The equation of the line is [tex]y=-\frac{3}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
The equation of a line can be written using the following form
[tex]y-y_0 = m(x-x_0)[/tex]
where
m is the slope of the line
[tex](x_0,y_0)[/tex] are the coordinates of a point lying on the line
For the line in this problem, we know that:
[tex]m=-\frac{3}{4}[/tex] is the slope
[tex](x_0,y_0)=(-5,4)[/tex] are the coordinates of the point
Therefore, substituting into the equation,
[tex]y-4=-\frac{3}{4}(x-(-5))[/tex]
And re-arranging the equation we get:
[tex]y-4=-\frac{3}{4}(x+5)\\y-4=-\frac{3}{4}x-\frac{15}{4}\\y=-\frac{3}{4}x+(4-\frac{15}{4})\\y=-\frac{3}{4}x+\frac{1}{4}[/tex]

Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. s • 5
—————————————————— = —————
L.C.M 15
R. Mult. • R. Num. 3
—————————————————— = ——
L.C.M 15

3.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
s • 5 - (3) 5s - 3
——————————— = ——————
15 15
Equation at the end of step 3 :
5s - 3
—————— = 0
15
Step 4 :
When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
5s-3
———— • 15 = 0 • 15
15
Now, on the left hand side, the 15 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
5s-3 = 0
Solving a Single Variable Equation :
4.2 Solve : 5s-3 = 0
Add 3 to both sides of the equation :
5s = 3
Divide both sides of the equation by 5:
s = 3/5 = 0.600
One solution was found :
s = 3/5 = 0.600
BTW YOu can but the answer as 0.600 or 3/5

how do you write 11% as a decimal?
Answer: 0.11
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.
So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.
Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us .11 or 0.11.
So 11% can be written as the decimal 0.11.

Final answer:
None of the given expressions are equivalent to g^5, as they all include the number 9. For a proper understanding, g^5 means multiplying g by itself five times (g x g x g x g x g). In exponentiation, such as (10²)³, exponents are multiplied to get the result (10&sup6;).
Explanation:
The expression g^5 represents g multiplied by itself 5 times. Looking at the given options, it is clear that none of them are equivalent to g^5 since they all involve the number 9, not the variable g. However, to understand the concept, if you were to express g^5 in a long form similar to the options, it would be g x g x g x g x g.
When discussing raising a number to an exponent, such as in (10²)³, you multiply the exponents, resulting in 10&sup6;. This comes from the law of exponents, which tells us that (a²)³ = a²×³. In this case, you would multiply 2 and 3 to get 6 as the new exponent for a.
This concept also applies to expressions inside parentheses raised to a power, affecting everything inside the parentheses. In the case of (27x³)(4x²), each term within the parentheses must be raised to the indicated power.

C. (1/2 , -1/8)
D. (5/9, -1/9)
Option A
The solution is [tex](0, \frac{-1}{4})[/tex]
Solution:
Given system of equations are:
3x + 6y = 1 ------ eqn 1
x - 4y = 1 ------ eqn 2
We have to find solution to system of equations
We can use substitution method
From eqn 2,
x = 1 + 4y -------- eqn 3
Substitute eqn 3 in eqn 1
3(1 + 4y) + 6y = 1
3 + 12y + 6y = 1
18y = 1 - 3
18y = -2
Divide both sides by 18
[tex]y = \frac{-2}{18}\\\\y = \frac{-1}{4}[/tex]
Substitute the above value of y in eqn 3
[tex]x = 1 + 4 \times \frac{-1}{4}\\\\x = 1-1\\\\x = 0[/tex]
Thus solution is [tex](0, \frac{-1}{4})[/tex]

