Answer:
85 degrees
Step-by-step explanation:
To start we can call the angle x and make an equation.
The complement of the angle would be 90 degrees - x
The supplement of the angle would be 180 degrees - x
Therefore, the difference between the measures of its supplement and nine times its complement is
180 - x - 9(90 - x) = 50
Solving,
180 - x - 810 + 9x = 50
8x - 630 = 50
8x = 680
x = 85 degrees.

Answer:
Step-by-step explanation:
f(n)= 3n+2
hence
1) for n= -2
f(-2) = 3(-2)+2 =-6+2= -4
2) for n= -1
f(-1) = 3(-1)+2 =-1
3) for n=0
f(0)=3(0)+2 = 2
4) for n=1
f(1) =3(1)+2 =5
5) for n=2
f(2)=3(2)+2 =8
Hence "C" option is correct

Simplify sin^2y/sec^2 y−1 to a single trigonometric function
Answer:
[tex] \frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y[/tex]
Step-by-step explanation:
We know that [tex] { \tan }^{2} y = { \sec }^{2} y - 1[/tex]
Also , [tex] { \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y } [/tex]
So ,
[tex] \frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y[/tex]

Cory and Everett have collected model cars since the third grade. Cory has 80 model cars in his collection, which is 25% more than Everette has. How many model cars does Everette have?
Answer:
64 model cars.
Step-by-step explanation:
What we know.
Cory has 80 cars in his collection.
That is 25% more than Everett has.
We can deduce that the equation would be c = 1.25e.
So, how do we figure out e?
Well, 1.25 is the same as 5/4.
So, find the reciprocal of 5/4 and multiply by 80.
4/5 * 80 = e
64 = e
Everett has 64 model cars in his collection

HELP ME PLEASE!!! this dosent make sense
Answer:
I think it would be D not sure tho hope this is helpful
Answer:
B
Step-by-step explanation:
The correct answer is B because in A and C, the gray area is not under the blue line since y has to be less than the equation. It is not D because the equation does not have a negative slope and in this inequality, it is also not equal to. Because the line in D is not a dotted line, then you know it is also equal to.

The length of a garden is 5 feet greater than 2 times the width. The perimeter of the garden is 76 feet. What are the length and width of the garden?
Answer:
length is 32 and width is 6
Step-by-step explanation:
12w + 4 = 76
12w = 72
w = 6
6 time 5 is 30 plus 2 is 32

h = 21
Step-by-step explanation:
10h + 15 = 225
10h + 15 - 15 = 225 - 15
10h = 210
10 ÷ 10h = 210 ÷ 10
h = 21
— 3 + 5 + 6g = 11 – 3g
Given : −3 + 5 + 6g = 11 − 3g
To find : The variable g
Solution:
Isolate and solve for the variable g in the equation −3 + 5 + 6g = 11 − 3g
Steps:
−3 + 5 + 6g = 11 − 3g
2 + 6g = 11 − 3g
6g = −3g + 9
9g = 9
g = 1
Hence,
Answer: g = 1

Answer:
4x + 8
Step-by-step explanation:
1. 4(2x + 4) Multiply 2x by 4 to get 8x. Multiply 4 by 4 to get 16. You should now have the equation 8x + 16 / 2.
2. Divide the 8x and 16 by 2. You should get 4x and 8. (4x + 8).

Express (x+8)squared as a trinomial in standard form
Step-by-step explanation:
(x + 8)²
= (x + 8)(x + 8)
= x² + 2(x)(8) + 8²
= x² + 16x + 64.
The binomial expression (x + 8)² is converted into trinomial in standard form x² + 16x + 64.
What is a polynomial?A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear . Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear:
Answer:
The equations are not given but the clue to your answer is given below:
Step-by-step explanation:
So the question above talks generally about differential equations (equations whose derivatives can be found) and then describes them thus - the order of a differential equation and the linearity status of a differential equation.
To determine whether or not each of the absent equations is linear, check for the following characteristics of linearity:
1. The maximum number or power that any variable in a linear equation is raised to is 1.
Example: 2x² + 6y = 43y is NOT a linear equation because some or all (in this case, variable x) of the variables in it are raised to a power greater than 1. Variable x is raised to the power of 2.
2. An equation (a linear equation, in this case) contains an 'equal to' sign. This is the reason why it's called an equation. There is a mathematical expression on each side of the equal to sign. Take note of this, just incase one of the options in your question has no equal to sign.
Example: 2x + 6y is NOT a linear equation. It is a linear expression. It contains no equal to sign that compares two distinct mathematical expressions.
3. A linear equation usually has not more than two variables. It is not complex or difficult to solve.
Example: 2x + 6y = 43z is NOT a linear equation.
