Answer:
-28=7(x-7)
First expand the terms on the right side
That is
-28 = 7x - 49
Group like terms
7x = -28 + 49
7x = 21
Divide both sides by 7
7x/7 = 21 /7
x = 3
Hope this helps
Answer:
so x=3
Step-by-step explanation:
-28=7(x-7)
opening the brackets by multiplying
-28=7x-49
adding 49 on both sides
-28+49=7x-49+49
21=7x
dividing 7 on both sides
21/7=7x/7
x=3
i hope this will help you :)
The expression for the inequality is written as a > 200.
When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that each day, the cafeteria serves more than 200 apples with lunch.
The inequality will be written as,
a > 200

Answer:
d. physical features and locations tell historians about the ways people lived.
Step-by-step explanation:
I believe this is the correct answer
Answer:
a= domain = 3x range = 21-3 = 18
b= $200 As 0(B) = Point of origin balance = midway to $400
= 0 < 200 > 400 = midway 200.
c=function notation = 3x -3x + 6 = 21 we change the 3x to cancel out any balance.
d= 4th segment shows day 12 to day 15 across the x axis.
ok we see and count after reading this it has 21 days in total approx and 12th day it shows the function went to 12 days.
We can write F(x) = 12x+6 to equal the change in value then we need to distribute 12 x = 6
Which is the same as 9 days money = 6 days money
As 3 days was made reference to day 12- day 15 where she had zero in account. We can minus - 3 also to represent her last savings before adding the balance of 6.
ok no interest the maximum was $400 the zero y intercept (0.0)= $200
This makes everything so easy now.
We count 21 days = 21 this is what we will end with
Let 4 be x
4x -3 + 6
We count 5 change $ values 0, 1 , 2, 3, 4 on the graph and also 4 in repeat which makes the 400.
or could mean she started with 400 and the rest is interest. Now we know this we cna start writing a domain and i will keep this open and edit and try work this out for you.
Step-by-step explanation:
The last step for question one is converting 12 into 12
This means 4x = 3 so we change it to
3x -3 +6 = 21
Then you now can recognize and accept x = 4
Answer:
(a)
Domain: 0 to 21
Range: 0 to 400
(b)
B(0) = 200.
(c)
B(12) = 0
(d)
Segment 4. The value of B(d) in Segment 4 is 0.
Step-by-step explanation:
(a) The domain is the number of days. The range is the amount of money which is the number of dollars. The account was open for 3 weeks, and the graph shows the entire 3 weeks. 3 weeks = 21 days; the highest amount of money was $400.
Domain: 0 to 21
Range: 0 to 400
(b) B(0) is very close to half of the maximum value of B(d). Since the maximum value of B(d) = 400, B(0) = 200. B(0) means the value of the function at time 0. The account was opened with an initial deposit at time = 0. B(0) is the value of the account at time = 0 which is the initial deposit made to open the account.
(c)
B(12) = 0
(d)
There are 6 segments:
Segment 1: B(d) goes from $200 to $400.
Segment 2: B(d) remains at $400.
Segment 3: B(d) goes from $400 to $0.
Segment 4: B(D) remains at $0.
Segment 5: B(d) goes from $0 to $100.
Segment 6: B(d) goes from $100 to $300.
In Segment 4, the value of B(d) is 0, so Segment 4 represents days 12 through 15.
Answer:
27
Step-by-step explanation:
Simple interest is given by
I = Prt where I is the interest, P is the principle, r is the rate and t is the time
I = 300 * .03 * 3
I =27
27 dollars is made in interest
Answer: $27
Step-by-step explanation:
First you need to find 3% of 300 in order to find the annual interest.
3% = 0.03
300 * 0.03 = 9
The annual interest is $9. Now you need to multiply that by 3 to find the interest in 3 years.
9 * 3 = 27
The interest for 3 years is $27.
