Which conic section is represented by the following equation? 3x2 – 7x 8y2 – 2y 1 = 0 circle ellipse parabola hyperbola.
Answers
The conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.
How to identify the type of conic section from an equation?To of identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,
[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]
In this equation, if,
[tex]A\neq B[/tex]
Then it is the equation of circle.
If In this equation,
[tex]A\neq B[/tex]
But both A and B has same sign (either positive or negative) then it is the equation of ellipse.
The given equation in the problem is,
[tex]3x^2 - 7x+ 8y^2 - 2y+ 1 = 0[/tex]
Here, in the equation,
[tex]A=3\\B=8[/tex]
The A is not equal to B but the sign of both are positive. Hence this equation is the equation of ellipse.
Hence, the conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.

Zoe filed for bankruptcy several years ago and now wants to take out a loan for $15,200. since zoe has a past bankruptcy, she will end up paying a higher interest rate. the loan term is four years, and her payments are $819.20 per month. with a better credit rating, her payments could have been $440.82 per month. how much more in interest will zoe end up paying for her loan because of her bankruptcy? a. $4,540.56 b. $15,135.20 c. $23,346.24 d. $18,162.24
Answers
Answer:
18,162.24 / D
Step-by-step explanation:
12 months per year times 4 years is 48 months
819.20 x 48 = 39,321.60 which is what she is paying
440.82 x 42 = 21,159.36 which is what she could be paying
so do 39321.60 - 21159.36 to get 18,162.24 or answer D.

In one day, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda. Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk. Marian consumes 510 calories by drinking 3 servings of milk and 1 soda. Using matrices to solve, how many calories are in 1 serving of milk?
A. 90
B. 110
C. 130
D. 180
Answers
Answer:
the answer is B on ed2020
Step-by-step explanation:
for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.
so you have soda = 180 cal and juice = 130 cal
if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct
Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories
How to solve Linear Programming problems?
Let the calories in one serving of milk be x
Let the calories in one serving of juice be y
Let the calories in one serving of soda be z
Thus, for Joe, equation to show amount of calories is;;
2x + y + z = 530 -----(1)
For Darius, equation to show amount of calories is; ;
x + 2y = 370 ------(2)
For Marian, equation to show amount of calories is;
3x + z = 510 ------(3)
Using matrix calculator online to calculate this 3 equations, we have;
x = 110 calories.

Answer: 6x+3y=12
x=-1/2y+2
Step-by-step explanation:
step 1: add -3y to both sides
6x+3y+-3y=12+-3y
6x=-3y+12
step 2: divide both sides by 6
6x/6=-3y+12/6
Answer:
y = 6 and x = -1.
Step-by-step explanation:
It's normally useful for me to rewrite the equation so they match. I'm using the substitution method.
First find out what "y" equals (I'm using the second equation):
Add 8 to both sides:
y - 8 = 2x
+8 +8
y = 2x + 8
Plug this into the previous equation.
6x + 3(2x + 8) = 12
Distribute first:
3(2x + 8)
3 * 2x = 6x
3 * 8 = 24
6x + 24
Rewrite the equation:
6x + 6x + 24 = 12
Find liked terms.
6x + 6x + 24 = 12
They are liked terms so combined them: 6x + 6x = 12x.
Rewrite the equation again:
12x + 24 = 12
Solve for "x".
Subtract 24 on both sides.
12x + 24 = 12
-24 -24
12x = -12
Divide 12 to get x by itself.
12x = -12
12
x = -1
Plug x into the second equation to find y.
y - 8 = 2(-1)
y - 8 = -2
Add 8 to both sides.
y - 8 = -2
+8 +8
y = 6
The answers are y = 6 and x = -1.

True or false: Outliers can cause data sets to be skewed.
Answers
Answer:
True
Step-by-step explanation:
Firstly, the definition of an outlier is a number farther away from the general populous of digits. For example, a number line can have a lot of numbers clustered at 2, 3, and 4 but might have one way over on 10. This would mean 10 is an outlier.Secondly, a skew is when a dot plot or a box and whisker plot is shaped a certain way. A negative skew would be a graph sloping to the right, and a positive skew is a graph sloping to the left. It looks a bit like a hill.Knowing that the shape is made up of the different numbers and their amount, we can conclude that an outlier, or a number that is stretched far from the others, would affect the data set.This means that the skew might change if there is a variable that is out of place.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
