Answer:
1.45
2. 135
Explanation:
1. With a triangle all angles have to add up to 180, so what you would do is add up both angles we already know (43+92=135), then we subtract the sum from 180, (180-135=45) now you know the third angle.
2. Just like a triangle, when finding angles on a line, it has to add up to 180. We already know that point M has an angle of 45 from the last problem, so all we have to do is subtract 45 from 180 (180-45=135). THats the measurement on TMS

Find the explicit formula for
arithmetic
sequences.
38, 238, 438, 638, ..
Answers
Answer:
200n - 162.
Step-by-step explanation:
first trem a1 = 38
common difference d = 200
nth term = a1 + (n-1(d
= 38 + 200(n-1)
= 200n - 162
The explicit formula for arithmetic sequences is 200n - 162.
What is an arithmetic sequence?The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given sequence is 38, 238, 438, 638,
first trem a₁ = 38
Common difference d = 200
nth term = a₁ + (n-1(d
nth term = 38 + 200(n-1)
nth term = 200n - 162

Will give brainliest!!! The MTC Theater holds 250 people, and last night’s performance sold out! Students under the age of 16 paid $2.50 per ticket, while everyone else paid $4.00 per ticket. Last night’s show brought in $910.
Write a system to represent the given equations.
How many adult tickets were sold?
How many under the age of 16 tickets sold
Answers
Step-by-step explanation:
Let the no. of adult tickets sold be 'a'
Let the no. of children tickets sold be 'c'
Total tickets sold = 250
Cost of 1 children ticket = $2.5
Cost of 1 adult ticket = $4
Total money collected= $910
Given that,
a + c = 250
a = 250 - c
4a + 2.5c = 910
Substitute a value
4(250 - c) + 2.5c = 910
1000 - 4c + 2.5c = 910
1000 - 1.5c = 910
-1. 5c = -90
1.5c = 90
c = 90/1.5
c = 60
a + c = 250
a + 60 = 250
a = 190

A system of equations is given below:

Nicole says she would multiply the first equation by 3 and add the two equations together to eliminate the x's. Michael says he would multiply the first equation by 2 and add the two equations to eliminate the y's.
Who is correct? and explain why.
Answers
Answer:
Nicole is correct
Step-by-step explanation:
by multiplying the first equation by 3 it becomes:
3x + 6y =21
this can cancel the -3x in the second equation when adding them together
Answer:
Nicole is correct, since when she multiplied by 3, she cleared the x's, since one x was already negative, and the other one was positive. Michael is incorrect since when he multiplied by 2, he didn't realize that both y's were positive, so they didn't clear.
Step-by-step explanation:
Let's see what will happen if we do what Nicole says:
x+2y=7
-3x+4y=9
multiply the first equation by 3 on both sides
3(x+2y)=7(3)
3x+6y=21
-3x+4y=9
now let's add them.
10y=30
We can see that the x's are cleared, since one x is positive and the other is negative.
Now let's try what Michael says.
x+2y=7
-3x+4y=9
multiply first equation by 2
2(x+2y)=7
2x+4y=7
-3x+4y=9
now let's add
-x+8y=16
the y's aren't eliminated, since both of them are positive.
Nicole is correct, since one x is positive and another was negative, and when opposite numbers are added together, they cancel out and equal zero.
Hope this helps!

Solve the system using elimination,
2x - 3y = - 19
7x + 7y = 21
Answers
Answer:
x = -2
y = 5
Step-by-step explanation:
2x - 3y = -19 ---------------------------(I)
7x+ 7y = 21 -----------------------------(II)
Multiply equation (I) by 7 and equation (II) by 3.Then add and so y will be eliminated and you will get the value of x
(I)*7 14x - 21y = - 133
(II)* 3 21x + 21y = 63 {Now add}
35x = -70
x = -70/35
x = - 2
Plug in x = - 2 in equation (I)
2*(-2) - 3y = -19
-4 - 3y = -19
-3y = -19 + 4
-3y = -15
y = -15/-3
y = 5

~AH1807A rectangle has a length of (2x-7) and a width of (x+5) perimeter
Answers
Answer:
6x - 4
Step-by-step explanation:
Perimeter is equal to double the length plus double the width, and if you use this to find perimeter, you would get that the perimeter = 2(2x-7)+2(x+5), which simplifies to 4x - 14 + 2x + 10, which simplifies to 6x - 4. That means that the rectangle's perimeter is 6x-4.

Hi, how to do question 10:)?
Answers
Step-by-step explanation:
For the cubic function to be an increasing function, dy/dx > 0 for all real values of x.
dy/dx
= d/dx [4x³ + 4px² + 16x - 9]
= 12x² + 8px + 16.
We have 12x² + 8px + 16 > 0.
=> 3x² + 2px + 4 > 0,
where a = 3, b = 2p and c = 4.
For the quadratic function to have a range that is always positive, the discriminant must be less than 0.
(in order to have no real roots)
We have b² - 4ac < 0.
=> (2p)² - 4(3)(4) < 0
=> 4p² - 48 < 0
=> p² - 12 < 0
=> p² < 12
=> -√12 < p < √12
=> -2√3 < p < 2√3.
That was a very long process but hopefully you understand all of it!
