With y=2x-4
Answer: 8, 0, -12
1. This is the equation of a line y=mx +b. All you have to do it substitute your x values into the x in the equation.
y=2(6)-4
y=8
y=2(2)-4
y=0
y=2(-4)-4
y=-12
Just plug in the values for what you are given, you plug in the value for x and solve for y.
For this case we have a function of the form [tex]y = f (x)[/tex]
Where [tex]f (x) = 2x-4[/tex]
We must find the values of "and" when:
[tex]x = 6\\y = 2 (6) -4\\y = 12-4\\y = 8[/tex][tex]x = 2\\y = 2 (2) -4\\y = 4-4\\y = 0[/tex][tex]x = -4\\y = 2 (-4) -4\\y = -8-4\\y = -12[/tex]ANswer:

Sara Blake's grandmother gave her $3000.00 to save for college. She put it in a savings account that earns 6% interest per year. The money was in the account for 8 years. How much simple interest did she earn?
• P is the principal amount, $3000.00.
• r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
• t is the time involved, 8 years time periods.
• So, t is 8 year time periods.
To find the simple interest, we multiply 3000 × 0.06 × 8 to get that:
The interest is: $1440.00

A building contractor has a piece of crown molding that is 48 ½ inches long. He cuts off one piece measuring 10 ¼ inches and another piece 2 feet ⅛ inch.How much crown molding does he have left?
Answer:
14 1/8 inches of molding
Step-by-step explanation:
In order to find the solution, we'll have to do 2 fractions subtractions.
To be able to subtract fractions, we have to make sure they are placed in the same denominator. So, the first thing we'll do is to convert all the numbers in 8th, because that's the greatest denominator.
[tex]48 \frac{1}{2} = 48 \frac{4}{8} = \frac{(48 * 8) + 4}{8} = \frac{388}{8}[/tex]
[tex]10 \frac{1}{4} = 10 \frac{2}{8} = \frac{(10 * 8) + 2}{8} = \frac{82}{8}[/tex]
For the last one, we'll first convert the 2 feet into 24 inches.
[tex]24 \frac{1}{8} = \frac{(24 * 8) + 1}{8} = \frac{193}{8}[/tex]
Now, we'll subtract each of the two pieces cut from the original molding's length, first the 10 1/4 inches piece
[tex]\frac{388}{8} - \frac{82}{8} = \frac{388 - 82}{8} = \frac{306}{8}[/tex]
then the 2 feet 1/8 piece
[tex]\frac{306}{8} - \frac{193}{8} = \frac{306 - 193}{8} = \frac{113}{8} = 14 \frac{1}{8}[/tex]
So, the contractor is left with 14 1/8 inches of molding.
There are four steps for converting the equation x^2+y^2+12x+2y-1=0 into standard form by completing the square. Complete the last step.
Answer:
(x + 6)² + (y + 1)² = 36 + 1 + 1
Step-by-step explanation:
using the steps given, we are left with:
x² + 12x + 36 + y² + 2x + 1 = 38
we can factor each term in parentheses:
(x² + 12x + 36) + (y² + 2x + 1) = 36 + 1 + 1
lets start with x² + 12x + 36. we factor by finding 2 numbers that add up to 12 and when multiplied together get 36. the answer is 6. so we can factor:
(x + 6)²
next we factor y² + 2x + 1. the same rules apply, and this number would be 1.
(y + 1)²
we have the following:
(x + 6)² + (y + 1)² = 36 + 1 + 1
to simplify the right side, we add the terms, then square it as well to find the radius of the circle, in which the formula is (x - h)² + (y - k)² = r²
(x + 6)² + (y + 1)² = 38²
(x + 6)² + (y + 1)² = 1444
(x + 6)² + (y + 1)² = √1444
(x + 6)² + (y + 1)² = 38
this is the final form
If 25% of 150 is equal to 700 percent of n, then what number is n equal to?
Step-by-step explanation:
"Of" means multiplication, and percent means out of 100.
25/100 × 150 = 700/100 × n
75/2 = 7n
n = 75/14
n ≈ 5.357
The number n is equal to [tex]\frac{75}{14}[/tex] .
What is percentage ?Percentage is a ratio of output to total that can be expressed as a fraction of 100.
We have,
According to the question,
25% of 150 = 700 % of n,
Here,
n = number
Now,
Solving,
25% of 150 = 700 % of n
i.e.
[tex]\frac{25}{100} *150=\frac{700}{100} n[/tex]
On solving we get,
[tex]\frac{75}{2} =7n[/tex]
⇒
[tex]n=\frac{75}{14}[/tex]
So, the value of n is [tex]\frac{75}{14}[/tex],
Hence, we can say that the number n is equal to [tex]\frac{75}{14}[/tex] .

