Can somebody please help me with my math ?
Step-by-step explanation:
just plug in the numbers to the x values
if f(3) then ur equation would look like this f(3) = 4x - 5
then u solve it to get the answer.
3 = 4x - 5
+ 5 = 4x + 5
------------------ ---> add 5 on both sides
8 = 4x
now u just divide. 8 ÷ 4 = 2 so f(3) = 2

if Richard worked for 7 dollars and made 9 dollars and hour how much would he make?
Answer:
$63
Step-by-step explanation:
I believe you meant Richard worked for 7 hours and made $9 per hour.
In order to know how much Richard earned for 7 hours, you have to multiply Richard's salary rate with his number of working hours.
7 hours x 9 dollars/hour = $63Therefore, Richard earned $63 for his 7-hour work.
Additional Information
Another example is: if Richard worked for 10 hours, you just have to multiply his salary rate again to his number of working hours.
10 hours x 9 dollars/hour = $90what is the value of y=4x-6 when x=5?

If I is || m, find the value of y.
A. 50
B. 5
C. 27
D. 10
Answer:
D. 10
Step-by-step explanation:
8x-14=5x+34
8x-5x=34+14
3x=48
x=48/3
x=16
8x-14+5y+16 = 180
8(16)-14+5y+16 = 180
128-14+5y+16=180
5y=180-128-16+14
5y=50
Y = 10

For a school project, Brian counts the cars every weekday after to school to determine how many are silver. He records his findings
in this table. What is the experimental probability that the next car he sees will be silver?
A 1/2
B 1/3
C 1/4
D 1/5
A)
B)
C)
D
Answer:
The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.

Write a rule for the nth term of the arithmetic sequence described below.
A5 =
91 and a20 =
1
an=
A25=
Answer:
an = 115 + (n - 1) (-6)
a25 = - 29
Step-by-step explanation:
We use the definition for the nth term of an arithmetic sequence:
an = a1 + (n - 1) d
a5 = 91 = a1 + (5 - 1) d
91 = a1 + 4 d
a20 = 1 = a1 + (20 - 1) d = a1 + 19 d
1 = a1 + 19 d
now we subtract term by term one expression from the other
90 = 4 d - 19 d
90 = - 15 d
divide both sides by -15 to isolate d
d = 90 / (-15) = -6
Now we can calculate what a1 is using for example:
1 = a1 + 19 d
1 = a1 - 114
add 114 to both sides:
115 = a1
Then our general expression for the sequence is:
an = 115 + (n - 1) (-6)
We can now use it to calculate the value of a25:
a25 = 115 + (24) * (-6) = -29
