Answer:

Givens

  • The ratio of trombones to violas is 1 to 3, that is, for every trombone there are 3 violas. \frac{t}{v}=\frac{1}{3}

So, if there are 9 violas, the number of trombones is three, because 9 violas represents a triple proportion, which means we need to multiply by 3 to find the number of trombones according to the given proportion.

\frac{t}{9}=\frac{1}{3}\\t=\frac{9}{3}\\ t=3

The expression that gives the number of trombones is

\frac{t}{9}=\frac{1}{3}

The number of trombones is 3, there are 3 trombones while there are 9 violas.

The proportion would be 1/3 and x/9. Cross multiplication creates 3x=9. Divide both sided by three, and there are 3 trombones in the orchestra.

Graph each equation.<br><br> y=-2x-1 <br><br> help please
yan [13]
You can graph that by looking at the y-intercept first. That's where you start to put a point in the coordinate plane or graph.

So go down 1 below 0.

Next, look at the slope.
We know that y = -2x - 1 is in slope intercept form (y = mx+b)
So -2 is our slope. It will be -2/1 because we need a fraction to graph the rise over run and all whole numbers can be a fraction by making 1 as their denominator.

Look at the attachment. 

Starting from -1 (y-intercept), go down 2 (-2) then right 1 (1).
To complete the line above, keep the same value and reverse their sign/symbol. So -2/1 will be 2/-1. It goes up 2 then left 1.

I hope you understand and find this answer the most helpful! :)

What are the solutions of the equation x4 + 6x2 + 5 = 0? Use u substitution to solve.
klio [65]

Answer:

x = i and x = i\sqrt{5}

Step-by-step explanation:

Given

x^{4} + 6x² + 5 = 0

Using the substitution u = x², then

u² + 6u + 5 = 0 ← in standard form

(u + 1)(u + 5) = 0 ← in factored form

Equate each factor to zero and solve for u

u + 1 = 0 ⇒ u = - 1

u + 5 = 0 ⇒ u = - 5

Convert solutions back into terms of x

x² = - 1 ⇒ x = \sqrt{-1} = i

x² = - 5 ⇒ x = \sqrt{-5} = i\sqrt{5}
