Answer:

x = your number

3 / ( x + 8 ) = 2 / ( x + 3 )

Cross multiply

3 ∙ ( x + 3 ) = ( x + 8 ) ∙ 2

3 x + 9 = 2 x + 16

Subtract 2 x to both sides

x + 9 = 16

Subtract 9 to both sides

x = 7

A^2-12a+36 Factor. Check by expanding.

Jlenok [28]

a2 + 6a + 6a + 36

 a • (a+6)

 6 • (a+6)

 (a+6) • (a+6)

Multiply (a+6) by (a+6)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

The product is therefore, (a+6)(1+1) = (a+6)2

Final result : -1 • (a + 6)2

What is the order of the quadratic functions f(x)=−0.5x2,f(x)=14x2, and f(x)=x2 from the widest graph to the narrowest graph?

Irina18 [472]

Answer:

$f(x) = - 0.5 {x}^{2} \to \: f(x) = {x}^{2} \to \: f(x) = 14 {x}^{2}$

Step-by-step explanation:

The given quadratic functions are:

$f(x) = - 0.5 {x}^{2}$

$f(x) = 14 {x}^{2}$

$f(x) = {x}^{2}$

We want to order these functions, from the widest to the narrowest.

How wide the graph will open depends on the absolute value of the coefficient of the function.

The smaller the absolute value of the coefficient, the wider the graph.

Since

$| - 0.5| \: < \: |1| \: < \: |4|$

Therefore from the widest graph to the narrowest graph, we have:

$f(x) = - 0.5 {x}^{2} \to \: f(x) = {x}^{2} \to \: f(x) = 14 {x}^{2}$
