The actual distance from Chicago to Boston is 712.5 miles.

Step-by-step explanation:

Given,

Scale on map = 150 miles per inch

Distance from Chicago to Boston on map = 4.75 inches

Actual distance = Distance on map * 150 miles

Actual distance = 4.75 * 150

Actual distance = 712.5 miles

The actual distance from Chicago to Boston is 712.5 miles.

If f(x)=x+6 and g(x)=x^4 find G(F(x))
Novay_Z [31]

You plug in f(x) into where x is within g(x) so you get G(f(x))=(X+6)^4

Can anyone answer this please i need to be for sure I’m right
Genrish500 [490]
The answer to this question is B, (-infinity, -28]. 

We can get this answer by first multiplying each side of the inequality by 7. That would get rid of the fraction. When one does that, the result is d + 28 \leq 0. That means that d \leq -28. In interval notation, which is the notation the problem is asking us, that would be (-infinity, -28], since d is all values less than -28 this includes infinity, but it also includes -28, so there is a ] around it. That means that the answer to this question is B, (-infinity, -28].

does the following system of equations have a solution if so find it. 2x+y+z= 4 x-y+3z= -2 -x+y+z= -2
saul85 [17]
I'd suggest using "elimination by addition and subtraction" here, altho' there are other approaches (such as matrices, substitution, etc.).

Note that if you add the 3rd equation to the second, the x terms cancel out, and you are left with the system

 - y + 3z = -2
   y  + z  =  -2
-----------------
         4z = -4, so z = -1.

Next, multiply the 3rd equation by 2:  You'll get -2x + 2y + 2z = -2.

Add this result to the first equation.  The 2x terms will cancel, leaving you with the system

2y + 2z = -2
  y  +  z  = 4

This would be a good time to subst. -1 for z.  We then get:

-2y - 2 = -2.  Then y must be 0.  y = 0.

Now subst. -1 for z and 0 for y in any of the original equations.

For example, x - (-1) + 3(0) = -2, so x + 1 = -2, or x = -3.

Then a tentative solution is     (-3, -1, 0).

It's very important that you ensure that this satisfies all 3 of the originale quations.
