Given :
segment AB = segment ADsegment BC = segment DC∠B =∠Dsegment AC bisects ∠BADThis means that △ABC≅△ADC under the SAS congruence criterion because according to this criterion if two sides and one included angle is equal two triangles are congruent and since these two triangles fulfill these rules they are said to be congruent under the SAS congruence criterion. But they are also congruent under the ASA congruence criterion which states that if two angles and one included side is equal two triangles are congruent. Since △ABC and △ADC fulfill these rules too they can said to be congruent under the ASA congruence criterion.

Solve the system of equations using substitution.
y = -7x
2x - y = -9
Answers
Step-by-step explanation:
Since y= -7x you will want to substitute the y in the other equation.
2x -(-7x) = -9
2x + 7x = -9
9x = -9
so x will be -1
y= -7(-1)
x= -1
y= 7
Answer:
x = -1 , y =7 (-1,7)
Step-by-step explanation:
[tex]y=-7x\\2x-y = -9\\[/tex]
[tex]2x+7x = -9[/tex]
[tex]2x+7x = 9x\\[/tex]
[tex]9x = -9\\[/tex]
[tex]\frac{9x}{9} =\frac{-9}{9}[/tex]
[tex]x = -1\\[/tex]

a function starts with f(x) so thats how i got the f(x) and im guessing this is talking about linear functions so they start of with 64 teams which is the y intercept and 1/2 are eliminated after each round which is -1/2 giving us f(x)= -1/2+64

Explain how to write and evaluate the algebraic expression 13 less than the quotient of forty and a number; evaluate when n=2
Answers
Answer:So you would start with 40/n because quotient means division and then it would be (40/n) - 13 (40 divided by n then minus 13) because the answer is thirteen less than the quotient of those numbers. since it wants you to evaluate for n=2 you would do 40/2 which is 20 then subtract 13 which is 7.
So write the expression as (40/n) -13 and when you evaluate just stick the 2 where the n is for (40/2) - 13
20 - 13
= 7
Step-by-step explanation: HOPE THAT THIS WILL HELP YOU ❤️
Answer:
Here's an answer I used <3
Explanation:
You would then get to 40/n because quotient means division, then 40/n-13 because the outcome is 13 below the quotient. You can divide 40 by 20 to get 20, then 13 to get 7 because it asks you to test n=2.
