Answer:
y = 3x +5
Step-by-step explanation:
Maybe you want the equation of the line with slope 3 through point (-2, -1).
The point-slope form of the equation of a line is useful for this:
y -k = m(x -h) . . . . line with slope m through point (h, k)
y +1 = 3(x +2) . . . . the equation with your point and slope
y = 3x +5 . . . . . . . rearranged to slope-intercept form
Megan bought 2 1/4 pounds of bananas for 0.80 per pound and 1 1/2 pounds of strawberries for 1.10 per pound how much more did Megan spend on bananas than on strawberries express the answer as dollars. Cents
Answer:
$0.15
Step-by-step explanation:
Given that:
Cost of banana per pound = $0.80
Amount of banana bought = [tex]2\frac{1}{4}=2.25\ pounds[/tex]
Cost of strawberries per pound = $1.10
Amount of strawberries bought = [tex]1\frac{1}{2} = 1.5\ pounds[/tex]
To find:
How much more money was spent on bananas than Strawberries.
Solution:
Here, first we need to find how much money was spent on bananas and strawberries.
Then we need to subtract the smaller value from larger value.
From the given values, we can calculate the following:
Cost of banana for 2.25 pounds = $0.80 [tex]\times[/tex] 2.25 = $1.8
Similarly,
Cost of strawberries for 1.5 pounds = $1.10 [tex]\times[/tex] 1.5 = $1.65
Money more spent on bananas = $1.8 - $1.65 = $0.15

Answer:
1. asymptotes: x=-6, x=6, y=0; zero: x=0
2. 20 blue fish
Step-by-step explanation:
1. The vertical asymptotes are where the denominator is zero. It factors as (x-6)(x+6), so will have zeros at x=-6 and x=6.
The horizontal asymptote is at the limit when x goes to infinity. Here, the ratio of highest-degree terms is 6/x, so the value goes to zero as x gets large.
The zero is where the numerator is zero, at x=0.
In summary:
vertical asymptotes: x = ±6horizontal asymptote: y = 0zero: (0, 0)__
2. 60% are red, so 40% are blue. The difference in percentages is 60%-40% = 20%. The percentage of blue fish (40%) is twice the difference (=2×20%), so the number of blue fish is twice the difference in numbers.
blue fish = 2×10 = 20 fish
Check
There are then 20+10=30 red fish, so 20+30=50 fish total. Reds are 30/50 = 60% of the total.
Additional comment
I find it often works well to work with ratios, which I can often do in my head. Other folks like to see equations. Here, we could write equations like ...
r = 60%(r + b) . . . . reds are 60% of the total
r - b = 10 . . . . . . . . 10 more reds than blues
We want the value of b, so we can eliminate r by substituting for it:
r = 10 + b . . . . from the second equation above
(10 +b) = 0.60((10 +b) + b) . . . . substitute for r
10 +b = 6 + 1.2b . . . simplify
4 = 0.2b . . . . subtract b+6
20 = b . . . . . . multiply by 5 (there are 20 blue fish)

A student's parents offer him one of two options to receive scholarship money for college.
Option A: Deposit $17,000.00 into his savings account and then add an additional $1,250.00 each day for 30 days
or
Option B: Deposit $0.50 into his savings account and then triple that amount each day for only 10 days
When rounded to the nearest cent, how much money is deposited into his savings account on the last day (day 30) for Option A, and how much is deposited into his savings account on the last day (day 10) for Option B? If the student keeps only what is deposited on the last day, which option should he choose?
Option A Versus Option B
Option A Option B
Day Amount Deposited Day Amount Deposited
0 $17,000.00 0 $0.50
1 $18,250.00 1 $1.50
2 $19,500.00 2 $4.50
A = $142,845.76, B = $29,524.50; B, because he receives $113,321.26 more
A = $54,500.00, B = $10.50; A, because he receives $54,489.50 more
A = $37,500.00, B = $59,049.00; B, because he receives $21,549.00 more
A = $54,500.00, B = $29,524.50; A, because he receives $24,975.50 more
Answer:
option a
Step-by-step explanation:
it is because $17,000.00 will make you have more money and have better things to do in the nearest future
The amount received by student in option A and B are A = $54,500.00, B = $29,524.50, Option A is better because student receives $24,975.50 more.
What is Simplification?Simplification in mathematical terms is a process to convert a long mathematical expression in simple and easy form.
(A)
Given that,
Amount deposit by student in starting = $17,000
Also, student add $1250 each day for 30 days,
Amount added in 30 days = 1250 x 30 = $37500
Total amount in account = 17000 + 37500 = 54500
The final amount in account is $54500.
(B)
Amount deposited into saving account = $0.50
Also, student triple that amount for 10 days,
Amount in account in 10 days = 0.50 x 3¹⁰ = 29524.5
Option A is a better deal because the student receives $24,975.50 more.

