Answer:

The ordered triple does not satisfy the system of equations

Explanation:

The given ordered triple satisfy the given system of equations if the substitution x = 0, y = -4, and z = 0 satisfy the equations simultaneously. If anyone fails, then it does not satisfy

For the first equation:

3(0)-2(-2)+4(0)=-4

This is satisfied

For the second equation:

-2=-\frac{0}{3}-2

This is also satisfied

For the third equation:

2(0)+2(0)=-4

This is NOT satisfied

Therefore, the ordered triple does not satisfy the system of equations

I believe the answer would be b^4.

Explanation:
Use Quotient Rule: x^a/x^b=x^a-b
b^10-6

Then Simplify 10-6 to 4
b^4

Solve for x in degrees: sinx=cos(48) without a calculator
Licemer1 [7]
We are given with the mathematical expression <span>sinx=cos(48) and is asked in the porblem to determine the value of variable x. In this case, we solve first cos 48 which is equal to -0.64. to determine x, we use inverse sin, that is sin-1 (-0.64) = x; x= 42 degrees. x is equal also to 90-48 according to complementary postulate.</span>

You are given n = 5 measurements: 5, 3, 3, 8, 8. (a) calculate the sample mean, x. (enter your answer to one decimal place.)
mojhsa [17]
The mean  = sum of all the measurements / number of measurements (n)

                 =  (5 + 3 + 3 + 8 + 8)  / 5

                 =   27 / 5

                 = 5.4  Answer

Given various values of the linear functions f(x) and g(x) in the table, determine the y-intercept of (f- g)(x).
lisabon 2012 [21]

The y-intercept of linear function (f- g)(x) is (0,9)

<h3>How to determine the y-intercept?</h3>

The table of values is given as:

x   -6 -4 -1 3 4

f(x) 15 11 5 -3 -5

g(x) -36 -26 -11 9 14

The equations of the functions is calculated using:

y = \frac{y_2 -y_1}{x_2-x_1} * (x -x_1) + y_1

So, we have:

f(x) = \frac{11 -15}{-4 + 6} * (x + 6) + 15

Evaluate

f(x) = -2x + 3

Also, we have:

g(x) = \frac{-26 + 36}{-4 + 6} * (x + 6) - 36

Evaluate

g(x) = 5x - 6

Next, we calculate (f - g)(x) using:

(f - g)(x) = f(x) - g(x)

This gives

(f - g)(x) = -2x + 3 - 5x + 6

Substitute 0 for x

(f - g)(0) = -2(0) + 3 - 5(0) + 6

Evaluate

(f - g)(0) = 9

Hence, the y-intercept of (f- g)(x) is (0,9)
