[tex]\begin{array}{| c | c | c |c| c| c | c| c |}
\cline{1-8} x & - 3 & - 2 & - 1 & 0& 1 & 2 & 3\\
\cline{1-8} y & 6 &\textbf{0} &\textbf{ - 4} & - 6 & \textbf{ - 6}& \textbf{ - 4}& \textbf{0} \\
\cline{1-8}
\end{array}[/tex]
Step-by-step explanation:
The 2nd column of the table means that when x= -3, y= 6.
Since this table of values is for the equation of y= x² -x -6,
substitute the given values of x into the equation to find the respective values of y.
3rd column:
y= x² -x -6
When x= -2,
y= (-2)² -(-2) -6
y= 4 +2 -6
y= 0
4th column:
y= x² -x -6
When x= -1,
y= (-1)² -(-1) -6
y= 1 +1 -6
y= -4
6th column:
y= x² -x -6
When x= 1,
y= 1² -1 -6
y= 1 -1 -6
y= -6
7th column:
y= x² -x -6
y= 2² -2 -6
y= 4 -2 -6
y= -4
8th column:
y= x² -x -6
y= 3² -3 -6
y= 9 -3 -6
y= 0

Domain: (-∞, ∞)
Range: (-∞,1]
Answer:
Domain = All Real Numbers
Range = y≤1
Step-by-step explanation:
Since parabolas are continuous, the domain is all real numbers. The range, or y value, is all real numbers less than or equal to 1 (y≤1), since 1 is the vertex.

Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at the start of the trip and asking to join, but they brought no food. By what percent would the time for the trip shorten for the trip if everyone ate their normal portions?
Answers
The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%

A.5 × 10-7
B.5 × 10-1
C.5 × 10-10
D.5 × 107
Answers
Answer:
1.32 * 10^2
Step-by-step explanation:
Given the expression;
(5×10−3)+(6×10−3)2.2×10^4
First we need to do the multiplication first;
= (5×10−3)+(13.2×10−3+4)
= (5×10−3)+(13.2×10^1)
= 0.005 + 132
= 132.005
= 1.32 * 10^2
Hence the equivalent expression is 1.32.0 * 10^2

Find the probability that a randomly selected customer will have to wait a) less than 25 minutes b) more than 38 minutes c) between 26 and 32 minutes
Answers
Answer:
a) 0.30854
b) 0.21186
c) 0.23468
Step-by-step explanation:
Mario's Pizza delivers pizzas within a 10-mile radius of the restaurant. Their delivery times are Normally distributed with a mean delivery time of 30 minutes and a standard deviation of 10 minutes.
We solve using z score formula.
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
Find the probability that a randomly selected customer will have to wait
a) less than 25 minutes
for x < 25 minutes
z = 25 - 30/10
z = -0.5
Probability value from Z-Table:
P(x<25) = 0.30854
b) more than 38 minutes
For x > 38 minutes
z = 38 - 30/10
z = 0.8
Probability value from Z-Table:
P(x<38) = 0.78814
P(x>38) = 1 - P(x<38) = 0.21186
c) between 26 and 32 minutes
For x = 26 minutes
z = 26 - 30/10
z = -0.4
Probability value from Z-Table:
P(x = 26) = 0.34458
For x = 32 minutes
z = 32 - 30/10
z = 0.2
Probability value from Z-Table:
P(x = 32) = 0.57926
The probability that a randomly selected customer will have to wait between 26 and 32 minutes is calculated as:
P(x = 32) - P(x = 26)
= 0.57926 - 0.34458
= 0.23468

Step-by-step explanation:
Answer:
No, the answer is a solution to the inequality.
Step-by-step explanation:
When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the inequality.
2x > 5; x = -4
2(-4) > 5
-8 < 5
The answer is false, because there is no solution to -8 < 5. Therefore, the value is not a solution of the inequality.

Answers
Answer:
Step-by-step explanation:
C=0.14×7,200=1008
Nadia made a total of $1008 last week in commission sales
b). To express the total amount she made in 2011, we derive the formula below;
Total amount (2011)=Average weekly commission× number of weeks in 2011
where;
Average weekly commission=$1008
number of weeks in 2011=52
replacing;
Total amount (2011)=(1008×52)=52,416
The total amount Nadia in commission in 2011=$52,416

Linear equations
Answers
Answer:
- So were x is 0 that is your y-intercept.
y-intercept: 5
- For your slope it is alway Rise over Run and if your slope is negative you might go down instead of up. So for this table your slope is a zero slope because it is going directly across the graph horizontally. Think of it as a stick figure, with a positive slope they walk up the line with a negative they walk down and zero they walk strait on flat ground. so therefore there is no slope.
You always have your y-intercept in you equation
y=mx+b mx is slope and b is your y-intercept
since your line is not negative or positive and is horizontal a zero slope meaning there is like no slant or angle to your line your equation will look like this.
y=5
because there is no mx (slope) and only a y-intercept
slope: 0
y-intercept: 5
Equation: y=5
