Answer:
y = -4/9x - 10/9
Step-by-step explanation:
(-7, 2) and (2, -2)
slope: y2-y1/x2-x1
-2-2 / 2+7
-4/9
y = mx + b
y = -4/9x + b
plug in (2,-2)
-2 = -8/9 + b
b = -10/9
y = -4/9x - 10/9
Answer:
[tex]y=-\frac{4}{9} x-\frac{10}{9}[/tex]
Step-by-step explanation:
(-7, 2) and (2, -2)
Slope:
m=(y2-y1)/(x2-x1)
m=(-2-2)/(2+7)
m=(-4)/9
m= -4/9
y - y1 = m(x -x1)
y - 2 = -4/9(x + 7)
y - 2 = -4/9x - 28/9
y = -4/9x -10/9

A mom buys a water bottle and a jersey for each of the 10 players on the volleyball team. Each jersey costs $6.70. The mom spends a total of $221 for water bottles and jerseys. Enter an equation that modes the situation with u, the cost of one water bottle.
Answer:
one water bottle cost 15.4 dollars
Step-by-step explanation:
6.7 times 10 is 67
therefore the mom spent 67 dollars on jerseys
221 (total) minus 67 ( jersey) = 154
therefore she spent 154 dollars on water
154 divided by 10
=15.4
the water bottles cost 15.4 dollars

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower
bed. The diagram shows the flower bed and its dimensions in feet.
4w? + 3w - 1
5w - 2
Which expression represents the area in square feet that the homeowner will cover with fertilizer?
Answer:
The answer is D
Step-by-step explanation:
The 4w^2 stays the same because there are no like factors, then you add the 5w and 3w then get 8w...-1+ (-2) is -3
The polynomial that represents the area in square feet will be 20w³ + 7w² - 11w + 2. Then the correct option is B.
What is a polynomial?A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed.
A mortgage holder is building a blossom bed on the lawn. He intends to put a layer of compost over the whole bloom bed. The chart shows the blossom bed and its aspects in feet.
4w² + 3w - 1 and 5w - 2
The polynomial that represents the area in square feet will be given as,
⇒ (4w² + 3w - 1) x (5w - 2)
⇒ 20w³ + 15w² - 5w - 8w² - 6w + 2
⇒ 20w³ + 7w² - 11w + 2
The polynomial that represents the area in square feet will be 20w³ + 7w² - 11w + 2. Then the correct option is B.

Which expression will give you the phase shift when the standard form is f left parenthesis x right parenthesis equals a sine left parenthesis b x plus c right parenthesis plus d?
Answer:
[tex]Phase\ Shift = -\frac{c}{b}[/tex]
Step-by-step explanation:
See comment for complete question
Given
[tex]f(x) = Asin(bx+c)+d[/tex]
Required
Determine an expression for the phase shift
[tex]f(x) = Asin(bx+c)+d[/tex]
Factorize the expression in bracket
[tex]f(x) = Asin(b(x+\frac{c}{b}))+d[/tex]
The general expression is:
[tex]F(t) = A f(B(t - C/B)) + D[/tex]
Where:
C/B is the phase shift
By comparing the general expression with: [tex]f(x) = Asin(b(x+\frac{c}{b}))+d[/tex]
[tex]-\frac{C}{B} = \frac{c}{b}[/tex]
Multiply both sides by -1
[tex]\frac{C}{B} = -\frac{c}{b}[/tex]
Hence:
[tex]Phase\ Shift = -\frac{c}{b}[/tex]

if each data is increased by a constant K then find it's mean ?? answer fast pleaseeeeeeeeeee
Answer:
The mean is also increased by the constant k.
Step-by-step explanation:
Suppose that we have the set of N elements
{x₁, x₂, x₃, ..., xₙ}
The mean of this set is:
M = (x₁ + x₂ + x₃ + ... + xₙ)/N
Now if we increase each element of our set by a constant K, then our new set is:
{ (x₁ + k), (x₂ + k), ..., (xₙ + k)}
The mean of this set is:
M' = ( (x₁ + k) + (x₂ + k) + ... + (xₙ + k))/N
M' = (x₁ + x₂ + ... + xₙ + N*k)/N
We can rewrite this as:
M' = (x₁ + x₂ + ... + xₙ)/N + (k*N)/N
and (x₁ + x₂ + ... + xₙ)/N was the original mean, then:
M' = M + (k*N)/N
M' = M + k
Then if we increase all the elements by a constant k, the mean is also increased by the same constant k.

