
Answer:
4hrs
Step-by-step explanation:
Given parameters:
Rate of the biker = 8mph
Unknown:
Time taken to travel 32miles = ?
Solution:
We have been given the speed of the bike which is 8mp.
Speed is the distance covered per unit of time. It is mathematically expressed as;
Speed = [tex]\frac{distance}{time}[/tex]
So,
Time = [tex]\frac{distance }{speed }[/tex]
Now, insert the parameters and solve;
time = [tex]\frac{32}{8}[/tex] = 4hrs

The evaluated value of the given function is -
│-9│+ │11│ - │-15│ + │-6│= 11.
What is function? What is modulus function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
We can define the modulus function as -
|x| = - x {x < 0}
|x| = x {x > 0}
Given is to evaluate the expression -
│-9│+ │11│ - │-15│ + │-6│
We can evaluate the function as -
│-9│+ │11│ - │-15│ + │-6│
9 + 11 - 15 + 6
20 - 9
11
So, we can write -
│-9│+ │11│ - │-15│ + │-6│= 11
Therefore, the evaluated value of the given function is -
│-9│+ │11│ - │-15│ + │-6│= 11.

What is the rate of change of the following equation?
y=x-5
Step-by-step explanation:
rate of change =y/x
= _5
rate of change = 1
What is rate of change?Rate of Change: The speed at which a variable changes over a specific period of time. It is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, this ratio is represented by the slope of a line.
Given equation:
y = x - 5
rate of change = m = ?
Comparing the equation with slope intercept form of line
y = mx + c
slope m = 1
c = -5
Hence the rate of change (slope m) = 1

A -19/2
B 19/2
C 2/19
D -2/19
Answer:
a) -19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x + 18 + 6x + 9 = 7x + 8
3x + 6x - 7x = 8 - 18 - 9
2x = -19
2x/2 = -19/2
Therefore, x = -19/2
Divide using synthetic division, and write a summary statement in fraction form
2x^3+3x^2+4x-10/x + 1
Using synthetic division, a summary statement in fraction form of the polynomial division is; 2x² + x + 3 - (13/(x + 1))
How to use Synthetic Division?
We are given the polynomial fraction as;
(2x³ + 3x² + 4x - 10)/(x + 1)
This means that we want to divide the polynomial (2x³ + 3x² + 4x - 10) by (x + 1) using synthetic division.
For the divisor, we have x + 1, and that means x + 1 = 0, x = -1
So, we'll be using -1 for the synthetic division and we have;
-1 | 2 3 4 -10
× -2 -1 -3
-------------------------
2 1 3 -13
Now we will form the expression in the form of fraction again
2x² + 1.(x) + 3 - 13/(x + 1)