2 x minus 5 y = negative 21. 3 x minus 3 y = negative 18.
What are the resulting equations?
6 x minus 15 y = negative 63. Negative 15 x + 15 y = 90.
6 x minus 15 y = 63. Negative 15 x + 15 y = 90.
6 x minus 15 y = negative 63. Negative 15 x + 15 y = negative 90.
6 x minus 15 y = negative 63. Negative 15 x + 15 y = 90.
Answer:
Therefore the required resulting equation is
[tex]6x-15y=-63\\-15x+15y=90[/tex]
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90
Step-by-step explanation:
Given:
[tex]2x-5y=-21[/tex] ......................Equation ( 1 )
[tex]3x-3y=-18[/tex] ......................Equation ( 2 )
To Find:
Expression after multiplying to eliminate y term,
Solution:
So to eliminate 'y' term we need to multiply equation 1 by a constant 3 and equation 2 by a constant -5, such that equations becomes
[tex]3(2x-5y)=3\times -21\\\\6x-15y=-63[/tex] .....( 1 )
[tex]-5(3x-3y)=-5\times -18\\\\-15x+15y=90[/tex] .....( 2 )
so now by adding new equation one and two we can eliminate y term that means -15y and +15y will get cancel,
Therefore the required resulting equation is
[tex]6x-15y=-63\\-15x+15y=90[/tex]
6 x minus 15 y = negative 63.
Negative 15 x + 15 y = 90

Answer:
20 km
General Formulas and Concepts:
Algebra I
Reading a Cartesian PlaneStep-by-step explanation:
We can disregard the length of the line from the Library and the House, as Davina does not use that path at all.
We know that 1 unit on the grid represents 1 km. We define the lengths of the route from the graph:
Davina's House to School = 4 units = 4 km
School to Library = 6 units = 6 km
The entire trip Davina takes from House to Library would be 4 km + 6 km = 10 km total.
We also know that Davina takes the same route back from the Library to House. It would be the same exact route and length. Therefore:
2(10 km) = 20 km total

What is the value of -36÷(-4/9)
The value of -36 divided by (-4/9) is 81, which is found by multiplying -36 with the reciprocal of (-4/9), giving the result 324/4, which simplifies to 81.
To find the value of -36 divided by (-4/9), you can think of division by a fraction as multiplication by its reciprocal. So, the problem changes from division to multiplication: -36 * (-9/4). To solve this:
First, multiply the numerators: -36 * -9 = 324.
Then, multiply the denominators: 1 * 4 = 4.
Now, divide 324 by 4 to get 81.
Therefore, the value of -36 divided by (-4/9) is 81.

The sum of two numbers is 100 and their difference is -20. What are the two numbers?
Answer:
x=40 and y= 60
Step-by-step explanation:
step:1
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
Step :2
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
Step :3
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60

Step-by-step explanation:
LCD is the least common denominator of fractions. LCD represents the smallest number that can be used as a common denominator for a particular set of fractions.
The given equation is [tex]\frac{5}{2x} + \frac{1}{4} = \frac{9}{2x}[/tex]
Here we can take LCD as 4x because 4x is divisible by 2x as [tex]\frac{4x}{2x} = 2[/tex], 4x is divisible by 4 as [tex]\frac{4x}{4} = 1[/tex]
therefore we can write
[tex]\frac{5}{2x} + \frac{1}{4} = \frac{9}{2x} \hspace{0.2cm} \Rightarrow \hspace{0.2cm} \frac{10}{4x} + \frac{x}{4x} = \frac{18}{4x} \hspace{0.2cm} \Rightarrow \hspace{0.2cm} \frac{x + 10}{4x} = \frac{18}{4x}[/tex]
now we can eliminate the LCD from both sides of the equation and we get
x + 10 = 18 [tex]\therefore[/tex] x = 18 - 10 [tex]\therefore[/tex] x = 8.

