Answer:
y = 5x + 92
y = 9x + 27
Step-by-step explanation:
Slope intercept form is written as y = mx + b, and you know that y represents "quects" and x represents months.
For farmer Rew, b would be 92 because that is how many "quects" he started off with. m would be 5 because that is how many new "quects" he gets every month. (y = 5x + 92)
For farmer Joogh, b would be 27 because she started off with 27 "quects." m would be 9 because she gets 9 new "quects" every month. (y = 9x + 27)
Ivan has $50,000 in a savings account that earns 4% interest per year. The interest is not compounded. To the nearest dollar, how much interest will he earn in 5 years?
Answer:
$2,000

Ryan's rate of change is ________ Taylor's rate of change .
Ryan'sstaring balanced is_______ Taylor's starting balanced.
We want to compare the rates of change and starting balances of Ryan and Taylor, the correct answers are:
"Ryan's rate of change is _less than_ Taylor's rate of change.""Ryan's starting balance is greater than Taylor's starting balance."So we know that Ryan's savings plan can be modeled by:
S(m) = 15*m + 50.
This means that he starts with 50, and saves 15 per month, then:
Ryan's rate of change = 15 per monthRyan's initial balance = 50For Taylor we have a table:
month amount saved:
0 25
1 45
2 65
3 85
So, in month 0 he has 25, thus, his initial balance is 25.
And each month the amount saved increases by 20, then the equation is:
T(m) = 20*m + 25
Then we have:
Taylor's rate of change = 20 per month.Taylor's initial balance = 25Now we can see that:
"Ryan's rate of change is _less than_ Taylor's rate of change."
"Ryan's starting balance is greater than Taylor's starting balanced."

If cost of 15 eggs is ? 75, then find out the cost of 4 dozens eggs.
Answer:
Each egg is $5 so 4 dozen(48) is $240
Step-by-step explanation:
the way to do this is 75/15= 5
and then you multiply 12 x 4 to get 48 eggs
and then multiply 48 x 5 to get $240
15:75
divide each by 5
3:15
(4 dozen is 48 -> 48/3 = 16)
multiply each by 16

which of the following is parallel to the line y=3/4x+7
y=-4/3x+7
y=-3/4x+7
Are you sure you wrote the question corrcetly?
For something to be parallel their slopes have to be equal but their y-intercepts need to be different.
since your equation equals y=3/4x+7 that would mean that 3/4 is the slope.
so an answer with a slope of 3/4x and a y-intercept not equal to 7 would be the correct answer.
r is equal to the sum of twenty-one and y *
Answer:
r=21+y
Step-by-step explanation:
its telling you that r is going to be equal to the rest of the equation, so we start with
r=
then, it mentions the sum of 21 and y, so this would be represented as
21+y
since r is equal to the sum of 21 and y, your answer is
r=21+y
(because of comutitive property, r=y+21 is also an acceptable answer.)
