Answer:
1/(3x) =(x -2)/(4x^2 +9)
Step-by-step explanation:
The denominator cannot be factored further, so the final form will be ...
A/(3x) + (Bx +C)/(4x^2 +9)
The value of this is ...
(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))
= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))
Equating coefficients gives ...
3B+4A = 7
3C = -6 ⇒ C = -2
9A = 9 ⇒ A = 1
Using the found value of A, we find ...
3B +4 = 7 ⇒ B = 1
Then the decomposition is ...
1) Slope equals -0.667/2.000=-0.333
x-intercept =12/1=12.00000
y-intercept =12/3=4
x+3y=12
Answer: 4
2) Slope equals 2
x-intercept=5/2=2.5000
y-intercept=5/-1=-5.00000
Answer: -5.00000
Answer:
X=-3
X+3=0
Step-by-step explanation:
Yhat is the equation
For this case we can model the problem as a rectangle triangle.
We have two sides.
We want to find the hypotenuse of the triangle.
We have then:
h = root ((a) ^ 2 + (b) ^ 2)
Substituting values we have:
h = root ((6) ^ 2 + (8) ^ 2)
h = root (36 + 64)
h = root (100)
h = 10
Answer:
If you could walk straight from one school to the other, the 2 schools would be at:
h = 10 blocks
18 line segments also for faster and better u can 6 times 3 since there is already three in a triangle.
