Angles in a triangle add up to 180.
To find angle ACB:
180 - 83 - 47 = 50
So angle ACB = 50.
Angles on a straight line add up to 180 as well.
So to find angle BCD:
180 - 50 = 130
So angle BCD = 130, so the answer is D.

Write in point-slope form an equation of the line that passes through the point (1,9) with a slope of -2
Y-_=_(x-_)
Answers
Answer:
y - 9 = - 2(x - 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 2 and (a, b ) = (1, 9 ) , then
y - 9 = - 2(x - 1) ← is the equation of the line

change in y, for the first two pairs of coordinates?
of change, change in
Answers
Answer: The rate of change in the y coordinate is 75. 78 - 3= 75.
Answer:
Part a: Answer is 1/2
78 - 3/150 - 0 = 75/150
= 1/2
Part b: Answer is -1/2
3 - 78/300 - 150
= -75/150
= -1/2
Part c: No, the two rates aren’t the same, because one is positive and the other is negative.
Part d: The rate of change of the function determined by using the two pairs of coordinates is not the same. So, the function modeling the movement of the ball is a nonlinear function

After Gwen, Tristan, and Keith finish exercising, they go to the fair. At the fair, they each pay the entry fee and also buy tickets they can use for food or rides. Gwen pays the entry fee and buys 10 tickets. It costs her a total of $30. Tristan pays the entry fee and buys 15 tickets. It costs him a total of $40. Keith pays the entry fee and buys 10 tickets. It costs him a total of $30. In this task, you will create a system of equations and find the cost of each ticket. Let x represent the entry fee and y represent the cost of each ticket in dollars.
Answers
Answer:
Part A:
Gwen equation
x + 10y = 30
Part C:
Keith equation:
x + 10y = 30
Part B:
Tristan equation:
x + 15y = 40
Part D:
You would use Keith's and Tristan's equation, because Gwen and Keith have the same exact equation so you can just use Keith's equation.
Part E:
Multiply the second equation by -1, then add the equations together.
(x+10y=30)
-1(x+15y=40)
Becomes:
x + 10y = 30
-x - 15y = - 40
Add these equations to eliminate x:
-5y = -10
-5y/5 = -10/5
so y = 2
Now lets find x, so lets plug it in x + 10y = 30.
x + 10(2) = 30
x + 20 = 30 ( do 30-20)
x = 10
We used elimination to solve this problem.
The entree fee is $10 and each ticket costs $2.
Part F:
For this part search graph tool and go on the app, then put Keith's and Tristan's equation in Graph Tool. Once you do that just screenshot it and paste it to Part F, then your answer should be Yes, you get the same solution when it is solved algrebraically.

Blake has xx dimes and yy nickels. He has a minimum of 13 coins worth at most $1 combined. Solve this system of inequalities graphically and determine one possible solution.
Answers
Blake has 5 dimes and 10 nickels.
Let x represent the number of dimes and y represent the number of nickels.
Each dime is worth 10 cent ($0.1) and each nickel is worth 5 cents ($0.05).
Since he has a minimum of 13 coins, hence:
x + y ≥ 13 (1)
It is worth at most $1 combined, hence:
0.1x + 0.05y ≤ 1 (2)
From the graph, a possible solution is (5, 10).
