Answer:

<h2>x = -5</h2><h2>y = -2</h2>

Step-by-step explanation:

$\left\{\begin{array}{ccc}3x+4y=-23&(1)\\x=3y+1&(2)\end{array}\right\\\\\text{Substitute (2) to (1):}\\\\3(3y+1)+4y=-23\qquad\text{use the distributive property}\\\\(3)(3y)+(3)(1)+4y=-23\\\\9y+3+4y=-23\qquad\text{subtract 3 from both sides}\\\\13y=-26\qquad\text{divide both sides by 13}\\\\\boxed{y=-2}\\\\\text{Put the value of }\ y\ \text{to (2)}:\\\\x=3(-2)+1\\\\x=-6+1\\\\\boxed{x=-5}$

A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m. report you

jeka94

It is given in the question that

A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m.

So we need to convert miles per hour to meters per second.

And it is given that 1 mile equals to 1610 meters and 1 hour equal to 3600 seconds.

So we will get

$657mi/hour = \frac{657*1610}{3600} m/seconds = 293.825m/s$

Let f(x) = x ^ 2 - x - 2 and g(x) = - 6x - 8. Find g(2) and f(g(2)). Mathfrak g (2)= Box (Simplify your answer. ) f(g(2)) = ( Si

The value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.

<h3>What is composite function?</h3>

When a function is written inside the another function, then such function is called the composite function.

The first function given in the problem is,

$f(x) = x^2 - x - 2$

The second function given,

$g(x) = - 6x - 8$

To find out the value of g(2), put the 2 on place of variable x in the above equation as,

$g(2) = - 6(2) - 8\\g(2)=-12-8\\g(2)=-20$

The composite function f(g(x)) can be given as,

$f(g(2))= (-20)^2 - (-20) - 2\\f(g(2))=418$

Thus, the value of the function f(g) after simplifying and putting 2 in place of <em>x</em> is -20 and the value of f(g(2)) is 418.
