The first thing we must do for this case is to define a variable.
We have then:
n: unknown number.
We write the algebraic expression:
13 - 4n
For n = 3 we have:
13 - 4 (3) = 13 - 12 = 1
Answer:
An expression that represents this phrase is:
13 - 4n
its value if n = 3 is:
1
Answer:
-288
Step-by-step explanation: I took the following steps to find the answer:
(4 + 32)(15 – 23)
\ /
(36)(15 – 23)
\ /
(36) (- 8)
\ /
-288
In order to find the y-intercept, replace x by 0.
So, for first option:
f(0) = 7(1) - 2 = 5
For second option:
f(0) = -3(1) - 5 = -8
For third option:
f(0) = 5(1)-1=4
For Fourth option:
f(0) = -5(1) + 10 = 5
For Fifth Option:
f(0) = 2(1) + 5 = 7
So, option 1 and 4 have the y-intercept (0,5)
Answer:
14x4=total students
Step-by-step explanation:
Because if 14 children is one fourth then you must multiply 14 times 4 to get the total.
Have a most wonderfull day and a good year! I hope you like the answer given.
1st side = x
2nd side = 2x
3rd side is x-5
so x +2x + x-5 = 31
answer is A
