Step-by-step explanation:

$f(x)=\dfrac{x^2-4x+2}{x+7}\\\\f(-1)=\text{put}\ x=-1\ \text{to}\ f(x):\\\\f(-1)=\dfrac{(-1)^2-4(-1)+2}{-1+7}=\dfrac{1+4+2}{6}=\dfrac{7}{6}$

Answer: C is closest to the correct answer

<u>Step-by-step explanation:</u>

Convert the inches into feet (12 inches equal 1 foot). Then convert the mixed fractions into improper fractions and multiply.

$11\ ft\ 2\ in=11\dfrac{2}{12}ft\qquad\longrightarrow \qquad11\dfrac{1}{6}ft\qquad =\qquad \dfrac{67}{6}\ ft\\\\\\9\ ft\ 10\ in= 9\dfrac{10}{12}ft\qquad\longrightarrow \qquad9\dfrac{5}{6}ft\qquad =\qquad \dfrac{59}{6}\ ft\\\\\\\dfrac{67}{6}\ ft\times \dfrac{59}{6}\ ft\times \dfrac{\$2.50}{ft^2}=\dfrac{\$9,882.50}{36}\qquad \longrightarrow \qquad \large\boxed{\$274.51}$

Solve for z. 8z − 4 = 7z

aleksandr82 [10.1K]

8z − 4 = 7z

move 8z to the other side

sign changes from +8z to -8z

8z-8z-4=7z-8z

-4= 7z-8z

-4= -z

mutiply both sides by -1 to get +z

(-4)(-1)= (-z)(-1)

Answer:

z= 4

Which statement describes the solutions of the equation? 4x/3x+1 = x/2x+10

stiks02 [169]

Answer:

<h3> The equation has one valid solution and no extraneous of solutions.</h3>

Step-by-step explanation:

Given the expression;

4x/3x+1 = x/2x+10

We are to get the nature of the value of x

Cross multiply;

x(3x+1) = 4x(2x+10)

3x²+x = 8x²+40x

Collect like terms;

3x²-8x² + x - 40x = 0

-5x²+x -40x = 0

-5x²-39x = 0

-5x² = 39x

-5x = 39

x = -39/5

<em>Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.</em>