WILL MARK BRAINLIEST Every month Jordan puts $14 into her bank account. Her grandma puts additional money into Jordan's bank account every month. After 12 months, Jordan has $216 in her bank account. How much did Jordan's grandma put into the account each month?
Jordan puts 14 per month for 12 months:
14 x 12 = 168 total.
Subtract the amount Jordan put in from the total:
216 - 168 = 48
Her grandma put a total of 48 in the bank. Divide that by 12 months:
48/12 = 4
Her grandma put $4 per month in the bank.
Answer:
The answer is his grandma puts $4 in per month.
Step-by-step explanation:
Take 14 and multiply it buy how many months are in a year. That equals 168. take 216 minus 168. That's 48. Divide 48 by 12 and that gets you 4. I hope this helps!

Step-by-step explanation:
All of the angles in a triangle add up to 180. So 180- (44+68)= 68. The third side of the triangle on the left is 68 degrees. The third side is a linear pair with the side in the opposite triangle which has a measure of 180-68=(112). Which leaves x=43

Rosetta owns a wedding photography business. For each wedding, she charges $100 plus $50 per hour of work. A linear equation that expresses the total amount of money Rosetta earns per wedding is y= 50x+100. What are the independent and dependent variables? What is the y-intercept and the slope?
a. The independent variable (z) is the amount of time Rosetta shoots photos. The dependent variable (y) is the amount, in dollars, Rosetta earns for a wedding.
b. Rosetta charges a one-time fee of $100 (this is when 2-0), so the y-intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50.
c. The independent variable (x) is the amount in dollars, Rosetta earns for a wedding. The dependent variable (y) is the amount of time Rosetta shoots photos.
d. Rosetta charges a one-time fee of $100 (this is when : 0), so they intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50.
e. The independent variable(x) is the amount of time Rosetta shoots photos.
The options are not clear enough, so i have attached it.
Answer:
A: The independent variable (x) is the amount of time Rosetta shoots photos. The dependent variable (y) is the amount, in dollars, Rosetta earns for a wedding.
Rosetta charges a one-time fee of $100 (this is when x = 0), so the y-intercept is 100. Rosetta earns $50 for each hour she works, so the slope is 50
Step-by-step explanation:
We are given the equation of total amount of money Rosetta earns per wedding as;
y = 50x + 100
Where x is number of hours.
Now, the independent variable will be x because it doesn't depend on any other variable whereas the dependent variable will be y because it depends on how many hours which is x.
Now, the y-intercept occurs when x = 0.
Thus;
y = 50(0) + 100
y = 100
Thus,she charges a one time fee of $100, so the y-intercept = $100 at x = 0.
From slope intercept equation which is;
y = mx + c and comparing with y = 50x + 100, where m is the slope, we can see that m = 50.
Thus, since she earns $50 per hour, the slope is 50.
The correct option is Option A.

2X -3 =12 what is the answer
Answer:
Step-by-step explanation:
2x-3= 12
+3 +3
2x = 15
/2 /2
x= 7.5
Answer:
x = 7.5
Step-by-step explanation:
So the equation looks like this:
2X -3 =12
So we are first going to get rid of -3 by adding 3 to both sides of the equal sign:
2X -3 = 12
+ 3 +3
SO the equation looks like this now:
2x = 15
Now we are going to segregate the variable x by dividing 2x and 15 by 2:
2x/2 = 15/2
x = 7.5
So in order to check our work we are going to substitute 7.5 where the x variable is in the equation:
2X -3 =12 or 2(7.5) - 3 = 12
2(7.5) - 3 = 12
15 - 3 = 12
12 = 12
So our answer to what the variable x equals is 7.5.
I hope this helps you!!
