Answer:
5 + x = 21
Step-by-step explanation:
5 more than a number is 21. Write it in an equation.
5 + x = 21
-------------------------
Answer:
5+x=21
Step-by-step explanation:
A number 5 is the number added to the variable "X".
----> x+5=21. Hence “5 more than a number is 21. ” written as an algebraic expression is “x+5”.
So a number 5 more than x is 21 means that if you add x+5, you recive 21

Find the slope.
-2,15
0,3
4,-21
8,-45
Answer:
do you remeber the slope formula
y2 - y1 / x2 - x1
so pick two points from those 4 points ill pick -2,15 and 0,3
so 3 - 15 / 0 - 2 gives us -12/-2 or a slope of 6/1 or just 6
Can someone please give me the (Answers) to this? ... please ...
Answer:
a. locate the rise over run between points
b. y2-y1/x2-x1
c. m=slope in y=mx+b
Step-by-step explanation:
a) Use rise over run,
() count how far apart up/down the y's are, and how far apart left/right the x's are
() down in the y's mean it is negative
b) change in y over change in x
() y2 - y1 / x2 - x1
c) find the "m" when it is in slope-intercept form
() y = mx + b

For each year , the population of a forest of trees is represented by A(t)=115(1.025)t .In a neighboring forest, the population of the same type of tree is represented by the function B(t)=82(1.029)t .
Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 100 years? By how many?
Answer: Forest B has 71 more trees than forest A after 100 years.
Step-by-step explanation:
I'm assuming that both functions should read as follows: (the time, t, is shown as a power, instead as a multiplication).
A(t)=115(1.025)^t
B(t)=82(1.029)^t
Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.
A(100)=115(1.025)^(100)
A(100) = 1359
B(100) = 82(1.029)^(100)
B(100) = 1430
Forest B has 71 more trees than forest A after 100 years.
A particular bank offer 6% interest per year compound monthly Timothy wishes to deposit $1000 write a forumla for the Amount A Timothy after n months
A formula that could be used to find the future value of Timothy's account after n months is: [tex]A = 1005^{\frac{144}{n} }[/tex]
Given the following data:
Interest rate = 6%Principal = $1000Number of times compounded = 12Time = n months to years = [tex]\frac{12}{n} \;years[/tex]To write a formula for the Amount A Timothy has after n months:
Mathematically, compound interest is given by the formula:
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.P is the principal or starting amount.r is annual interest rate.n is the number of times the interest is compounded in a year.t is the number of years for the compound interest.Substituting the given parameters into the formula, we have:
[tex]A = 1000(1 + \frac{0.06}{12} )^{12\times \frac{12}{n} }\\\\A = 1000(1 + 0.005 )^{\frac{144}{n} }\\\\A = 1000(1.005 )^{\frac{144}{n} }\\\\A = 1005^{\frac{144}{n} }[/tex]

_x+5=4(–x–5) help pls
Answer:
Assuming the equation is: _x+5=4(–x–5) and not -x+5=4(–x–5),
Step-by-step explanation:
_x+5=4(–x–5)
_x+5=–4x–20
_x =–4x–25
_x +4x=–25
(4+_x) = -25
There is nothing left to do without more information.

Otherwise:
-x+5=4(-x-5)
-x+5=-4x-20
-3x = -25
x = -(25/3)

Answer:
25 mini loaves
Step-by-step explanation:
Using the first set you can divide and tell that 1 cup of flour is equal to 2.5 mini loaves, applying that to the other set you can inquire that it's true. So therefore what you need to do is multiply 2.5 times the amount of flour you are using.
10 cups = 25 mini loaves

At the after school Hawk Club meeting, there were four drinks you could choose from: orange soda, Coke, Dr. Pepper, and water. There were three snacks you could choose from: peanuts, fruit, and cookies. Each student may have only one drink and one snack.
Use the counting principle to find the number of choices available
Answer: 12 possible choices
Step-by-step explanation: there are 4 drink options, and 3 snack options so using the counting principle we would do 4 x 3 to get 12. You could also check individually since it is not a big number by doing: 1 choice with coke and peanuts, another with coke and fruit, etc.

Write an equation in Ax+By=C form for this line.
9514 1404 393
Answer:
5x -2y = 30
Step-by-step explanation:
The slope of the line ...
Ax +By = C
is -A/B. This means we can use A=5 and B=-2 in the equation we're looking for. The value of C will be one that makes the equation true at the given point.
5x -2y = 5(4) -2(-5)
5x -2y = 30

X/5 + 3 = 2 pls help
Answer:
x=-5
Step-by-step explanation:
Group all constants on the right side of the equation
Subtract 3 from both sides:
x/5+3-3=2-3
Simplify the arithmetic:
x/5=2-3
Simplify the arithmetic:
x/5=-1
Isolate the x
Multiply to both sides by 5:
x/5 ·5= -1 · 5
Group like terms:
1/5 · 5x = -1 · 5
Simplify the fraction:
x = -1 · 5
Simplify the arithmetic:
x = -5
