y-3=2(x+1) please please help
Answer:
y=2x+5
Step-by-step explanation:
distribute 2 to x and 1, do this by multiplying each.
you should get y-3=2x+2.
then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.
you then get the answer, y=2x+5.

If your car gets 28 miles per gallon and you travel 30 miles round-trip to work five days a week, how much do you pay each 4-week
month if gas is $3.05 a gallon? (Round your answer to 2 decimal places.)
please help
Answer:
You'd pay $65.35 every 4 weeks
Step-by-step explanation:
First you have to gather all the miles.
30 miles x 5 = 150
So that is 150 miles/per week
Then you have to devide the miles by how many gallons per gas you travle.
150/28 miles per gallon = 5.3571....
That how many gallons you'll need a week.
Now, you times the gallons by the price of the gas
5.3571... x $3.05 = $16.3392...
Finally you times the amoutn of money for a week time 4 weeks.
$16.3392... x 4 = $65.35 (to the two decimal mark)
Hope this helped you! : )

Answer:
This question is pretty simple, half the values given are just to confuse you
notice that we are given a function which gives us the height of the rock at any given time, so if we use that function for t=2 seconds, we will get the height of the rock after 2 seconds
We are given the function:
h(t) = -16t² - 50t + 220
replacing t with 2
h(2) = -16(2)² - 50(2) + 220
h(2) = -16(4) - 100 + 220
h(2) = -64 - 100 + 220
h(2) = 56 feet
Therefore, the height of the rock 2 seconds after throwing is 56 m

making it:
40% = 0.80
2.00 * 100%
A florist sells a dozen roses for $35.40. She sells individual roses for the same unit cost. Write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y. How much would 18 roses cost?
Answer: The equation is
The cost of 18 roses is 53.10.
Step-by-step explanation:
Given:
A florist sells a dozen roses for 35.40. She sells individual roses for the same unit price.
Now, to find the cost of 18 roses and write an equation to represent the relationship between the number of roses, x, and the total cost of the roses, y.
1 dozen = 12.
Now, to get the cost of 18 roses we use unitary method:
If 12 roses cost = 35.40.
So, 1 roses cost = 2.95.
Thus, 18 roses cost = 53.10.
Therefore, the cost of 18 roses = 53.10.
Now, to write an equation the relationship between the number of roses and the total cost of the roses:
Cost of per rose = 2.95.
As, given in question:
Number of roses =
Total cost of the roses =
Total cost of the roses = Cost of per rose × Number of roses.
So, the equation is:
Therefore, the equation is And the cost of 18 roses is 53.10.

Step-by-step explanation:
In 1998, the population of country C was 38 million, and the exponential growth rate was 1% per year
Answer:
Step-by-step explanation:
Formula for the exponential graph is given by the function,
[tex]P(t) = P_0(1 + r)^t[/tex]
Where [tex]P(t)[/tex] = population after 't' years
[tex]P_0[/tex] = Initial population
r = rate of increase
t = Number of years
In 1988, population of a country C was 30 million.
A). Function for the population will be,
[tex]P(t)=38(1+0.01)^t[/tex]
[tex]=38(1.01)^t[/tex]
B). Population in year 2020,
[tex]P(22)=38(1.01)^{22}[/tex]
= 47.30 million
C). Doubling time means the duration in which [tex]P_0[/tex] becomes [tex]2(P_0)[/tex].
[tex]P(t)=2P_0[/tex]
[tex]2P_0=P_0(1.01)^t[/tex]
[tex](1.01)^t=2[/tex]
By taking log on both the sides of the equation,
t[log(1.01)] = log2
t = [tex]\frac{\text{log}(2)}{\text{log}(1.01)}[/tex]
= [tex]\frac{0.30103}{0.004321}[/tex]
t = 69.66 years

The beginning balance of Keyshawn's savings account for the month of September was $3900, and it remained this way for the first 11 days of the month. On September 12, Keyshawn made a withdrawal of $700, so his balance changed, and it remained the same for a total of 9 days. On September 20, Keyshawn made a deposit of $1500, so his balance changed again, and it remained the same for a total of 10 days to finish out the month. Keyshawn's savings account has an APR of 3.65%, calculates interest daily, and pays interest at the end of the month. Keyshawn wants to calculate the amount he earned in interest during the month of September.

State how many imaginary and real zeros the function has.
f(x) = x^3 + 5x^2 + x + 5
0 imaginary; 3 real
1 imaginary; 2 real
3 imaginary; 0 real
2 imaginary; 1 real
Answer:
1 real root 2 imaginary roots
Step-by-step explanation:
f(x) = x^3 + 5x^2 + x + 5
Set equal to zero to find the zeros
0 = x^3 + 5x^2 + x + 5
Factor by grouping
0 = x^2( x+5) + 1( x+5)
0 = (x+5) ( x^2+1)
Using the zero product property
x+5 =0 x^2+1 =0
x=-5 x^2 = -1
x=-5 x = ±i
1 real root 2 imaginary roots
Answer:
1 real root 2 imaginary roots
Step-by-step explanation:
f(x) = x^3 + 5x^2 + x + 5
Set equal to zero to find the zeros
0 = x^3 + 5x^2 + x + 5
Factor by grouping
0 = x^2( x+5) + 1( x+5)
0 = (x+5) ( x^2+1)
Using the zero product property
x+5 =0 x^2+1 =0
x=-5 x^2 = -1
x=-5 x = ±i
1 real root 2 imaginary roots

PLEASE HELP AGAIN ?! stuck :(
Write a compound inequality for the graph shown below. Use z for your variable.
Answer:
wat happened to yoi
are u fine
plz help me will give brainlyest
Answer:
1. x = independent variable: Age
y = dependent variable: Accidents
2. Age scale and Accidents scale
The scale for age ranges from 15 - 30 with the value of 5 difference between each number.
While the accidents scale ranges from 0 -1 with no difference in between.
3. In my opinion, the scatter plot looks as though it decreases in accidents once the age rises. As seen from the data shown.
Step-by-step explanation:
1) x is considered as the independent variable, while y is considered the dependent value.
2) There are two sets of scales, one for the x and the other for y. These scales are the values that are interpreted in order to show data of the graph, due to their number and various size(s).
3) If you were to draw a line through the graph, you can somewhat create the image that the line would go down into the right corner! Meaning that it is decreasing over time.
