Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3

mariana wants to put 6 3/4 feet of border across the top of a wall she has 3 6/7 feet of border. what fraction of the project can she complete
Answer:
[tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Length of the border Mariana wants to put across the top of a wall = [tex]6\frac{3}{4}[/tex] feet
= [tex]\frac{27}{4}[/tex] feet
If she has the length of the border = [tex]3\frac{6}{7}[/tex] feet
= [tex]\frac{27}{7}[/tex] feet
Therefore, fraction of the project can be completed = [tex]\frac{\frac{27}{7}}{\frac{27}{4} }[/tex]
= [tex]\frac{27}{7}\times \frac{4}{27}[/tex]
= [tex]\frac{4}{7}[/tex]
Fraction of the project can be completed = [tex]\frac{4}{7}[/tex]

Find the slope of the line with the following points:
(9,3) & (-2,6)
Answer:
m=-0.2727272727
Step-by-step explanation:
Use the formula m=(y *2 - y *1) / (x *2 - x *1)
So it will be (6-3) / ((-2)-9)
Which results in 3/-11 = -0.272727272727272

Giving a test to a group of students, the grades and gender are summarized below A B C Total Male 10 17 6 33 Female 11 15 13 39 Total 21 32 19 72 If one student is chosen at random, Find the probability that the student was male AND got a "C". Submit Question Question 14
Answer:
1 / 12
Step-by-step explanation:
Given the following data:
_______A___ B ___C ___Total
Male__ 10 __ 17 ___6___ 33
Female_ 11__ 15___ 13___ 39
Total___21__ 32__ 19___ 72
Find the probability that the student was male AND got a "C"
Number of males who got C = 6
Total number of student students = 72
P(student was male and got C) = (number of males who got C / total number of students)
= 6 / 72
= 1 / 12
The function y = 3.75 +1.5(x - 1) can be used to determine the cost in dollars for a taxi ride
of x miles. What is the rate of change of the cost in dollars with respect to the number of
miles?
Answer:
$1.50 per mile
Step-by-step explanation:
y = 3.75 + 1.5(x - 1)
~Simplify left side
y = 3.75 + 1.5x - 1.5
~Combine like terms
y = 2.25 + 1.5x
As we can see, this question is written in slope-intercept form [ y = mx + b ] where m = slope and b = y-intercept.
1.5x resembles the slope (cost of how many miles you ride in the taxi)
2.25 resembles the y-intercept. We can just assume this is the "fee or tip" amount since the question doesn't state what this actually is.
Since 1.5 is the slope, this is the rate of change.
Best of Luck!
The rate of change of cost with respect to the number of miles is 1.5 dollars per mile.
Given information:
The function [tex]y = 3.75 +1.5(x - 1)[/tex] can be used to determine the cost in dollars for a taxi ride of x miles.
It is required to calculate the rate of change of cost with respect to the distance traveled.
The rate of change of cost can be measured as,
[tex]y = 3.75 +1.5(x - 1)\\y = 3.75 +1.5x - 1.5\\\dfrac{dy}{dx}=0+1.5-0\\\dfrac{dy}{dx}=1.5[/tex]
Therefore, the rate of change of cost with respect to the number of miles is 1.5 dollars per mile.

Write an equation of the line passing through the point (4,3) that is perpendicular to the line 4x-7x=9
Answer:
The equation 4x-7x=9 simplifies into x=-3, which is a horizontal line. A perpendicular line would be vertical, and the equation for vertical lines is y=b, b being a constant. In this case on the point (4,3), y is 3, so the equation of the line is y=3.

x^3 + 3 = 57
Answer:
x=3*2 1/3
Step-by-step explanation:
In order to solve this non-linear equation, we need to move all the terms to the left side.
In our example,
- term 3, will be moved to the right side.
Notice that a term changes sign when it 'moves' from one side of the equation to the other.
(x^3 + 3) + (-3) = 57 + (-3)
We need to get rid of expression parentheses.
If there is a negative sign in front of it, each term within the expression changes sign.
Otherwise, the expression remains unchanged.
In our example, there are no negative expressions.
x^3 + 3 - 3 = 57 - 3

He Hernández family is going to a swim meet. They bought 2 cases of water for $3.98 each, 3 bags of ice for $1.99 each, and a bag of oranges for $8.89. Before they leave, they filled up the car with 38.63 liters of gasoline at a cost of $0.655 per liter. What is the total cost for everything before tax?
Total cost of water, w =$ 3.98×2 = $7.96 .
Total cost of ice, i = $ 1.99×3 = $5.97 .
Total cost of orange, o = $8.89 .
Total cost of gasoline , g = $38.63×0.655 = $25.30 .
Now, total cost is the summation of every cost mention above :
T = $ ( 7.96 + 5.97 + 8.89 + 25.30 )
T = $48.12 .
Therefore, total cost for everything before tax is $48.12 .
Hence, this is the required solution.
Amy reached into a bag, recorded the color of the tile she picked, returned the tile and drew again. These are the tiles she has drawn so far: red, red, blue, yellow, blue, red, green, red, blue, green Based on this data, a. What is the probability that her next draw will be red? 40 b. What is the probability that her next draw will NOT be blue? c. If she draws 70 more times, how many times would you expect a green?
Answer:
A) 0.7
B) 0.2
C) 14 times
Step-by-step explanation:
We are told that the tiles she has drawn so far are;
red, red, blue, yellow, blue, red, green, red, blue, green.
In this, we have 10 number.
So for the first 10 number of tiles, she had:
4 red tiles
3 blue tiles
1 yellow tile
2 green tiles
A) probability that her next draw will be red = number of red tiles/total number of initial tiles drawn = 4/10 = 0.4
B) probability that her next draw will NOT be blue = number of tiles that are not blue/total number of initial tiles drawn = 7/10 = 0.7
C) Probability that the next draw will be green = number of tiles that are green/total number of initial tiles drawn = 2/10 = 0.2
Now, if she draws 70 more times, number of times she will expect a gree tile = 0.2 × 70 = 14 times