How do you work out this problem using completing the square x2 - 4x - 80 = 0
Answer:
A value that satisfies this equation is called a root, zero or solution of the equation!! We have three ... Solve each by factoring. 1) x2 + 4x -5 = 0 ... Follow the explanation and sample problem to review completing the square.
Step-by-step explanation:
x^2 - 4x = 80
x^2 - 4x + 4 = 80 + 4 (Divide b, which is 4, by 2 and square it.)
x^2 - 4x + 4 = 84
sqrt(x + 2)^2 = sqrt(84)
x + 2 = plus or minus sqrt(84)
Subtract 2 from both sides
x = -2 plus or minus sqrt(84)

Find an equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)
Answer:
[tex](x+5)^{2}=-4(y+3)[/tex]
Step-by-step explanation:
Given:
Focus point = (-5, -4)
Vertex point = (-5, -3)
We need to find the equation for the parabola.
Solution:
Since the x-coordinates of the vertex and focus are the same,
so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.
The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.
Substitute y = -4 and k = -3.
[tex]-4 = -3+p[/tex]
[tex]p=-4+3[/tex]
[tex]p=-1[/tex]
So the standard form of the parabola is written as.
[tex](x-h)^{2}=4p(y-k)[/tex]
Substitute vertex (h, k) = (-5, -3) and p = -1 in the above standard form of the parabola.
So the standard form of the parabola is written as.
[tex](x-(-5))^{2}=4(-1)(y-(-3))[/tex]
[tex](x+5)^{2}=-4(y+3)[/tex]
Therefore, equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)
[tex](x+5)^{2}=-4(y+3)[/tex]
Bridget takes a 5-inch by 4-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite corner. Now Bridget has two equally sized triangles of fabric. What is the perimeter of each triangle? If necessary, round to the nearest tenth.
Answer:
Perimeter of each triangles are equivalent to 15.4 inches.
Step-by-step explanation:
Given:
A rectangle :
Length of the rectangle = 5 inches
Width of the rectangle =4 inches
As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.
The diagonal will be treated as the hypotenuse.
Lets say that the length of the hypotenuse is 'x'.
Using Pythagoras formula:
⇒ [tex](hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}[/tex]
Plugging the values:
⇒ [tex]hypotenuse = \sqrt{5^2+4^2}[/tex]
⇒ [tex]hypotenuse = \sqrt{25+16}[/tex]
⇒ [tex]hypotenuse =\sqrt{41}[/tex]
⇒ [tex]hypotenuse = 6.40[/tex] inches
Now we have to find the perimeter :
Perimeter = Summation of length of all sides.
So,
Perimeter of each triangle = (length + width + hypotenuse)
⇒ [tex]Perimeter =(5+4+6.4)[/tex]
⇒ [tex]Perimeter =15.4[/tex] inches
Perimeter of each triangle, as they are equally sized are same that is 15.4 inches.
Write the inequality shown in the graph below:
Step 1) Identity two points on the boundary line.
Two such points are (0,7) and (1,5)
-----------------------------
Step 2) Find the slope of the line through those two points
m = (y2-y1)/(x2-x1)
m = (5-7)/(1-0)
m = -2/1
m = -2
The slope is -2
-----------------------------
Step 3) Use the point slope form to get the y = mx+b form
y - y1 = m(x - x1) ..... point slope form
y - 7 = -2(x - 0)
y - 7 = -2x
y = -2x+7
A quicker way is to just note that 7 is the y intercept as visually shown, so b = 7. Which allows us to go from y = mx+b to y = -2x+7
-----------------------------
Step 4) The boundary line is y = -2x+7. This is a dashed line so we will use either a less than sign, or a greater than sign. There will be no "or equal to" as part of the inequality sign.
The shaded region is below the dashed boundary line, so we use a less than sign.
Change y = -2x+7 into y < -2x+7
----------------------------
Step 5) Change into standard form (optional)
y < -2x+7
2x+y < 7 ... add 2x to both sides
==========================================
Final Answer: y < -2x+7 or 2x+y < 7The answer will depend on if you want slope intercept form or standard form.
