X=-4             you have to substitue first so you put the equation where the X is and then you would distribute and then add the numbers that have the common exponent

Solve the equation by completing the square. If necessary, round to the nearest hundredth.
diamong [38]
Ax^2+bx=c
REMEMBER THIS

ok
first, make sure that a is 1
done

now take 1/2 of b and square it

-18/2=-9, (-9)^2=81
add that to both sides

x²-18x+81=19+81
x²-18x+81=99
factor perfect square
(x-9)²=100
square root both sides
don't forget positive and negative root
x-9=10
x-9=-10
ad 9 to both sides

x=19
x=-1




answer is -1; 19

An adult stingray can measure about 350 cm long. how many meters is 350 cm?
Liono4ka [1.6K]

Answer:

<u>3.5 meters</u>

Step-by-step explanation:

1 meter = 100 centimeters

multiply both sides by 3.5 because we are trying to get 350 cm in meters.

1 x 3.5 meters = 100 x 3.5 centimeters

<u>3.5 meters </u>= 350 centimeters

(10-P) Help please, thanks.

The formula of linear equation is:
y1  -  y2 = m(x1  -  x2)
Where
x1 and x2: x coordinates(-1 and 3)
y1 and y2: y coordinates(-2 and 10)
m is the slope

We can then choose a point from the line to find the eqaution.

We need to first find the slope:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{ - 2 - 10}{ - 1 - 3}   \\ =  \frac{ - 12}{ - 4}  \\  = 3

In this case, as the y2 is given as 1,put (-1,-2) , and the slope(3 )into the eqaution :

y-(-2) = 3(x-(-1))
y+2 = 3(x+1)

Therefore
y + 2 = 3x + 1
is the answer.

Hope it helps!
