We're are given the following system of linear equations:
What we'll do, is substitute the
in the second equation by the definition of
given in the first equation (
):
We solve for
from the previous equation:
Now we know
.
In order to get the numerical value of
we use the fact that
in the first equation:
So
.
The answer is n=-2 and m=3.
D doesn’t show a positive or negative correlation. D is the best answer choice.
Answer:
(x+5)^2 = 1
Step-by-step explanation:
x^2+10x+24 = 0
Subtract 24 from each side
x^2+10x+24 -24 = 0-24
x^2+10x = -24
Take the coefficient of x
10
Divide by 2
10/2 =5
Square it
5^2 = 25
Add it to each side
x^2+10x+25 = -24+25
Take the coefficient divided by 2 inside the factor
(x+10/2) ^2 = -24+25
(x+5)^2 = 1
Answer/Step-by-step explanation:
✔️Find k:
Reference angle = 60°
Hypotenuse = k
Opposite = 9
Therefore, using trigonometric ratio, we have:
Multiply both sides by k
Divide both sides by sin(60)
Rationalize
✔️Find f:
Reference angle = 60°
Opposite = 9
Adjacent = f
Therefore, using trigonometric ratio, we have:
Multiply both sides by f
Divide both sides by tan(60)
Rationalize
