Answer:
Step-by-step explanation:
hello :
the slope for the line :3x+y=5 is : -3 because you can write y = -3x+5
the equation is : y= -3x-7
the line passes through (-1,-4) ( because when x=-1 y=-3(-1)-7 =3-7=-4) and parallel to the line 3x+y=5 have same
slope : -3
Answer:
Quotient: d = 1
Step-by-step explanation:
If we apply the formula
(D / d) = C + (R/d)
then
(x-6)/(x-8) can be rewrite in a way that is more convenient
(x-8+2)/(x-8) = (x-8)/(x-8) + (2/(x-8)) = 1 + (2/(x-8))
we can say that
C = 1 (the quotient)
and R = 2 (the rest)
Answer:
Step-by-step explanation:
a² + b² = c²
or in the case of a square where a and b are identical
2a² = c²
a = √(c²/2)
a = √(30²/2)
a = √450
a = 21.213203...
a = 21 m

Answer:
x²+2x+3
Step-by-step explanation:
We are to simplify the expression;
5x³+10x²+15x/5x
Factor out 5x from the numerator
= 5x(x²+2x+3)/5x
5x will cancel out both at the top and bottom to have;
x²+2x+3
Factorize
x²+2x+3
Hence the simplified form is x²+2x+3
