What is the general equation of a straight line ?

The general equation of a straight line is given by -

y = mx + c

where -

m → slope of line.

c → y - intercept of line.

According to the question -

The y - intercept of the line is at the coordinates (0, 40). Now, we have to find the slope of this line. Consider the two coordinates -

A(0, 40) and B(10, 60)

Slope of a straight line is given by -

m = y₂ -y₁ / x₂ - x₁

m = 60 - 40 / 10 - 0

m = 20 / 10

m = 2

Now, substituting the values in the general equation of line, we get -

y = 2x + 40

Hence, Option By = 2x + 40 is the correct alternative.

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.

Hence option a)2√74 ft is the correct answer.

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.

Answers

Answer:

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.

Therefore, the roots of the given function are: x = 1, x = 3

-9x+10y=25 7x-4y=7 Elimination method (with work)

Answers

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.

The solution of the geometric system is (x, AB, BC, AC) = (10, 14, 19, 33).

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)

4 · x - 7 = 3 · x + 3

x = 10

AB = 10 + 4

AB = 14

BC = 2 · 10 - 1

BC = 20 - 1

BC = 19

AC = 4 · 10 - 7

Answers

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

y = 259/0.37

y = 700.
