Answer: You can multiply the top equation by -1 to eliminate the x variable.
And the solution is (2,4/3) in case you need it.
Step-by-step explanation:
2x + 3y = 8
2x + 6y = 12
If you multiply the upper equation or down equation by one, you will be able to eliminate the x variable.
-1( 2x + 3y) = -1(8) New equation: -2x -3y = -8.
Add the new equation you got by multiplying the top equation by -1 to the bottom equation.
Add them: -2x -3y = -8
2x + 6y = 12
3y = 4
y = 4/3
You can now input the value for y into the one of the equations and solve for x.
-2x - 3(4/3) = -8
-2x -4 = -8
+4 +4
-2x = -4
x = 2
Answer: $ 532
Step-by-step explanation:
Given: Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales.
She sold $600 in clothing on Saturday and $1200 in clothing on Sunday.
To find : Earning in two days.
Total sales she did in 2 days = $600+$1200 = $1800
Then, her total earning for 2 days = 2 x( Base salary)+ 14% of (Total sales)
= 2 x ($140) + (0.14) ($1800)
= $(280+252)
= $ 532
Hence, she earned $ 532 over the 2 days.
Hey!

This just shows to substitute all of x with -1.
g(-1) = 3(-1) - 5
g(-1) = -3 - 5
g(-1) = -8
-------------------------------------------------
Hence, the answer is -8!

Answer:
Step-by-step explanation:
The formula representing the the annual inflation rate r is expressed as
r = (F/P)1/n−1
Where
n represents the the number of years during which the value increases from P to F
A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. This means that
P = $800,000
F = $1,100,000
n = 6
Therefore,
r = (1100000/800000)1/6−1
r = 1.375/5 = 0.275
