Answer:
y = -3x -5
Step-by-step explanation:
First subtract 3x from both sides
-y = 3x + 5
Then divide the - (1) from both sides
y = -3x - 5
Answer:
80 adults must addent to make a complete $1,000
Step-by-step explanation:
You start with the students, $3 for each and 200 of them attend. 3x200=600 dollars in total. Then you would subtract 600 from 1,000. Next you will do the adults, 5x80=400 (The "leftover" cash) $5 for each times 80 adults will be $400 in total.
Answer:
SAS theorem
Step-by-step explanation:
If 
and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.
So, and m∠ECD = m∠BCA because vertical angles are congruent
Therefore ΔECD is similar to ΔBCA by SAS theorem
Answer:
y = x+3; y = -2x +5
Step-by-step explanation:
x + 3 = -2x + 5
Let y = x + 3 = -2x + 5
If a = b = c then a=b and a=c
we can write the equation as
y = x + 3 and y = -2x + 5
Thus, this is the system of equations
y = x + 3
y = -2x + 5
