Answer: f(x) = x^2 - 4*x
Step-by-step explanation:
This is a quadratic equation, that can be written in factorized form as:
f(x) = A*(x - a)*(x - b)
Where A is a real number, a and b are the roots of the equation.
In the graph we can see that the graph intersects the x-axis at x = 0, and x = 4, then:
a = 0
b = 4
So the equation is:
f(x) = A*(x -0)*(x - 4) = A*x*(x - 4)
Now we can also see that, the arms of the exponential open up, this means that A is positive, and we also can see that f(2) = -4
Then:
f(2) = A*2*(2 - 4) = -4
= A*2*(-2) = -4
= A*-4 = -4
A = -4/-4 = 1
A = 1
Then the equation is:
f(x) = x*(x - 4) = x^2 - 4*x

how do you solve for exterior angle therom
Answers
Answer:
The interior angles of a triangle add to 180°:a + b + c = 180°
Angles c and d make a straight angle, which is 180°:d + c = 180°
So d + c equals a + b + c:d + c = a + b + c.
Subtract c from both sides:d = a + b.

A data set which could be represented by the box plot shown above include the following: B. 2, 3, 5, 5, 6, 7, 8, 8, 11.
What is a box plot?In Mathematics, a box plot is sometimes referred to as a box-and-whisker plot and it can be defined as a type of chart that is used for the graphical or visual representation of the five-number summary of a data set with respect to locality, skewness, and spread.
By using the box-and-whisker plot (box plot) shown in the image attached above, the five-number summary for the given data set include the following:
Minimum = 2.First quartile = 4.Median = 6.Third quartile = 8.Maximum = 11.By critically observing the box-and-whisker plots (see attachment), we can logically deduce that it represents all of the five-number summary for 2, 3, 5, 5, 6, 7, 8, 8, and 11.

A customer buys a CD for $15 and a video game. The customer pays a total of $42.80 for the two items, which includes 7% sales tax. Which equation can be used to find x, the cost of the video game before tax? 0.07 (15 + x) = 42.80 0.07 (42.8 minus 15) = x 1.07 (15 + x) = 42.80 1.07 (42.8 minus 15) = x
Answers
Answer:
1.07 (15 + x) = 42.80
Step-by-step explanation:
Given data
CD= $15
Let the cost of the video game be x
The total cost= 15+x
Hence the equivalent expression is
1.07 (15 + x) = 42.80
open bracket
16.05+1.07x= 42.80
42.80-16.05= 1.07x
26.75=1.07x
x= 26.75/1.07
x= 25
Check
7% tax for CD
=0.07*15
=1.05
total =1.05+15
=$16.05
7% tax for Video game
=0.07* 25
=1.75
total =1.75+25
=$26.75
In all
=26.75+16.05
=$42.8

To isolate the variable of x, simply add 16 to 11 which is 27 and now it is set up as 4.5x=27 and 27/4.5, it = 6
Answer:
Gray and all are right.
Step-by-step explanation:
4.5x + 16 = 11.5
4.5x = 11.5 - 16
4.5x = -4,5
x = -4.5/4.5
x = -1
4.5x + 27 = -9
4.5x = -9 - 27
4.5x = -36
x = -36/4.5
x = -8
4.5x - 16 = 11
4.5x = 11 + 16
4.5x = 27
x = 27/4.5
x = 6
-4.5x + 27 = 45
-4.5x = 45 - 27
-4.5x = 18
x = 18/-4.5
x = -4
A company donates to charity every year as its contribution to society. If the company makes a profit in that year, 2/9 of the profit will be allocated for donation. If the company incurs a loss, the company will also allocate 0.05 of the loss for donation. If the company makes a profit of RM43.2 million in a certain year
and incurs a loss of RM2.5 million and RM6.5 million respectively in two consecutive years, calculate the total donations the company would have allocated for charity in those three years.
can someone please help meee
Answers
Answer:
RM10.05 million
Step-by-step explanation:
year 1 profit= RM 43.2m yr 2 loss =RM 2.5 myr 3 loss=RM 6.5 mtherefore:
2/9 of 43.2
=9.6m
5/100 of 2.5m
=125,000
5/100 of 6.5m
=325,000
therefore total donations are :
9,600,000+125,000+325,000
=10,050,000

A store sells bottles of juice in boxes. Garth bought 18 bottles, Rico bought 36 bottles, and Mai bought 45 bottles. What is the maximum number of bottles in each box?
Answers
Answer:
The maximum number of bottles in each box is equal to 9.
Step-by-step explanation:
Garth bought 18 bottles, Rico bought 36 bottles, and Mai bought 45 bottles. We need to find the maximum number of bottles in each box. It can be calculated using HCF of 18, 36 and 45
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 45 are: 1, 3, 5, 9, 15, 45
Then the greatest common factor is 9.
So, there are 9 bottles in each box.

Using the coordinate (0, 0) and (200, 300)
Slope m = 300-0/200-0
m = 300/200
m = 1.5
Since the line pass through the origin, the y intercept is 0
Substitute m = 1.5 and b =0 into y = mx+b
y = 1.5x + 0
y = 1.5x