Answer:
Perpendicular = Y = 34.64 ft (Approx)
Base = X = 20 ft
Step-by-step explanation:
Given:
θ = 60°
Hypotenuse = 40 ft
Perpendicular = Y
Base = X
Find:
X and Y
Computation:
Sinθ = Perpendicular / Hypotenuse
Sin 60 = Y / 40
Perpendicular = Y = 34.64 ft (Approx)
Cosθ = base / Hypotenuse
cos 60 = X / 40
Base = X = 20 ft

The graph shows the relationship between the number of years after a car is purchased
and the car's value
Which statement correctly describes the relationship shown in the graph?
A)
The car's initial value is $18,000, and the car's value increases $2,000 each year.
B)
The car's initial value is $18,000, and the car's value increases $6,000 each year
C)
The car's initial value is $30,000, and the car's value decreases $2,000 each year.
D)
The car's initial value is $30,000, and the car's value decreases $6,000 each year
Answer:
C. The car's initial value is $30,000, and the car's value decreases $2,000 each year.
Step-by-step explanation:
first I looked at the graph and saw that the y-intercept(car's initial value) was 30,000 which allowed me to eliminate A and B. Then found the slope by using the [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]= slope formula. [tex]\frac{24,000-30,000}{3-0}=\frac{-6,000}{3}=-2,000[/tex]. This tells us that the slope is -2,000 which means that the value decreases by 2,000 each month. So the correct answer is C.
The car's initial value is $30,000, and the car's value decreases by $2,000 each year. the correct answer would be an option (C).
What is the slope of the line?The slope of a line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The given graph shows the relationship between the number of years after a car is purchased and the car's value.
As per the graph, we take two points (0, 30,000) and (6, 18,000)
Here slope of the given graph is equal to the car's value decreases by each year.
So slope = (18,000 - 30,000)/(6-0) = -12,000/6 = -2000
This means the car's value decreases by $2,000 each year.
Thus, the car's initial value is $30,000, and the car's value decreases by $2,000 each year.

The scores for a 25 - point quiz are listed below arranged from least to greatest. 7, 7, 12, 13, 15, 16, 16, 16, 18, 19, 20, 20, 20, 21, 21, 22, 23, 23, 24
Using the following guidelines , create a histogram for the class.
a. Determine the range of the sample
b. Determine the number of intervals by: Finding the square root of n. Round to the next higher whole number.
c. Determine the interval width: Width = Range/# Intervals. Round to the next higher whole number.
d. Create the categories.
e. Plot the data
Answer:
[tex]Range = 17[/tex]
[tex]Intervals = 5[/tex]
[tex]Widt = 4[/tex]
Step-by-step explanation:
Given
The above data
Solving (a): The range:
[tex]Range = Highest - Least[/tex]
Where
[tex]Highest = 24[/tex]
[tex]Least = 7[/tex]
So:
[tex]Range = 24 - 7[/tex]
[tex]Range = 17[/tex]
Solving (b): Number of intervals.
From the given data:
[tex]n = 25[/tex]
[tex]Intervals = \sqrt n[/tex]
[tex]Intervals = \sqrt {25[/tex]
[tex]Intervals = 5[/tex]
Solving (c): Interval width
This is calculated as:
[tex]Width = \frac{Range}{Intervals}[/tex]
[tex]Width = \frac{17}{5}[/tex]
[tex]Width = 3.4[/tex]
[tex]Widt = 4[/tex] --- round up
Solving (d): Create the categories
Based on the calculated parameters above, the categories are: 7 - 10, 11 - 14, 15 - 18, 19 - 22 and 23 - 26
Solving (e): The histogram
First construct the frequency table
Intervals ---- Frequency --- Midpoint
7 - 10 --------- 2 ---------------- 8.5
11 - 14 ---------- 2 ----------------- 12.5
15 - 18 -------- 5 ----------------- 16.5
19 - 22 -------- 7 ------ ----------- 21.5
23 - 26 ---------- 3 ----------------- 24.5
The midpoint is calculated by calculating the mean of the intervals.
For instance:
For class 7 - 10, the midpoint is: (7+10)/2 = 17/2= 8.5
This is applied to other classes too
The midpoint is then plotted against the frequency.
