The product of two consecutive off integers is equal to 27 plus six times the sum of the integers . What is the largest integer?
Answer:
15
Step-by-step explanation:
x(x + 2) = 27 + 6(x + x + 2)
x^2 + 2x = 27 + 6(2x + 2)
x^2 + 2x = 27 + 12x + 12
x^2 + 2x - 12x - 12 - 27 = 0
x^2 -10x - 39 = 0
(x + 3)(x - 13) = 0
x + 3 = 0
x = -3 (extraneous solution)
x - 13 = 0
x = 13
x + 2 = 15

The in the canoe race, Dallas paddles faster than Mason.
According to the statement
We have to find that the Speed of the .
So, For this purpose, we know that the
The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.
From the given information:
Mason and Dallas are in a canoe race. Mason paddles 7/8 mile in 1/4. Dallas paddles 9/5 miles in 1/3 hour.
Then
The Mason paddles 7/8 mile in 1/4 hour.
We calculate the Speed = Distance/Time
Speed = (7/8)/(1/4)
Speed = (7/8) × (4/1)
Speed = 7/2
Speed = 3.5 miles per hour
And Dallas paddles 9/5 miles in 1/3 hour.
Speed = Distance/Time
Speed = (9/5)/(1/3)
Speed = (9/5) × (3/1)
Speed = 27/5
Speed = 5.4 miles per hour.

-9x+10y=25 7x-4y=7 Elimination method (with work)
Values of x and y in the given equations by elimination method are 5 and 7 respectively. that is, x=5 and y=7.
In the elimination method, the aim is to entirely remove one of the unknown variable which would eventually make it easier to calculate be other unknown. However, it is important to note that this method is most effective when neither of the coefficients is equal to 1. The coefficient of either of the two variables will be made the same in both equations and by subtracting one from the other, it would be eliminated. It is a non-graphical methods of solving simultaneous linear equations.
consider the equations as (1) and (2),
-9x+10y=25..........................(1)
7x-4y=7............................(2)
Now, multiply equation (1) by 4 and equation (2) by 10
Let the equations we get now be (3) and (4),
-36+40y=100......................(3)
70x-40y=70........................(4)
We can see that the coefficient of y in both equations is same that is 40
Now, add equation (3) and (4)
-36+40y+70x-40y=100+70 ( y terms cancel out)
By evaluating we get,
-34x=170
x=-170/34
x=5
To find the value of y, substitute value of x in equation (2)
7x-4y=7
7*5-4y=7
35-4y=7
35-7=4y
28=4y
y=28/4
y=7
Therefore, we can conclude that the values of x and y in the given equations -9x+10y=25 and 7x-4y=7 by elimination method are 5 and 7 respectively. that is, x=5 and y=7.

Solution A is 20% alcohol and Solution B is 17% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 179 milliliters of
pure alcohol?
Using a system of equations, it is found that she uses 700 ml of Solution B.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
Variable x: Number of ml of Solution A.Variable y: Number of ml of Solution B.She uses 400 milliliters less of Solution A than Solution B, hence:
x = y - 400.
Solution A is 20% alcohol and Solution B is 17% alcohol. The esulting mixture has 179 milliliters of pure alcohol, hence:
0.2x + 0.17y = 179.
Since x = y - 400, we have that:
0.2(y - 400) + 0.17y = 179.
0.37y = 259

x = 1, x = 3
Step-by-step explanation:
Given function:
[tex]f(x)=\left(\log(3x)-2 \log(3)\right) \cdot \left(x^2-1\right)[/tex]
The roots of the function are when f(x) = 0:
[tex]\begin{aligned}f(x) & = 0\\ \implies \left(\log(3x)-2 \log(3)\right) \cdot \left(x^2-1\right) & = 0\\\\ \textsf{Therefore,} \:\:\:\log(3x)-2 \log(3) & = 0\\ \textsf{and }\:\:\:x^2-1 & = 0 \end{aligned}[/tex]
Case 1
[tex]\begin{aligned}\left(\log(3x)-2 \log(3)\right) & = 0\\\log(3x) & = 2 \log(3)\\ \log(3x) & = \log (3)^2\\ \log(3x) & = \log (9)\\ 3x & = 9\\ x & = 3\end{aligned}[/tex]
Case 2
[tex]\begin{aligned}\left x^2-1\right & = 0\\x^2 & = 1\\ x & = \pm 1\end{aligned}[/tex]
As logs of negative numbers cannot be taken, x = 1 only.

Find the length of the missing side. Leave your answer in simplest radical form.
Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.
Hence option a)2√74 ft is the correct answer.
What is the length of the missing side?The Pythagoras theorem can be expressed as;
c = √( a² + b² )
Where c is hypotenuse, a and b are the other two sides of the right triangle.
Given the data in the image;
Length leg 1 of the right triangle a = 14ftLength leg 2 of the right triangle b = 10ftLength of hypotenuse c = ?Plug the given values into the above equation and solve for the hypotenuse 'c'.
c = √( a² + b² )
c = √( (14)² + (10)² )
c = √( 196 + 100 )
c = √( 296 )
296 can be written as 4 × 74, and 4 can further be written as 2²
Hence
c = √( 2² × 74 )
c = 2√74 ft
Given the length of the perpendicular height and base length, the hypotenuse of the right triangle is 2√74 ft.

What are the values of a variable and the lengths of three line segments associated to it?
In accordance with geometry, three points are collinear if and only if these points lie on the same line. Then, the geometric system is represented by the following model:
AC = AB + BC
If we know that AB = x + 4, BC = 2 · x - 1 and AC = 4 · x - 7, then the value of x and the lengths of the line segments are, respectively:
4 · x - 7 = (x + 4) + (2 · x - 1)

(a) Choice C is correct

(c) x =11 Point is at (11,2)
(d) Domain of f is x is [tex]\:x < 2\quad \mathrm{or}\quad \:x > 2\:[/tex]
In interval notation [tex]\:\left(-\infty \:,\:2\right)\cup \left(2,\:\infty \:\right)[/tex]
(e) x intercept is at x = -7
(f) y-intercept is at [tex]-\frac{7}{2} = -3.5[/tex]
Step-by-step explanation:
(b) Plug in x = 1 into the equation [tex]\:\:\frac{x+7}{x-2} = \frac{1+7}{1-2} = \frac{8}{-1} = -8[/tex]
(c) If f(x) = 2 then we get [tex]2 = \:\:\frac{x+7}{x-2}[/tex]
==> 2(x-2) = x + 7
==> 2x - 4 = x + 7
==> 2x - x = 7 +4 =11
==> x = 11
(d) Domain of f is all values of x -∞ < x < ∞ except at x = 2 since at x = 2 the denominator is 0 and division by zero is undefined; So we can say the domain is x < 2 or x >2
(e) To get the x-intercept set y = 0 and solve for x
We get (x+7)/(x-2) = 0
x+7 = (x-2)(0) = 0
x = -7 and the x intercept is at point (-7, 0)

The quart is an English volume unit equivalent to one-quarter gallon. There are now three types of quarts in use: the liquid quart and dry quart of the US customary system, as well as the imperial quart of the British imperial system. All of them are essentially equivalent to one liter. It is split into two pints or four cups (in the United States). The exact size of the quart has historically fluctuated with the varying values of gallons over time and in relation to different commodities.
