Write an equation for a function that has vertical asymptotes at x=3 & x=-10

Answer:

\frac{5}{ {x}^{2}   + 7x - 30}

Step-by-step explanation:

We can write a rational function.

We need to make sure our denominator both have zeroes at 3 and 10.

Set an equation equal to zero to find the function

0 - x = 3

0 - x =  - 10

0 - ( - 3) =  = 3

0 - 10 = 10

So we would represent that's as

x - 3

and

x + 10

Multiply the two binomial together.

(x - 3)(x + 10) =  {x}^{2}  + 7x  - 30

Let our numbetator be any interger.

Use any equation as long as the quadratic is the denominator and the interger is the numerator.

\frac{5}{ {x}^{2} + 7x - 30 }

A number x is no more than 18. *write it as an inequality*
scZoUnD [109]

Answer:

x ≤ 18

Step-by-step explanation:

The ≤ symbol means "greater than or equal to". Since it is 'no more' than 18, that means it can be 18 or less. Thus, less than OR equal to. Hope I helped.

How do I solve an equation like this, one with a negative in front of parentheses?
azamat

The factor outside the parentheses is -1. Distribute using that factor.

2 - (4 - <em>x</em>) = 7<em>x</em> - 5<em>x</em>

<em />

-1 * 4 = -4 and -1 * -<em>x</em> = <em>x</em>

<em />

2 - 4 + <em>x</em> = 7<em>x</em> - 5<em>x</em>

Simplify.

-2 + <em>x</em> = 2<em>x</em>

<em>x</em> = 2<em>x</em> + 2

-<em>x</em> = 2

<em>x</em> = -2

<h3>Answer:</h3>

<em>x</em> = -2

18. Two planes left an airport at the same time. One flew north at a set speed and the other
Andre45 [30]

Answer: plane A = 333.33mph

Plane B = 500mph

Step-by-step explanation:

Given data:

Distance between the two planes = 2400miles.

Plane A flew North

Plane B flew south

Solution:

Let v represent plane A.

Let 2v represent plane B.

Distance between the two plane

v + 1.5* v = 3*v

7.5v = 2500miles

v = 333.33mph

Plane B has one and half times the speed of plane A

= 1.5 * 333.33

= 500mph
