Which statement about x2 + 10x = 11 is true?
1 answer:
Equations are statements that have equal values, when compared
The true statement about are x = 1 and x = -11
The equation is given as:
Rewrite as:
Expand
Factorize
Factor out x + 11
Solve for x
x = 1 or x = -11
Hence, the true statement about are x = 1 and x = -11

Answer:
Robyn and Vladimir both are correct.
Step-by-step explanation:
Vladimir says that the equation of the line the passes through points (-5, -3) and (10,9) is y = x + 1
Let's find the equation of line
Slope of the line passing through ( -5, -3 ) and (10, 9 )
So equation will be y = x + c
Since the line passes through (-5, -3)
so (-3) = x (-5) + c
(-3) = -4 + c
c = -3 +4 = 1
So equation should be y = x +1
Therefore, Vladimir is correct.
Robyn says this line is passing through (-10,-7) and (-15, -11)
Slope
equation is y = x + c
Since this line passes through (-10 -7)
so (-7) = x (-10) + c
-7 = -8 + c ⇒ c = 8 - 7 = 1
Equation of the line will be y = x + 1
So Robyn and Vladimir both are correct.
Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (23, - 30) and (x₂, y₂ ) = (- 7, 18)
m = =
=
= -
