3/ If f(x) = 2x -5 Find f(x-1)=
Explanation: Here we have function f(x) = 2x - 5
and we're asked to find f(x - 1).
Don't be thrown off if you're asked to plus a variable into a function.
If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.
Remember to use parenthses when substituting into a function.
So simplifying on the right side, we would distribute the 2
through the parenthses and we have 2x -2 - 5.
Now combining like terms, we have 2x - 7
Explain how to solve 5d = 35
Answer:
D=7
Step-by-step explanation:
SO isolate the variable y dividing 5 on both sides
d=7
Answer: d = 7
Step-by-step explanation:
5d = 35
You have to divide both sides by 5 since we need to isolate the variable 'd' to figure out what d is.
5d ÷ 5 = d
35 ÷ 5 = 7
So d = 7

Airline fares for a flight from Dallas to Austin are $30 for first class and $25 for tourist class. If a flight had 52 passengers who paid $1360, how many first class and tourist class passengers were there?
There were 40 tourist class passengers and 12 first class passengers.
Explanation:
Let the number of passengers who booked for tourist class be

K/-3 + 3 =-2
Find the estimate of k
Answer:
K= 15
Step-by-step explanation:
K/-3 +3 = -2
Simplify by subtracting 3 on each side:
K/-3 = -2-3
K/-3 = -5
Simplify further by multiplying each side by -3:
K= -5*-3
K = 15

ABCD is a parallelogram, find the value of y
Answer:
33
Step-by-step explanation:
angles A and B should add up to 180, so A must be 40, and because it is a parallelogram the anlge across from it should also equal 40. 33+7=40.
Write a linear function f with the given values. f(6)=-2, f(0)=-5
Answer:
y = 0.5m - 5
Step-by-step explanation:
the equation of a line can be written as
y = mx + b, with x being the input and y the output
let's plug in our two values.
-2 = m(6) + b
-2 = 6m + b
-5 = 0m + b
-2 = 6m+b
-5 = b
plug -5=b into the first equation
-2 = 6m - 5
add 5 to both sides
3 = 6m
divide both sides by 6
0.5 = m
our function is now
y = 0.5m - 5

Calvin is comparing the growth of two plants. Plant A started at a height of four inches and grows two inches each month. Plant B grew according to this equation, h = 4m + 2, where h, is the height after m, months. At what month will the two plants be the same height?
Answer:
After 1 month, they will have same heights.
Step-by-step explanation:
Calvin is comparing the growth of two plants.
Plant A started at a height of four inches and grows two inches each month.
h'=4+2m
where
h' is height of plant after m months.
Plant B grew according to this equation, h = 4m + 2, where h, is the height after m, months.
We need to find at what month the plants have the same height. ATQ.
h = h'
4+2m = 4m + 2
Taking like terms together,
4-2 = 4m-2m
2=2m
m = 1
Hence, after 1 month, the plants will have same height.
Garrett arrived at the train station at 12:35 P.M. His train finally came at 1:30 P.M. How long
did Garrett have to wait for the train?
Answer:
55 minutes
Step-by-step explanation
He started waiting at 12:35 P.M. If we're assuming this is the same day, you're able to add the minutes until you get to 1:00 P.M., which is around 25 minutes. Afterwards, you need to add another 30 minutes to get to the train's time of arrival, which means you should get 55 minutes!