125= 25a
125/25= 25a/25
a= 5 !
Answer:
a = 5
Step-by-step explanation:
We are given 3 x 3 matrix and the determinant of the matrix is -19.
We need find the value of "a" in the given matrix.
[tex]\left[\begin{array}{ccc}-6&7&1\\a&-3&4\\-6&4&-3\end{array}\right][/tex]
determinant (D) = -6[(-3)(-3) − (4)(4)] − 7[a(-3) − (4)(-6)] + 1[a(4) − (-3)(-6)]
-19 = -6[9 - 16] -7[-3a +24] +1[4a - 18]
-19 = -6[-7] +21a - 168 + 4a - 18
-19 = 42 + 21a -168 + 4a - 18
Simplify the like terms, we get
-19 = 25a - 144
25a = -144 + 19
25a = 125
Dividing both sides by 25, we get
a = [tex]\frac{125}{25}[/tex]
a = 5
So the value of a is 5.
In how many different ways can a committee of 5 people be chosen from a group of 18?
Answer:
8568
Step-by-step explanation:
You have to choose 5 out of 18, and the order does not matter. So you're looking for the number of combinations, not permutations.
So you have to find 18C5.
nCr = n!/(n-r)!r!
so 18C5 = 18!/13!5!
= (18 * 17 * 16 * 15 * 14 * 13!)/ 13!5!
= 18*17*16*15*14/5*4*3*2*1
= 8568
Hope it helps :)
The total number of ways to select a committee of 5 people from a group of 18 is 8568.
Explanation:The question is asking for the total number of ways to select 5 people from 18. This is a commonly encountered problem in combinatorics, a mathematic field that deals with countable structures. To solve this, we use the combination formula, usually denoted as nCr where n is total items and r is number of items to choose. In this case, we use the combination formula C(18,5) where 18 is the total number of people and 5 is the committee size.
The formula for combination (nCr) is:
n! / (r!(n - r)!)
where '!' signifies a factorial which is the product of an integer and all the integers below it.
Inserting the numbers into the formula gives us:
18! / (5!(18 - 5)!) = 8568
So, there are 8568 different ways to choose a committee of 5 people from a group of 18.

yasmine uses 1/3 cup of water for 1 serving of a spaghetti sauce. she wants to make 3 3/4 servings of spaghetti sauce. how much water will yasmine need?
The answer is 1 and 3/4
Final answer:
Yasmine needs 1 1/4 cups of water to make 3 3/4 servings of spaghetti sauce.
Explanation:
Yasmine uses 1/3 cup of water for 1 serving of spaghetti sauce. She plans to make 3 3/4 servings of the sauce. To find out the total amount of water she will need, we first convert 3 3/4 servings to an improper fraction which is 15/4 servings. We then multiply this by the amount of water needed for one serving (1/3 cup).
Here's the calculation:
(15/4) servings × (1/3) cup/serving = (15/4) × (1/3) = 15/12 cups
Simplify 15/12 cups to get 5/4 cups or 1 1/4 cups.
Therefore, Yasmine needs 1 1/4 cups of water for 3 3/4 servings of spaghetti sauce.

student tickets for the football game cost $12 each and adult ticket cost $20 $1,720 was collected for the 120 ticket sold at last game which system of equations can be used to solve for the number of each kind of ticket sold
Answer:
85 student tickets and 35 adult tickets were sold.
Step-by-step explanation:
Howdy!
We know that student tickets cost $12, adult ticket cost $20 and 120 tickets were sold.
So:
$12×A + $20×B = $1,720. Where A and B are the number of student tickets and adult tickets sold, respectively.
Given that 120 tickets were sold in total, we have that:
A + B = 120
So the system of equations to be solved is the following:
$12×A + $20×B = $1,720 (1)
A + B = 120 (2)
Solving for 'A' in equation (2) we get:
A = 120 - B
Substituting this value into equation (1) we get:
$12×(120 - B) + $20×B = $1,720
Solving for 'B' we have:
$12×(120 - B) + $20×B = $1,720
$1,440 - $12×B + $20×B = $1,720
$1,440 + $8×B = $1,720
$8×B = $1,720 - $1,440
$8×B = $280
B = 35 tickets.
Given that B = 35, then A = 120 - 35 = 85 tickets.
So 85 student tickets and 35 adult tickets were sold.
Answer:
Students=85
Adults=35
Step-by-step explanation:
-12s-20a=-1720
20k+20a=2400
8k=680
k=85
85+a=120

