Answer:
y = (x+1)^2+5
Step-by-step explanation:
Add or subtract from both sides to complete the square;
y=x^2+2x+6; Subtract 5 from both sides
y-5 = x^2+2x+1; Factor;
y - 5 = (x+1)^2; Add 5 back to both sides;
y = (x+1)^2+5
Answer:
x = 6 , z = 79
Step-by-step explanation:
(8x + 53) and (6x + 43) are adjacent angles and sum to 180° , that is
8x + 53 + 6x + 43 = 180 , that is
14x + 96 = 180 ( subtract 96 from both sides )
14x = 84 (divide both sides by 14 )
x = 6
Then
6x + 43 = 6(6) + 43 = 36 + 43 = 79
z and 79 are vertical angles and congruent , then
z = 79
Answer:
y=3x-21
Step-by-step explanation:
a line is parallel if the slopes of the lines are the same
so that means that out line should look something like this
y=3x+b
then, we use our point given to find b
-3=18+b
b=-21
the equation of out line is y=3x-21
Answer:
30
Step-by-step explanation:
its basically 2x5x3 so that would equal 30
