Given: ∠ABC is a right angle and ∠DEF is a right angle.
Prove: All right angles are congruent by showing that ∠ABC ≅∠DEF.
What are the missing reasons in the steps of the proof?
A flow chart with 4 boxes that are labeled Given, A, B, C from left to right. Box Given contains angle A B C, angle D E F are right angles. Box A contains m angle A B C = 90 degrees and m angle D E F = 90 degrees. Box B contains m angle A B C = m angle D E F. Box C contains angle A B C is-congruent-to angle D E F.
The missing reasons in proving that all right angles are congruent are:
A. Definition of right angles
B. Substitution property
C. Congruent angles
What are Right Angles?Right angles are angles that measure 90 degrees. If two angles have the same 90 degrees, then they are congruent.
Thus, in the proof given, we have the following statements and their respective reasons:

C=85x+60
Solve the equation for x
Answer:
( C - 60)/ 85 = x
Step-by-step explanation:
C=85x+60
subtract 60 from each side
C-60=85x+60-60
C - 60 = 85x
Divide each side by 85
( C - 60)/ 85 = 85x/85
( C - 60)/ 85 = x
The discriminant of a quadratic equation is 34. Which of the following is true about its roots? *
a.The roots are imaginary and unequal.
b.The roots are real, rational, and unequal.
c.The roots are real, irrational and unequal.
d.The roots are real, rational and equal.
Answer:
d. The roots are real, rational and equal.Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers
Your soccer team isnt holding a silent auction dinner as a fundraiser to pay for school uniforms. The list shows all the expenses for the silent auction, 1) a tablet costs $280 2) football tickets that cost $100 3) a gift card that cost $20 4) the cost of the food is $400. The members of the soccer team will be selling tickets to the silent auction. A ticket to the silent auction includes chances to win prizes and dinner. The ticket cost is set so that 50 tickets will pay for the cost of food and prizes and food. Part a determine the cost per ticket. Part B build a function that can be used to find the total profit, f(x), the soccer team earns by selling x tickets. Show your work to build a function. Part C your soccer team needs to raise at least $300 more than the total cost of the expenses. What is the minimum number of tickets that must to be sold in order for your team to reach their goal? Use the mathematics to justify your response.
Answer:
A) $16
B) p(x) = 16x -800
C) 69 tickets
Step-by-step explanation:
A) The total of expenses is ...
$280 +100 +20 +400 = $800
If this is covered by 50 tickets, then a ticket must provide revenue of ...
$800/50 = $16
The cost per ticket is $16.
__
B) The profit is the difference between revenue and expenses. The revenue from sale of x tickets will be 16x. The expenses are fixed at 800, so the profit is ...
p(x) = 16x -800
__
C) We can find the number of tickets to sell (x) in order for profit to be at least $300 by solving the inequality ...
p(x) ≥ 300
16x -800 ≥ 300 . . . . . use the expression for p(x)
16x ≥ 1100 . . . . . . . . . add 800
x ≥ 68.75 . . . . . . . . . . divide by 16 . . . (the least satisfactory integer is 69)
In order to raise at least $300, the number of tickets sold must be at least 69.
Can someone help me? Thanks!!:)
Answer:
A
Step-by-step explanation:
We can try each option to see which one is correct.
System of Equations:
y > -2
x + y <= 4
Option A:
3 > -2 (true)
1 + 3 <= 4
4 <= 4 (true)
We do not need to test any more options since we already found the correct one.

C)19
D)55
2) M<3=37 find m<1
drawing not to scale
A)37
B)143
C)127
D)153
Answer:
A. C) x = 19
B. A) 37
Step-by-step explanation:
A. 7x - 8 = 6x + 11
7x - 8 - 6x = 6x + 11 - 6x
x - 8 = 11
x - 8 + 8 = 11 + 8
x = 19
B.
If m<3 = 37
<1 = <3
Therefore, m<1 must equal 37

If h and j are inverse functions, what is h(j(15))
Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.

Solve the equation y = ax − b for the variable x.
A. x = ya + b
B. x = a+by
C. x = y + ba
D. x = y+ba
Answer:
(y+b)/a = x
Step-by-step explanation:
y = ax − b
Add b to each side
y+b = ax − b+b
y+b =ax
Divide each side by a
(y+b)/a = ax/a
(y+b)/a = x
Answer:

Solve x-7y=16 for y
Answer:
y = (x-16)/7
Step-by-step explanation:
x - 7y = 16
~Subtract x to both sides
-7y = 16 - x
~Divide -7 to everything
y = (16-x)/7
Best of Luck!
Answer:
y = 1/7 x -16/7
Step-by-step explanation:
x-7y=16
Subtract x from each side
x-x-7y=16-x
-7y = -x+16
Divide each side by -7
-7y/-7 = -x/-7 +16/-7
y = 1/7 x -16/7