Write the quadratic function f(x) = x2 - 5x + 3 in vertex form.
A) f(x) = (x - 2.5)2 + 3
B) f(x) = (x + 2.5)2 + 3
C) f(x) = (x - 2.5)2 - 3.25
D) f(x) = (x + 2.5)2 - 3.25
Answer:
C. [tex]f(x) = (x-2.5)^{2}-3.25[/tex]
Step-by-step explanation:
The vertex form for a quadratic function is:
[tex]f(x) = a(x-h)^2+k[/tex]
Then, you expand the binomial and get:[tex]f(x) = a(x^2-2hx +h^2) + k[/tex]
Now you distribute and get the first form:[tex]f(x) = ax^2-2ahx +ah^2 + k[/tex]
You know that the general form for a quadratic function is:[tex]f(x) = ax^2+bx+c, Second\ form[/tex]
You compare the two forms that you have and finding h and k:[tex]ax^2+2ahx +ah^2 + k = ax^2+bx+c[/tex]
Finding h from the coefficient of X:[tex]-2ah = b[/tex]
[tex]h = -\frac{b}{2a}[/tex]
from the quadratic function given you know that a = 1 , b = -5 and c = 3, thus:
[tex]h = -\frac{(-5)}{2(1)}=2.5[/tex]
Finding k from the third coefficient:[tex]ah^2+k = c[/tex]
[tex]Isolate\ k =>\ k = c-ah^2[/tex]
You know c,a and h, so replace the values:
[tex]k = 3-(1)(2.5)^2 \\ k = 3-6.25\\ k = -3.25\\[/tex]
• Finally replace the values for a, h and k in the vertex form:
[tex]f(x) = a(x-h)^2+k\\ f(x) = (1)(x-2.5)^2+(-3.25)\\ f(x) = (x-2.5)^2-3.25[/tex]
So answer is C. [tex]f(x) = (x-2.5)^2-3.25[/tex]

For questions 18-20 determine if line segment AB and line segment CD are parallel, perpendicular or neither
Answer:
Part 18) Lines AB and CD are perpendicular
Part 19) Lines AB and CD are parallel
Part 20) Lines AB and CD are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal each other (the product of their slopes is equal to -1)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Part 18) we have
[tex]A(-4,3),B(2,-12),C(10,5).D(0,1)[/tex]
step 1
Find the slope AB
substitute the given values in the formula
[tex]m=\frac{-12-3}{2+4}[/tex]
[tex]m=-\frac{15}{6}[/tex]
step 2
Find the slope CD
substitute the given values in the formula
[tex]m=\frac{1-5}{0-10}[/tex]
[tex]m=\frac{4}{10}[/tex]
[tex]m=\frac{2}{5}[/tex]
step 3
Compare the slopes
[tex]-\frac{15}{6} \neq \frac{2}{5}[/tex] ----> the lines are not parallel
[tex]-\frac{15}{6}*\frac{2}{5}=-1[/tex] ----> the lines are perpendicular
Part 19) we have
[tex]A(2,3),B(8,-15),C(-2,2).D(-5,11)[/tex]
step 1
Find the slope AB
substitute the given values in the formula
[tex]m=\frac{-15-3}{8-2}[/tex]
[tex]m=-\frac{18}{6}=-3[/tex]
step 2
Find the slope CD
substitute the given values in the formula
[tex]m=\frac{11-2}{-5+2}[/tex]
[tex]m=-\frac{9}{3}=-3[/tex]
step 3
Compare the slopes
[tex]-3=-3[/tex] ----> the lines are parallel
Part 20) we have
[tex]A(5,6),B(-1,6),C(-2,-7).D(-2,-4)[/tex]
step 1
Find the slope AB
substitute the given values in the formula
[tex]m=\frac{6-6}{-1-5}[/tex]
[tex]m=\frac{0}{-6}=0[/tex] ----> is a horizontal line parallel to the x-axis
step 2
Find the slope CD
substitute the given values in the formula
[tex]m=\frac{-4+7}{-2+2}[/tex]
[tex]m=\frac{3}{0}[/tex] -----> is undefined (is a vertical line, parallel to the y-axis)
step 3
Compare the slopes
The lines are perpendicular (because the x-axis and the y-axis are perpendicular)
The classification of line segments AB and CD as parallel, perpendicular, or neither depends on the slopes of the lines. If the slopes are equal, the segments are parallel; if the slopes are negative reciprocals, the segments are perpendicular. Without specific locations or further details for these segments, a definitive determination can't be made.
Explanation:In order to determine if line segment AB and line segment CD are parallel, perpendicular, or neither, we must consider the slope they form when plotted on a Cartesian plane. If they have the same slope, they are parallel. If the slopes are negative reciprocals of each other, they are perpendicular. If neither of these are the case, then they are neither parallel nor perpendicular.
For example, consider line segment AB located at points A (1, 3) and B (3, 7), and line segment CD located at points C (2, 4) and D (4, 8). The slope of AB (m1) can be calculated as (7-3) / (3-1) = 2 and the slope of CD (m2) as (8-4) / (4-2) = 2. Since m1 = m2, AB is parallel to CD.
While this provides a basic approach, without specific values or further information about AB and CD, a definitive classification cannot be made.

How do you solve to get y?
Answer:
y = 64
Step-by-step explanation:
Using the rule of logarithms
• [tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{y}[/tex] 4 = [tex]\frac{1}3}[/tex], then
4 = [tex]y^{\frac{1}{3} }[/tex]
Cube both sides
4³ = ([tex]y^{\frac{1}{3} }[/tex])³, hence
y = 64
plz help thank you very much!
Answer:
(1, - 4 )
Step-by-step explanation:
To find the y- coordinate, substitute x = 1 into the equation
y = (3 × 1) - 7 = 3 - 7 = - 4
The missing value is -4.
Since you already know that x = 1, substitute that into the equation and simplify. y = 3(1) - 7
Anything times 1 equals itself. y = 3 - 7
Subtract. y = -4
