Solve for x:
x^2 + 10 x + 41 = 0
Subtract 41 from both sides:
x^2 + 10 x = -41
Add 25 to both sides:
x^2 + 10 x + 25 = -16
Write the left hand side as a square:
(x + 5)^2 = -16
Take the square root of both sides:
x + 5 = 4 i or x + 5 = -4 i
Subtract 5 from both sides:
x = -5 + 4 i or x + 5 = -4 i
Subtract 5 from both sides:
Answer:  x = -5 + 4 i or x = -5 - 4 i

lord [1]

Answer:

$16875

Step-by-step explanation:

Find the perimeter by adding all the lengths, which is 1875 ft.

Since 3ft = 1 yd, 1875/3 = 625 yds.

$27 per yard gives 625 * 27 = 16875.

Lines l and m are parallel and intersected by transversals t and s as shown in the figure below.
kogti [31]
Angle W and Y are right angles and equal to 90 degrees each. Angle z and angle x  are same side interior angles and they have a sum of 180 degrees because of the same side interior angles postulate.

so W= 90  Y=90   X+Z= 180 .  so 90+180+90 =360 degrees. B.

Y= -4x + 10? What is the slope of the line?
Salsk061 [2.6K]

Answer:

-4 or -4/1

Step-by-step explanation:

The equation is in y=mx+b form

m is the slope, and b is the y intercept

So, for this line, y=-4x+10

-4 is the slope and 10 is the y intercept

Hope this helps! :)
