Answer:

157

Step-by-step explanation:

Given 4(x^2+3)-2y, substitute -6 for x and -1/2 for y:

4([-6]^2 + 3) - 2(-1/2), or

4 (36 + 3) + 1, or

4(39) + 1, or, finally, 157.

What is one third plus one seventh
Kryger [21]
To do this, change into common denominators.  The common denominator is 21 so change the problem from 1/3 + 1/7 to 7/21 + 3/21.  This gives you 10/21.  It is already in simplest form.

Consider the graphs of f(x) and g(x).
butalik [34]

Answer:

The value of k is -7

Step-by-step explanation:

We are given the graph of f(x) and g(x). If g(x)=f(x)+k

If we shift f(x) k unit vertical get g(x).

If k>0 then shift up

If k<0 then shift down.

f(x) and g(x) are both parabola curve.

First we find the vertex of f(x) and g(x)

Vertex of f(x) = (3,1)

Vertex of g(x) = (3,-6)

We can see change in y co-ordinate only.

f(x) shift 7 unit down to get g(x)

g(x)=f(x)-7

Therefore, The value of k is -7
