Which of the following equations is not a linear equation?
(LOOK AT PHOTO!!!)
Answers
Answer:
I think that B is not a linear equation.
Step-by-step explanation:
Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.
I hope this helps! :)
[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Linear equation has a degree of 1, that means the maximum power of a variable in a linear equation/expression should be 1. if an equation doesn't satisfy this condition then it's not a linear equation.
So, by Observing the choices, we get to the conclusion that the one which isn't a linear equation is B
[tex]\qquad \sf \dashrightarrow \: {x}^{3} - 5 {y}^{2} = 4[/tex]
Here, the variables have greater powers tham one, and degree is 3. so it's the required Answer ~

In an AP* Stats class, 57% of students eat breakfast in the morning and 80% of students floss their teeth. Forty-six percent of students eat breakfast and also floss their teeth. What is the probability that a student from this class eats breakfast but does not floss their teeth
Answers
Answer:
The probability that a student from this class eats breakfast but does not floss their teeth is .11 (11%).
Step-by-step explanation:
Let's start by making a two-way table (you can also make a tree diagram).
Let's make the total number of students = 100. Now, fill out the table using the given probabilities from the question.
We are given that 57% of students eat breakfast in the morning, so the total in the "Eats breakfast" column is 57.
80% of the students floss their teeth, so the total in the "Flosses teeth" row is 80.
We can fill out the rest of the table using simple algebra and the fact that the probabilities must add up to 1.
I've attached a table that I created showing what the two-way table should look like when filled out completely.
Now, we want to find the probability that a student eats breakfast but does not floss their teeth.
We can look at the column "Eats breakfast" and the row "Does not floss teeth" and see that 11 (out of 100) students eat breakfast without flossing their teeth.
Therefore, the probability that a student from this class eats breakfast without flossing their teeth is .11.

what is intercept: intercept simply means a point on the y axis through which a slope passes and also in the equation you were given y = mx + c I mean y = 2x -2 the c is the intercept meaning -2 .
so wherever that straight line meets with with y axis the number at that very point is your intercept.
the y intercept for the first one is -2
and it's "less than" since it's a negative number.

The answer is 35.5 square units
Step-by-step explanation:
The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner.
We get this formula:
A(shape) = A(rectangle) - A(small triangle) + A(big triangle)
SO LET'S FIND EACH!
A(rectangle)= length x width
length= 8 units
width= 4 units
We get:
A(rectangle) =8x4= 32 square unit
A(small triangle)= (base x height)/2
base= 1 unit
height= 1 unit
We get:
A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units
A(big triangle)= (base x height)/2
base= 2 units
height= 4units
We get:
A(big triangle)= (2x4)/2 = 8/2 = 4 square units
For the final result:
A(shape) = 32 - 0.5 + 4 = 35.5 square units

Answers
Answer:
x = 39
Step-by-step explanation:
all triangles have angle measures that add up to 180°.
This means that to find what x is, you add 102 and 39, and then subtract that from 180, so
180-(102+39) = x
180-141=x
39=x
Answer:
x° = 39°
Step-by-step explanation:
According to the angle sum property of triangles, the 3 angles in a triangle will sum up to 180°.
102° + 39° + x° = 180°
141° + x° = 180°
x° = 180° - 141°
x° = 39°

A solution to -x + 10 = 2x + 4 is 8
Answers
Answer:
False.
Step-by-step explanation:
What is the question if you have the solution already?
I guess its a true/false question. In that case it's false because:
-x + 10 = 2x + 4
-x -2x + 10 = 4
-x - 2x = 4 - 10
-3x = -6
x = - 6 / -3
x = 2
Answer:
False.
This equation has only one solution, and it is x = 2.
Step-by-step explanation:
-x + 10 = 2x + 4
Subtract 2x from both sides.
-3x + 10 = 4
Subtract 10 from both sides.
-3x = -6
Divide both sides by -3.
x = 2

What is the value of x is the solution to the equation -8(x + 3) = -10x - 5?
Answers
Answer:
x = 19/2
Step-by-step explanation:
1) Distribute
-8x-24=-10x-5
2) Add 24 to both sides
-8x-24+24=-10x-5+24
3) Simplify
- Add the numbers
-8x = -10x - 5 + 24
- Add the numbers
-8x = -10x+19
4) Add 10x to both sides
-8x+10x=-10x+19+10x
5) Simplify
- Combine like terms
2x = -10x+19+10x
-Combine like terms
2x=19
6) Divide both sides by the same factor
2x/2 = 19/2
7) Simplify
- Cancel terms that are in both the numerator and denominator
x = 19/2
