${x}^{2} - 9x - 36 = 0 \\ (x - 12)(x + 3) = 0 \\ x - 12 = 0 \\ x = 12 \\ x + 3 = 0 \\ x = - 3$

X^2 - 9x - 36 = 0

Note that one possible set of factors is (x-12)(x+3). Why? Because (-12)(3) = -36 and -12x + 3x = -9x.

What is the exact solution to the equation 4^5x=3^(x-2)<br> list the steps to get the answer

scoray [572]

Answer: x = -0.377

Step-by-step explanation:

We have the equation:

4^(5*x) = 3^(x - 2)

Now we can use the fact that:

Ln(A^x) = x*Ln(A)

Then we can apply Ln(.) to both sides of the equation to get:

Ln(4^(5*x)) = Ln(3^(x - 2))

(5*x)*Ln(4) = (x - 2)*Ln(3)

(5*x)*Ln(4) - x*Ln(3) = -2*Ln(3)

x*(5*Ln(4) - Ln(3)) = -2*Ln(3)

x = -2*Ln(3)/(5*Ln(4) - Ln(3)) = -0.377

State which of the following sets of ordered pairs represent a function.

anastassius [24]

Answer:

d. Set A and Set B

Step-by-step explanation:

We have been given three sets:

Set A: (5, 2), (4, 3), (3, 4), (2, 5)

Set B: (-1, -6), (0, 2), (1, 2), (3, 6)

Set C: (2, 1), (4, 2), (2, 3), (8, 4)

Now we need to state about which of the following sets of ordered pairs represent a function.

We know that a function can't have repeated values in domain that is x-value can't repeat.

we see that set C has repeated x-value "2".

Then set C is not a function.

Hence correct choice is:

d. Set A and Set B

Answer:

s = 15

Step-by-step explanation:

We know that a straight line measures 180°

so… in order to find the value of s add the two angles with a sum of 180 and then solve for s

(9s + 8)° + 37° = 180°

Combine like terms

9s + 45 = 180

Subtract 45 from both sides

9s = 135

Solve for s

s = 135/9

s = 15
