I believe that Q is fourths? And Y is Yard.
It is: i √6 i believe :))
Answer: C
Explanation: Let's find each equation without any inequalities first. We have a dotted line at y = 1, so we can already remove A and B. Now, a dotted line represents exclusivity and hence; it should not include the = sign.
Thus, by elimination, the answer must be C.
Answer:
x=3 and y=6
Step-by-step explanation:
Substitute: y=2x in place of Y in the first equation we will put 2x
x+2x= 9
1x+2x=9
3x=9
divide both sides by 3
x=3
Now go to either of the original equations and substitute the answer you got for x which is 3 to find y
y=2x so 2 times 3 = so y =6
Answer:
$125,000.12 last year
$375,000.36 this year
Step-by-step explanation:
Last year, her profits were x.
This year, the profits are three times greater, so they are 3x.
Altogether for both years, the profits are x + 3x = 4x.
The profits for both years combined are $500,000.48
4x = 500,000.48
Divide both sides by 4.
x = 500,000.48/4
x = 125,000.12
The profits last year were $125,000.12
This year, the profits were 3x = 3(125,000.12) = 375,000.36, or $375,000.36
