Answer: y= - 4x+18
Step-by-step explanation:
Equation: y=mx+b
***remember: b is the y-intercept and m is the slope.
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
3= x1
2= x2
6= y1
10=y2
m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4
m=-4
Now we have y=-4x+b , so let's find b.
You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:
(3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.
(2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.
Equation of the line: y=-4x+18

Consider the function represented by the equation y-6x-9 = 0. Which answer shows the equation written in function
notation with x as the independent variable?
O F(x) = 5x + 9
O f(x) = 1/3 x + 2 / 2
Of) = 5y+9
O fox = 1/3 + 2 / 2
Answer:
f(x) = 5x+9
Step-by-step explanation:
This meets the criteria:
function notation - all this means is replace the'y' with 'f(x)
x as the independent variable - basically means don't change the letter for x
The equations in the system below are equivalent.
y = 2 (x + 4). Y = 2 x + 8
How many solutions does the system have?
no solution
one unique solution
two solutions
an infinite number of solutions
Answer:The answer would be infinite solutions
Step-by-step explanation:
Answer:
D. an infinite number of solutionsStep-by-step explanation:
In order to know that this is true, you must do simple steps to solve it. The first equation (y = 2 (x + 4)) is unsolved. In order to make it equal to the second equation (Y = 2 x + 8
), you must first use the distributive property, so multiply the x and the 4 in the first equation to get Y= (2x + 8), remove the parenthesis, and now, the equations are equal. Since they are equal, they overlap each other on the graph, so any number replacing x will change both equations equally, so they will forever overlap no matter what.

Cara has two pieces of ribbon, one 15 inches long and the other 20 inches long. To decorate an album, she wants to cut them up to produce many pieces of ribbon that are all of the same length, with no ribbon left over. What is the greatest length, in inches, that she can make them?
Answer:
5 inches
Step-by-step explanation:
Given that :
There are two pieces of ribbon with length:
15 inches and 20 inches
To cut ribbon into equal sizes with no ribbons left ; the greatest length in inches of the ribbon would be :
Calculate the greatest common factor of both lengths : 15 inches and 20 inches
____15___20
_5__ 3___4
OR
Find the factors of 15 and 20 and pick the greatest common to both
15 : 1, 3, 5, 15
20 : 1, 2, 4, 5, 10, 20
Greatest factor common to both = 5
Hence the greatest length she can cut the ribbons into without any leftover is 5 inches
Aston University creates a 10 digit student number as the University enrolls each student. The first two characters must be a digit 1 through 9. The next seven characters can be anything and the last digit just can’t be the same as the ninth character (i.e. the previous digit). How many student numbers are possible?
Answer:
The number of student numbers that are possible = 729,000,000 student numbers
Step-by-step explanation:
The number of possible numbers that can take the place of the first two digits = 9 possible numbers each
The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each
The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each
The total number of possible numbers is given as follows;
9 × 9 × 10⁶ × 9 = 729000000 possible student numbers
some number is added to itself the result is multiplied by eight is four what is that number
Answer:
X=1/4
Step-by-step explanation:
(x+x)*8=4
(2x)*8=4
16x=4
X=4/16=1/4
Answer:
0.25
Step-by-step explanation:
First...
Assume that the number is x and make an equation.
(x + x) 8 = 4
Next...
Add.
(2x) 8 = 4
After that...
Divide.
2x = 4/8 so 2x = 1/2
Finally...
Divide more
x = 1/4 or 0.25
So your answer is 0.25.
I did double-check.
5x-2y ≤ 20 can you guys solve this.
Answer:
Step-by-step explanation:
Let's solve for x.
5x−2y≤20
Step 1: Add 2y to both sides.
5x−2y+2y≤20+2y
5x≤2y+20
Step 2: Divide both sides by 5.
5x /5 ≤ 2y+20 /5
x≤ 2 /5 y+4
Answer:
x≤ 2 /5 y+4
Let's solve for y.
5x−2y≤20
Step 1: Add -5x to both sides.
5x−2y+−5x≤20+−5x
−2y≤−5x+20
Step 2: Divide both sides by -2.
−2y /−2 ≤ −5x+20
−2 y≥ 5 /2 x−10
Answer:
y≥ 5 /2 x−10

The price when selling on installments be $822025.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that the value of a house is $655,000 in cash, but when selling it on installments, you are charged 25.5% of its price.
Assume the price when selling on installments be $x. Then, we can write new price as -
[x] = 655000 + {25.5% of 655000}
[x] = 655000 + {25.5/100 x 655000}
[x] = 655000 + {25.5 x 6550}
[x] = 655000 + 167025
[x] = $822025
Therefore, the price when selling on installments be $822025.

how can you find a ratio in a bar graph
Divine the total number of the entire chart by the number of a single line or bar to give you the ratio in a bar or line chart. For example, if a bar or line represented 5 in a chart with a total of 30, you would divide 30 by 5. This would give you a result of 6. Therefore, the ratio would be 6:1.
Determine the intercepts of the line.
2x + 5y = -6
y-intercept: ?
r-intercept: ?
Answer:
y-int = (0,-6/5)
x-int = (-3,0)
Step-by-step explanation:
to find the ints you have to replace the values by zero
y-int :
2(0) + 5y = -6
0 + 5y = -6
5y = -6
y = -6/5
y-int = (0,-6/5)
x-int:
2x + 5(0) = -6
2x + 0 = -6
2x = -6
x = -6/2
x = -3
x-int: (-3,0)

Point slope question
Answer: (y + 3) = -1/3 (x - 2)
Step-by-step explanation:
Point-slope form has the form of
y - y1 = m (x - x1)
Where
y1 is the y-value of a point on the line
x1 is the x-value of a point on the line
m is the slope of the line
The problem already gives a point on the line, (2, -3)
(y + 3) = m (x - 2)
Remember to put the opposite value of the x and y values. (In other words, do NOT write (y - 3) = m (x + 2) )
The slope of a perpendicular line is the opposite reciprocal of slope of the line it is perpendicular to. The perpendicular line given in the equation is
3x - y = 4
When rearranged to slope-intercept form, we get
y = 3x - 4
Meaning the slope of the perpendicular line is 3. The opposite reciprocal of positive three is negative one-third. Therefore, the slope of the line we are solving for is -1/3.

What are the vertices of ΔA'B'C produced by T⟨−3, 6⟩ (ΔABC) = ΔA'B'C?
Answer: (3x - 12, 3y +6)
Step-by-step explanation:A dilation is a transformation that produces an image that is the same shape as ... The dilation (centered at O with a scale factor of 2) of ΔABC = ΔA'B'C' making ... from O to the vertices of ΔA'B'C' are twice the distances from O to ΔABC. ... Apply the dilation formula when centered at origin: (3(x - 4), 3(y + 2)) = (3x - 12, 3y + 6)
