Step-by-step explanation:
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

What were some of their hardships in r obstacles that Martin Luther king jr had in their life?
In your own words
Answer: I would say that some of the Three challenges Martin Luther King Jr. faced in the battle for equal rights included the opposition of "good" white people to his tactics, his realization that the only way to win civil rights was to proceed nonviolently, and pushback against his plan in the late 1960s to unite Black people and white people in a war on poverty.
Step-by-step explanation:
Answer:
Martin Luther king faced many hardships and challenges in the duration of his life. His right to freedom of speech was violated constantly, resulting in him to get arrested, threatened, bombed, and even stabbed. He was targeted by people who didn’t want change. They wanted things to stay the way they were, where segregation was enforced, and the inequality of races continued. Although he was a subject to violence all his life, he never gave up and his dream impacted the world and became a reality.

Calculus, second derivative. Please help! Show work, if possible please. Thanks! :)
Answer:
y''=sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)
Step-by-step explanation:
we are given y= csc x sec x
We use the rule for multiplying derivatives and the knowledge that the derivative of csc is -csc*cot and the derivative of sec is sec*tan to get
csc(x)*sec(x)*tan(x)+sec(x)*-csc(x)*cot(x)
which simplifies to
csc(x)*sec(x)*tan(x)-sec(x)*csc(x)*cot(x)
Using the same rules again (in tedium so they are not listed but can be inferred) we find the second derivative is
sec^3(x)*csc(x)+sec^2(x)*tan(x)-2cot(x)*csc(x)*sec(x)*tan(x)+cot^2(x)*csc(x)*sec(x)+csc^3(x)*sec(x)

Find the exact value of sin
how do you solve this (first equation) x=2y-1 (second equation) x+y=40
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]

Now
3³+11(2)-4(7)27+22-2849-2821Data 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.
