Answer:
(-x)(x^2 + 4x + 5)
Step-by-step explanation:
You have to factor out the -x from the rest of the expression.
Answer:
x^2+17x+91=0
a = 1; b = 17; c = +91;
Δ = b2-4ac
Δ = 172-4·1·91
Δ = -75
Delta is less than zero, so there is no solution for the equation
Step-by-step explanation:
Answer:
2nd option
Step-by-step explanation:
r + 1 = 23 ( subtract 1 from both sides )
r = 22 ( multiply both sides by 3 to clear the fraction )
r = 66 ( divide both sides by )
r = 
× 
( rationalising the denominator )
r = 
= 33
The slope of the line we seek must me the same as the slope of the given line because THE LINES ARE PARALLEL.
The two lines never meet.
The slope of the given line is -7.
See it?
Plug -7 and the given point into the point-slope formula.
y - (-6) = -7(x - 9)
Solve for y.
y + 6 = -7x + 63
y = -7x + 63 - 6
y = -7x + 57
