1/9 is a required answer.

Answer:

solution given:

$x^{-2}=\frac{1}{x²}$

again

substituting value of x

we have (-3)²=9

now

$\bold{\frac{1}{x²}=\frac{1}{9}}$

Rewrite an equation so does not have fractions 5/6x+2=3/6

Dovator [93]

Answer:

5x +12 = 3

Step-by-step explanation:

Multiply both sides of the equation by the least common denominator. Here, that is 6.

$\dfrac{5}{6}x+2=\dfrac{3}{6}\qquad\text{given}\\\\6\left(\dfrac{5}{6}x+2\right)=6\times\dfrac{3}{6}\qquad\text{multiply by 6}\\\\5x+6\times2=3\qquad\text{eliminate parentheses}\\\\\boxed{5x+12=3}}$

An architect planned to construct two similar stone pyramid structures in a park. The figure below shows the front view of the p

Sav [38]

Since the architect wants similar figures, it comes from the definition of similar triangles that the ratio of corresponding sides (all 3 sides) should be equal.

So,

$\frac{7.5}{6}= \frac{5}{4}= \frac{10}{CB}$ .

Let's find CB.

$\frac{7.5}{6} =\frac{5}{4}= \frac{10}{CB}\\ 1.25=1.25=\frac{10}{CB}\\ 1.25=\frac{10}{CB}\\ 1.25CB=10\\CB=\frac{10}{1.25}\\ CB=8$

So, CB should be 8. Option C is correct.

ANSWER: Change the length of side CB to 8 feet

George has $49 which he decides to spend on x and y. commodity x costs $5 per unit and commodity y costs $11 per unit. he has th

FromTheMoon [43]

We are given the equations:

5 x + 11 y = 49 --> eqtn 1

u = 3 x^2 + 6 y^2 --> eqtn 2

Rewrite eqtn 1 explicit to y:

11 y = 49 – 5 x

y = (49 – 5x) / 11 --> eqtn 3

Substitute eqtn 3 to eqtn 2:

u = 3 x^2 + 6 [(49 – 5x) / 11]^2

u = 3 x^2 + 6 [(2401 – 490 x + 25 x^2) / 121]

u = 3 x^2 + 14406/121 – 2940x/121 + 150x^2/121

u = 4.24 x^2 – 24.3 x + 119.06

Derive then set du/dx = 0 to get the maxima:

du/dx = 8.48 x – 24.3 = 0

solving for x:

8.48 x = 24.3

x = 2.87

so y is:

y = (49 – 5x) / 11 = (49 – 5*2.87) / 11

y = 3.15

Answer:

George will choose some of each commodity but more y than x.
