Answer:
I am pretty sure the answer would be B
Step-by-step explanation:
Im sorry if it is wrong
Let us set up a system of functions to describe the given situation and see if they ever intersect.
Elena has initially 15000 miles and adds 15000 per year.
we can describe it as Elena = 15000+15000(years).
Marc's equation can be given as = 24000+11000(years).
Setting both conditions equal, we get
15000+15000(years)=24000+11000(years).
Clubbing years on one side we get,
4000(years)=9000
Lets divide by 4000 on each side we get years = 2.25
Hence yes, the mileages will equal the same value (whatever it may be) in 2.25 years from the the beginning of the problem.
Answer:
-5
Step-by-step explanation:
-8 - -3 basically forget about the - just do the question 8 - 3 then u get 5 then add the - sign
Answer: (-6,-5)
Step-by-step explanation:
2x - 2y = -2 ............ equation 1
3x - y = -13 ................ equation 2
solving by substitution method
from equation 2 , make y the subject of the formula, we have
y = 3x + 13 .............. equation 3
substitute equation 3 into equation 1 , we have
2x - 2 (3x + 13 ) = -2
2x - 6x - 26 = -2
-4x - 26 = -2
-4x = -2 +26
-4x = 24
x = 24/-4
x = -6
substitute x = -6 into equation 3 to get the value of y , we have
y = 3(-6) + 13
y = -18 +13
y = -5
