Write 4/5 as an equivalent fraction in 3 different forms.
Data for length of the tail (in millimeters) and age (in days) of tadpoles is entered into a statistics software package and results in a regression equation of ŷ = 15 - 1.5x.
What is the correct interpretation of the slope if the length of the tail is the response variable and the age is the explanatory variable?
Using the slope concept, it is found that the correct interpretation is that each day, the length decreases by 1.5 millimetres.
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.b is the y-intercept, which is the value of x when y = 0.In this problem, the length of the tail, in millimetres, after x days, is given by:
[tex]y = 15 - 1.5x[/tex]
The slope is of [tex]m = -1.5[/tex], which means that each day, the length of the tail decreases by 1.5 millimetres.

Answer:
[tex]x = 26 \frac{1}{3} \\ [/tex]
[tex]y = 13 \frac{2}{3} \\ [/tex]
Step-by-step explanation:
x = 2y - 1
x - 2y = -1 ________(1)
x + y = 40________(2)
(2) - (1)
[tex]x + y - (x - 2y) = 40 - ( - 1) \\ x + y - x + 2y = 40 + 1 \\ 3y = 41 \\ y = \frac{41}{3} \\ y = 13 \frac{2}{3} \\ [/tex]
y = 13 2/3
[tex]x + y = 40 \\ x + 13 \frac{2}{3} = 40 \\ x = 40 - 13 \frac{2}{3} \\ x = 40 - \frac{41}{3} \\ x = \frac{3(40) - 41}{3} \\ x = \frac{120 - 41}{3} \\ x = \frac{79}{3} \\ x = 26 \frac{1}{3} \\ [/tex]

Flowers - Samantha and Maria purchased flowers. Samantha bought five roses for "r" dollars each and four daises for "d" dollars each. Altogether, Samantha spent $32 on flowers. Maria purchased one rose for "r" dollars apiece and six daisies for "d" dollars apiece - spending $22 total.
a) Write a system of equations (two linear equations) using appropriate variables.
b) Solve the system to find the cost of roses and daisies. Use any strategy that you've learned.
Answer:
part a[tex]5r + 4d = 32[/tex]
[tex]r + 6d = 22[/tex]
part bthe value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece
Step-by-step explanation:
part afor part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost
part bsolve the two equations simultaneously or by substitution.
let's do simultaneous
multiply the secondequation by 5
[tex]5r + 4d = 32[/tex]
[tex]5r + 30d = 110[/tex]
subtracting the two,
[tex]26d = 78[/tex]
therefore
[tex]d = 3 dollars[/tex]
find the value of roses,
[tex]5r + 4(3) = 32 \\ 5r = 32 - 12 \\ r = 4[/tex]

what is the answer to 2/5+5/10=
Answer:
[tex]\frac{2}{5\\}[/tex] + [tex]\frac{5}{10}[/tex]= [tex]\frac{9}{10}[/tex]
Step-by-step explanation:
Because this is not multiplication or diving you must find the same denominator, which is 10. Now, because 5/10 is already 10 I don't need to change that, but if you see that 2/5 does not have the denominator of 10. Then, I need to multiply 2 on the numerator and the denominator because 5(2) equals 10 and whatever is multiplied to the denominator has to be multiplied to the numerator. So. now the numerator is 4. Lastly, what you need to do is add them together. So, (2+5)=7 and the denominator is stays as 10 because it is addition. So, our final answer is 9/10

Answer:
domain: (-4, -2) ∪ [-1, 4]
range: (-5, 3)
Step-by-step explanation:
Domain
The domain is the horizontal extent of the graph. Here, it is comprised of two intervals. The left interval is open, as the function is not defined for x-values of -4 or -2. That interval is (-4, -2). The right interval is closed, as the function is defined for both x=-1 and x=4. That interval is [-1, 4]. The domain is the union of these two intervals.
D: (-4, -2) ∪ [-1, 4]
__
Range
The range is the vertical extent of the graph. The left portion of the graph has a range from -5 to 3, but neither of those values is included in it. That is, the range is an open interval: (-5, 3).
The right portion of the graph has a range from 1 to 2, including both of those values. This interval is already included in the interval (-5, 3), so only one interval is needed to describe the range:
R: (-5, 3)
