Find the indicated values, where g(t)=t^2-t and f(x)=1+x g(f(2)+3)

sleet_krkn [62]

Answer:

$g(f(2)+3)=30$

Step-by-step explanation:

We have the two functions:

$g(t)=t^2-t\text{ and } f(x)=1+x$

And we wish to find:

$g(f(2)+3)$

First, let’s find f(2) first. So, we will substitute 2 for x for f(x):

$f(2)=1+(2)=3$

Hence, we can now substitute 3 for f(2):

$g(f(2)+3)=g(3+3)=g(6)$

Now, we can find g(6). Substitute 6 for t for g(t):

$g(6)=(6)^2-(6)=36-6=30$

Therefore:

$g(f(2)+3)=30$

The vertices of a parallelogram are A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4). Which of the following must be true if paral

d1i1m1o1n [39]

Answer:

The following points are not arranged in a parallelogram or rectangle order.

Step-by-step explanation:

Well first we need to graph the following.

A(1,1) B(2,2) C(3,3) D(4,4)

By looking at the image below we can tell it is not any shape, it’s not a parallelogram or a rectangle.

It is a line with a slope of 1 or x.

Find the equation of the linear function represented by the table below in slope-

pav-90 [236]

Answer: $y=-3x-2$

Step-by-step explanation:

Using the values $x=-2, y=4$ and $x=1, y=-5$ , the slope is $\frac{-5-4}{1-(-2)}=-3$ .

So, the equation is:

$y-4=-3(x+2)\\\\y-4=-3x-6\\\\y=-3x-2$
