Answer:
5x- 9 is your expression
Step-by-step explanation:
Decreased means subtraction and the product of any two numbers is multiplication.
Division Keyword: Divided by, or Quotient of.
Multiplication Keyword: Product of, or Multiplied by.
Subtraction Keyword: Subtracted from, or Decreased by.
Addition Keyword: Added to, or Increased by.
If there is no Variable then place the common Variables: X, Y, Z.
Answer:
The expression is 5x-9.
Step-by-step explanation:
Product means to multiply, so you will multiply 5 and x which equals 5x
Decreased means subtracting, so you will subtract 9
9y-8x=63 How do I convert this into slope-intercept form?
Answer:
turn it into y=mx+b
Step-by-step explanation:
get y alone
add 8x to both sides
9y=63+8x
divide both sides by 9
63/9=7 8x/9= [tex]\frac{8x}{9}[/tex]
simplify
y=[tex]\frac{8}{9}[/tex]x+7Answer:
y = 0.8x + 7 or
y = [tex]\frac{4}{5}[/tex]x + 7
Step-by-step explanation:
The slope intercept formula is: y = mx + b
9y - 8x = 63
+8x +8x
= 9y = 63 + 8x
9y/9 = 63/9 + 8x/9 ←
We're getting rid of the 9 beside the y, so we have to divde every number by 9.
= y = 0.8x + 7 if you want the 0.8 as a fraction, it'll be [tex]\frac{4}{5}[/tex]

Step-by-step explanation:
A population of 2000 fish increases at an annual rate of 7.5%. Write the model, then predict how
many fish will there be in 10 years?
Answer:
The model is [tex]P(t) = 2000(1.075)^{t}[/tex].
There will be 4122 fish in 10 years.
Step-by-step explanation:
Exponentially increasing population:
An exponentially increasing population can be represented by the following model:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(t) is the population after t years, P(0) is the initial population, and r is the growth rate, as a decimal.
A population of 2000 fish increases at an annual rate of 7.5%.
This means that [tex]P(0) = 2000, r = 0.075[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2000(1+0.075)^t[/tex]
[tex]P(t) = 2000(1.075)^{t}[/tex]
This is the model.
How many fish will there be in 10 years?
This is P(10).
[tex]P(t) = 2000(1.075)^{t}[/tex]
[tex]P(10) = 2000(1.075)^{10} = 4122[/tex]
There will be 4122 fish in 10 years.

Answer:
(9)(27) also 243
Step-by-step explanation:
So, 3^2=9, and 3^3=27, so (3^2)(3^3) is equal to (9)(27) or 243
A 13.5 m fire truck ladder is leaning against a wall.
Find the distance the ladder goes up the wall if it
makes an angle of 43.8° with the ground.
To solve this problem you must apply the proccedure shown below:
1. You have the the 13.5-m fire truck ladder is leaning against a wall and the ladder makes an angle of 39 degrees 45 ' with the horizontal.
2. Then you have:
39 degrees 45'=39.75°
Sin(39.75°)=d/13.5
d=13.5xSin(39.75°)
d=8.63
solve for m : -5m + 14 = 9

Find 9079 + 1232 + 9786.
3(1.5x+9)= tell me NOW
Answer:
x = -6
Step-by-step explanation:
Simplifying
3(1.5x + 9) = 0
Reorder the terms:
3(9 + 1.5x) = 0
(9 * 3 + 1.5x * 3) = 0
(27 + 4.5x) = 0
Solving
27 + 4.5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-27' to each side of the equation.
27 + -27 + 4.5x = 0 + -27
Combine like terms: 27 + -27 = 0
0 + 4.5x = 0 + -27
4.5x = 0 + -27
Combine like terms: 0 + -27 = -27
4.5x = -27
Divide each side by '4.5'.
x = -6
Simplifying
x = -6

Maggie wants to buy a new energyefficient refrigerator. Her old refrigerator uses about 1200 kWh per year,while the new one would use about 400 kWh per year. Approximately how much money would Maggie saveper year if she buys the new refrigerator?
Answer:
800 Kwh
Step-by-step explanation:
To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity
How much did Maggie save?Let's first of all calculate the the difference in energy saved
Data;
old refrigerator = 1200kWhnew refrigerator = 400kWh[tex]1200 - 400 = 800kWh[/tex]
Maggie would've saved 800kWh in one year.
But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.
So, to determine how much she must've saved, we simply multiply $1 by 800kWh
[tex]1 * 800 = $800[/tex]
Using our assumptions, she would've saved $800 in one year.

Answer: 252
Step-by-step explanation:
0.392 is what percent of 28?
Pleasee
Answer:
28% of 0.392=0.10976
Step-by-step explanation:
1. We assume, that the number 0.392 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 0.392 is 100%, so we can write it down as 0.392=100%.
4. We know, that x is 28% of the output value, so we can write it down as x=28%.
5. Now we have two simple equations:
1) 0.392=100%
2) x=28%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
0.392/x=100%/28%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for what is 28% of 0.392
0.10976
