2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: 4x - 3y and x + 2y = 10.
Answer:
0.09 or 9%
Step-by-step explanation:
Formula:
I = Prt
r = I/(Pt)
Given:
I = 1350
P = 5000
t = 3
Finding r:
r = I/(Pt)
r = 1350/(5000 x 3)
r = 1350/15000
r = 0.09
0.09 or 9%
<u>Given</u>:
The given function 
which models the value of Mark’s car, where x represents the number of years since he purchased the car.
We need to determine the approximate value of Mark's car after 7 years.
<u>Value of the car:</u>
The value of the car after 7 years can be determined by substituting x = 7 in the function , we get;
Rounding off to the nearest dollar, we get;
Thus, the approximate value of Mark's car after 7 years is $14278.
Hence, Option a is the correct answer.
Answer:
the last one
Step-by-step explanation:
Answer: Since 3−5+2=0, then 2
is the additive inverse of 3−5 is 2
Since 5−3−2=0, then −2is the additive inverse of 5−3. is -2
Step-by-step explanation: additive inverse
The additive inverse of any number
x
is the number that gives zero when added to
x
. Example: the additive inverse of
5 is −5.
